Frequently asked questions
Is there really no subscription?
Pro is a one-time purchase. Because everything runs on your Mac, there is no server for us to keep paying for — so there is no reason to charge you every month. The optional yearly plan only exists as a cheaper way to get started.
Do I need to create an account?
No. CalendarVault has no login and no account on our servers. Your licence key is verified offline, right on your Mac.
Does my calendar data leave my computer?
No. The app talks directly from your Mac to Google, Microsoft and iCloud using your own permissions. We never see your events.
Can I use my licence on more than one Mac?
Yes. One purchase covers all of your machines — there is no device lock.
What do I get during the beta?
The full app, free, while we finish building it. The launch prices above apply once we ship.
What about refunds?
Fair-use refunds within 14 days, no questions asked.
