Your Briar link contains a public key and it is safe to publish in the same way as a PGP public key. If you want to contact someone via Briar, both of you need to add each other's links.

# Can people track my online status if I publish my `briar://` link?
|
|
|
|
|
|
No, your online status isn't exposed by publishing your `briar://` link. For strangers to be able to connect to you you must first add them as a contact, otherwise they won't know where to find you in the Tor network.
|
|
|
|
|
|
For a more technical explanation, for each new contact a separate Tor hidden service gets created whose address depends on both your own and your contact's public key. See the [Bramble Rendezvous Protocol](https://code.briarproject.org/briar/briar-spec/-/blob/master/protocols/BRP.md#2-the-rendezvous-protocol) for more information.

* "Let app always run in background" (on some phones this is called "Ignore battery optimizations"). Briar needs this permission so it can receive messages while the app is in the background.

* Permission to access the camera. Briar asks for this permission when adding a contact who's nearby so that Briar can scan a QR code. Briar doesn't use the camera at any other time.

* Permission to access your location. Briar asks for this permission when adding a contact who's nearby so that Briar can discover nearby Bluetooth devices. This is required by Android because in certain cases, knowing that a certain Bluetooth device is nearby might reveal your location. Briar doesn't store, track or share your location in any way other than discovering Bluetooth devices. |
