Zona Notify Terms of Service

Before you sign in to Zona or start using it as a guest on a device, the app shows these terms and the Zona Notify Privacy Policy when you choose how to sign in, and asks you to tick a box confirming that you have read and agree to both, and then to tap Agree and Continue; no account is created and no sign-in starts until you do. By agreeing, you also confirm that you meet the requirements in “Who can use Zona” below. The app asks again after we make a material change to either document, once you use a version of the app that includes it, and on a device where someone has signed out or deleted their account. By accepting these terms, or by using Zona, you agree to them. You may use Zona only if you agree to these terms. If you do not agree, do not use Zona. If you decline before signing in, no account is created and the app returns to the sign-in screen. If you decline while signed in, Zona stays closed on that device, and the app asks our server to stop sending alerts to it, until you agree; you can still sign out, or delete your account in Settings → Delete account and data. We keep a record of your acceptance as the Privacy Policy describes.

If you use Zona on behalf of an organisation, you confirm that you are authorised to accept these terms for it, and “you” includes that organisation.

You may not use Zona if the law that applies to you forbids it, or if we have previously ended your access.

Zona lets you create sources for the computers, scripts, services and AI agents you control. Each source has its own secret source key. A source sends an alert to Zona’s notification service, Zona stores the alert in your private inbox, and Zona then asks Expo’s, Apple’s or Google’s push services to notify your devices. You can read, pin, filter, export and delete alerts in the app. The features and limits of each plan are described in the app and on zonanotify.app, and they may change as these terms describe.

ZONA IS NOT AN EMERGENCY, MEDICAL, SAFETY-CRITICAL OR LIFE-SAFETY SERVICE, AND IT MUST NOT BE USED AS ONE.

Do not rely on Zona to protect life, health, property or the environment, to call for help, to monitor medical devices or industrial or safety systems, or for any purpose where a missed, late or incorrect alert could cause death, injury, or serious damage or loss. If an alert matters to you, keep an independent way to receive it, such as a separate monitoring or paging service, email, a phone call, or checking the system yourself.

Zona is provided on a best-effort basis. We do not guarantee that:

• an alert will be accepted, stored, delivered or shown, or that it will arrive within any particular time;
• a push notification will appear, make a sound or appear only once, or that alerts will appear in the order they were sent;
• the delivery status shown in the app is complete or up to date;
• the service, the API or the website will be available at any particular time, or free of errors, interruptions or data loss.

Alerts can be delayed, dropped, duplicated, shown late or shown out of order, for example because of network conditions, your device’s settings, Focus or battery-saving modes, rate and size limits, maintenance, or outages at Apple, Google, Expo, Supabase or other providers. Alerts and their images are kept only for your plan’s retention period, with the exceptions explained in the Privacy Policy, and are then deleted automatically. Zona is not a backup or archive service, so keep your own copy of anything you need.

You can use Zona as a guest, or with a recoverable account that uses a sign-in method we offer, such as email and password.

A guest account exists only in the app on the device where you created it. If you sign out of a guest account, or reset or lose the device, the guest account and its sources, alerts and settings can no longer be reached, and we cannot restore them. Deleting the app can have the same result; on iPhone and iPad the system may keep the sign-in, so that reinstalling Zona on the same device signs you back in, but do not rely on it. To keep them, add a sign-in method to protect the guest account first.

You are responsible for keeping your devices, sign-in methods and passwords secure, and for all activity in your account. Tell us promptly at terabasedevteam@gmail.com if you think someone has used your account without permission, and keep your account details accurate.

A source key is shown in full only once, when you create it. Zona stores only a one-way hash of it, and a short prefix that the app shows so that you can tell keys apart, and cannot show the key again. Treat every source key like a password:

• keep it secret, and do not put it in public code, logs, screenshots or alert text;
• you are responsible for every alert sent with your keys, whoever sends it, and an alert sent with one of your keys is treated as sent by you;
• if you think a key has been exposed, revoke it in the app immediately and create a new one.

