1. Who provides this app
| App | Duel Alley (Japanese title: タイマン横丁) |
| Developer | Individual developer (DAGZO) |
| Contact | dagzo.app@gmail.com |
2. The short version
This app collects nothing about you, and sends nothing anywhere.
Player names, player photos, and match records stay only on your device.The developer cannot see any of it.
3. What is stored on your device
| What | Where | When it goes away |
|---|---|---|
| Player names (up to 6 characters) | App-private storage | When you delete the player, or uninstall the app |
| Player marks (built-in glyph or a photo) | Same (photos: one cropped image) | Same |
| Head-to-head records (wins, streaks) | Same | Same |
| Which player sits in which seat | Same | Same |
| Per game: how many times it was opened, and how many matches finished | Same | When the app is uninstalled |
Uninstalling the app deletes all of it. The developer keeps no copy.
The "opened / finished" counts exist so the developer can see which games get played,but they are never sent anywhere. They are counted on your device and shown in theapp's "Records" screen.
4. Photos
You can use a photo as a player's mark.
- Tapping "Photo" opens the Android photo picker; "Camera" opens your camera app. The app itself never asks for a permission
- Only the single image you pick is used. The app does not read your library
- The image is cropped to a circle and saved as one 256-pixel image in app-private
storage. The original photo is not stored
- Deleting a player deletes their photo. Replacing a mark deletes the old photo
- Photos are never uploaded. No face detection or analysis is performed
5. Network
This app does not connect to the internet.
- No ads
- No analytics or tracking SDKs
- No in-app purchases
- No account or sign-in
6. Sharing with third parties
None. The developer never receives your data, so there is nothing to share.
7. Children
The app is designed for two adults playing together, though playing with a childis also expected. On Google Play the target audience is declared as 18+; the app isnot submitted as a children's app.
You may register a child's name or photo as a player, but that data never leaves thedevice (sections 3 and 4).
8. Permissions
This app requests no Android permissions at all.
| What it does | How |
|---|---|
| Pick a photo | Opens the Android photo picker. Only the one image you pick is handed over; no permission grant is needed |
| Take a photo | Opens your camera app. Only the one photo taken is handed over |
| Keep the screen awake | Marks the window as "do not dim" while the match screen is open. No permission needed |
It does not hold the internet permission either (there is no declaration for it in the app).
9. Access and deletion requests
The developer holds no data, so there is nothing to disclose, correct, or delete.You can delete on-device data yourself by removing players in the app, or byuninstalling the app.
10. Changes
If this policy changes, this page is updated. Significant changes are also noted in thestore's "What's new" section.
