This Privacy Policy explains how BlinkRead ("we," "our," or "the app") collects, uses, and protects your information when you use our mobile application. BlinkRead is a speed reading app that uses RSVP (Rapid Serial Visual Presentation) technology to help you read faster. By using the app, you agree to the practices described below.
To provide the app's features, we collect the following:
When you sign in with Google or Apple, we receive your email address,
display name, and a unique user identifier provided by the sign-in provider.
Sign in with Apple may provide a relay email (@privaterelay.appleid.com) instead of
your real address if you choose to hide it.
Purchase receipts and subscription status are handled by Apple (App Store) or Google (Play Store) and relayed to our subscription provider, RevenueCat, to unlock premium features. We do not see or store your payment method, card number, or billing address.
Standard platform-level information such as device model, OS version, and anonymous installation identifiers may be processed by our service providers (Firebase, Google, Apple) to keep the app running. BlinkRead does not include any third-party advertising or marketing SDKs.
We do not sell your personal information, and we do not use it for advertising, profiling, or any purpose unrelated to operating the app.
We use a small number of trusted service providers. Each has its own privacy policy that governs the data they process on our behalf.
| Service | Purpose | Policy |
|---|---|---|
| Firebase Authentication | Sign-in and account management | Link |
| Cloud Firestore | Storing library metadata, reading progress, preferences | Link |
| Firebase Storage | Storing uploaded EPUB files for your library | Link |
| Google Sign-In | Optional sign-in method | Link |
| Sign in with Apple | Optional sign-in method | Link |
| RevenueCat | Subscription management and receipt validation | Link |
| Apple App Store / Google Play | Processing purchases and subscriptions | See each store's policy |
BlinkRead offers optional premium subscriptions (monthly, annual) and a lifetime purchase. Monthly and annual subscriptions may include a 3-day free trial for eligible new customers. Payments are processed exclusively by Apple or Google; we never receive your payment credentials.
Subscriptions auto-renew at the end of each billing period unless cancelled at least 24 hours beforehand through your device's store settings. You can manage or cancel subscriptions at any time from the App Store (iOS) or Google Play (Android).
We keep your account data for as long as your account is active. When you delete your account, we remove your profile, library metadata, reading progress, and uploaded files from our active systems within a reasonable period. Backups may retain copies for a short additional window before being overwritten in the normal course of business.
Depending on your jurisdiction (GDPR, CCPA, and similar laws), you have the right to:
BlinkRead is not directed to children under 13 (or the minimum age required in your country). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it.
We rely on industry-standard security practices from our infrastructure providers, including encrypted connections (HTTPS/TLS) for all data in transit, Firebase security rules to restrict access to your data, and platform-level protections provided by iOS and Android. No method of electronic storage or transmission is 100% secure, but we work to protect your data using commercially reasonable safeguards.
We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last updated" date at the top of this page and, where appropriate, notify you inside the app. Continued use of the app after the changes take effect constitutes acceptance of the updated policy.
