FAQ

Do you need access to my calendar?

Yes, but scopes are minimal. We only read/insert events you approve. You can revoke access anytime in settings.

How do you handle energy without a wearable?

You can set a simple morning/afternoon/evening curve. Optionally connect services later for automatic insights.

Will rescheduling break my streaks?

No. Moving a habit inside the valid window keeps progress intact. We track intent and completion fairly.

Is there an iOS/Android app?

Mobile apps are planned. The web app already works great on phones.

How do I delete my data?

You can export and delete all data from the Privacy section. Disconnecting calendars is one click.
