Privacy Policy
Briki'n Roll (the "App") is a Rube Goldberg-style puzzle game in which you build a contraption to roll a ball to the goal. The App is for all ages / family-friendly, shows no advertising, and does not track you. This policy explains what information the App does and does not handle.
1. Information We Collect
All information the App collects is anonymous and does not identify you personally. We do not collect your name, email address, or phone number (see Section 2).
1-a. Usage & Diagnostic Data (anonymous)
To improve the game and fix problems, the App may send the following anonymous data to our backend (a server hosted on Cloudflare):
- An anonymous in-app ID — a random identifier generated on your device. It is not linked to your name, email, Apple ID, or phone number. It is kept on the device even if you reinstall the App, so our statistics are not double-counted.
- A session ID — a temporary identifier assigned each time the App launches.
- App version / build number.
- Device information — the device model identifier and OS version (e.g., "iPhone17,2 / iOS 26.5"). This does not uniquely identify a single device.
- Gameplay events and their timestamps — building a course, starting a run, reaching the goal, failing (and the type of failure), screen views, progress (courses cleared), in-app medal balance and changes, the IDs of equipped cosmetic items, and the device display language. The layout data of courses you create is sent only for publishing (Section 1-c) or backup (Section 1-f), and is not part of this statistics data.
- Error / diagnostic information — error messages and technical logs (stack traces) when the App crashes or hits an error.
- Country code — to understand which countries players are in, our server infers an approximate country (e.g., JP / US) from the connecting IP address. We do not store the IP address itself — only the two-letter country code.
Purpose: used only to understand how the game is played, to improve it, and to find and fix bugs and crashes.
1-b. Push Notifications (only if you allow them)
We offer push notifications to let you know about new courses and announcements. If you enable notifications, the notification service OneSignal handles the push token and device information (model, OS, language) needed to deliver them. You can turn notifications off at any time in your device settings.
1-c. Posting to "Everyone's Courses" (only if you post)
The app includes "Everyone's Courses," where you can publish a course you built so other players can download it. Only when you choose to post, the following is sent to our server and made public to other players:
- The course layout data — the contents of the course you posted.
- Course title (up to 30 characters) and creator name (up to 32 characters) — both are free text that you type. Please do not enter real names, email addresses, school names, or anything else that could identify you or another person. Whatever you type is shown to other players as-is.
- Briki'n's cosmetic setup — the identifiers of the items worn at the time of posting (hat, glasses, and so on).
- The anonymous in-app ID — used to identify your own posts, prevent duplicate "likes," and process reports and blocks (the same anonymous ID as in 1-a; it is not linked to your name or any personal information).
Reporting and blocking: You can report inappropriate posts from within the app, and you can block a creator so their courses are no longer shown to you. Reported posts are reviewed by us and removed if they violate our terms.
Removing a post: If you would like a post taken down, please contact us using the details in Section 7.
1-d. Game Center (only if you use it)
We use Apple Game Center for leaderboards and achievements. Signing in to Game Center and recording scores/achievements is managed by Apple under Apple's privacy policy. We only submit scores and achievement progress to Game Center; we do not receive your Apple account information.
1-e. In-App Purchases
The App offers a paid "Full Version" (one-time purchase). Purchases and payments are processed by Apple (the App Store); we never receive payment details such as credit card numbers. The only information we receive is whether the purchase has been made.
1-f. Automatic Course Backup
So that the courses you build are not lost when you switch devices or reinstall the App, saving a course automatically sends its layout data (the arrangement of devices) together with an anonymous backup ID to our server (hosted on Cloudflare) for safekeeping.
- Only the course layout data is stored. No text you typed (titles, names) is included.
- The backup ID is a random identifier generated by your device and is not linked to your name, email, or Apple ID. So that restoring works after a device change, it is synced only between your own devices via iCloud Keychain (an Apple feature). We never learn your Apple ID.
- Backups are never shown to other players (only posts under Section 1-c are public).
- If you would like your backup deleted, contact us using the details in Section 10.
2. Information We Do NOT Collect
The App does not collect personally identifiable information (PII), including:
- Name, email address, phone number, or postal address
- Contacts / address book, or calendar
- Precise location (GPS) — the App does not request location permission
- Health or fitness data
- Payment details such as credit card numbers (purchases are handled by Apple)
- Text you type (except a course title and creator name when you post — see Section 1-c; nothing else you type is transmitted)
- Browsing or search history
- Advertising identifiers (IDFA) or other tracking identifiers
3. How We Use Information
We use the anonymous data only to:
- Provide and improve the App
- Find and fix bugs and crashes
- Deliver notifications (if you have allowed them)
- Provide leaderboards and achievements (Game Center)
We do not use this data for advertising or sell it to anyone.
4. Photos & Recordings
The App can record your gameplay and save it to your camera roll, or let you share it via the share sheet. For this, the App may ask for permission to save to your photo library and for the microphone.
- Recordings and images are created on your device and saved to your camera roll.
- If you share, they go only to the people or apps you choose.
- We (the developer) do not receive these recordings, audio, or photos.
5. No In-App Ads, No Tracking
- The App shows no advertising inside the app.
- To measure how well our own ads for the App (for example on TikTok and X) lead to installs, the App includes the measurement service AppsFlyer (version 1.4.5 and later).
- The App does not request App Tracking Transparency (ATT) permission. It does not use the advertising identifier (IDFA) and does not track you across other companies' services. Ad performance is measured with aggregated methods that do not identify individuals, such as Apple's SKAdNetwork.
6. Third-Party Services
The App uses the following third-party services. Their handling of data is governed by their own privacy policies:
- Apple (App Store, Game Center, and the APNs push delivery infrastructure) — https://www.apple.com/legal/privacy/
- OneSignal (push notification delivery) — https://onesignal.com/privacy_policy
- Cloudflare (hosting for the backend that receives the anonymous usage/diagnostic data) — https://www.cloudflare.com/privacypolicy/
- AppsFlyer (install measurement for our ads; receives app launches, technical device information such as model, OS and language, an approximate region inferred from the IP address, an install identifier issued by the App, and the identifier for vendor (IDFV); it does not receive the advertising identifier (IDFA)) — https://www.appsflyer.com/legal/services-privacy-policy/
Ad measurement results may be shared, in a form that does not identify individuals, with TikTok (privacy policy) and X (privacy policy), where we run our ads. This data is used only to measure ad performance.
If you want your measurement data deleted: please contact us via the Contact button at the bottom of this page, and we will ask AppsFlyer to delete it.
7. Children's Privacy
The App is intended for all ages and family use.
- We do not collect personal information such as name or email.
- We show no behavioral / targeted advertising (there is no advertising inside the app).
- We do not track children. Measurement of our own ads uses aggregated methods that do not identify individuals.
If you are a parent or guardian with any concerns, please reach us via the Contact button at the bottom of this page.
8. Data Retention & Deletion
- Anonymous usage/diagnostic data is kept only as long as needed to improve the game.
- Because this data is anonymous and not linked to an individual, we generally cannot identify data belonging to a specific person.
- Progress and save data stored on your device is removed from the device when you delete the App.
- Automatic course backups (Section 1-f) are kept so they can be restored. To have yours deleted, contact us — tapping the version label at the top right of the title screen shows and copies your backup ID, which lets us delete it quickly.
- For deletion requests or questions about your data, use the Contact button at the bottom of this page.
9. Changes to This Policy
We may revise this policy as features change. If we make a significant change, we will update the "Last updated" date on this page.
