Thank you for using TimeTree. We’ve created new “Shared Calendar Guidelines” to explain in a simple and clear way how information shared in calendars is handled. These guidelines do not change how your information has been used so far.

• Shared Calendar Guidelines (Available only in English)

Background of the Update

• To make sure you can continue using shared calendars with confidence

• Ideally, this information should have been clearly stated from the beginning of the service; however, there were areas where explicit guidelines had not been provided until now

• To improve transparency as the service grows

• We kindly ask affected users to review the details and complete the necessary steps within the period below.

What to Expect Next

• 2026/04/23: Announcement (this notice)

• 2026/06/01 (planned): Agreement period starts

  • You will see a request to agree inside the app

  • You can skip the agreement during this period

• 2026/06/15 (planned): Agreement period ends

  • After this, skipping to the agreement will no longer be possible

Who does this apply to

• Users of shared calendars

• (Not applicable if you only use a calendar by yourself)

Important

• If you don’t respond during the agreement period, you may lose access to shared calendars

• If you do not agree, you will be removed from shared calendars and will not be able to use the feature

FAQ

Q. Will anything change? A. No. This is only an explanation—how your data is handled stays the same. Q. What if I don’t agree? A. You won’t be able to use shared calendars anymore. Q. Can I change my mind later? A. Yes. You can withdraw at any time, but you will need to leave all shared calendars. If you wish to withdraw only from a specific calendar, please leave that calendar.

We sincerely apologize for any inconvenience and appreciate your understanding and cooperation in reviewing and agreeing to the above. If you have any questions, please contact us via the inquiry form. Thank you for continuing to use TimeTree.
