Adblocker Zero Browser Extension — Privacy Policy
Effective date: August 11, 2026 · Applies to the Adblocker Zero extension for Chrome, Edge, Firefox and Safari, published by TechSmart.
Data the extension collects
None. Specifically, the extension has:
- No collection of browsing history or page content. The pages you visit are never recorded or sent anywhere.
- No personal or sensitive data collection — no names, emails, identifiers, health, financial, location or communication data of any kind.
- No telemetry, analytics or crash reporting inside the extension.
- No accounts and no identifiers that could link activity to you.
- No remote configuration or logging — we operate no servers that receive anything from the extension.
- No monetization of data — nothing is sold or shared with third parties, and there is no paid "acceptable ads" whitelisting program.
Data stored on your device only
Your settings — the on/off state, your trusted-sites list, your custom filters, and local blocked-request counters — are saved with the browser's extension storage on your device. They never leave it through us. If your browser syncs extension data between your own devices, that sync is performed by your browser vendor under its own privacy policy.
Network requests the extension makes
The extension's only network activity is downloading fresh copies of its public filter lists (EasyList, EasyPrivacy, Peter Lowe's list and the uBlock Origin lists) from raw.githubusercontent.com, where the Ghostery project publishes maintained mirrors. These are plain file downloads: no personal information, no identifiers and no cookies are sent with them. Like any web request, the server sees your IP address in order to deliver the file; GitHub's handling of requests is described in its own privacy statement.
Why the extension asks for its permissions
| Permission | Why it's needed |
|---|---|
| Access to all websites | Ads appear on every site, so the blocker must be allowed to filter requests and hide ad elements everywhere. Pages are read only to apply filters — nothing is recorded. |
| declarativeNetRequest | Lets the browser itself block ad and tracker requests natively (Chrome, Edge, Safari) without the extension seeing your traffic. |
| webRequest (Firefox) | Firefox's blocking mechanism: requests are matched against filter rules locally and blocked before they load. |
| storage | Saves your settings and cached filter lists on your device. |
| tabs / webNavigation | Detects which site is open so the per-site toggle and badge counter work. |
| alarms | Schedules the daily filter-list refresh. |
| scripting / userScripts | Injects the cosmetic-filtering styles and anti-adblock scriptlets into pages, locally. |
Store policy compliance
The extension's use of information complies with the Chrome Web Store User Data Policy, including its Limited Use requirements, and with the corresponding user-data policies of the Microsoft Edge Add-ons store, Mozilla Add-ons and the Apple App Store. Since the extension collects no user data at all, no data is used, transferred or disclosed for any purpose.
Children's privacy
The extension is not directed at children and collects no personal information from anyone, children included.
Changes to this policy
If the extension's data practices ever change, we will update this page and the effective date above, and describe the change in the release notes. Because it collects nothing, we expect changes to be rare.
