Do my ip-address, sites-i-visited, date/time of visit, geo-location ever gets stored in on a server outside (eg outside my phone or my computer I am browsing on)?
None of those get stored or even sent, except of course for IP address.
IP address is not yet masked for update pings (same as for all self-updating browsers, required for security patching) and for similar pings to check for updated ad/tracker blocklists. If you do not opt into any BAT ecosystem features (contributions or ads, which enables contributions), then your IP address is not otherwise used, but it does show up in our logs. See https://brave.com/privacy/ under "Technical Infrastructure".
(We'd like to do the update ping via Tor since we have Tor tabs already, but this is in the future.)
If you opt into BAT features and take free BAT grants from us, then IP address and a wallet identifier are used for antifraud purposes, but not otherwise. This is covered in the privacy policy at https://brave.com/privacy/ under "Payments".
