MedLog — Privacy Policy

Last updated 22 September 2026

Your health data stays on your phone. MedLog has no account, no server of its own, and no advertising. The developer cannot see your data and receives nothing from the app.

What is stored, and where

Everything you enter (patient details, medicines, doses, schedules, reminders, vitals, prescriptions and any documents you attach) is written to a database on your device only. That database is encrypted at rest, with a key held in the phone's own secure storage. No copy is sent anywhere automatically.

What leaves the device, and only when you ask

• Google Drive backup. If you turn it on and sign in, an encrypted backup file is placed in a hidden per-app folder in your own Google Drive. It is your Drive and your file. The developer has no access to it, and it is visible to no other app. The app requests only the drive.appdata scope, which cannot read the rest of your Drive.
• Backups, exports and shares. "Create Backup", "Export to Excel" and any share action produce a file that goes wherever you send it. Nothing is transmitted until you choose a destination.
• Medicine-name spelling suggestions. While you type a medicine name, just that text may be sent to the U.S. National Library of Medicine's public RxNav service (rxnav.nlm.nih.gov) to offer spelling corrections. No patient details, doses or identifiers are included, and nothing is sent when you are offline.

What is never collected

No analytics, no crash-reporting service, no advertising or advertising ID, no tracking across apps or websites, and no account. Nothing is sold or shared with third parties, because nothing is collected in the first place.

Permissions, and why they are asked for

• Microphone: to log a dose by speaking a medicine name. Speech is recognised by your phone's own speech service.
• Files: to pick a backup file when restoring your data.
• Notifications, exact alarms and vibration: to ring medicine reminders at the time you set, and to re-arm them after a restart.
• Internet: for the spelling lookup above, and for Google Drive backup if you use it.

Each permission can be refused and the rest of the app still works. They can be reviewed any time from Settings > Review app permissions.

Children

MedLog is not directed at children and collects nothing from anyone. A parent or carer may of course keep a child's medicine record in it.

Deleting your data

Uninstalling MedLog deletes the database and its encryption key from the phone, permanently. Export a backup first if you want to keep anything. A backup you placed in your own Google Drive is deleted from the app's Google Drive backup screen, or by removing the app's access in your Google Account settings.

Not medical advice

MedLog is a personal record-keeping and reminder tool. It does not diagnose, prescribe or give medical advice, and the ranges it uses to highlight a vitals reading are general reference values, not a clinical judgement. Always follow your doctor.
