Arcus

Arcus is a password manager built on one simple promise: your secrets never leave your device. There are no accounts, no cloud, and no internet permission — Arcus literally cannot send your data anywhere. Everything you save is encrypted and stored only on your device. A DIFFERENT KIND OF LOCK Arcus is unlocked by more than a PIN. Its signature keypad captures your 4-digit PIN and the rhythm you tap it — a mix of short taps and long presses that only you know. Both together unlock your vault. Someone watching over your shoulder still doesn't have the pattern. WHAT YOU GET • Fully offline — no internet permission, no servers, no telemetry • No ads and no tracking • Strong encryption — AES-256 with an Argon2id-derived key, protected by your device's secure hardware • Built-in password generator with length and character controls • Organize entries into categories with custom icons and colors • Fast fuzzy search and quick filters • Passwords auto-hide after a moment; the clipboard clears itself after copying • Encrypted local backups you control, plus non-destructive sync between your own devices • Optimized two-pane layout on tablets and foldables • Available in English and Spanish PRIVACY BY DESIGN Arcus collects nothing and shares nothing. Secure screens block screenshots and screen recording. IMPORTANT — PLEASE READ Because only you can unlock your vault, your PIN and tap pattern cannot be recovered. If you forget them, your data cannot be restored — not by us, not by anyone. This is the price of true privacy. Keep an encrypted backup and remember your pattern. A one-time purchase. No subscriptions, no in-app purchases, no surprises.
