Effective date: 5 November 2026
Screen Distance for Android ("the app") helps reduce eye strain by reminding you when you hold your phone or tablet too close to your eyes. This policy explains what the app does with information on your device. In short: the app does not collect, store, or share any personal data, and it cannot connect to the internet.
The app is published by MB Apps. Co. ("we", "us").
Personal data collected - None
Data shared with third parties - None
Photos or videos saved - Never
Internet access - None. The app has no internet permission, so it is technically unable to send data anywhere.
Advertising or analytics - None
Accounts or sign-in - None
The app uses the front camera to estimate the distance between your eyes and the screen.
Camera frames are analysed on your device, in memory, in real time, using Google's ML Kit face detection library, which is built into the app and runs offline.
From each frame, the app works out only the approximate position of your eyes to calculate a single number: the estimated viewing distance.
Each frame is discarded immediately after analysis. No photos, videos or face data are saved, and nothing is used to identify you. The app does not perform facial recognition.
To save battery, the camera runs only in brief checks while the screen is on and unlocked. It never runs while the screen is off. Android shows its green camera indicator whenever the camera is in use.
The app reads the accelerometer and proximity sensor to decide when a distance check is worth doing, for example skipping checks while the device is resting on a table. These readings are processed in memory and are not stored.
To avoid covering the screen during a call, the app checks whether the device's audio is currently in call mode. It does not have access to your calls, contacts, phone number or call history, and it requests no phone permissions.
The app saves a small amount of information locally on your device only:
Settings: on/off state, alert distance, delay, check frequency, units and calibration factor.
Today's summary: simple counters for the current day (number of checks at a healthy distance, number of checks that were too close, and how many times the reminder appeared). These are reset each day and no history is kept.
Parent lock PIN (optional): stored only as a salted cryptographic hash, never as the PIN itself.
Pro status: whether the one-time Pro upgrade has been purchased.
This information never leaves your device through the app. If you have Android's device backup turned on, Android may include these settings in your device backup to your Google account, under Google's Privacy Policy. You can turn backup off in your device's settings.
You can delete all of it at any time by uninstalling the app, or under Settings → Apps → Screen Distance → Storage → Clear data.
The optional one-time Pro upgrade is processed entirely by Google Play. We never receive or handle your payment details. Google Play tells the app only whether the upgrade was purchased, and the app checks this on-device. Google's handling of your purchase is covered by the Google Play Terms of Service and Google's Privacy Policy.
Permission - Why it's needed
Camera - Estimate your viewing distance on-device (see section 2).
Display over other apps - Show the "too close" reminder on top of the app you're using.
Notifications (optional) - Show that monitoring is on, and a "Tap to resume" message after a restart.
Run in the background (foreground service) - Keep monitoring while you use other apps.
Start at boot - Resume monitoring after your device restarts.
Google Play billing - Offer the optional one-time Pro upgrade.
The app does not request internet, location, contacts, storage, microphone or phone permissions.
The app includes Google's ML Kit (on-device face detection) and the Google Play Billing Library. ML Kit runs fully offline inside the app. Because the app has no internet permission, neither component can send data from the app over the network. Billing requests go through the separately installed Google Play Store app.
Screen Distance is designed to be safe for families and children. The app does not collect personal information from anyone, including children, and contains no ads, no analytics, no social features and no links that collect data.
Because no data leaves your device and nothing sensitive is stored, there is no account, server or database that could be breached. The optional parent PIN is stored only as a salted hash.
If this policy changes, we will update the effective date above and publish the new version at the same address. Material changes will also be described in the app's release notes.
