Privacy Policy

At BlinkGo, your privacy is not an afterthought — it is a core part of how we built this product. BlinkGo is a screen-time control app that helps you break phone addiction by requiring a simple blink challenge to unlock blocked apps. Everything that makes BlinkGo work happens entirely on your device. We do not run servers that store your data. We do not know who you are. We do not want to.

This Privacy Policy explains what information BlinkGo accesses, why, and what we do (and do not do) with it. If you have any questions, reach out to us at nagalakshmes@gmail.com.

No account, no profile, no tracking

BlinkGo does not ask you to create an account. You do not provide your name, email address, phone number, or any other personal identifier to use the app. There is no login. There is no profile. There is no way for us to connect app usage back to any individual person.

Camera & blink detection

BlinkGo uses your device's front-facing camera to detect blinks in real time. This is the core feature of the app — when you try to open a blocked app, the camera activates briefly to confirm you blinked intentionally before granting access.

Here is exactly what happens with your camera:

• Camera frames are analysed entirely on your device using Apple's Vision framework (iOS) or ML Kit (Android). No image processing happens on our servers because we have no servers involved.
• No photos, video clips, or facial images are ever saved to your device storage.
• No camera data is ever transmitted to BlinkGo or any third party.
• We do not create, store, or infer any facial profile, face map, or biometric identifier from your camera input.
• Camera access is only requested at the moment you attempt to open a blocked app. It is not running in the background.

You can revoke camera permission at any time in your device Settings. Doing so will disable the blink-unlock feature, but you can still use all other parts of the app.

Screen Time & app blocking

On iOS, BlinkGo uses Apple's Screen Time API (FamilyControls, ManagedSettings, and DeviceActivity frameworks) to block the apps you choose. The list of apps you select to block lives entirely within Apple's on-device frameworks. BlinkGo never reads or stores the names of blocked apps on any external server.

On Android, BlinkGo uses the Accessibility Service permission to detect when a blocked app moves to the foreground, at which point it overlays the blink challenge. This permission is used solely to intercept app launches. It does not read screen content, record inputs, or access any data inside other apps.

What is stored on your device

BlinkGo stores the following data locally on your device only. None of it ever leaves your device:

• Your list of blocked apps and schedules.
• Your chosen blink-challenge difficulty level.
• Your streak history and earned badges.
• Aggregate blink counts used to calculate your dopamine score.
• App preferences and settings.

This data is tied to your device, not to a person. It is never synced to a cloud service by BlinkGo. Uninstalling the app deletes all of it permanently.

Analytics

The BlinkGo website (blinkgo.fit) uses Umami Analytics, a privacy-respecting, cookie-free analytics tool that collects only anonymous aggregate page-view counts. No personally identifiable information is collected from website visitors.

The mobile app does not include any third-party analytics SDKs, advertising SDKs, or crash-reporting tools. If this changes in a future version, this policy will be updated before the release.

Purchases & subscriptions

BlinkGo Premium is available as an auto-renewing in-app subscription purchased through the Apple App Store or Google Play Store. All payment processing is handled entirely by Apple or Google. BlinkGo never receives, sees, or stores your payment card details or billing information.

Data sharing & third parties

We do not sell your data. We do not share your data. We do not rent your data. Because BlinkGo does not collect personal data in the first place, there is nothing to share with advertisers, data brokers, or anyone else.

Children's privacy

BlinkGo is not directed at children under the age of 13. We do not knowingly collect any information from children under 13. If you are a parent or guardian and believe your child has used BlinkGo in a way that raises privacy concerns, please contact us at nagalakshmes@gmail.com and we will address your concerns promptly.

Security

Because BlinkGo operates entirely on-device and never transmits personal data to external servers, the attack surface for a data breach is minimal. Local data is protected by your device's built-in security (iOS Secure Enclave, Android Keystore) and is accessible only while the app is installed.

Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will revise the effective date at the top of this page. If we make a material change to how we handle your data, we will notify you through the app or via an app store update notice. Your continued use of BlinkGo after any change means you accept the updated policy.

The latest version of this policy is always available at blinkgo.fit/privacy.
