This website
- No cookies. None are set.
- No analytics, no tracking, no ads. The pages are plain files.
- Nothing loads from other servers. No fonts, no scripts, no pictures from anyone else.
- One thing is kept in your browser: if you press the theme button, your choice of light or dark is saved on your device, so the next page does not flash. It is never sent anywhere.
Like every web server, the machine that hosts these pages sees the address a request comes from. Nothing on this site adds to that.
The app
openNutrition is software you host yourself, or that someone you know hosts for you. So the person who runs the server looks after your data, not the openNutrition project. The project never receives it, because there is nowhere for it to go.
What is stored
Your account (email, name, password hash), your diary entries, recipes, saved meals, supplements and intakes, body weight, targets and settings. All of it sits in the database of the server you use.
Meal photos are stored only if you choose to keep them. By default they are deleted right after analysis.
What leaves the server
- Online food lookups: only the barcode or the search words you look up, when you scan or press the online search button. No account data.
- AI photo analysis, if the admin set it up: the meal photo you submit, resized and without metadata. If the model runs outside the server, you have to opt in first in Settings.
- Product pictures from Open Food Facts load from their servers when shown.
No tracking
No advertising, no analytics, no tracking pixels and no telemetry.
Your rights
Export everything as JSON, or as CSV for spreadsheets, and delete your account in Settings at any time. Deleting removes your data from the database. Backups the operator made may still hold it for a while. Each server's own privacy page says who runs it and for how long.
Not medical advice
openNutrition shows the data you enter and label data from public databases. Nothing in the app is medical or dietary advice.
Contact
About this website or the project: [email protected]. About your data on a particular server: ask the person who runs that server. Their name should be on the privacy page inside the app.
