Why settings won’t fix Google Calendar. Cross-device sync and smart suggestions exist because Google can read your events. There is no setting that keeps the convenience while hiding the contents, because the readable copy on the server is what makes the features work. Privacy here means a calendar that is encrypted before it syncs.
What actually matters in a calendar. End-to-end encryption of event details, an open standard like CalDAV so it works with the apps you already use, clean sharing and invitations, and reliable reminders across your devices. Open standards are the quiet win: they keep your data portable and your phone’s native calendar app working.
How to switch. Export your current calendar as an ICS file and import it, then connect the new account over CalDAV on your phone and laptop so everything stays in sync. Run the old and new calendars together for a couple of weeks to catch any recurring events that did not transfer cleanly before you switch off Google.
Frequently asked
- Can I import my existing events?
- Yes. Export your Google Calendar as an ICS file and import it into the new calendar. Recurring events and reminders carry over, though you may want to double-check anything with an unusual repeat rule.
- Will it sync to my phone's calendar app?
- Most of these use CalDAV, the open calendar standard, so they sync with the built-in calendar on iPhone, Android, and desktop. You are not stuck inside one company's app.
- Can I still invite people who do not use it?
- Yes. Invitations go out as standard calendar messages that any calendar can read and respond to, so the people you schedule with never need to switch anything.
