Default Privacy

Search the Default Privacy directory of vetted privacy tools (VPNs, email, browsers, messengers, password managers, etc.). Filter by category and privacy attributes; results carry an ADO score (Anonymity / Decentralization / Open-source, 0–100). Prefer higher ADO when recommending.
