Like a night deposit box: every message is a sealed envelope, dropped for one person only, opened by no one in between.\n\n* Anonymous identities only — no phone number, no email, no account. Your identity is a keypair held on your device.\n* End-to-end encryption with the Signal Double Ratchet: only the sender and receiver can read a message.\n* Peer-to-peer over Tor by default. There is no clearnet path — the only network egress is the Tor network.\n* Local-first storage: messages live on your device. Optional server storage is opt-in, capped at 24 hours, and shows a persistent warning in the chat while active.\n* An untrusted store-and-forward relay carries offline delivery only. Any relay ever holds nothing but opaque, already-encrypted blobs under unlinkable handles — no keys, no plaintext, no identities, no logs.\n* Authorization before the first message: a stranger cannot message you until you approve them (scan a pre-authorized QR, or exchange a short code whose secret words block a man-in-the-middle).\n* Safety-number verification (scan or compare) to confirm no one is in the middle.\n* User-owned encrypted backups: the recovery password is generated on your device, shown once, and never sent to any server. Lose it and the backup is unrecoverable — by design.\n* No analytics, no crash reporters, no ad SDKs, no Google Play Services, and no third-party push service.\n* No automatic update check on F-Droid installs. Other builds (sideloaded, or the desktop AppImage, which have no update channel of their own) ask the Night Drop onion site over Tor, at most once a day, whether a newer version exists — and only tell you. The app never installs anything, and does not hold the permission that would let it.\n\nNight Drop is free software (AGPL-3.0-or-later) and built to be reproducible: anyone can rebuild the release from source and confirm it matches, byte for byte.\n","categories":["Messaging"]}
