Cookies are small pieces of data a website asks your browser to keep and send back to it. Web storage (local storage and session storage) keeps data in your browser without sending it with every request; local storage stays until deleted, session storage is deleted when you close the tab. We use one login cookie, both kinds of web storage and, only if you turn on Analytics, the analytics cookies listed in section 3.
SynchroVerse uses cookies and similar technologies for several purposes:
Used for logging in, security, remembering your cookie choice, and running the feature you are using. Your cookie choices do not turn them off:
We save some settings in your browser so they stay the way you left them: light or dark theme, microphone, agent volume and mute, Live view layout, voice controls and connection settings, whether you accepted the camera and screen-sharing notice, and whether you closed the plans welcome dialog. We also keep a copy of your account settings (refreshed after 5 minutes) and your approximate region (refreshed after 24 hours, used to show the right consent options). These are saved when you use the feature they belong to; your region is saved when our in-app cookie banner or memory-consent dialog opens, before you make a choice. Your cookie choices do not stop them from being saved. Saving a cookie choice in the app without Functional deletes a saved theme; with Global Privacy Control (sent by this browser, or recorded on your account), this happens each time you open the app while logged in. Clearing site data removes them.
These optional technologies run only when Analytics is enabled:
We do not currently use advertising or remarketing trackers. The Marketing category is off by default and has no active trackers.

|---|---|---|---|---|
| refresh_token | Cookie (HttpOnly, Secure, sent only to our login addresses /v1/auth/) | Keeps you logged in | Your login ends a set number of days after you log in; the browser keeps the cookie for that long after each renewal; removed when server logout succeeds, otherwise it can remain until it expires or you clear site data | Essential |

These services run on our pages, or on pages we send you to, and may use their own cookies or browser storage:
Some live audio/video relay runs on infrastructure we host. Other providers process data on our servers or during connected features without necessarily setting a cookie in your browser. See the Privacy Policy's service list for what each receives and why. Analytics consent controls the optional browser monitoring and Google Analytics described above; it does not turn off processing needed for a feature you use.
Most of what we keep is in local storage and session storage, not cookies: login details, your cookie choice, settings, copies of your account settings and region (refreshed after 5 minutes and 24 hours, kept until you clear site data), and an id that resumes a Live conversation after a page reload (the conversation text is loaded from our servers). Logging out removes your stored login details (a random login marker stays). The login cookie is removed when server logout succeeds; otherwise it can remain until it expires or you clear site data. Session storage items are deleted when you close the tab; everything else, including your selected organization and the copy of your account settings, stays until you clear site data for our website.
You can control and manage cookies in several ways:
Note: Blocking cookies or site data for our website may log you out or stop the Service from working properly.
To manage cookies and site data in your browser:
When your browser sends a Global Privacy Control signal (or the opt-out is recorded on your account), we save your optional cookie categories as off and disable Analytics. Other settings described in section 2.2 can still be saved.
We may update this Cookie Policy from time to time to reflect changes in our practices or for operational, legal, or regulatory reasons. The updated policy will be posted on this page with a new "Last Updated" date.
