DoseDiary ("the app") is a personal medication reminder, built to collect as little as possible.
By default, everything — your medications, schedules, dose history, and profiles — is stored locally on your device and is never transmitted anywhere.
If you create an account and turn on cloud backup, your medication data is encrypted on your device (AES‑GCM, using a passphrase only you know) before it is uploaded to our backend (Google Firebase). We cannot read it — the encryption is zero‑knowledge and we never receive your passphrase.
If you turn on caregiver sharing, a summary of today's doses and missed‑dose status is shared only with the specific caregiver you invite via a one‑time code. You can enable "hide medication names" so only times and statuses are shared. Access is restricted to you and your linked caregiver.
If you turn on closed-app reminders (DoseDiary Pro), your dose times (not medication names, unless you use multiple profiles) and a push token are sent to our reminder service so notifications can reach your device when the app is closed. Turn the feature off and this data is deleted.
If you create an account, we store your email address and an authentication record through Google Firebase Authentication, solely so you can sign in and sync.
The camera is used only when you choose to attach a photo to a medication or dose. Photos are stored with your data (locally, and inside your encrypted backup if enabled).
DoseDiary is not directed to children under 13.
You can erase all local data anytime in Settings. To delete your cloud account and backup, see our account deletion page or contact us at the address below.
DoseDiary helps you track and remember medications. It is not medical advice and does not check drug interactions. Always follow your doctor or pharmacist.
