When you sign in with Google, we store your email address and display name. All other information is provided by you voluntarily — text you type, documents you upload, and profile text you paste.
The text you provide is sent to an AI model (xAI Grok) to generate guesses about your interests. Your confirmed and rejected guesses are stored in your profile and re-used on future visits to make guesses more accurate. This is prompt-based personalization — no model is fine-tuned.
All data is stored in a Postgres database with row-level security. No user can access another user's data.
You can permanently delete all of your data at any time from the Settings page. This removes all your inputs, guesses, feedback, profile data, and account information. The deletion is immediate and irreversible.
