3. What Data We Collect
3.1 Device Identifier
When you first launch the App, a randomly generated device identifier (format: “device_[timestamp]_[random]”) is created and stored locally on your device. This identifier is used to:

- Optional free-text entries for “Other” selections
This data is stored in our backend database (Supabase, EU servers) linked to your device identifier.
3.3 Usage Data
