Privacy Policy
Last updated: 2026-07-01
The short version
NovaBlock is designed to not collect personal data. We don't track your browsing, we don't sell data, and we don't build advertising profiles. Filtering runs locally inside the Chrome extension using Manifest V3.
What the extension does
- Loads filter lists locally and blocks ads, trackers, pop-ups, cookie banners and YouTube pre-rolls.
- Stores a random anonymous device token in browser storage so Premium can be tied to your install.
- Counts blocked requests locally so the popup can show stats. Counts never leave your device.
What the extension does not do
- It does not send your browsing history to us or anyone else.
- It does not read or share form input, cookies or page content.
- It does not contain third-party analytics or advertising SDKs.
Analytics
If you opt in, we use Cloudflare Web Analytics, cookieless and anonymous, to understand aggregate usage. It's off by default.
Crash reports
If you opt in, we use Sentry to collect anonymized crash logs and error reports so we can fix bugs faster. No browsing history or personal content is included. It's off by default.
Premium and payments
Payments are processed by Stripe. When you purchase Premium, Stripe collects your billing details under its privacy policy. We receive a customer id, subscription id and email from Stripe so we can activate your license. We store this in a database protected by row-level security and access it only to activate, renew or deactivate Premium, reply to support requests, and prevent fraud.
Support messages
If you write to us through the contact form, we keep your message and email so we can reply.
Your rights
You can request a copy or deletion of any data tied to your email by writing to privacy@novablock.app.
Children
NovaBlock is not directed at children under 13.
