Core Strength Daily ("the app") is a personal fitness program. We designed it to respect your privacy completely.
Nothing. Core Strength Daily does not collect, transmit, sell, or share any personal information. The app has no accounts, no login, and no analytics or tracking.
Your workout progress — which exercises you've checked off, your streak, and completed sessions — is stored only on your device using local storage. This information never leaves your phone and is not accessible to us or any third party. Deleting the app removes this data.
Some exercises include an optional "Watch how to do it" button that opens a video search on YouTube. If you tap it, you are subject to YouTube's and Google's privacy policies. Core Strength Daily does not share any information with them.
Core Strength Daily is intended for adults and does not knowingly collect information from anyone.
Core Strength Daily is a general fitness and conditioning program. It is not medical advice, diagnosis, or treatment. Consult a qualified healthcare professional before beginning any exercise program.
If this policy changes, the updated version will be posted on this page.
