Every connection is intentional—no accidents, no strangers, no surprises.
Your existing contacts are imported with full encryption—we never see the raw data.
Manual verification ensures every connection is intentional. No algorithmic suggestions, ever.
Your fortress walls are up. Untrusted contacts simply cannot reach you—no blocking required.
