# Can I subscribe to a Google, iCloud or Nextcloud calendar?

Yes. Click the globe at the top of the [calendar](https://privacynotes.app/help/calendar), paste the calendar's address and click Subscribe. Your calendar app gives you the address: in Google Calendar it is "Secret address in iCal format", in iCloud you share the calendar as a Public Calendar, and in Nextcloud you copy its subscription link.

The events show in your calendar with a globe. Each device checks for changes when the app opens, then every hour while it is open. A moved or cancelled meeting updates here too. Subscribed events are read-only and have no reminders. To change one, change it in the calendar it comes from. They are not saved as notes, so they take no storage and are not in search or backups. If you want copies you can edit, use Import instead.

To stop a subscription, click Remove in the same window. Its events disappear from all your devices. You can subscribe to up to 20 calendars, and it is free. Your calendar address is kept in your encrypted settings. In the web app, our server downloads the calendar for you and keeps nothing.
