Licence Agreement

Last updated: 25 August 2026

SlumberBrew

This agreement is between you and Cael Jones ("we", "us"), the developer of SlumberBrew. It is not with Apple. Apple is not a party to this agreement and has no responsibility for the app or its content.

1. Licence

We grant you a personal, non-transferable, non-exclusive licence to use SlumberBrew on any Apple-branded device you own or control, as permitted by the App Store Terms of Service. You may not sell, rent, sublicense, or redistribute the app.

2. What you may not do

You may not copy, modify, translate, reverse engineer, decompile or disassemble the app, or attempt to derive its source code, except where that restriction is prohibited by law.

3. Not a medical device

SlumberBrew estimates caffeine levels from what you tell it you drank, using published averages for caffeine content and a published pharmacokinetic model.

It is not a medical device and provides no medical advice. It does not diagnose, treat, cure or prevent any condition. Caffeine content in real drinks varies severalfold, and caffeine half-life varies severalfold between people, so the figures the app shows are estimates and may be wrong for you. Do not rely on them for any medical purpose. If you have a health condition, take medication, are pregnant, or have concerns about caffeine or sleep, consult a qualified healthcare professional.

4. Apple Health

If you connect Apple Health, the app reads your sleep data and, with your permission, writes the drinks you log as dietary caffeine. Health data is used only on your device to provide the app's features. It is never used for advertising or marketing, never sold, and never disclosed to a third party. You can withdraw either permission at any time in the iOS Settings app.

5. Your data

The app stores your data on your device. We do not operate a server that holds it and we cannot recover it if you delete it. See the Privacy Policy for full detail.

6. No warranty

The app is provided "as is" and "as available", without warranty of any kind, to the maximum extent permitted by law. We do not warrant that it will be uninterrupted or error free, or that its estimates will be accurate for you.

7. Limitation of liability

To the maximum extent permitted by law, we are not liable for any indirect, incidental, special or consequential damages, or for any loss arising from your use of the app or from decisions you make based on it. Nothing here excludes liability that cannot lawfully be excluded, including for death or personal injury caused by negligence, or for fraud.

8. Third-party terms

You must comply with any applicable third-party terms when using the app, including your wireless data plan terms.

9. Apple's role

You and we acknowledge that this agreement is between us only. Apple has no obligation to provide maintenance or support for the app. If the app fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price; to the maximum extent permitted by law, Apple has no other warranty obligation. We, not Apple, are responsible for addressing any claim relating to the app, including product liability claims, claims that the app fails to conform to a legal requirement, and claims arising under consumer protection or privacy law. Apple and its subsidiaries are third-party beneficiaries of this agreement and may enforce it against you.

10. Termination

This licence ends if you breach its terms. You may end it at any time by deleting the app.

11. Governing law

This agreement is governed by the law of England and Wales, without prejudice to the mandatory consumer protections of the country you live in.