We are not responsible for any loss caused by a key that you, or someone you gave it to, disclosed or failed to protect.

“Your content” means the alerts, titles, bodies, data, checklists, images, source names and any other material that you or your sources send to or create in Zona. You keep all the rights you have in your content.

You grant Terabase a worldwide, non-exclusive, royalty-free licence to host, store, copy, process, transmit and display your content, including through our service providers, only as needed to operate, secure and provide Zona to you and to comply with the law. The licence ends when your content is deleted from Zona, except for copies that remain for a limited time in backups or that we must keep by law.

You are responsible for your content and for everything your sources send. You confirm that:

• you have all the rights and permissions needed to send your content and to let us process it as these terms and the Privacy Policy describe;
• if your content contains personal data about other people, you have a lawful basis and have given any notice or obtained any consent the law requires, and you use Zona only for your own legitimate purposes;
• your content does not contain other people’s health, biometric, genetic, financial account or government identity data, or other sensitive or special-category data, personal data about a child other than yourself, or passwords, payment card details, live credentials or access tokens;
• your content is not unlawful, infringing, defamatory, harassing, threatening or deceptive, and you are allowed to share it.

We do not review content before it is stored, and we are not responsible for it. We may remove content, or restrict or suspend an account, if we reasonably believe that it breaks these terms or the law, or to respond to a valid legal request, and we will tell you why, as “Reporting content and complaints” describes.

If your content contains personal data about other people that you, or an organisation you use Zona for, control, you are the controller of that data and Terabase processes it on your behalf, as your processor. This section, with the rest of these terms and the Privacy Policy, is the written agreement for that processing. For that data, Terabase will:

• process it only to provide Zona as these terms, the Privacy Policy and your settings describe, which are your documented instructions, unless the law requires otherwise, in which case we will tell you first if the law allows;
• make sure that anyone we allow to process it is bound by confidentiality;
• protect it with the security measures described in the Privacy Policy;
• use only the service providers named in the Privacy Policy, under written terms that protect it, and announce any new provider by updating the Privacy Policy before it starts, so that you can object by stopping your use of Zona;
• transfer it outside your country only under the safeguards described in the Privacy Policy;
• help you, as far as we reasonably can, to answer requests from the people the data is about and to meet your obligations on security, breach notification and impact assessments;
• tell you without undue delay after we become aware of a personal data breach affecting it;
• delete it when you delete it, when your plan’s retention period ends or when your account is deleted, as the Privacy Policy describes, and give you the information you reasonably need to show that these obligations are met, including by answering written questions.

You are responsible for having a lawful basis for sending that data, for giving the people it is about any notice the law requires, and for the instructions you give through your settings.

Do not, and do not help anyone else to:

• use Zona in breach of any law, or for unlawful surveillance, tracking or monitoring of other people;
• send spam, malware or phishing, or use Zona to harass, threaten or deceive anyone;
• access or try to access another person’s account, sources, keys or data, or probe, scan or test the security of Zona without our written permission;
• get around rate limits, plan limits, payments or any other technical or usage restriction, or create accounts to avoid a limit or a suspension;
• load test, stress test, flood or overload Zona, or interfere with or disrupt the service, our providers or other users;
• scrape, crawl or harvest data from Zona or its website, other than by using the documented API with your own sources;
• copy, modify, decompile, disassemble or reverse engineer the apps or the service, except to the extent the law allows this despite this restriction;
• resell, sublicense or provide Zona as a service to others, or use it to build a competing product;
• send alerts to people who have not asked for them, or act on someone else’s behalf without their permission;
• use Zona in any way that could harm Terabase, our providers or other users.

If you believe that content in Zona is illegal or breaks these terms, email terabasedevteam@gmail.com with your name and email address, where the content is and why you believe it is illegal or breaks these terms, and a statement that you believe your report is accurate and complete. We confirm without undue delay that we have received your report, we handle it in a timely, diligent and objective way, and we tell you what we decided and how you can seek redress.

