History, retention, and how to think about your translation data

The Flutter history screen reads from local storage on your phone. The server processes each translation request but does not store source or translated text. Operators self-hosting VocatAI should document retention, backups, and deletion because those policies are deployment-specific.

Guest vs registered accounts

Keeping guest traffic out of the primary users table reduces accidental mixing in analytics and makes it easier to apply aggressive abuse controls without touching paid cohorts. Both guest and signed-in users get the same on-device history behavior.

What users should see

In-product copy should warn when cloud processing is required, surface download sizes for offline assets, and separate optional analytics from core translation. Those principles mirror the settings layout in the app today.
