Your journal stays on your Mac.
Daily Flow stores journal entries as ordinary Markdown files in the folder you choose. Journal text, habits, Flows and perspectives are not uploaded to PX7 Digital.
If you grant calendar access, Daily Flow reads events through Apple EventKit so it can display them in the app. It does not upload or sell calendar data.
License activation sends the license key, app identifier and a one-way device identifier to the PX7 license service. Update checks request the public update manifest. Purchases are processed by Stripe under its own privacy policy.
