Folio privacy policy

Last updated: 28 September 2026

Folio ("the app") is a daily puzzle game made by Backslash. This policy explains what the app collects, why, and your choices.

What we collect

Your puzzle progress. Which puzzles you've solved, your times, your quest progress, your hints and the challenges you've sent or received. This is saved on your phone and backed up to our cloud database (Google Firebase) so it isn't lost and can move to a new phone.

An account ID. When you first open Folio, it signs you in anonymously with Firebase Authentication. This gives your backup an ID but doesn't identify you personally.

Google account details (optional). If you choose "Sign in with Google", we receive your name and email address from Google to link your backup to your Google account. We use them only for signing you in.

Your display name (optional). The name you choose appears next to your time on a challenge's scoreboard, which only people with that challenge's code can see.

Crash reports. If Folio crashes or something goes wrong (a failed sign-in, a backup that didn't save), the app sends a report to Firebase Crashlytics: what went wrong and where in the app, your device model and Android version, the app version, and your Folio account ID so we can match reports to a backup. Reports don't include your name or email. We use them only to find and fix bugs.

Advertising data. Folio shows ads through Google AdMob. AdMob may collect your device's advertising ID, IP address and information about how you interact with ads, to show and measure ads. Where the law requires it, Folio asks for your consent first. You can change that choice at any time in Settings → Ad privacy. See how Google uses information from apps that use its services.

What we don't do

We don't sell your personal information. We don't collect your contacts, location, photos or files. There's no chat. Your progress is used only to run the app.

Where your data is kept

With Google Firebase (Cloud Firestore, Firebase Authentication and Firebase Crashlytics), and with Google AdMob for ads. Data is encrypted in transit.

Keeping your data

Your backup is kept for as long as you have an account. Uninstalling the app removes the copy on your phone, but not the backup. Crash reports are kept by Crashlytics for 90 days, then deleted.

Deleting your account and data

In the app: Settings → Delete account and data, then confirm. This immediately deletes your cloud backup, your times and display name on challenge scoreboards, your Folio account (and its link to Google, if you signed in), and everything Folio saved on the phone.

Without the app: email the address below from the Google account you signed in with (or tell us roughly when you last played, if you never signed in) and ask us to delete your Folio account. We'll delete it and all of the data above within 30 days and reply to confirm.

Children

Folio is not directed at children under 13, and we don't knowingly collect information from them.

Changes

If this policy changes, we'll update the date above.
