Why it exists
I built Calendarina for my wife, Arina. Our plans lived in three apps and one very long chat. I wanted one place for the two of us — then her parents joined, then friends asked for it.
Free while we build it with you.
Every feature is free for everyone who joins now. In return, tell us where it hurts — what’s missing, what’s confusing, what you’d happily pay for. Every message goes straight to the founder.

Questions
Before you sign in.
Does it sync with Google Calendar?
Not both ways yet. You can subscribe to any schedule you publish from Google or Apple Calendar, and it stays up to date there. Two-way sync is something we’re looking at — if you want it, tell us in the app.
Why sign in with Google?
So there’s no new password to remember. We get your name, email address and profile photo — nothing else. We never read your Google Calendar, your mail or your contacts.
Is it an app I have to install?
No. Calendarina runs in the browser on any phone or computer, so there’s nothing to download and nothing to update.
Can my mum use it without an account?
For a lot of it, yes. Anyone can open a schedule you publish or answer a time poll without signing up. To join a group and share a calendar, she’ll need to sign in with Google.
What happens to my data?
It’s used to run Calendarina and nothing else: no ads, no selling, no tracking across other sites. Other people see only what you choose to share. Read the privacy policy
Is it free?
Yes, everything, while we’re in early access. The first 200 accounts are founding members: when paid plans arrive, they get 12 months of any plan free, then 50% off for as long as they stay.
