The problem
You have a work calendar (Google or Outlook) and a personal calendar on a different provider. When someone books a meeting during your dentist appointment or your kid’s school play, you only find out when it’s too late.
Manually copying events between calendars is tedious and easy to forget. Sharing your personal calendar with your employer isn’t an option, you don’t want your manager seeing “Therapy appointment” or “Job interview prep.”
A day in the life: The visibility nightmare
It’s Wednesday, and your manager is looking for a time to meet with you about your upcoming promotion. She sends a Slack message: “Quick 30-min sync tomorrow (Thursday) at 3 PM?” You check your work calendar (Outlook), totally clear. You say yes.
Thursday at 2:55 PM, you get a reminder notification on your personal iPhone calendar: “Therapist appointment in 5 minutes.” You blocked it on your personal Google Calendar weeks ago, but your work calendar has no idea. Now you’re about to tell your manager you need to reschedule your promotion conversation because you have a personal appointment. It looks unprofessional, and your manager is visibly annoyed.
Even worse, your manager noticed the calendar invite you sent (confirming the 3 PM meeting) showed your work email, but you’ve been vague about why you suddenly need to reschedule. She’s now wondering if you’re actually available to take on the promotion, or if you have other issues going on.
The same thing happens with your dentist appointment last month, your son’s baseball game next week, and the job interview you’re considering (which is blocked on your personal calendar). Every time, your work calendar shows you as free, so your coworkers schedule over your personal life. Every time, you either skip something important or look flaky by rescheduling last-minute.
Worse: what if you accidentally share your entire personal calendar with a coworker? They’d see all of this, therapist appointments, medical procedures, personal job interviews, family events. That’s way too much information about your private life. But without sync, your only option is to manually maintain two separate calendars and hope they don’t overlap.
How Hetk solves this
Set up a one-way sync from your personal calendar to your work calendar with Mark as Private enabled. Hetk copies your personal events as “Busy” blocks, your coworkers see that you’re unavailable, but the event title, description, and attendees are hidden.
Typical setup
| Setting | Value |
|---|---|
| Source | Personal calendar (Google, Outlook, or iCloud) |
| Target | Work calendar |
| Direction | One-way (personal → work) |
| Privacy | Mark as Private, title replaced with “Busy” |
| Show As | Busy |
What your coworkers see
- A blocked time slot marked “Busy”
- No event title, description, location, or attendees
- Your free/busy status is accurate for scheduling
What stays private
- Original event title and description
- Location, attendees, and meeting links
- Which personal calendar the event came from
Why not just use Google’s “other calendars” feature?
Google lets you view other Google calendars, but it doesn’t work across providers. If your work is on Outlook and your personal calendar is on Google (or iCloud), native tools can’t help. Hetk syncs across Google, Outlook, and iCloud, any combination.
Events also sync in real time. When you add a personal event, it appears as a busy block on your work calendar within seconds.
Detailed setup walkthrough
Syncing work and personal calendars while preserving privacy is simple:
Connect your work calendar to Hetk, Log in with your work email account (Google Workspace or Microsoft 365).
Add your personal calendar, Log in with your personal account (Google, Outlook, or iCloud). This is where you keep dentist appointments, family events, and personal commitments.
Create a one-way sync from Personal → Work with “Mark as Private”, This is the key step. Your personal events flow to your work calendar, blocking time as “Busy”, but the event titles and details are completely stripped. Your coworkers see unavailable time slots; they don’t see reasons.
Choose your privacy level, You can also set “Show As: Busy” (standard) or “Show As: Out of Office” (for longer blocks like vacations). This gives coworkers additional context without exposing details.
Optional: Set up reverse sync, Some people also want their work calendar visible on their personal calendar, so they see both sides in one place. Add a one-way sync from Work → Personal if you want that unified view on your personal device.
Test it, Add a personal event called “Test Private Event” to your personal calendar. Within seconds, it appears on your work calendar as “Busy” with no title visible.
Within minutes, every personal commitment automatically blocks your work calendar. Coworkers still see you’re unavailable; they just don’t see why. Your therapist appointment becomes “Busy” at 3 PM. Your son’s baseball game blocks your calendar Thursday evening. Your dentist appointment shows as unavailable. All the details stay private.
Privacy considerations specific to work/personal boundaries
The “Mark as Private” feature is specifically designed for the work/personal boundary:
- Title is replaced with “Busy”, The original event title is never visible on the work calendar. “Therapy appointment” becomes a blank “Busy” block.
- Description, location, attendees removed, All content is stripped. Only the time block remains.
- No healthcare data leakage, Medical appointments, mental health sessions, and personal procedures show only as time blocks. Your employer has zero visibility into your health information.
- Family time protected, “Kids’ soccer practice” or “Parent-teacher conference” shows as unavailable; coworkers don’t see details about your family.
- Personal life confidential, Job interviews, financial meetings, legal appointments, all protected. Just “Busy” blocks on your work calendar.
This is why Hetk’s “Mark as Private” is more secure than just sharing your personal calendar with a blanket permission. Sharing means someone could view the full calendar and see everything. Syncing with privacy controls means the information is transformed before it ever reaches the work calendar.
Frequently asked questions
Q: What exactly gets stripped when I enable “Mark as Private”?
A: Four pieces of data are removed: the event title, description, location, and attendee list. Only the date, time, and your busy/free status remain. So “Dentist appointment at Smith Dental, 123 Main St, discussing wisdom teeth removal” becomes simply “Busy 3-4 PM” with no other details visible on your work calendar. This is the most aggressive privacy setting and is appropriate for most personal events.
Q: Can my work calendar still show me as “unavailable” if I mark it as private?
A: Yes. In fact, that’s the whole point. “Busy” blocks prevent coworkers from scheduling over your time while revealing zero details. You can also choose “Out of Office” if you want to give slightly more context (e.g., for vacation days) without exposing what you’re actually doing. All options protect your privacy while keeping your work schedule accurate.
Q: What if I don’t want all personal events showing on my work calendar, only certain ones?
A: You have complete control. You can manually mark individual events as private before they sync, or you can use Hetk’s sync settings to apply “Mark as Private” only to specific event types (if your calendar provider supports categories like “Personal”, “Medical”, “Family”). Hetk respects your calendar’s existing structure, so if you’ve categorized events, you can be selective about what syncs.
