Your prayer life is not a data source.

You do not need to sign up, log in, or create a profile to use Missal Page.

We do not collect personal data, advertising identifiers, or in-app analytics about your usage.

Missal Page does not show third-party advertising and does not embed ad SDKs.

Reminder preferences and similar app settings are stored on your device using Apple's standard frameworks.

Missal Page may connect to our backend service to download updated liturgical calendar data or missal page data when those resources improve. These requests are used to deliver the content itself, not to build a user profile.

If you choose to enable holy day reminders, scheduling happens through Apple's local notification system on your device. You can change this setting at any time inside the app or in iOS Settings.
