Terms of Use

Last updated: 3 September 2026 2026-05-02

By downloading or using the Kern app ("the app"), you agree to these terms. They are short on purpose.

License

Kern is licensed, not sold, to you for use only under these terms. The app and its content are owned by the developer and protected by copyright. You may use the app for personal, non-commercial purposes on devices you own or control.

Not medical advice

Kern is not a medical device, not a treatment program, and not a substitute for professional help. The app counts days since a date you enter and shows you milestone messages. It does not diagnose, treat, or cure any condition.

If you are recovering from substance use disorder, alcohol use disorder, or any other condition, work with a qualified healthcare provider, therapist, or recovery program. The app is a complement to real-world support, not a replacement for it.

If you are in crisis

The app is not equipped to respond to emergencies. If you are in crisis or thinking about hurting yourself, contact a crisis line immediately:

Or call your local emergency number.

Your data

The app stores all data locally on your device. We do not collect, transmit, or store anything on a server. See the Privacy Policy for details.

Purchases

Kern is free to use for one count, and stays that way. Keeping more than one count is Kern Pro, a single one-time purchase. There is no subscription and nothing renews.

The purchase is made through Apple, not through us. Apple takes the payment, holds the receipt, and is who you ask for a refund — we never see your card and cannot issue one. Restoring the purchase on another device you own, or after reinstalling, is free and is done with the Restore purchase button on the offer screen or in Settings.

Everything the app did before Pro existed stays free: your count, every widget, milestones, personal best, editing your own dates. If the purchase is refunded or lapses, nothing is deleted — your extra counts become read-only and remain yours to remove.

No warranty

The app is provided "as is" without warranty of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. The developer does not warrant that the app will be uninterrupted, error-free, or free of harmful components.

Limitation of liability

To the maximum extent permitted by law, the developer is not liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the app. Total liability for any direct damages is limited to the amount you paid for the app (currently zero).

Changes

We may update these terms over time. The "Last updated" date at the top reflects the most recent change. Continued use of the app after changes means you accept the updated terms.
