Heivol Calendar
A private personal calendar that lives on Heivol infrastructure. Login with Heivol Identity, plug it into Heivol Assistant as a first-class skill, and let your agent read your week and book on your behalf. Free for everyone with a Heivol account.
What it does
Login with Heivol Identity
Same SSO that signs you into the rest of Heivol. No new account, no extra password, no third-party calendar provider holding your data hostage.
First-class assistant skill
Heivol Assistant gets the calendar skill installed automatically. Ask your assistant what's on next week, ask it to find a free 30-minute slot, ask it to move a meeting — it reads and writes against the same calendar you see in the web UI.
Ownership by JWT subject
Every event is owned by your Heivol Identity subject. Tokens minted for your agent inherit the same subject, so you and your assistant always see the same calendar — no siloed view, no cross-tenant leakage.
Web client at a clean URL
calendar.heivol.com — same theme cookie as
the rest of .heivol.com, light/dark in sync with
the assistant and the rest of the suite.
Locally hosted in Denmark
Same stack as the rest of Heivol — runs on Heivol's own hardware, in Denmark, under Danish/EU jurisdiction. No hyperscaler, no US cloud, no third-party calendar vendor.
Free with your account
No subscription, no per-seat charge, no premium tier. Heivol Calendar is included with every Heivol Identity account. The only thing you pay for is the dedicated VM if you also run Heivol Assistant.
