Parish data
Updates never happen on their own. Pressing the button downloads one public file; your location and your picked parishes are not sent.
Help keep it right
Is a schedule wrong or missing? Write the correct details below, following the example, then tap Send correction text. Your email app opens with it ready to send. The app itself sends nothing.
Search the Library first: if the parish is there, tap Send a correction on that parish instead, so it is matched exactly.
Tip: you can attach a photo of the schedule in your email app.
About, privacy and credits
Your privacy
Your location and your Favorites stay on this phone. No accounts, no analytics, no ads, no tracking.
The app goes online only when you press Check for updates. A parish’s website, phone, email or Directions, Share and Support open other apps or pages, which follow their own privacy rules.
A correction you email goes from your own email app, so the publisher sees your address and what you write.
Accuracy
Schedules change. Please confirm with the parish before travelling. When a source gives no time, or no start or end time, the app says so.
