Where Kistvault is different
- Stronger unlock. A password or pattern stretched by Argon2id, rather than a short PIN as the primary gate.
- A real recovery path. A printed Recovery Kit that opens the vault on a clean device — not just a PIN you mustn't forget.
- Truly local, portable vault. No cloud, and a byte-exact container that moves between iOS and Android.
- Documents too, not only photos and videos.
Where Private Photo Vault shines
Private Photo Vault is popular for good reasons: it's simple, familiar, and ships crowd-pleasing extras like decoy PINs and break-in alerts, with an easy on-ramp for anyone who just wants photos behind a PIN. If a lightweight, friendly photo locker is all you need, it does that job.
Bottom line: Private Photo Vault is a friendly PIN locker for photos. Kistvault is a zero-knowledge vault — Argon2id, no cloud, cross-platform, and recoverable by a Kit you hold — for files you truly can't afford to lose or leak.
