Privacy Policy — THCOS
Chrome extension · last updated 26 August 2026
THCOS — The Company OS — tells you when one of your videos is waiting for your browser, and puts your workspaces one click away. This policy covers the extension only. It is deliberately specific: rather than reserving rights we do not use, it lists exactly what the extension reads and stores, because that list is short.
The extension has no server of its own. It talks to
app.thcos.com and to nothing else. There is no analytics, no telemetry, no
tracking, no advertising, and no third-party service of any kind.
What it reads
Two endpoints on app.thcos.com, using the session cookie already in your browser
from signing in there. The extension never sees, handles, or stores your password.
/api/browser-tasks— whether any finished video is waiting for a browser to turn it into a playable file, and which workspace it belongs to./api/workspaces— the names, emoji and ids of your own workspaces, so the panel can list them and open one.
It also creates a workspace on app.thcos.com when you press + New
in the panel, which is a normal action on your own account.
What it stores
One object in Chrome's local extension storage, on your machine, overwritten on each check: whether you appear signed in, how many videos are waiting, the workspace name and id for each, and the time of the check.
It is kept for a single reason: to tell a newly waiting video from one that has been waiting for hours, so you get one notification instead of a repeat every five minutes. It never leaves your device. Removing the extension removes it.
What it never does
- No content scripts. It cannot read, alter, or see any web page you visit — including THCOS itself.
- No browsing data. It does not read your history, your tabs, your other sites, your bookmarks, or your form data.
- No sale or transfer. Nothing is sold, rented, shared, or transferred to anyone. There is nobody to transfer it to.
- Not used for anything else. Not for advertising, not for profiling, not for training any model, and not for any purpose unrelated to the single feature above.
- No remote code. Nothing is downloaded and executed. All of the extension's code ships inside the package Chrome reviews.
Permissions, and why each one exists
alarms— schedules the five-minute check. Chrome shuts an idle extension down, so an ordinary timer would not survive; without this it would simply stop working.notifications— tells you once, when a video starts waiting for your browser.storage— holds the single object described above.https://app.thcos.com/*— the only host it may contact. It cannot reach any other site.
The THCOS service itself
The extension is a window onto an account you already have. Data you create inside THCOS is handled by the THCOS service under its own terms; the extension neither adds to that nor changes it.
Removing it
Uninstalling the extension from chrome://extensions deletes its stored object and
ends all access immediately. Your THCOS account is unaffected.
Changes
If what the extension reads or stores ever changes, this page changes in the same release, and the date at the top moves. It is not a document that gets written once and left behind.
