Not For You is a browser extension developed by SIDANE LLC ("we", "us", "our"). This Privacy Policy explains what data we collect, why, and how we handle it.
Email address — collected only when you subscribe to the Pro plan or restore a subscription. Your email is used to:
Device identifier — a randomly generated UUID stored locally on your device, used to enforce the 4-device limit for Pro subscribers. This identifier is not linked to your identity and cannot be used to track you.
Basic device info — browser name and operating system (e.g. "Chrome on macOS"), collected only for Pro subscribers to display in the device management screen.
Your preferences (enabled/disabled, selected site, block statistics) are stored locally in your browser using the extension's storage API. This data never leaves your device.
For Pro subscribers, your email and subscription status are stored in our Supabase database (hosted in the EU, region eu-west-1). Payment is processed by Stripe — we never see or store your credit card information.
We do not use any analytics, advertising, or tracking services.
We do not sell, trade, or share your personal data with third parties, except as required by law or as described above (Stripe for payment, Supabase for authentication).
Your email and subscription data are retained as long as your subscription is active. If you cancel, your data is kept for 30 days after the subscription period ends, then deleted.
You can request deletion of your data at any time by contacting us at contact@sidane.org. We will process your request within 30 days.
Not For You is not directed at children under 13. We do not knowingly collect personal data from children.
We may update this policy from time to time. Changes will be posted on this page with an updated date. Continued use of the extension after changes constitutes acceptance.
