Privacy policy

Last updated October 15, 2026. Applies to the TubeStat browser extension and this website.

TubeStat keeps a record of your YouTube viewing on your own device. It has no server and no account. Your viewing history is never sent to the developer or anyone else, never sold, and never used for advertising.

What TubeStat records

Only while you use youtube.com in a browser where TubeStat is installed:

Videos you play: the video’s ID, title, channel name and channel ID, length, YouTube’s category for it, whether it’s a Short or a live stream, when you watched, how long it actually played, and how much of it you covered.
Channels you visit: name, handle, profile picture address, and public subscriber count, recorded at most once a day.
Your subscriptions: which channels you’re subscribed to, read from YouTube pages you open, and the date you subscribed when YouTube makes it available.
Your settings, and any friend groups and stat codes you add.

TubeStat does not record your searches, comments, likes, recommendations, messages, account details, or anything you do on any other website.

Where it’s stored

Everything is kept in your browser’s extension storage on this device. It isn’t synced to other devices or to any cloud service. Uninstalling TubeStat deletes it.

What leaves your device

Your viewing data never does. TubeStat makes only these network requests:

Images from YouTube’s servers (video thumbnails and channel pictures), to display them in your dashboard and draw share cards.
The YouTube Data API, only if you choose to connect your account. This is off by default. If you turn it on, TubeStat asks Google for read-only access to your subscriptions, reads your subscription list and those channels’ public statistics, and stores the results on your device. The access token is kept in memory only for that sync and is never saved. TubeStat’s use of information received from Google APIs follows the Google API Services User Data Policy, including its Limited Use requirements.

What friends see

Nothing, unless you share something yourself. A stat code contains your chosen name and this week’s totals (watch time, number of videos, number of creators, and streaks). It never contains video titles, channels, or history. Share cards are images created on your device that you download or copy yourself.

Your choices

Pause recording at any time under Tracking on the Profile page.
Export everything TubeStat has recorded as a JSON file under Your data on the Profile page.
Delete all of it with Delete everything on the Profile page, or by removing the extension.

Website

This website is hosted on GitHub Pages and loads fonts from Google Fonts. It has no analytics, cookies, or tracking of its own. GitHub and Google may log requests as described in their own privacy policies.

Children

TubeStat isn’t directed at children under 13 and doesn’t knowingly collect information about anyone. All data stays on the device where it was recorded.

Changes and contact

If this policy changes, the new version will be posted here with a new date. Questions or concerns: open an issue on the TubeStat GitHub repository.
