Last updated
Proton Calendar is encrypted cloud with phone viewing. Events, calendars, and invites live in your Proton account. The phone caches upcoming months for offline checks.
Same Proton ID means same calendars. Shared calendars need the same invite accepted on the new phone. Exact cache names shift with releases. For moves, sign in and let the calendar download fully before adding events. Duplicate calendars usually trace to a second Proton address. Screenshots of settings help when support asks for reproduction steps later.

Frequently asked questions
How do I move Proton Calendar to a new phone?
Sign in on the new phone with the same Proton login and calendars return from the encrypted cloud. Phone holds login and event cache only. Imported ICS files merge server side. Verify the calendar name before wiping, since a second ID shows empty.
Does Proton Calendar work offline?
Yes, in Proton cloud with end to end encryption. The phone holds a working copy plus cache for offline viewing. Edits merge on sync. Export ICS files from the web for archiving, since the phone never holds the master copy alone.
