Sky Calendar for iPhone

Questions, a bug, or an event that looks wrong? Write to skycalendarapp@proton.me. Please include your iPhone model, iOS version and the city you had selected. We usually answer within two working days.

Reminders

I don't get reminders

Check that notifications are allowed for Sky Calendar in iOS Settings → Notifications, and that the event group is not hidden in the app. Focus modes and Low Power Mode can also hold notifications back.

A reminder came at the wrong time

Reminders use the local time of the city they belong to. If you follow a city in another time zone, the time shown in the reminder is that city's local time.

Sky Calendar Plus

Restore a purchase on a new device

Open the Plus screen in the app and tap Restore purchases, signed in with the same Apple ID you bought Plus with.

Cancel or change a subscription

Go to iOS Settings → your name → Subscriptions → Sky Calendar. Cancel at least 24 hours before the period ends to avoid the next renewal. Plus stays active until the end of the period you paid for.

Refunds

Full details are in the Terms of Use.

Offline mode

Turn on Offline mode in Profile to save, for your cities, the precomputed events, eclipse paths and observing sites (about 1 MB per city). Live data such as aurora alerts, cloud forecasts, ISS passes and comets needs an internet connection.

Accuracy and safety

Event times are calculated from public astronomical data. Weather, aurora and visibility forecasts are estimates and can be wrong. Never look at the Sun without certified solar eclipse glasses or a proper solar filter.

Delete your account

In the app, open Profile → Delete account. Your profile, cities, reminder settings, devices and purchase records are deleted at once. Deleting your account does not cancel an App Store subscription; cancel it in iOS Settings as described above. If you can't open the app, email us from the address you used and we will delete the account for you.

Privacy

The app has no ads, analytics or tracking. See the Privacy Policy.
