CycleCal is a wellness tool, not a medical device. Nothing in the App constitutes medical advice. Do not use CycleCal for contraception, pregnancy prevention, or to diagnose or treat any medical condition. Cycle predictions are estimates only. Consult a qualified healthcare provider for any medical concerns.

7. Disclaimer of Warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND.

OUR TOTAL CUMULATIVE LIABILITY SHALL NOT EXCEED THE AMOUNT YOU PAID US IN THE SIX MONTHS PRIOR TO THE CLAIM.

9. Apple-Specific Terms

You acknowledge that this EULA is between you and us only, not Apple Inc. Apple is not responsible for the App or its content. 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 will refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever regarding the App. Apple and its subsidiaries are third-party beneficiaries of this EULA and may enforce it against you.
