Questions answered.
Do I need an account?
No. Download it and start. Full access from the first minute; the subscription lives in the App Store or Play Store when you decide to keep it.
Does it work offline?
Partly. Your memories are on the phone, so saving, searching and reading them works offline. Asking GrantAi to write an answer needs a connection, because the answer is composed by Google Gemini.
Where is my data stored?
Your memories are stored on your device in an encrypted database; we keep no copy. When you ask a question, that question and the memories it matched are sent through our relay to Google Gemini to write the answer, and are not stored by either of us. The Privacy Policy lists exactly what is sent.
