Support

Use the form below to reach us.

The form has no email address field. If you want a reply, put a contact address in the message yourself — it is optional. We use what you send only to answer you and to improve the app.

What we cannot do

If you forget your PIN, nobody — including us — can open your vault. This is a limit of the design, not a support issue. The key is derived from your PIN, and we do not hold it.

We also cannot retrieve the photos or videos you stored. They exist only in encrypted form, and we cannot decrypt them.

Cancelling a subscription

Cancel in the Settings app on your iPhone → your name → Subscriptions. We cannot cancel on your behalf. The app shows you how to get there from its lock screen, even when the vault cannot be opened.

Contact form

If you are reporting a bug, please include your iPhone model and iOS version and the exact steps that led to it — that is what lets us reproduce and fix it.

The form is in Japanese, but you are welcome to write in English.

If the form does not appear, open it here instead.
