Security Key Bridge Privacy Policy
Effective 1 November 2026. This privacy policy applies to the Security Key Bridge Android app and its Wear OS companion app, published on Google Play by QTComs, Inc.
Summary
- We collect no personal data. The app has no internet permission, so it cannot send anything to us or to anyone else over the network.
- No account, no advertising, no analytics, no tracking, and no third-party code that reports usage.
- What the app needs is stored on your phone. It leaves your phone only to go to your own devices: your computer over Bluetooth, and your watch.
- Uninstalling the app deletes everything it stored.
Who we are
QTComs, Inc. (7491 NW 40th St, Chiefland, FL 32626, USA) publishes Security Key Bridge. Privacy questions: appsupport@qtco.ms.
What the app does
Security Key Bridge makes your phone a Bluetooth security key for your computer. It relays the computer's sign-in requests to the authenticator in your NFC card or implant, or in a security key plugged into the phone, and relays the answers back. Your passkeys and private keys never leave the card, implant or key. Your PIN is encrypted between the computer and the authenticator, so the app cannot read it.
Data the app stores on your phone
| Data | Why |
|---|---|
| Your settings (for example sounds, and whether to use a plugged-in security key) and whether setup is done | To work the way you chose |
| The Bluetooth addresses of the computers you paired, and when each one last connected | To list your computers and reconnect the most recent one |
| The public capabilities of your card or implant (what it reports to any computer that asks), including whether it only speaks the older U2F protocol | So a computer can be answered without a tap |
The app does not store your keys, your PIN, the websites you sign in to, or anything a website sends.
Data that leaves your phone
We receive none of it. It goes only to your own devices: - Your computer, over Bluetooth. The authenticator's answers go to the computer you paired, over the Bluetooth link between your phone and your computer, which is encrypted with the keys created when you paired them. - Your watch. The watch app shows what to do next and which computer is connected. This uses the Wear OS Data Layer in Google Play services: over Bluetooth, or, when the watch isn't reachable that way, through Google's servers, end-to-end encrypted with keys that only your phone and watch hold. - Android backup, if you use it: the app's settings and the list of paired computers can be included in your Android backup and in a transfer to a new phone. Android encrypts backups with your screen lock.
We do not sell, share or transfer data to any third party.
Permissions
- Nearby devices (Bluetooth): to be a security key for your computer and to pair with it.
- NFC: to talk to your card or implant.
- Notifications: to tell you when your computer asks for your security key while the app is in the background, and to let you stop it.
- Foreground service (connected device): to stay connected to your computer while the app is in the background.
- USB, when you plug in a security key and allow it; vibration, for feedback.
Security
The app keeps what it stores in its private storage on your phone. It never holds your keys or reads your PIN. Data sent to your computer and watch is encrypted in transit, as described above.
Retention and deletion
Everything the app stores stays on your phone until you delete it: uninstall the app, or clear its storage in Android's settings. To remove a computer, unpair it in the phone's and the computer's Bluetooth settings. We hold no copy, so there is nothing for us to delete.
Children
The app is not directed at children under 13, and it collects no personal information from anyone.
Your rights
Depending on where you live (for example under the GDPR in Europe or the CCPA in California), you may have rights to access, correct or delete personal data a company holds about you, and to complain to a data protection authority. We hold no personal data from this app; if you have a question, write to appsupport@qtco.ms.
Changes to this policy
If this policy changes, we will update this page and its effective date. If the app ever starts to collect data, this policy and the app's Google Play listing will say so before it does.
