Audit whether your active session is running inside a Private or Incognito tab with our free Incognito Detector. Evaluate StorageManager quota limits, FileSystem API access blocks, and IndexedDB sandbox states directly inside your browser with complete privacy.
Open the tool to trigger automatic storage quota and sandbox checks.
Review the visual shield verdict card (Private / Incognito vs Standard Tab).
Examine storage quota values, FileSystem permissions, and IndexedDB status.
Evaluates StorageManager quota caps, FileSystem access, and IndexedDB error callbacks in parallel.
Helps users verify if their current browser window enforces private browsing isolation guarantees.
All sandbox scans run in local browser memory. Zero session data is transmitted to external servers.
Private Browsing (Incognito) mode isolates browsing sessions by preventing disk persistence of cookies, browsing history, and site cache.
To enforce non-persistence, browser engines clamp navigator.storage.estimate() quota ceilings (often capping available RAM-backed storage below 1200MB) and disable permanent FileSystem APIs.
Cross-referencing multiple storage API behaviors allows client-side scripts to verify whether private session sandboxing is active without requiring server network calls.