A person reviews every report and every complaint, and a person makes every decision to remove content or to restrict, suspend or end an account. Zona does not use automated means to moderate content or to make those decisions. The only automatic checks are technical ones that apply to every request alike: the limits on the size and format of what a source sends, and the rate and plan limits. They refuse a request that exceeds them and do not assess what the content means.

If we remove content, or restrict, suspend or end an account, we will tell the person affected and give our reasons, including the facts and the rule we relied on and how to contest the decision, unless the law or a risk to others prevents it. You can contest a decision about your content or account at the same address, and we will review it and tell you the outcome. You can also take any such decision to the courts. If you are in the European Union, you can also refer it to an out-of-court dispute settlement body certified under the Digital Services Act, where one is available for the dispute, and we will engage with that body in good faith as the law requires. Using either route does not affect your other rights.

That address is also our single point of contact for users and for public authorities, including under the European Union’s Digital Services Act. We handle messages in English and Chinese.

Zona Plus is an optional auto-renewable subscription, offered monthly or yearly, that adds features and higher limits. It is sold and billed by Apple through the App Store, and Terabase never receives your payment details.

• Your Apple Account is charged when you confirm the purchase. Prices are shown before you buy and may vary by country or region.
• The subscription renews automatically unless you cancel it at least 24 hours before the current period ends. Your Apple Account is charged for the renewal within 24 hours before the current period ends.
• You can cancel at any time in your Apple Account’s subscription settings. In Zona, open Zona Plus in Settings and choose Manage Subscription, which opens those settings. Cancelling stops the next renewal, and you keep Zona Plus until the end of the period you have paid for, unless Apple refunds or revokes the purchase earlier.
• Refunds, billing questions and price changes are handled by Apple under Apple’s terms and the law. If Apple refunds or revokes a purchase, Zona Plus may end immediately.
• When Zona Plus ends for any reason, alerts already in your inbox keep the deletion dates they had, so none is deleted early; the shorter retention period of your new plan applies only to alerts that arrive afterwards, as the Privacy Policy describes.
• Deleting your Zona account does not cancel your subscription; cancel it with Apple.
• We may change what Zona Plus and the free plans include, including their limits and retention periods. If we reduce Zona Plus in a way that materially affects you, we will tell you in the app before your next renewal so that you can cancel, and if the reduction takes effect during a period you have already paid for and Apple does not refund it, we will refund the unused part of that period to you on request, in proportion to the time left.
• We may provide Zona Plus features at no charge, for example to testers or during a promotion, and we may change or end that access at any time.

We may offer test builds, for example through Apple TestFlight or an Android preview, and features marked as preview, beta or experimental. They are provided as is, may not work reliably, may lose data, and may be changed or withdrawn at any time. TestFlight is also subject to Apple’s terms.

The Zona MCP server is published as open-source software under the MIT licence, and the Zona command-line tool and agent hooks will be published the same way when they are released (together, the “PC tools”); a copy of the licence comes with them. The MIT licence governs your use of that code. These terms govern your use of the Zona service through the PC tools, as through any other client.

The PC tools run on your computer, under your control. They read your source key from your home folder, or from an environment variable you set, and send alerts only to Zona’s notification service; once you install the agent hooks, they send one each time a connected AI agent finishes or needs your input. You are responsible for installing them, for the commands, scripts and AI agents you connect to them, and for everything they send.

The Zona apps include open-source components that are licensed under their own terms, listed at zonanotify.app/legal/licenses.

Zona depends on services that we do not control, including Apple (App Store, push notifications and Sign in with Apple), Google (push notifications on Android and Google sign-in), Expo (push delivery and app updates), Supabase (hosting, database, sign-in and storage), Cloudflare (the website) and GitHub (sign-in and public pages). Their availability, security and conduct are their responsibility, and your use of a sign-in provider or an app store is also subject to that provider’s own terms. If you got Zona from an app store other than Apple’s, such as Google Play, that store’s terms also apply to your download and purchases, and that store is not responsible for Zona. To the extent the law allows, we are not responsible for third-party services or for any loss they cause.

