Your photos. Truly private.
Arca is a private vault for photos and videos with no server, no account, and no tracking. Everything is encrypted on your device with AES-256 — nothing ever leaves your phone, and nobody (including us) can see your photos. Ever.
WHY ARCA IS DIFFERENT
Most "photo vault" apps advertise military-grade encryption while quietly storing your photos unprotected. Arca was built the opposite way:
• Real AES-256 encryption — every photo, video, and thumbnail is individually encrypted, with keys protected by the Secure Enclave
• Zero knowledge — no server, no account, no cloud. There is nothing to hack and nothing to leak
• Your data is never trapped — export your original photos losslessly anytime, free
• Encrypted backup — save a single encrypted backup file to Files or iCloud Drive that only your PIN can open
• No lock-out dark patterns — your imported photos always stay accessible
PROTECT WHAT MATTERS
• Hide private photos and videos behind a 6-digit PIN and Face ID
• Private camera shoots straight into the vault, bypassing your camera roll
• Albums, favorites, and a fast, beautiful gallery
• ID cards, documents, licenses — keep them off your camera roll
SERIOUS SECURITY FEATURES
• Decoy vault — a second PIN opens a separate, innocent vault
• Break-in report — see when someone tried (and failed) to get in, with photo evidence
• Disguised app icon
• Auto-lock and privacy shield in the app switcher
• Strip location data when sharing
ARCA PREMIUM
Unlimited items, decoy vault, break-in report, encrypted backup, and disguised icons. Annual or pay-once lifetime. Your photos are never held hostage — exports stay free forever.
Arca means strongbox. Your photos deserve one.
