On iPhone, before any AI feature is used for the first time, 1krNote asks Use AI features? It lists what is sent to Google Gemini, the AI service behind the features:
- The text of your notes, to build the search index
- Your voice during an AI call
- Camera pictures, only when you turn the camera on in a call
Nothing is sent until you tap I agree. With Not now, the app keeps working without AI: notes, reminders and the calendar are unaffected.
"Allow AI processing first (start an AI call to see the details).": you chose not now earlier. Open the AI tab and start a voice chat; the consent screen appears again, and you can agree there.
On Android, what the AI sends is explained in the privacy policy (Settings → Privacy policy).
