Effective date: July 10, 2026
Short version: we collect nothing about you. Everything runs on your device.
Glasses Radar does not create user accounts, does not upload your scans, and does not know who you are. Signals detected near you stay on your device. The only network request the app ever makes is an optional signed download to refresh the device fingerprint database — that is a pull from our server, not a push of your data to it.
Glasses Radar is developed and published independently. For privacy enquiries contact: hello@glassesradar.app.
This policy describes how the Glasses Radar mobile application (iOS and Android) and the website at glassesradar.app handle information. It applies to all users worldwide.
Glasses Radar passively listens for publicly broadcast Bluetooth and (on Android) Wi-Fi signals from nearby devices. It compares those signals against a local fingerprint database of known camera-enabled smart glasses hardware, and notifies you when a potential match is nearby.
The app does not:
To provide detection, the app processes the following information locally on your device. None of this is transmitted to us or any third party:
| Data type | Why it is processed | Leaves your device? |
|---|---|---|
| Bluetooth advertisement packets from nearby devices | Matched against fingerprint database to identify camera-glasses hardware | No |
| Wi-Fi probe and beacon frames from nearby devices (Android only) | Used to detect "active" state (streaming, capturing) | No |
| Device manufacturer data bytes in BLE advertisements | Pattern-matched against known camera-glasses signatures | No |
| Alert history (local) | Displayed to you in the app; stored only on your device | No |
The app can optionally download a signed update to its on-device fingerprint database from our servers. This request:
| Permission | Platform | Why it is needed |
|---|---|---|
| Bluetooth / Nearby Devices | iOS & Android | Core detection mechanism — scans for public BLE advertisements from nearby devices. |
| Location (Approximate or Precise) | iOS & Android | Required by the operating system to allow any app to scan for Bluetooth devices. Glasses Radar does not use this permission to track your location, store your location, or infer where you have been. |
| Nearby Wi-Fi Devices | Android only | Enables detection of the "active" signal state when camera glasses are streaming or offloading captures. |
| Notifications | iOS & Android | Sends you an alert when a matching device is detected nearby. |
The app and website use a minimal set of third-party services:
We do not use advertising SDKs, analytics SDKs inside the app, crash-reporting services that transmit personal data, or any SDK that shares data with third parties for marketing purposes.
We retain no personal data on our servers because we do not collect any. On your device, alert history and app settings are stored locally and can be cleared by deleting the app.
Glasses Radar is not directed at children under 13 (or 16 where applicable under local law). We do not knowingly collect information from children. If you believe a child has used the app in a jurisdiction where this is restricted, contact hello@glassesradar.app.
Because we do not collect or retain personal data, most data subject rights (access, deletion, portability) do not practically apply — there is nothing to access, delete, or export on our side. However, we respect and respond to all enquiries:
This website and the app do not track users across third-party websites or services. We honour Do Not Track signals in the sense that we do not engage in cross-site tracking at all.
The fingerprint database is cryptographically signed; the app verifies the signature before applying any update. All network communication between the app and our servers uses HTTPS/TLS. Because we do not store personal data, the attack surface for a data breach involving your personal information is effectively zero.
The fingerprint database update is served from servers that may be located outside your country. No personal data is transferred in this process — only a signed binary file is downloaded to your device.
If we make material changes — for example, if a future app version begins collecting data it currently does not — we will update this policy, post the new effective date, and notify users via an in-app notice. Your continued use of the app after a material change constitutes acceptance of the updated policy.
