NIFOBS Containers does not collect, transmit, sell, or share personal data with any external server. All profile data, container mappings, and settings are stored locally in the user’s browser storage. Cookie operations are performed only to provide profile isolation and restoration inside Firefox containers. The extension uses Firefox permissions (storage, tabs, cookies, contextualIdentities, webRequest, webRequestBlocking) strictly for core functionality. No analytics, tracking pixels, or remote telemetry are used.
