Incognito Mode: What It Actually Does (and Doesn't Do)
2025-10-28 5 min read
Incognito doesn't make you anonymous — it just doesn't save your history locally. Learn exactly what private browsing does and doesn't protect you from.
"Just use incognito mode" — advice given to people who want privacy online. But incognito mode does far less than most people assume. Here's the honest, technical explanation of exactly what private browsing does and doesn't protect.
What Incognito Mode Actually Does
- Doesn't save your browsing history on your device
- Doesn't save cookies after the session ends (you'll be logged out of everything when you close the window)
- Doesn't save form inputs or searches in autocomplete
- Starts with a fresh cookie state (useful for testing logged-out experiences)
What Incognito Mode Does NOT Do
- Doesn't hide from your ISP: Your internet provider sees every domain you visit
- Doesn't hide from employer/school: If you're on a corporate or school network, IT can see your traffic
- Doesn't hide from websites: The sites you visit know your IP address and can fingerprint your browser
- Doesn't hide from Google: If you're signed in to Google in an incognito tab, Google tracks that session
- Doesn't block tracking pixels: Email pixels, third-party trackers on websites still load and fire
The Google Lawsuit (2022–2024)
Google settled a class-action lawsuit in 2024 over misleading users about incognito privacy. The case found that Google collected user data even in incognito mode through Analytics, Ads, and other embedded trackers. The settlement required Google to improve disclosures.
If You Actually Need Privacy
- VPN: Hides your traffic from ISP and local network (but not from the VPN provider)
- Tor Browser: Routes traffic through multiple nodes — much slower but genuinely anonymous
- Browser-based tools: Tools that process data locally (like Tools OP) don't send your files anywhere
