Getting Started with Hetk — A Testing Guide for Early Adopters

Thanks for being one of the first to try Hetk. This guide walks you through setting up and testing calendar sync so you can see how it works before committing your main calendars.

Start with secondary calendars

Both Google and Outlook let you create additional calendars. This is the safest way to test — your real events stay untouched.

Google Calendar: Click the + next to “Other calendars,” then Create new calendar. Name it something like “Hetk Test.”

Outlook: Right-click My calendars, then Add calendar → Create blank calendar. Name it “Hetk Test.”

You’ll sync between these test calendars first. Once you’re comfortable, you can switch to your real ones.

Connect your accounts

1. Go to app.hetk.io and sign in with your Google or Microsoft account
2. Connect your second account — if you signed in with Google, link your Microsoft account (or vice versa)
3. Select the test calendars you created from the calendar list

Create your first sync

Pick a source calendar and a target calendar, then choose a direction:

• One-way — events flow from source to target only
• Bidirectional — events flow both ways

You’ll also see a few settings:

For your first test, leave everything at defaults. You can experiment with these later.

What to test

Create a test event

Add an event to your source calendar with a recognizable title, like “Hetk Test — Team Meeting.” Give it a description and location too.

Within about 30 seconds, it should appear on your target calendar. Check that:

• The title, description, and location match
• Start and end times are correct
• All-day events stay as all-day events

Update and delete

• Change the event title or time on the source side — the change should sync within a minute
• Delete the event from the source — it should disappear from the target

Try privacy mode

Create a new sync (or edit your existing one) with Mark Private turned on. When you create a new event, the synced copy should show up as “Busy” with no description, location, or other details. This is useful when you want to block time on your work calendar without sharing personal event details.

Bidirectional sync

If you chose bidirectional, try creating events on both sides and verify they appear on the other calendar. Edits and deletes should work in both directions.

Good to know

Source wins in one-way sync. If you edit or delete a synced event on the target calendar, Hetk will automatically restore it from the source. The source calendar is always authoritative — manual changes to synced copies are overwritten.

Always edit the original event. In both one-way and bidirectional sync, edits to the original event propagate correctly to the synced copy. Editing the synced copy directly doesn’t work as expected — in one-way sync it gets overwritten, and in bidirectional sync the change won’t flow back to the original. If you need to change an event, edit it on the calendar where you created it.

Bidirectional sync creates events on both sides. When you use bidirectional sync, new events created on either calendar are synced to the other. Each side acts as a source for events that originate there.

Attendees are not copied. When an event syncs, the attendee list is intentionally left out. This prevents the destination calendar from sending duplicate invitations to people who are already invited on the original event.

Recurring events sync as individual occurrences. Each instance of a recurring event is synced independently, not as a recurring series.

Previously existing events don’t sync retroactively. Only events created or updated after the sync is set up will be synced.

Cleaning up

If you want to start fresh:

1. Delete the sync relationship in the Hetk dashboard
2. Delete any synced events manually, or just delete the test calendar entirely

Deleting a sync relationship stops future syncing but doesn’t remove events that were already synced. This is intentional — Hetk doesn’t delete events it didn’t create.

Something not working?

• Events aren’t showing up — check that both accounts show a green status in the dashboard, and give it up to 60 seconds
• Events show as “Busy” unexpectedly — check if Mark Private is enabled in your sync settings
• Duplicate events — make sure you don’t have overlapping one-way syncs in both directions. Use bidirectional sync instead
