Privacy Policy

DailyRhythm is a local-first journal. Everything you log stays on your device unless you choose to send it somewhere. There are no accounts, no ads, no analytics and no DailyRhythm servers.

What the app stores

On your device only:

  • Moods, moments and tags you log.

  • Meals, food items, prices, calories and health tags.

  • Exercises, sleep, steps, weight and other health numbers you enter or import.

  • Your optional profile (birth year, height, weight, sex), used only to show reference ranges.

  • App settings.

Health Connect

If you turn on sync in Settings, DailyRhythm asks Health Connect for read-only access to:

  • Steps

  • Sleep

  • Resting heart rate

  • Exercise sessions, with their distance and calories burned

  • Past data (history), so a first sync can fill earlier days

This data is used only to show your days, metrics and garden inside the app. It is stored on your device, never written back to Health Connect, never sent to DailyRhythm or any third party, and never used for advertising. You can revoke access at any time in Health Connect.

DailyRhythm’s use of information received from Health Connect adheres to the Health Connect Permissions policy, including the Limited Use requirements.

What leaves your device, and only when you ask

  • Google Drive backup. If you sign in with Google and back up, a copy of your database is saved to a DailyRhythm_Backups folder in your Google Drive. The app can only see files it created there.

  • Calorie lookup. When you tap “Look up” on a food, only the food’s name is sent to Open Food Facts to search for calories.

  • Barcode lookup. When you scan or type a packaged food’s barcode, only the number is sent to Open Food Facts. The camera is used on the phone to read the code; no images are kept or sent.

  • AI assistant (optional). If you connect an AI model in Settings and tap “Estimate with AI” on a meal, only that food’s name is sent to the AI service you chose (a cloud provider or a server you run). To find the published figure, the AI may have your phone search for that food in Open Food Facts and, if you set it up, the web search service you chose; it may also open a web page from the results. Their terms apply. Your journal, moods and health data are never sent. Your API keys stay on your phone and are never exported or backed up. See AI assistant (optional).

  • Export. Files you export go wherever you save or share them.

Nothing is sent in the background.

Children

DailyRhythm is not directed at children under 13.
