Decades is a personal and multigenerational family health app. You can use it to manage your health profile, family health history, medications, supplements, doctors, insurance and ID documents, emergency information, reminders, calendar events, notifications, and AI-generated health insights.

You can create an account using email, Google, or Apple sign-in. After signing up, you may be asked to complete age verification and onboarding so Decades can set up your profile correctly. If you already have an account, use the same sign-in method you used originally. If you do not receive a verification email or cannot access your account, contact support at apps@decades.health.

Decades may require an active subscription or an invite code for access. If you already purchased access but it is not showing in the app, use the Restore Purchase option after signing in with the same account you used for the original purchase. Restoring only works for the original account and purchase record. If the issue continues, contact support with your account email and purchase date, but do not send raw receipts or purchase tokens unless support specifically requests a safe way to verify them.

Decades treats health and family information as sensitive data. The app uses authenticated accounts, secure local storage for sessions, restricted backend access controls, and private storage for documents. We also provide privacy and terms information inside the app and on the website. Decades is designed with privacy and security as core requirements.

You can delete your account and data from Profile Settings using the dedicated delete button.
