Privacy Policy — SanityTV

Last updated: 2026-05-08

SanityTV is a Chrome extension that filters YouTube videos exploiting attention-engineering patterns (clickbait, rage-bait, sensationalism, brainrot, harmful kid content). This document explains exactly what SanityTV does and does not do with your data.

Short version

SanityTV does not collect, transmit, or sell any personal data.

Everything happens on your device. No telemetry. No analytics. No servers. No tracking pixels. No third-party SDKs. The extension’s entire source code is public on GitHub for anyone to audit.

What data SanityTV reads

The extension reads the titles, channel names and visible duration of YouTube videos that appear on pages you visit. It must read this data to score each video and decide whether to show, grey out, or hide it.

This happens entirely in your browser, in memory. The data is never sent anywhere, never written to disk, and never shared with us or any third party. The moment you close the tab, that data is gone.

What data SanityTV stores

SanityTV uses Chrome’s storage APIs to remember your settings on your device:

• Whether the filter is on or off
• Your sensitivity slider value
• Your channel whitelist and blacklist
• The “Hide all Shorts” toggle
• Counters of how many videos were hidden / greyed (your stats)

This data is stored in:

• chrome.storage.sync — settings (synced across your own Chrome profiles by Google, only between your own devices, only if you have Chrome Sync enabled)
• chrome.storage.local — counters and stats (kept on this device only)

We never see this data. It belongs to you and to Chrome’s storage infrastructure.

What data SanityTV does NOT do

• ❌ No data sent to any server (we don’t have one)
• ❌ No analytics, no telemetry, no crash reporting
• ❌ No ads, no monetisation, no affiliate links
• ❌ No third-party SDKs of any kind
• ❌ No reading of your YouTube account, watch history, or subscriptions
• ❌ No tracking across websites
• ❌ No collection of your IP address, location, or device identifiers
• ❌ No use of cookies (other than YouTube’s own that we do not touch)

Permissions and why we ask for them

Permission	Why
storage	Save your settings and stats locally on your device.
host_permissions for *://*.youtube.com/*	Inject the content script that reads page titles and decides which videos to filter. We do not request access to any other website.

That’s it. No tabs, no webRequest, no cookies, no clipboard, no downloads, no network access.

Children’s privacy

SanityTV is not designed for children and does not knowingly collect data from anyone, regardless of age. It is also not a parental control product — see our note on this.
