3. In-app purchases

The App offers auto-renewing subscriptions and a one-time non-consumable purchase for Pro features. All purchases are processed by Apple. See our Terms of Service for full subscription terms, including auto-renewal, free-trial behavior, and cancellation procedure.

4. Health and medical disclaimer

The App provides sleep planning and circadian-rhythm guidance based on published research. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease. The guidance provided is general and may not be appropriate for your individual circumstances. Consult a licensed healthcare provider for medical concerns, including shift work sleep disorder and related conditions.

5. No warranty

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED OR ERROR-FREE.

6. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS OR REVENUES, WHETHER INCURRED DIRECTLY OR INDIRECTLY, OR ANY LOSS OF DATA, USE, OR GOODWILL. OUR TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT IS LIMITED TO THE AMOUNT YOU PAID US, IF ANY, IN THE TWELVE MONTHS PRECEDING THE CLAIM.
