Private photos, hidden in plain sight
Hi-Filter keeps the photos you want to protect inside ordinary-looking ones — encrypted on your device, with no account and no server.
Encrypted on device
Your hidden photos are encrypted with AES-256-GCM using a key derived from a password only you know. Everything happens on your iPhone.
Nothing is uploaded
The app makes no network requests. There is no account to create and no server that could hold your photos.
Looks like a normal album
Hidden photos live inside cover images, so they appear as everyday pictures. Only you know which ones carry a secret.
Yours to keep
The full version is a one-time purchase. Restore Purchases brings it back after a reinstall or a new phone.
