Hetk keeps your calendars in sync across Google Calendar™, Microsoft Outlook™ and Apple iCloud™. Connect your accounts, pick which calendars to pair, and Hetk copies events between them. Create an event in one calendar, and it appears in the others within seconds. Edit or delete the original, and its copies follow. iCloud™ changes arrive within a few minutes.

Built for more than one calendar that matters
Freelancers and consultants with a calendar per client. People who keep work and personal apart. Teams split across Google Workspace™ and Microsoft 365™. If you have ever been double-booked because a meeting lived in a calendar you forgot to open, Hetk is for you.

Privacy you choose, per sync pair
* Replace the details with "Busy": the copy keeps the time, and its title becomes "Busy". Its description and location are removed.
* Flag the copy as private in the target calendar.
* Attendees never travel with a copy, so syncing never sends an invitation or shows who a meeting is with.
* Title templates let you label copies by where they came from, for example [Client A].

You stay in control
* Choose one-way or two-way sync for each pair, not for the whole account.
* Unlimited calendars on every plan. Plans differ only in the number of sync pairs.
* Hetk uses the official Google Calendar API™, Microsoft Graph™ and Apple™ CalDAV. Google™ and Microsoft™ connect through their own sign-in pages, so Hetk never sees those passwords. iCloud™ uses an app-specific password that you can revoke at any time.
* No AI. The sync engine is deterministic software.

Pricing
* Personal: $15 a year or $2 a month, up to 3 sync pairs.
* Professional: $50 a year or $6 a month, up to 8 sync pairs.

Every plan includes real-time sync, privacy controls, and Google™, Outlook™ and iCloud™ support.
