⚠ REQUIRES شما OWN SERVER. DeltaSync does nothing on its own. You must first install و run the self-hosted DeltaSync server (PHP + PostgreSQL), or have access to someone else's, و enrol this device against it. There is no public or default server — بدون one, this برنامه has nothing to همگامسازی و cannot even be set up. If you just want a standalone KeePass برنامه, this is not it: use KeePass2Android or KeePassDX instead. DeltaSync keeps a KeePass (.kdbx) database synchronised across دستگاه شماs through a server that only ever sees encrypted blobs. شما master رمز عبور never leaves the device, و the server cannot read entry titles, usernames, passwords, یادداشتها or attachments — even if it is compromised. How it differs from other KeePass همگامسازی solutions: • Entry-level deltas: only changed entries cross the wire, not the whole .kdbx file. Fewer bytes uploaded, fewer wholesale conflicts. • Real end-to-end encryption: per-entry XChaCha20-Poly1305 با a key derived from شما master رمز عبور via Argon2id و HKDF-SHA256. The server stores opaque ciphertext. • Concurrent edits merge: two devices editing different entries (or even different fields of the same entry) merge cleanly. Field-level last-writer-wins on conflicts. • Multi-user sharing بدون key escrow: NaCl sealed-box wraps the database master key to each recipient's device public key. The server sees who has access, not what they can decrypt. • متنباز from end to end: the AGPL-3.0 server (PHP/PostgreSQL), GPL-3.0 desktop client (Go), و this GPL-3.0 Android client are همه published. You can self-host the server, or use someone else's. This برنامه pairs با KeePass2Android or KeePassDX as شما editor — DeltaSync itself is a background همگامسازی service و does not display شما passwords. You point it at a .kdbx file on the device, supply the master رمز عبور once, و it keeps the file in همگامسازی با the server through WorkManager. Project: https://gitlab.com/Star95/keepass-deltasync Website: https://deltasync.bjoerck-braun.dk Groups همگامسازی too: group structure و which group each entry belongs to stay in همگامسازی across devices, alongside the entry contents. Status: v0.4 — the همگامسازی layer (entries + groups) is feature-complete و tested; the UI is functional but still minimal. Treat as beta.