Terabase and its licensors own Zona, including the apps, the service, the website, their design, text and software, and the Zona, Zona Notify and Terabase names and logos. These terms do not transfer any of those rights to you.

Subject to these terms, we give you a personal, non-exclusive, non-transferable, non-sublicensable and revocable licence to install and use the Zona apps on devices that you own or control, and to use the service, for your own personal or internal business purposes. For the iOS app, this licence is also subject to the App Store’s usage rules. All rights not expressly granted to you are reserved.

If you send us ideas, suggestions or other feedback, you give Terabase a perpetual, irrevocable, worldwide, royalty-free licence to use, copy, modify and publish it for any purpose, without payment or attribution. You do not have to send feedback, and we do not have to use it.

You can stop using Zona at any time and delete your account in Settings → Delete account and data.

We may suspend, restrict or end your access to all or part of Zona if we reasonably believe that you have broken these terms, that your use creates a risk or possible legal exposure for Terabase, our providers or other users, or that we must do so by law. We will tell you our reasons, as “Reporting content and complaints” describes, unless the law or a risk to others prevents it. We may also stop offering Zona, or Zona Plus, altogether, or end this agreement with you for any other reason, by giving you at least 30 days’ notice in the app, by email to an address linked to your account or on zonanotify.app, or shorter notice where the law, a security risk or the loss of a provider we depend on leaves us no choice. That notice period does not apply to changes to individual features, limits and plans, which are made as “Changes to Zona and to these terms” and “Zona Plus” describe, or to interruptions for maintenance, security or outages, which “Delivery, availability and retention” covers. Once we have given notice that Zona Plus will stop, we will stop selling it and, where the App Store lets us, stop renewals. If Zona Plus stops, or we end this agreement for a reason other than your breach of these terms, before the end of a period you have already paid for, and Apple does not refund the unused part, we will refund it to you on request, in proportion to the time left.

We may also delete an account, with its data, that has not been opened in the app and has received no alerts for 12 months: a guest account without notice, because we have no way to reach it, and a recoverable account after we have emailed the address linked to it at least 30 days before.

When your access ends, your licence to use Zona ends, your source keys stop working, and your data is deleted or kept as the Privacy Policy describes. If we end your access because you broke these terms, you are not entitled to a refund. Otherwise, refunds are made only as this section and “Zona Plus” describe, or by Apple under its own terms and the law. The parts of these terms about your content, personal data in your content, feedback, disclaimers, limitation of liability, indemnity, the Apple App Store, general terms, notices, and governing law and disputes continue to apply after this agreement ends, together with any other part that by its nature should continue.

We may add, change or remove features, limits and plans, and we may update these terms, for example to reflect changes to Zona, to the law or to our providers. Each version of these terms has a version date. If we make a material change, we will tell you before it takes effect, in the app, by email to an address linked to your account or on zonanotify.app, and the app will ask you to accept the new terms when you next use a version of it that includes them. If you keep using Zona after a change takes effect, you accept the changed terms. Other changes take effect when we publish them. If you do not accept new terms, stop using Zona and delete your account.

TO THE FULLEST EXTENT PERMITTED BY LAW, ZONA IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. TERABASE DISCLAIMS ALL WARRANTIES, CONDITIONS AND OTHER TERMS, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, SATISFACTORY QUALITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, TITLE, QUIET ENJOYMENT OR NON-INFRINGEMENT, AND ANY WARRANTY ARISING FROM A COURSE OF DEALING OR USAGE OF TRADE.

WITHOUT LIMITING THE ABOVE, TERABASE DOES NOT WARRANT THAT ZONA WILL MEET YOUR REQUIREMENTS, THAT ANY ALERT WILL BE ACCEPTED, STORED, DELIVERED OR SHOWN ON TIME OR AT ALL, THAT ZONA WILL BE UNINTERRUPTED, SECURE OR ERROR-FREE, OR THAT ANY DATA WILL NOT BE LOST.

Some places do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you. See “What these terms do not limit” below.

