Your account email, your plans and tasks, your brain-dumps (including saved ones and held thoughts, with any mood tag you chose), your energy pattern, notes you keep about people and conversations, and — if you connect them — push-notification subscriptions and Google Calendar tokens. It lives in our database (Neon, Postgres) and is used only to run the app for you.
When you tap "Make it a plan" (or ask for re-planning), the text of that dump and your task titles are sent to Google's Gemini API to shape the steps.
When you log a conversation with someone, that note is also sent to Gemini — to suggest a few topics, a next-time prompt, and (if you mention another person you track by name) a possible connection between them, which stays unconfirmed until you approve it. This is on by default; turn it off per-account any time in Settings and no further notes are sent. Nothing about people is ever used for anything but showing it back to you — no training, no ads, no sharing.
No ads, no selling data, no analytics trackers, no reading your calendar events (only busy times), no streaks watching you. Payment details go to Stripe; we never see card numbers.
Delete any task, thought, note, or person whenever you like. Settings lets you download your data or delete your entire account — deletion is immediate and unrecoverable, and removes everything above.
Mindplan is a small product; write to the address on the account you signed up with and a human will answer.
