How can we help?

Pick a place on the map, then add photos and text to create a capsule. Once you finish writing and seal it, the capsule is saved at that place.

You can write one at your current location or at a place you've visited on the map. Your location must be verified before you can seal a capsule.

A capsule with no lock can be opened as soon as it's sealed. A locked capsule opens once the date or condition you set is met.

You can edit it freely before sealing. Once sealed, the content can't be changed, but you can delete it from the capsule detail screen.

Yes — invite friends while creating a capsule to make a friend capsule that everyone can write in together. Invited friends can join once they accept.

Everyone can add or edit entries until the host seals the capsule. Once the host seals it, the content can no longer be changed.

Capsules set to public can be seen by other users on the map and in the archive. Private capsules can only be seen by you and its participants.

Yes, you can choose public or private while writing. A private capsule only shows its location on the map — its content is visible only to you and its participants.

Turn on the lock in the writing screen and set the date it should open. The capsule can't be opened before that date.

It unlocks automatically and becomes viewable once the date you set while writing it arrives.

An unlocked capsule opens as soon as it's sealed; a locked one opens once its set date has passed. A friend capsule is complete once every participant has written an entry and the host has sealed it.

Places are selected based on public data such as tourist attractions and landmarks. You can write capsules centered around these places.

When you seal a capsule, your location is automatically verified if you're near that place. You need to allow location permission to verify.

Verification may fail if location permission is off or GPS signal is weak. Please allow location permission in settings and try again outdoors.

It's a record that collects the places where you've left capsules. As you visit more places, your archive fills up along with it.

In the Archive tab, you can see the list and count of places where you've written capsules so far.

You can change your nickname and profile image anytime from the account screen.

Go to Account > Settings to check and change notification permission. If you've already denied it, you'll need to allow it directly in your device settings.

Reach out through Account > Support > "Send feedback to the developer," and we'll get back to you after checking.

You can do this from the Delete Account menu at the bottom of Account > Settings. Capsules and records can't be recovered once deleted.