Each exclusion and limit in this section is a separate term. If a court finds one of them unenforceable, the others still apply.

TO THE FULLEST EXTENT PERMITTED BY LAW, NEITHER TERABASE NOR ITS OWNERS, STAFF OR CONTRACTORS WILL BE LIABLE TO YOU, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), BREACH OF STATUTORY DUTY OR OTHERWISE, FOR ANY OF THE FOLLOWING, EVEN IF ANY OF THEM WAS TOLD THAT SUCH LOSS WAS POSSIBLE:

• INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE LOSS OR DAMAGE;
• LOSS OF PROFITS, REVENUE, BUSINESS, CONTRACTS, ANTICIPATED SAVINGS, GOODWILL OR REPUTATION;
• LOSS OR CORRUPTION OF DATA OR CONTENT;
• LOSS ARISING FROM AN ALERT THAT WAS NOT DELIVERED, OR WAS DELAYED, DUPLICATED, SHOWN LATE, SHOWN OUT OF ORDER OR SHOWN INCORRECTLY, OR FROM RELYING ON ZONA FOR A PURPOSE DESCRIBED IN “NOT FOR EMERGENCIES OR CRITICAL ALERTS”.

TO THE FULLEST EXTENT PERMITTED BY LAW, THE TOTAL LIABILITY OF TERABASE AND ITS OWNERS, STAFF AND CONTRACTORS, TAKEN TOGETHER, FOR ALL CLAIMS ARISING OUT OF OR RELATING TO ZONA OR THESE TERMS WILL NOT EXCEED THE GREATER OF HK$100 AND THE TOTAL AMOUNT YOU PAID FOR ZONA IN THE 12 MONTHS BEFORE THE EVENT THAT GAVE RISE TO THE CLAIM.

These limits reflect that Zona is run by a small independent business, is offered free or for a small subscription, and depends on networks and providers that we do not control. We could not offer Zona on these terms without them.

Nothing in these terms excludes or limits any liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or any other liability that cannot be excluded or limited by law, including under the Control of Exemption Clauses Ordinance (Cap. 71) and the Supply of Services (Implied Terms) Ordinance (Cap. 457) of Hong Kong. If you are a consumer, nothing in these terms affects the rights you have under the mandatory consumer law of the place where you live, and every exclusion and limit in these terms applies only to the extent that law permits.

To the extent the law allows, you will indemnify Terabase and its owners, staff and contractors against all claims, losses, liabilities, damages, costs and expenses, including reasonable legal fees, arising out of or relating to your content, the alerts sent by your sources or with your keys, your breach of these terms, or your violation of any law or of anyone else’s rights. We will tell you about any such claim. We may take control of its defence, and you will cooperate with us; this does not reduce your obligation to indemnify us, including for our reasonable legal fees. This indemnity does not cover any loss to the extent it is caused by our own breach or negligence.

This section applies if you got a Zona app from Apple’s App Store. If it conflicts with anything else in these terms, this section prevails.

• These terms are between you and Terabase only, not Apple Inc. (“Apple”). Terabase, not Apple, is solely responsible for Zona and its content.
• Your licence to use the iOS app is limited to Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that the app may be accessed and used by other accounts associated with you through Family Sharing or volume purchasing. The Apple Standard EULA also applies to the iOS app; if it conflicts with these terms about your licence to use the iOS app, the Apple Standard EULA governs to the extent of the conflict.
• Apple has no obligation to provide any maintenance or support services for Zona.
• If Zona fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the app, if any, to you. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to Zona, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to a warranty are Terabase’s responsibility, to the extent they are not excluded by these terms.
• Terabase, not Apple, is responsible for addressing any claims by you or any third party relating to Zona or your possession or use of it, including product liability claims, any claim that Zona fails to conform to any applicable legal or regulatory requirement, and claims under consumer protection, privacy or similar laws.
• If a third party claims that Zona, or your possession or use of it, infringes that third party’s intellectual property rights, Terabase, not Apple, is solely responsible for the investigation, defence, settlement and discharge of that claim.
• You represent and warrant that you are not located in a country that is subject to a U.S. Government embargo or that has been designated by the U.S. Government as a “terrorist supporting” country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
• You must comply with any applicable third-party terms, such as your wireless data service agreement, when you use Zona.
• Apple and Apple’s subsidiaries are third-party beneficiaries of these terms. When you accept these terms, Apple has the right, and is deemed to have accepted the right, to enforce them against you as a third-party beneficiary.
• Please send any questions, complaints or claims about Zona to Terabase, using the contact details below.

