1Blocker
1Blocker is a Safari-focused content blocker for Apple devices that helps reduce ads, trackers, and page clutter while keeping filtering local.
What is 1Blocker?
1Blocker is a content-blocking and privacy app for Apple devices, published by the 1Blocker team and originally developed by Salavat Khanov and Rinat Khanov. On macOS, it integrates with Safari to block ads, trackers, cookie notices, social widgets, and other intrusive page elements before they load. The app uses Apple’s native content-blocking mechanisms, which is why users usually encounter it as a Safari extension and toolbar control rather than as a traditional always-open desktop app. It also supports custom rules, per-site allowances, and a blocking history view on Mac so users can review what was filtered. 1Blocker is primarily used by people who want a cleaner browsing experience, stronger privacy, and fewer distractions while using Safari. Because its filtering is designed to run locally on the device, it is generally regarded as a legitimate privacy utility rather than a data-harvesting browser add-on.

Safety overview
Status: Safe
1Blocker is a legitimate privacy and content-blocking app for Safari. Its core blocking functions are designed to work locally on the device, which reduces data-exposure risk compared with cloud-based filtering tools. As with any browser extension-style utility, it should be installed from trusted sources and reviewed if you no longer use Safari or no longer want web filtering.
Recommendation: Keep it if you use Safari and want ad blocking, tracker blocking, or fewer web annoyances. It is optional for users who do not use Safari regularly. If it is no longer needed, removing the app will disable its Safari-based filtering features.
