Privacy Policy
Last updated 6 October 2026
GameDen is a single app containing hundreds of small games. It has no accounts, no sign-up and no login, and it never asks for your name, address, phone number or date of birth. Every game runs entirely on your device.
This policy describes exactly what does leave your device, why, and how to stop it. It was written from the app's own source code rather than from a template.
What stays on your device
- Every game, including all its levels, puzzles, art and music. Nothing is downloaded to play.
- Your scores, streaks, progress, saved games, favourites and settings. These live in the app's own storage and are removed when you delete the app.
- Your Pro status, which is held by Apple's App Store, not by us.
Face data (Blink Dash)
What is collected. One game, Blink Dash, lets you steer by pulling faces at the front camera instead of tapping. On iPhones with a TrueDepth camera it uses Apple's ARKit face tracking. While you play in face mode, the game reads seven facial expression values from ARKit for each camera frame: left eye blink, right eye blink, raised eyebrows, left smile, right smile and how far your mouth is open. Each value is a single number between 0 and 1. The game does not read, capture or keep camera images, video, depth maps, the 3D face mesh, or any other face geometry, and it does not identify or recognise who you are.
How it is used. The values are used only in that moment to control the game (for example, a blink makes your character jump) and are discarded as soon as the frame has been processed. They are never used for advertising, analytics, profiling or any other purpose.
What is stored, and where. If you choose to calibrate face controls, the game saves your preferred sensitivity for each expression: two threshold numbers per expression, such as "a blink counts above 0.55". These settings are stored only in the app's own storage on your device. No expression values, images or face data are stored anywhere else.
Sharing. Face data is never sent off your device. It is not shared with us, with Google Firebase, Google AdMob, Apple Game Center or any other third party. Analytics events for Blink Dash only record whether you played in face mode or touch mode, never any face data.
Retention and deletion. Expression values are not retained at all. Your calibration settings stay on your device until you reset them in Blink Dash's face settings or delete the app, which removes them completely. Face mode is optional: you can play Blink Dash with touch controls, and you can turn off camera access at any time in Settings > GameDen.
Your own photos. Blink Dash and Den Raiders also let you put a face from a photo you choose onto a game character. The app uses Apple's on-device Vision framework only to find where the face is in that photo so it can crop it. The cropped picture is saved in the app's own storage on your device, is never uploaded or shared, and is deleted when you remove it in the game or delete the app. This does not use the TrueDepth camera.
What leaves your device
| What | Who receives it | Why |
|---|---|---|
| Anonymous usage events — which game was opened, how long a visit lasted, scores, and whether an ad or purchase screen was shown. Attached to a random per-install identifier, never to you. | Google Firebase Analytics | To see which games are played and which are ignored, so the app can be improved. |
| Advertising requests, including the device identifiers your consent choices allow. | Google AdMob | Ads pay for the app being free. GameDen Pro removes them completely. |
| Leaderboard scores and achievements, under your Game Center nickname. | Apple Game Center | Optional ranking against other players. Controlled by your Apple Account settings. |
| Feedback you choose to send — your rating, category and message, plus the app version, build, device model and iOS version, and your email address only if you type one so we can reply. | Google Firebase (Firestore), then Resend | So a bug report can be understood and answered. Sent only when you tap Send. The message is stored in Firestore and forwarded to our inbox by e-mail through Resend. |
| A push notification token, if you allow notifications. | Google Firebase Cloud Messaging | To send occasional reminders. Declining notifications means no token is registered. |
| Purchases — handled entirely by Apple. We never see your payment details. | Apple | To sell and restore GameDen Pro and tips. |
Tracking and your choices
On first launch GameDen asks two things: Apple's App Tracking Transparency prompt, and — if you are in the UK or EEA — Google's consent form for personalised advertising. Whatever you choose is respected, and you can change your mind at any time:
- Tracking: iOS Settings → Privacy & Security → Tracking.
- Ad personalisation: GameDen → Settings → Privacy Options (shown wherever the consent form applies).
- Notifications: iOS Settings → Notifications → GameDen.
- Game Center: iOS Settings → Game Center. GameDen plays normally without it.
- Ads entirely: GameDen Pro removes every ad.
Children
GameDen is not directed at children under 13 and we do not knowingly collect personal information from them. There are no accounts, no profiles, no chat and no way for players to contact each other in the app.
Your rights
Because GameDen holds no account, there is no profile for us to look up. If you have sent feedback and want it deleted, email hello@playgameden.com from the address you used and we will remove it. Deleting the app removes everything held on your device. Under UK GDPR you may also complain to the Information Commissioner's Office.
Third parties
The services named above have their own policies: Google (Firebase and AdMob) and Apple (Game Center and the App Store).
Changes
If this policy changes, the date at the top changes with it. Material changes will be noted in the app's release notes.
