PSippr
A dating and social app with no server behind it.
Your profile, photos and messages never touch a cloud. They travel straight between devices, encrypted end to end. There is no account, no e-mail, no phone number — your profile is your identity, and it lives on your phone.
What it does
- Nearby — a grid of people around you, closest first, with live online status. Distance comes from a coarse geohash, never from exact coordinates.
- Chat — end-to-end encrypted messages, photos, videos and voice notes, delivered directly to the other device.
- Calls — one-to-one and group video calls that connect peer to peer, even between two phones on mobile networks, without any relay service in the middle.
- Albums — photo and video albums you share with whom you choose, including locked adult albums that stay blurred until you grant access.
- Public feed — a global timeline of posts from people around you, with link previews and reactions.
- Places — points of interest around you and who is currently there.
- Hearts — a mutual-interest handshake: an outline heart becomes solid only when the interest goes both ways.
Why serverless
Ordinary apps keep your photos, messages and location on their servers. PSippr has no servers at all, so:
- there is no database that can leak, be sold, or be handed over,
- nobody can read your messages, because they never leave the two devices,
- the app keeps working on a local network even with the internet down,
- shutting the project down cannot take your data with it — it is already yours, on your device.
Peers find each other over the local network and over a public peer-to-peer network. The only thing published about you is a small signed announcement (nickname, coarse area, online status) that anyone in range would see in the app anyway.
Security
- Every announcement is cryptographically signed, so nobody can pretend to be you.
- The 18+ check is local — your date of birth never leaves the device.
- Adult-content detection runs on the device; photos are never uploaded for moderation.
- Screenshots are blocked inside the app on Android.
- Optional biometric lock protects the app with your fingerprint or face.
- Backup and restore produce a single zip file that only you hold.
Platforms
Android and desktop (Linux, Windows). The iOS build is in preparation. The app updates itself — when a new version is out, it offers the update on the spot.
Get the app
PSippr is distributed outside the app stores, directly by its author. Write to mimoccc@gmail.com for the current build.
The app is strictly for adults (18+).
Paid features
The app is free. Three optional features cost 5 € per month each: multi-person video chat, custom albums and a bonus pack (incognito mode and more). Payments go through Stripe payment pages — the app never sees your card details. Details are in the user guide.
