What an encrypted photo backup should prove
A file can be written without being uploaded, verified or restorable. Learn to treat those as separate facts.
Encrypted Library & BackupsNo account, advertising, analytics or behavioural tracking.
No vague promises
A clearer way to decide
Photress is a private, encrypted photo and video library designed to keep your files under your control. Your media stays on your iPhone and in backup locations you choose. No Photress account is required.
Use these steps as a decision framework rather than a promise that one storage choice removes every risk.
You can see each step separately: whether the backup was written, uploaded to your chosen storage, passed an integrity check, and passed a restore test.
Open a portable backup with a Backup Passphrase you create or an independent 24-word Recovery Key.
Original photo and video resources, thumbnails, library metadata, and local indexes are encrypted at rest.
Every media resource gets its own random 256-bit key. AES-256-GCM encrypts and authenticates the data, so altered or corrupted encrypted content is rejected.
What matters here
Details that should not stay hidden
A file can be written without being uploaded, verified or restorable. Learn to treat those as separate facts.
Good privacy software should make the state understandable before asking you to trust it.
Metadata uses a separately keyed SQLCipher database. Backup Passphrases use Argon2id, while the local App Code is deliberately excluded from portable-backup encryption.

What Photress promises — and what it does not
Photress reports only the evidence it has. It does not turn a local write into a cloud-upload claim or a successful integrity check into a completed restore test.
Before you continue
Keep at least one portable backup credential outside the iPhone, retain access to the chosen destination and verify important copies periodically.
