Automatic Sync

Events sync in real-time between any two Google or Microsoft Outlook calendars. No manual copying, no missed meetings — seamless, instant synchronization.

Personal  ·  Dentist 9:00 AM → Work  ·  Busy 9:00 AM

Working Hours

Set boundaries between work and life. Events outside your hours stay where they belong. Your 6 AM workout won't block your coworkers' afternoons.

6:00 AM  ·  Workout → Skipped (outside 9 AM – 5 PM)

Time Rounding

Round synced event times to the nearest 15 or 30 minutes so back-to-back meetings don't overlap on your other calendar.

9:22 AM – 10:37 AM → 9:15 AM – 10:45 AM

Time Buffer

Add extra time before or after synced events automatically. Give yourself breathing room between meetings without manually blocking time on your calendar.

12:30 PM – 1:30 PM → 12:15 PM – 1:45 PM

Privacy first

Your details stay yours.

Choose to show when you're busy without revealing specific event details. Your calendar syncs keep your privacy intact while preventing double bookings.

Testimonials

When they wish you weren't so organized.

“I don't understand why you need to sync your calendars. I mean, shouldn't your work life be your life? That's what I do. Work is life, life is work. Why are you so organized?”

“So, you're using this tool to manage your calendar better? Tell me how taking your dog to the vet is more important than the Runway magazine redesign meeting at noon.”

“I tried to check when you'd be available, but your calendar was synced and blocked out for some nonsense called yoga in the park. There should be a day for doing nothing.”

“Yeah, if you could go ahead and stop using Don't Double Book Me to avoid those weekend shifts, that would be great. We need those TPS reports done, even on Saturdays.”

Frequently asked questions

Can't find the answer you're looking for? Reach out.

How does Don't Double Book Me work? +
Don't Double Book Me connects your two Google or Microsoft Outlook calendars and automatically syncs events where your availability is set to Busy, based on your preferences. You can control event visibility, decide whether to include all-day events, set specific working hours, and choose how event times are rounded.
Does Don't Double Book Me store any of my calendar events? +
No, we do not store any of your calendar details on our servers. Events are synced directly between your calendars. You can revoke our access at any time from Google or Microsoft directly.
Is Don't Double Book Me secure? +

Yes. We protect your email, access token, refresh token, and account identifiers with AES-GCM encryption, ensuring all data is encrypted both in transit and at rest.

Use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Can I control the visibility of synced events? +
Absolutely. You can customize how events from one calendar appear in the other — such as marking them as busy without revealing specific details, ensuring your privacy is maintained.
Can I cancel my subscription at any time? +
Yes. If you cancel, you can either use the service until the end of your current billing period or opt for a prorated refund.
Do you support Apple or other calendar services? +
Currently we support Google and Microsoft Outlook. We're working on expanding to other platforms — let us know if you're interested.
