Privacy Policy

Last updated: December 7, 2025

The short version: Prewatchr doesn't collect your personal data, doesn't track what you watch, and doesn't require an account. The only thing stored is a summary count — and it lives in your browser, not our servers.

What Prewatchr does

Prewatchr is a browser extension for Chrome and Firefox that generates AI-powered summaries of YouTube videos so you can decide whether to watch them — before you click.

What data we handle

Data	Where it goes	How long
Summaries count	Your browser only	Until you uninstall
Video URL (when you request a summary)	Processed, then deleted	Seconds
Video transcript	Processed, then deleted	Seconds
Your browsing history	Never collected	—
Personal information	Never collected	—

Stored locally on your device

The extension stores one piece of information in your browser's local storage:

The number of summaries you've generated

This data never leaves your device and is never transmitted to us.

What happens when you request a summary

When you click a YouTube thumbnail with Prewatchr armed, here's exactly what happens:

The video URL is sent to our server
The transcript is fetched from YouTube
The transcript is passed to an AI model to generate a summary
The summary is returned to your browser
All data is immediately discarded — nothing is stored on our end

What we do not do

Store your browsing history
Track which videos you watch
Collect personal information
Require login or accounts
Share data for marketing or advertising
Sell your data to third parties

Third-party services

To deliver the summary, we use the following services. Each has its own privacy policy:

Google Gemini AI

Generates the summary from the video transcript. View Gemini privacy terms →

YouTube / Google

Source of video transcripts and captions. View Google privacy policy →

Infrastructure providers

We use third-party services to ensure reliable delivery of transcripts. These services process video URLs temporarily during the summary request. No user data is stored or shared beyond real-time processing.

Data security

All communication between the extension and our server uses HTTPS encryption
Video data is processed in real-time only — no persistent storage
No user accounts or passwords are required or stored
Local statistics remain only in your browser

Your control

You have full control over your data:

Clear all local data at any time by uninstalling the extension
Stop using the service at any time — there's nothing to cancel
Request any information we might hold by contacting us below

Children's privacy

Prewatchr is not intended for use by children under the age of 13. We do not knowingly collect data from children.

Updates to this policy

We may update this privacy policy from time to time. When we do, the "Last updated" date at the top of this page will change. We recommend checking this page periodically.
