You were never
meant to see this.

A mystery game played inside someone else's phone. The truth is in what they thought they deleted.

Every story here is fiction.

The guilt you feel reading someone else's phone probably is not.

The evidence hides in ordinary habits.

Nothing glows. Nothing points. Dates, histories, deleted items. The answer sits where it would sit on anyone's phone.

The fact that it was deleted

Behind the inbox is a Recently Deleted tab. When something was removed matters more than what it said.

Dates do not lie

Three weeks running, only Tuesday is empty.

Every app actually works

Messages, photos, maps, notes, music, browser history. The locked album and the private tabs are exactly where you would expect them.

One question at a time.

The person who asked for your help asks you directly. Every answer brings the next question, and the story gets a little uglier each time.

Answers are free text, so phrasing does not have to match. Stuck? There are up to three hints.

15 cases. All of them someone's life.

A partner, a mother, a best friend, a grandmother. The closer the tie, the heavier the find.

Questions people ask

Is this a real person's phone?
No. Every character, message, photo, and record is written for the game. The app never accesses a real device or account.
What languages can I play in?
Japanese and Traditional Chinese. There is no English version of the game yet, so this page is the English one for now.
How long is a case?
Roughly 50 to 60 minutes. Progress is saved, so you can put a case down and come back to it.
Can I play offline?
No. Stories are served from our content server, so the game needs a connection. Nothing about the story ships inside the app.
Do I need an account?
No. We never ask for your name or email address. The privacy policy explains what is stored instead.
When does it launch?
Both the iOS and Android builds are in preparation. The buttons at the top of this page will become download links on release day.
