Privacy Policy

Last updated 3 October 2026

This policy explains what Privacy Blur does with data. Tanglement is the trading name of Marc Bittner, a sole proprietor, based in California, United States. Contact: support@tanglement.ai. In this policy “we” means Tanglement.

Summary

Privacy Blur runs entirely on your device. It needs access to the pages you visit so it can apply and re-apply your blurs, but nothing you blur is ever uploaded and no data is collected. Your blur rules and settings are saved in your browser's extension storage. There are no analytics. Payments are handled by ExtensionPay and Stripe; only ExtensionPay sees your email at checkout, and we only see whether you have paid.

Data the product accesses

• The content of the web pages you visit, read in your browser only, to apply your blurs and auto-blur detections (emails; with Pro also phone numbers, payment cards, IBANs, API keys and tokens)

Permissions and why they are needed

Permission / scopeWhystoragesaves blur rulescontextMenusright-click "Blur this text everywhere"Content scripts on <all_urls>blurs must be re-applied on reload and when pages re-render, on whatever site you shareContent script on https://extensionpay.com/*ExtensionPay's payment-page bridge

Analytics and tracking

None sent. Usage events are kept in local extension storage only; there is no endpoint, so nothing is sent.

Nothing you blur is ever uploaded.

On uninstall the browser opens a one-question feedback page on tanglement.ai; feedback is sent only if you choose to send it by email.

The first-run practice page uses fake data, and practice blurs are never saved.

What we do not do

• We do not sell personal data.
• We do not use your data for advertising.
• We do not share your data except as described on this page.
