Terms of Service

Last updated: 30 September 2026

1. About these terms

These terms apply to your use of the 3Sub app. The app is operated by Studio No. Limited, a company registered in England and Wales ("we", "us"). By downloading or using 3Sub you agree to these terms. If you do not agree, please do not use the app.

Our Privacy Policy explains how we handle your personal information. If you have any questions, contact us at support@3sub.app.

2. Your account

You can use 3Sub as a guest, or create an account with your email address, Sign in with Apple or Google Sign-In. You must be at least 13 years old to use 3Sub.

Guest data is linked to an anonymous account on this device. If you delete the app or sign out before creating an account, your guest data may not be recoverable.

You are responsible for keeping your sign-in details secure and for activity on your account. Tell us straight away if you think someone else has accessed it.

You can delete your account at any time from your profile in the Account tab. This permanently removes your account and subscription data from our servers and cannot be undone.

3. 3Sub Plus

3Sub Plus is an optional paid subscription that unlocks extra features and higher limits. The price, billing period and features are shown in the app before you buy.

Payment is taken by Apple from your Apple ID account when you confirm the purchase.
Your subscription renews automatically at the same price for the same period unless you cancel at least 24 hours before the current period ends. Your account is charged for renewal within 24 hours before the period ends.
If a free trial is offered, you will be charged when it ends unless you cancel at least 24 hours before then. Any unused part of a free trial ends when you buy a subscription.
You can manage or cancel your subscription at any time in your App Store account settings. Cancelling stops the next renewal; you keep Plus until the end of the period you have paid for.
Refunds are handled by Apple under its own policies. You can request one at reportaproblem.apple.com. We cannot issue refunds for App Store purchases.
If we change the price, Apple will tell you in advance and, where required, ask for your consent before you are charged the new price.

If your Plus subscription ends, everything you have added stays in your account. Anything above the free limits becomes view-only, and you can still delete it.

Some features may be offered free for a limited time, for example during a beta period, and later become part of Plus. Free and Plus limits and features may change over time, but we will not remove features you have already paid for during the period you have paid for.

4. Your data

The subscriptions, plans, notes and other information you add to 3Sub belong to you. You give us permission to store and process it only so we can run the app for you, for example to sync it across your devices and send your reminders.

You are responsible for the information you add. Please do not add anything unlawful or anything you do not have the right to use.

5. Information in the app

3Sub is a tracking tool. It does not manage, change or cancel your subscriptions with other companies, and it is not financial advice.

Service names, plan prices, exchange rates, statistics and details filled in by receipt scanning or "Say or Type it" are provided for guidance only and may be incomplete, out of date or wrong. Always check the details with the provider before relying on them.

Reminders are scheduled on your device and depend on your notification settings, the details you enter and your device working normally. We cannot guarantee that every reminder will arrive, and we are not responsible for charges, renewals or missed cancellations with other companies.

6. Acceptable use

You may use 3Sub for your own personal, non-commercial use. You must not:

copy, modify, decompile or reverse engineer the app, except where the law allows it;
try to get around usage limits, access controls or Plus features;
copy, scrape or extract the service and pricing catalogue in bulk;
interfere with, overload or try to gain unauthorised access to the app or its servers;
use the app for anything unlawful or harmful.

We may suspend or close accounts that break these terms. Where it is reasonable, we will tell you first and give you a chance to fix the problem.

7. Our content and other brands

The app, its design and our service and pricing catalogue are owned by us or our licensors. These terms give you a personal, non-exclusive, non-transferable licence to use the app on Apple devices you own or control, as permitted by the App Store terms.

Names and logos of other companies' services shown in 3Sub belong to their owners. They are used only to identify those services and do not mean that those companies endorse 3Sub.

8. Third-party services

Some parts of 3Sub rely on services from other companies, such as Apple, Google and currency rate providers. Your use of Sign in with Apple, Google Sign-In and the App Store is also governed by those companies' own terms. We are not responsible for websites or services outside 3Sub that the app links to.

9. Changes to the app

We are always improving 3Sub, so features may change, be added or be removed. We aim to keep the app available but cannot promise it will always be uninterrupted or error-free, and it may be unavailable during maintenance or for reasons outside our control.

If we ever decide to stop offering 3Sub, we will give you reasonable notice before the service ends.

10. Our responsibility to you

Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot be limited or excluded by law. Your legal rights as a consumer are not affected.

Subject to that, we are not responsible for:

loss or damage that was not reasonably foreseeable when you started using the app;
business losses, as 3Sub is for personal use only;
charges, renewals or missed cancellations with other companies, or decisions made using information shown in the app;
loss of data you add, unless it was caused by our failure to take reasonable steps to keep it safe.

Otherwise, our total liability to you is limited to the amount you paid for 3Sub Plus in the 12 months before the claim.

11. Apple

These terms are between you and us, not Apple. Apple is not responsible for the app or its content, and has no obligation to provide maintenance or support for it.

If the app fails to meet any applicable warranty, you may tell Apple and Apple will refund the purchase price, if any. To the extent allowed by law, Apple has no other warranty obligation for the app. We, not Apple, are responsible for handling any claims relating to the app, including product liability claims, claims that the app breaks consumer protection or other laws, and claims that the app infringes someone else's intellectual property.

You confirm that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties.

Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

12. Changes to these terms

We may update these terms from time to time, for example to reflect changes to the app or the law. We will change the "Last updated" date above and, for significant changes, let you know in the app before they take effect. If you do not agree to the new terms you can stop using 3Sub, cancel Plus and delete your account.

13. Governing law

These terms are governed by the laws of England and Wales, and the courts of England and Wales can hear any dispute. If you live in Scotland or Northern Ireland, you can also bring proceedings in your local courts. If you live elsewhere, you keep the protection of any mandatory consumer laws where you live.

If any part of these terms is found to be unenforceable, the rest stays in effect. If you have a problem with 3Sub, please contact us at support@3sub.app first so we can try to put it right.
