We built Blockzeee on a single principle: your data is none of our business. Here's exactly what that means.
The short version: Blockzeee collects zero personal data, transmits nothing to any server, and never has. This policy exists to be transparent about that fact — not to bury what we collect in fine print.
Blockzeee ("the extension," "we," "us") is a browser extension available for Chrome, Firefox, Safari, Edge, Opera, and Brave. Its sole purpose is to block ads, trackers, and fingerprinting scripts locally on your device using declarativeNetRequest rules and content scripts.
This Privacy Policy describes our data practices. If you have questions, contact us at the address in Section 8.
Blockzeee collects no personal data whatsoever. Specifically:
All extension state (enabled/disabled toggle, settings preferences) is stored exclusively in your browser's local storage using the standard chrome.storage.local API. This data never leaves your device and is not accessible to us.
Blockzeee operates entirely on-device using two mechanisms:
No outbound network requests are made by the extension itself. There are no update servers, no license check endpoints, and no telemetry endpoints.
The extension requests the following permissions and uses them as described:
Blockzeee does not integrate with any third-party analytics, advertising, or data-sharing services. We use no SDKs, no tracking pixels, and no external APIs.
The extension is distributed through browser extension stores (Chrome Web Store, Firefox Add-ons, etc.). Those stores have their own privacy policies governing your relationship with them as a platform; Blockzeee has no control over or responsibility for those policies.
Blockzeee does not collect any data from any user, including children under the age of 13. Because we collect no personal information, the extension is compliant with COPPA by default. We do not knowingly direct the extension at children as a primary audience.
If we ever change this policy in a material way, we will update the "Last updated" date at the top of this page and, where required by platform policies, notify users through the extension's store listing. The current version of this policy is always available at the URL where you are reading it.
Because we collect no data today, any material change would represent an expansion of data collection — and we are committed to never doing that without explicit, informed user consent.

In compliance with the Chrome Web Store Developer Program Policies, this section formally discloses how Blockzeee handles user data obtained through Chrome APIs.
Blockzeee's use of information received from Chrome APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements. Specifically:
All data accessed by Blockzeee (tab URLs, page DOM structure) is used only for its core function: blocking ads and trackers on the current page. This data is processed in memory, never stored to disk, never transmitted, and discarded when the tab closes.
Blockzeee will not use or transfer user data for purposes unrelated to the extension's single, stated purpose: blocking advertisements, trackers, and fingerprinting scripts in the user's browser.
Blockzeee will not use or transfer user data to determine creditworthiness or for lending purposes.
Blockzeee will not sell user data to third parties.
Blockzeee will not use or transfer user data for personalized advertising.
These commitments apply permanently and are not subject to future change without explicit, prominent disclosure and user consent.
