ZenView for YouTube — Privacy policy

Last updated: November 12, 2026

Summary

ZenView for YouTube does not collect, sell or transmit any personal data. There is no account, no advertising and no analytics.

Data stored on your computer

The extension only stores, in Chrome's local storage (chrome.storage.local):

• your settings and chosen profile (Teacher or Personal);
• the counter of ads avoided and time saved;
• the playback position of the last 200 videos, for resuming;
• the clips (start, end, loop) you set for a video;
• the extension's health state (automatic pause).

This data never leaves your computer and is deleted when you uninstall the extension.

SponsorBlock (off by default)

If you turn on skipping of sponsored segments, the extension queries the public SponsorBlock service (sponsor.ajay.app) sending only the first 4 characters of the SHA-256 hash of the video ID, so the service cannot tell which video you are watching. Nothing else is sent.

Publisher
