Data sources and processors
Where ceria's data comes from and which services handle it.
Where data comes from
| Source | What ceria reads |
|---|---|
| Health Connect (Android) | The data types listed in the privacy policy, read-only |
| Garmin Connect | Daily summaries, sleep and activities, for the original single-user setup, through an unofficial connection that is being replaced by Health Connect |
| Garmin Connect (official API, when you connect it) | Activities, daily summaries and sleep you allow it to share, read-only. Not live yet; this line is here so the policy is ready once Garmin approves access |
| Withings | Weight and body composition, for the original single-user setup |
| Open Food Facts | Product names and nutrition for a barcode you scan. Only the barcode number is sent; it is not linked to you |
| Manual entries | Anything you type in yourself |
| Strava (when you connect it) | Activities you allow it to share. Not live yet; this line is here so the policy is ready when it is |
| Recipe web pages you import | The page at the address you paste, to read its recipe. The address and page are fetched by the ceria server and kept only as the recipe you save |
Who processes it
| Service | Used for | What it receives | Region |
|---|---|---|---|
| Supabase | Database and sign-in | Your account, profile, training, nutrition and health data | [region to be confirmed] |
| Cloudflare | Runs the ceria server and serves this site | Requests to ceria, which pass through it; it does not keep your health data | Global network |
| Anthropic | AI coaching and AI food-label reading, only when you use them | The question or photo you send plus the summary needed to answer it. Not your name or email | [region to be confirmed] |
| GitHub | Holds ceria's code and runs the scheduled sync for the original single-user setup | At present, the owner's own synced data files, until the sync moves to the new server | [region to be confirmed] |
| Health Connect on your phone, Google Play, and optional Google Calendar sync | Health Connect data stays on your phone until you allow ceria to read it. Calendar sync sends only the session titles and times you choose | Global |
Each service is used for the one purpose shown. If we add one, this page changes first and the app tells you.
