PaperFlip
Last updated: 1 September 2026 · Effective: 1 September 2026
The short version. PaperFlip has no accounts and no login. Your score and settings stay on your device. The game shows ads and uses crash reporting and analytics, which involves third-party SDKs collecting limited technical data. Personalised advertising only happens if you allow tracking when iOS asks you.
PaperFlip ("the App") is developed and published by luohongbiao ("we", "us").

Postal address: Please contact us by email. EU Digital Services Act trader details (including postal address) appear on the PaperFlip product page in the App Store.
The App has no registration, no login, no user profile, and no contact form. We never ask for your name, email address, phone number, photos, contacts, location, or microphone access. The App does not contain a chat or any other way for users to communicate.
The following is written to your device's local storage (UserDefaults) and never transmitted to us:
Deleting the App deletes all of it. We hold no server-side copy, so there is nothing for us to restore — with one exception: your "Remove Ads" purchase is tied to your Apple Account by Apple, not by us, and can be recovered with Settings → Restore Purchases inside the App.
We use the following services. Each one collects data under its own privacy policy, and each is contractually a processor or independent controller as described below.
| Service | Purpose | Data involved |
|---|---|---|
| Google AdMob | Showing interstitial and rewarded-video ads, which fund the App | Advertising identifier (IDFA, only with your permission), IP address, device and OS model, ad interaction events, coarse region |
| Firebase Analytics | Understanding how far players get, so difficulty and ad frequency can be tuned | Pseudonymous app-instance identifier, device and OS model, session and gameplay events (run length, score at death, rewarded-ad views) |
| Firebase Crashlytics | Diagnosing crashes | Crash stack traces, device and OS model, App version |
| Firebase Remote Config | Adjusting difficulty constants and ad pacing without shipping an update | Fetches configuration values; sends device and OS model |
| Apple App Store / StoreKit | Processing and verifying in-app purchases | Handled entirely by Apple. We receive no payment details, and we never see your card number, name, or billing address. |
Their policies: Google Privacy Policy, Firebase Privacy and Security, Apple Privacy Policy.
On first launch, iOS may ask whether PaperFlip can track your activity across other companies' apps and websites. This controls access to your device's advertising identifier (IDFA).
You can change this at any time in iOS Settings → Privacy & Security → Tracking.
If you are in a region covered by the GDPR, the App presents a consent dialog (Google's User Messaging Platform) before any advertising SDK is initialised. You may accept or reject the use of your data for personalised advertising.
You can revisit and withdraw that choice at any time via Settings → Ad Preferences inside the App.
We do not operate our own servers or databases, so we retain nothing ourselves. Data held by the services above is retained according to their own schedules; Firebase Analytics event data is configured to the shortest retention period offered.
The services listed in section 4 are operated by companies based in the United States and may process data outside your country. Those transfers rely on the European Commission's Standard Contractual Clauses and, where applicable, the EU-U.S. Data Privacy Framework.
PaperFlip is not directed to children and is not listed in the App Store Kids Category. We do not knowingly collect personal information from children under 13 (or the equivalent minimum age in your country). If you believe a child has provided us with personal information, contact us and we will act on it promptly.
Depending on where you live, you may have the right to access, correct, delete, or port your data, to object to or restrict processing, and to withdraw consent. Because the App holds no account and no server-side records, the most direct routes are:
California residents: we do not sell or share personal information for cross-context behavioural advertising within the meaning of the CCPA/CPRA when you decline tracking. You may exercise CCPA rights using the same email above, and we will not discriminate against you for doing so.
All network traffic uses HTTPS. Since the App stores no personal data remotely and holds no credentials, the attack surface is limited to your own device.
If this policy changes materially, we will update the date at the top and, where the change requires it, request fresh consent. Continued use after an update constitutes acceptance of the revised policy.
