SafeMode is built with privacy-first architecture. We only receive anonymous content hashes - never the URLs you visit, browsing history, or personal information.
What Data We Collect
SafeMode operates almost entirely locally on your device. Here's exactly what happens with your data:

How Protection Works
SafeMode uses content-based detection that preserves your privacy:
Page content is hashed locally on your device using proprietary fuzzy hashing and visual hashing algorithms
Only anonymous hashes are sent to our servers for verification - never the URL or content itself
We cannot identify which websites you visit - we only see content fingerprints that match known threats
If you allow, URLs can be sent for triple verification - but never stored on our servers
No Tracking, No Ads
We do not track your browsing activity, sell your data, or show advertisements. SafeMode is funded by users who value privacy.
