Your data, your account

A short, plain-English account of what LibreNomNom does and doesn't do with your data.

Isolated by user

Each account has its own private partition in Azure Blob Storage. Food entries, water logs, favorites, settings, and diet profile are scoped to your Firebase user id. No one else — not even the owner of the deployment — can read your log via the app's UI.

You bring your own AI key

The AI features (voice parsing, photo analysis, menu/barcode lookup, coaching chat) call Anthropic and OpenAI Whisper. You can paste your personal Anthropic API key in Settings → AI; it's stored only in your browser's localStorage and is sent only to the server function that proxies the call to Anthropic. The owner's deployment also has env-var fallback keys for convenience, but you can override them with your own at any time.

No tracking, no analytics

No third-party scripts, no behavior pixels, no marketing cookies. No Google Analytics, no Segment, no anything. Application Insights on the Azure Functions side records standard server-level errors and request rates (no message content, no food entries), used only for debugging crashes.

What's stored where

• Azure Blob Storage: food entries, water logs, favorites, diet profile, settings, AI usage counters (per user, partitioned by uid).
• Browser localStorage: your Anthropic API key (if you provided one), UI preferences (theme, last-used capture mode), the local cache for fast initial paint.
• Anthropic: only what you send when you trigger an AI feature — the food description you typed, the photo you snapped, or your chat message. They retain prompts per their own retention policy and do not use API data to train models.
• OpenAI Whisper: only the audio clip when you use voice capture. The clip is transcribed to text and not retained by LibreNomNom; OpenAI's retention policy applies during processing.
• Firebase Authentication: your email address and display name from your sign-in provider (Google, Apple, Microsoft, email/password, or phone). No food data is shared with Firebase.

Data export and deletion

You can download a complete copy of your data (food entries, water logs, settings, favorites) as JSON from the Settings page at any time. You can also permanently delete your account and all associated data from the Settings page; this action is irreversible.

AI disclaimer

Nutritional estimates produced by LibreNomNom are AI-generated and approximate. They are not medical or dietary advice. Actual values vary. Consult a healthcare professional for dietary guidance, especially if you have health conditions or restrictions.

Account removal

Use Settings → Delete account, or ask the deployment owner. They can delete your blob partition. Local browser data clears with the usual "Clear browsing data" flow.
