Can I sync Apple iCloud with Google Calendar?

How does billing work?

Monthly or annual on both plans. You start with a 21-day free trial, no credit card required. When you subscribe, Stripe handles the payment. Annual saves up to 38% over monthly.

Can I cancel my subscription?

Yes, cancel anytime from the billing portal. Your subscription stays active until the end of the current billing period.

What happens to my data if I delete my account?

Deleting your account removes your account, connections, tokens and sync records at once. The few records listed in section 8 of our Privacy Policy are kept, and backups and logs expire within 90 days. Events already synced to your calendars stay there as regular calendar events.

Do you offer team plans?

No. Team plans do not exist yet. Hetk is for individuals.
