Privacy Policy

Last updated: 8 October 2026

1. What the extension does

Blur Opposite Gender is a browser extension that detects people in YouTube videos, Shorts and thumbnails and blurs them according to your settings. Detection is performed by an AI model that is bundled inside the extension and runs locally in your browser.

2. Data processed on your device

• Video frames and thumbnails shown on YouTube are analysed in memory on your computer. They are never uploaded to us or to anyone else, and are not saved.
• Thumbnail images are downloaded directly from YouTube's own image servers (ytimg.com) by the extension in order to analyse them — the same images YouTube already shows you.

3. Data stored by the extension

• Your settings (for example who to blur and blur strength) are saved with Chrome's built-in storage. If you are signed in to Chrome, Chrome may sync these settings between your devices through your Google account.
• A speed measurement (milliseconds per check) is stored locally so the settings panel can show it.
• Results for thumbnails already checked are kept on your own computer so the same cover is never analysed twice. This is a local cache only — it is never sent anywhere, and clearing your browsing data removes it.

The extension does not use cookies, analytics, advertising or tracking of any kind, and does not read your browsing history.

4. Free trial and plan check

To give every new install its free trial, and to know whether your subscription is active, the extension contacts our server when it is installed and then about every few hours. It sends only:

• A random install ID created by the extension. It is not linked to your name, your Google account or anything you watch.
• A device label such as “Chrome on Windows”, so you can tell your computers apart in your account.

Our server also sees your IP address as part of the connection. We do not store it; we store only a one-way scrambled (hashed) form of it, used to stop the same network from creating large numbers of free trials. We keep when the install was first and last seen and when its trial ends.

5. Your account, payments and subscription

You do not need an account for the free plan or the trial. If you subscribe, you sign in with your email address and a one-time code we email to you; there is no password. We keep your email address, the computers (install IDs) linked to your account, your plan, its status and its renewal date, and a record of each payment (amount, date and the payment provider's reference).

Payments are processed by our payment provider. It collects the details needed to take payment and calculate tax (such as your name, email address, country and payment method) under its own privacy policy. Your card details are entered on the provider's secure checkout and are never received or stored by us. We use your email only for sign-in codes, receipts and support. Our account and database service is Supabase, which stores this data on our behalf.

6. Sharing

We do not sell, rent or share your personal information. Payment data is handled only by our payment provider, under its own privacy policy. Supabase stores account data for us and may not use it for anything else.

7. Keeping and deleting your data

We keep account and payment records for as long as your account exists and as required for tax and accounting. To delete your account, email us from the address you signed in with and we will remove your email and linked install IDs. Uninstalling the extension removes everything it stored on your computer.

8. Permissions the extension asks for

• Access to youtube.com and ytimg.com — to detect and blur people on YouTube pages and to load thumbnails for analysis.
• Storage — to remember your settings.
• Scripting — to reactivate blurring on already-open YouTube tabs after the extension updates.

9. Children

The extension is not directed at children and we do not knowingly collect personal information from children.

10. Changes

If this policy changes, we will update the date at the top of this page.
