Room Audio Check

Cookie Policy

This Cookie Policy explains how Room Audio Check uses cookies and local browser storage.

Last updated July 27, 2026

1. Current Cookie Use

Room Audio Check currently uses essential cookies only. These cookies support authentication, OAuth security, and signed-in session continuity. We do not currently use advertising cookies, retargeting cookies, or third-party analytics cookies.

2. Cookies and Storage We Use

authjs.session-token / __Secure-authjs.session-token
Essential HTTP-only Auth.js cookie used to keep a Client Explorer controller signed in with an encrypted JWT session. It expires after about 12 hours.
authjs.csrf-token / __Host-authjs.csrf-token
Essential HTTP-only Auth.js cookie used to protect sign-in, sign-out, and other auth state-changing requests from CSRF.
authjs.callback-url, authjs.pkce.code_verifier, authjs.state
Essential HTTP-only Auth.js cookies used during Client Explorer OAuth redirects, callback validation, PKCE, and state checks. OAuth flow cookies expire after about 15 minutes.
roomAudioCheckControllerSessionId
Local browser storage used to remember the last controller session ID on the same browser. It is not sent as a cookie on every request.
Legacy rebrand names
Browsers that used the app before the Auth.js migration or rebrand may briefly retain old room_audio_check_ce_*, sound_check_ce_*, or soundCheckControllerSessionId storage until they expire or are cleared.

3. Similar Technologies

We may use browser APIs such as microphone permission prompts, media playback state, clipboard actions, and local storage to run diagnostics. These are not advertising identifiers, but they may be controlled through browser settings.

4. Third Parties

Hosting providers, authentication providers, browsers, Apple AirPlay, and other services may set or read their own cookies or local storage on their own domains. Their use is governed by their own policies.

5. Your Choices

  • You can block or delete cookies in your browser settings.
  • If you block essential cookies, Client Explorer sign-in and TV session creation may not work.
  • You can clear local storage to remove the remembered controller session ID.
  • You can use browser site settings to revoke microphone permission.
