Visibility levels
For each sync you decide how much the receiving side sees of your events. This is the heart of the privacy concept: you share availability, not necessarily content.
The three levels
Section titled “The three levels”| Level | What arrives in the target | Typical use |
|---|---|---|
| Busy only (default) | Just the time slot, titled “Geblockt” by default — or your own placeholder text like “Busy” | Personal events block the work calendar — maximum privacy |
| Title + time | Event name plus start and end time | Linking your own calendars, close team coordination |
| Full details | Incl. location, description, notes and links, including the join link of Meet, Teams or Zoom | Assistants, shared schedule management |
With a two-way sync, you can pick the level per direction.
Meeting links
Section titled “Meeting links”With Full details, the join link of a video call comes along, even when the source only stores it as a button (e.g. Google Meet on bookings):
| Target calendar | Where the link goes |
|---|---|
| As its own join button on the event | |
| Outlook | Into the location if that is empty, otherwise below the description |
| Apple, GMX, WEB.DE and other CalDAV calendars | As with Outlook, plus the event’s conference field |
If the description already contains the link, it is not added twice. Dial-in numbers and PINs are never transferred. With “Title + time” and “Busy only” the link stays out.
Out of office, tentative, working elsewhere
Section titled “Out of office, tentative, working elsewhere”Events marked as out of office, tentative or working elsewhere in the source (Outlook “Show as”, Google “Out of office”) keep that status:
- In an Outlook calendar exactly as in the source.
- In a Google calendar as a busy event. Google only allows real out-of-office events in the primary calendar of a work account, and not as all-day events.
- In CalDAV calendars as a marker that Outlook and Exchange read; whether Apple and others show it depends on the app.
For your own syncs this applies at every level. For sharings with others only from “Title + time” up, because “out of office” reveals more than “busy”.
What is never transferred
Section titled “What is never transferred”Regardless of the level, these stay out:
- Attendee lists and their email addresses — that’s third-party data
- Organisers and accept/decline status
- Attachments

Setting and changing
Section titled “Setting and changing”You pick the level when setting up the sync, in the “Visibility” step — and you can change it any time later via the sharing’s three-dot menu → “Edit”. All synced copies in the target are rewritten automatically → Edit a sharing.
Which level for which case?
Section titled “Which level for which case?”- When in doubt: “Busy only”. It serves the main purpose — no double bookings — without revealing anything. You can always upgrade later.
- “Title + time” when the other side should know what blocks you (e.g. your own two calendars, or a close team).
- “Full details” only when the receiving side needs to work with your events (assistant, co-founder).