Zona may be subject to the export control and sanctions laws of Hong Kong, the United States and other countries. You must not use, export or re-export Zona in breach of those laws, and you confirm that those laws do not prohibit us from providing Zona to you.

We are not responsible for any failure or delay in providing Zona that is caused by events beyond our reasonable control, including failures or outages of internet, telecommunications, power, hosting or push notification providers, cyberattacks, natural disasters, epidemics, war, terrorism, civil unrest, labour disputes, and actions of governments or other authorities.

• Entire agreement. These terms, together with the Privacy Policy and, for the iOS app, the Apple Standard EULA where it applies, are the entire agreement between you and Terabase about Zona, and they replace any earlier terms. In accepting them, you have not relied on any statement or promise about Zona that is not in them or in the descriptions in the app and on zonanotify.app. This does not limit liability for fraud or fraudulent misrepresentation.
• Assignment. You may not transfer your rights or obligations under these terms without our written consent. We may transfer ours, for example to a company that takes over Zona, provided that your rights under these terms are not reduced as a result.
• Severability. If a court finds any part of these terms invalid or unenforceable, that part is limited or removed only as far as necessary, and the rest of these terms stays in effect.
• No waiver. If we do not enforce a right straight away, we can still enforce it later.
• Third-party rights. Except for Apple as described above, and for Terabase’s owners, staff and contractors, who may rely on “Limitation of liability” and “Indemnity”, no one other than you and Terabase has any right to enforce these terms, including under the Contracts (Rights of Third Parties) Ordinance (Cap. 623).
• Relationship. Nothing in these terms creates a partnership, employment, agency or joint venture between you and Terabase.
• Interpretation. Headings are for convenience only and do not affect the meaning of these terms. Words such as “including”, “such as” and “for example” introduce examples and do not limit the words before them.
• Language. These terms are written in English, and the English version governs. The Traditional Chinese version is a translation provided for convenience; if the two differ, the English version applies. If the app or the website shows you a summary of these terms, or other text about them, in another language, it is provided for convenience only, and these terms govern.

We may send you notices in the app, by email to an address linked to your account, or by publishing them on zonanotify.app. You can send notices to Terabase by email to terabasedevteam@gmail.com. A notice sent by email is treated as received when it is sent, unless the sender learns that it was not delivered.

These terms, and any dispute or claim arising out of or relating to them or to Zona, including non-contractual disputes or claims, are governed by the laws of the Hong Kong Special Administrative Region.

Before starting any proceedings, please contact us so that we can try to resolve the issue informally. If it is not resolved within 30 days, either of us may start proceedings. Either of us may still apply to a court for urgent interim relief, such as an injunction, without waiting for those 30 days. The courts of the Hong Kong Special Administrative Region have exclusive jurisdiction over any such dispute or claim.

To the extent the law allows, you and Terabase will each bring claims only individually, and not as a plaintiff or class member in any class, collective or representative action. To the extent the law allows, any claim must be brought within one year after the person bringing it became aware, or ought reasonably to have become aware, of the facts giving rise to it, or it is permanently barred; this time limit does not apply to claims by Terabase about infringement of its intellectual property, misuse of Zona, sums you owe us or your indemnity.

If you are a consumer and the law of the place where you live gives you the right to bring proceedings in your local courts or to rely on the mandatory protections of your local law, nothing in this section takes that right away.

Zona is provided by Terabase, Hong Kong. Email terabasedevteam@gmail.com. We do not publish a postal address; notices and requests are handled by email or through the app.
