Food Exposure Logger

Pending Exposures 0

Awaiting event association

Pending foods do not enter recurring ingredient analysis unless you deliberately associate them with a symptom or event.

Log Food Exposure

Manual entry

Record Symptom / Event

Record what happened and tick the food exposures that may have preceded it. Only selected exposures contribute to recurring ingredient analysis.

Investigative clue only — not medical proof: This view counts how many distinct events each ingredient has been associated with. Repetition highlights exposures worth discussing or investigating further; it never proves causation.

Unverified Whole-Food Entries

Logged without ingredient lists

Manual foods logged without an ingredient list are tracked separately here so their product names are not conflated with verified ingredients.

Backup & Data Portability

All data resides solely in your browser's local IndexedDB database. Export regular backups to protect against phone loss or browser resets.

Encrypted Backup (AES-256-GCM)

Encrypts your backup using Web Crypto API (PBKDF2-HMAC-SHA256 with 210,000 iterations + AES-256-GCM) before saving the file.

Restore / Import Backup

Select backup file (.json)

Passphrase (only if backup is encrypted)

Security & Storage Architecture

Local-first isolation: No server, cloud database, accounts, telemetry, or analytics exist in this app.
IndexedDB vs Encryption: IndexedDB stores data locally on your device. It is protected by your phone's operating system passcode and hardware disk encryption (iOS Data Protection / Android File-Based Encryption), not independent database encryption. Use the AES-256-GCM Encrypted Backup option above when storing backups externally.
Barcode lookup privacy: Scanning a barcode transmits only the numeric barcode to the public Open Food Facts API (`world.openfoodfacts.org`). Your food history, timestamps, and symptoms are never transmitted.
Cached lookups: Retrieved products are cached locally (0 cached) to prevent duplicate network requests.

Danger Zone

Permanently erase all food exposures, events, associations, and cached products from this device.
