What the extension reads, sends, and keeps.

The Worthwatch extension does one thing. It gives a verdict on the video you are watching. Here is everything it touches to do that. The extension is published by NexusMKTG.com, LLC, Boston, Massachusetts.

One purpose.

On a video page, when you click the Worthwatch chip, the extension reads the video's captions and shows a verdict: watch, skim, or skip. Under it, what the video covers, where it starts, and what to skip. On any other site it does nothing. Before you click, it reads the video id and notes the player's own caption requests, and nothing else. After you agree to its first notice, it checks once per video whether a verdict already exists, which sends the video id. Nothing else is sent until you click.

What it reads, in your browser.

The video's caption track, the same one the player uses for subtitles. The video id, title, channel name, length, and category from the page. Whether the page is in dark or light theme, to match it. It reads nothing from other tabs, nothing from your history, nothing from your YouTube account, and no cookies.

What it sends to our server.

The caption text with its times, the video id, the title, the channel name, the length, the category, and the caption language. The first time, it asks you before sending anything. If you are signed in, it sends a session token so Pro features work. If you are not, it sends a random install id so your 5 free verdicts a day can be counted. The id identifies the install, not you, and carries nothing about you or your device. Nothing is sent to anyone but our server, and our server never asks YouTube for anything as you or with your account.

What is kept.

The verdict, by video id, in a shared cache with nothing personal attached. Your session token or install id, in the extension's own storage on your computer, and the install id with its daily count on our server. Your settings from the options page. The captions are analyzed and discarded. They are kept only when you save a verdict on a Pro account, in your library, until you remove it.

The permissions, and why each one.

Who else sees the captions.

Our server sends the captions and the title to a model provider to produce the verdict. The request carries no account information. The provider in use is named on the How it works page, and its published API terms, as of the date at the top of this page, state that customer data is not used to train its models. Nothing is used to train a model.

Your choices.

Turn the extension off or remove it from the Chrome extensions page at any time. Sign out from the options page to revoke the session token. Delete your account from the account page to remove everything tied to it. Worthwatch is for people 13 and older. Questions go to brett@nexusmktg.com. Worthwatch is independent and not affiliated with YouTube or Google.
