Privacy Policy
At Arcane Orbit, we respect your privacy. This policy explains what data the Dual N-Back Extreme app collects, how it is used, and how it is protected.
1. Information We Collect
We do not require any personal information to use the app, and we do not collect your name or payment details. The only personal information we ever receive is an email address you may optionally provide when sending us feedback (see 1.3). Beyond that, the app only handles the following limited data:
1.1 In‑App Purchase Data
- Purchase receipts and subscription status are validated using RevenueCat.
- No personal payment details are stored by us.
1.2 Usage & Crash Data
- We use Firebase Analytics and Firebase Crashlytics to understand app performance, detect crashes, and improve user engagement. As part of Google Analytics, information such as device type, app interactions, and coarse location data may be collected.
- We use Mixpanel to analyze how users interact with the app. Mixpanel receives:
- App interaction and usage events
- Basic device metadata (such as device model and OS version)
- An anonymous user identifier used to associate events across sessions
- Mixpanel does not receive your name or payment details. It receives an email address only if you voluntarily enter one in the in-app feedback form (see 1.3).
1.3 In‑App Feedback
- When you submit feedback through the app, we receive your message, the feedback category, your app version, device model, and iOS version, along with the same anonymous user identifier used for analytics. This is transmitted via Mixpanel.
- You may optionally include an email address if you would like a reply. It is used only to respond to your message and is never used for marketing or shared with anyone else.
1.4 Game Center Leaderboards
- If you choose to sign in to Apple's Game Center, your best training level and accuracy are submitted to global leaderboards, where they appear alongside your Game Center display name.
- Game Center sign-in is optional; the app is fully playable without it. Game Center data is collected and managed by Apple under Apple's Privacy Policy.
2. How We Use Information
- Subscription Validation – On‑device purchase receipts and subscription status are checked only to confirm active subscriptions.
- App Improvement – Crash and engagement data help us fix bugs and enhance the user experience.
- Analytics & Product Improvement – Analytics data helps us understand how the app is used, identify technical issues, and improve the overall user experience.
- Support & Feedback – Feedback messages help us fix bugs and prioritize features. An email address, if you provide one, is used solely to reply to you.
Your purchase receipts are used only for validation with RevenueCat and are not used for any other purpose.
3. Third‑Party Services
- RevenueCat – Used solely for receipt validation and subscription status checks. See RevenueCat’s Privacy Policy: revenuecat.com/privacy.
- Firebase (Google) – Used for crash reporting and usage analytics. See Firebase Privacy Policy: firebase.google.com/support/privacy.
- Mixpanel – Used for product analytics (event tracking and user behaviour analysis) and to deliver in-app feedback messages to us. Mixpanel may receive device metadata, an anonymous user ID, and — only if you provide it in the feedback form — an email address. See Mixpanel's Privacy Policy: mixpanel.com/legal/privacy-policy.
- Apple Game Center – Used for optional leaderboards. See Apple's Privacy Policy: apple.com/legal/privacy.
4. Data Storage & Security
- Game progress, settings, and purchase validation tokens are stored locally on your device.
- Purchase information may also be sent to RevenueCat for validation.
- We do not store personal data on our servers.
5. Your Rights
We do not collect personal data such as your name or payment details. We do collect anonymous usage data and a persistent anonymous identifier linked to your device, and — only if you choose to provide it when sending feedback — an email address. If you wish to request deletion of your analytics data (including any email address you provided), contact us at the email below and we will submit a deletion request to Mixpanel on your behalf. For purchase-related inquiries, please contact Apple Support or manage your subscription directly through the App Store.
6. Changes to This Policy
We may update this Privacy Policy occasionally. If changes are made, the updated version will be posted here. Continued use of the app after updates means you accept the revised policy.
