Reports are saved on the Siren CB Chatter server and every one is checked by a person. Nobody is banned automatically.
Blocked users
You won't hear or see anyone you block: their voice, push-to-talk and messages are hidden for you.
Delete my account and data
This deletes your account id, handle and block list from the server and clears this device. Reports you filed are kept without your account id so safety reviews can finish. Details · Privacy policy (draft)
Are you sure? This can't be undone. Type DELETE to confirm.
Before you start (draft notice):
This app is for adults 18 and over.
The app uses your microphone only while you hold push-to-talk or tap your earbud to key it. Your voice is relayed live to others on the channel and is not recorded or stored, except a short clip saved when someone reports a talker.
If your phone supports it, your phone turns the words you speak while keyed up into text on your own device (your phone maker or browser, such as Apple or Google, may process the audio to do this). That text is shown on screen to you and to others on the channel. The server relays it live and does not store it.
The server never stores your raw IP address. It keeps a scrambled (hashed) IP record for spam limits and bans, deleted automatically after 7 days. If you report someone, the last 30 seconds of their audio is saved with the report and deleted automatically 30 days after a person closes the review; no other audio is saved. Privacy policy (draft)
