PSippr
A peer-to-peer social network for everything nearby — people, businesses, doctors, lawyers, cinemas, food, taxis and emergency help — that keeps your data on your phone: no cloud, no account, no database of users.
Your profile, photos and messages never touch a cloud. They travel between devices encrypted end to end — and when two phones cannot reach each other directly, a relay forwards the encrypted packets without being able to read them. There is no account, no e-mail, no phone number — your profile is your identity, and it lives on your phone.
PSippr is not a dating app. The heart button and preferences are just one of many features alongside businesses, doctors, jobs, rides and emergency help — not the whole point of the app.
Try it
The app is currently in a testing (RC) phase, not yet in any app store — a proper Google Play and App Store release will follow once every part of the app has been fully tested, planned within weeks (a month at most). A public audit of every part and component of the app is also being prepared before that store release. The app runs on all of these platforms — tap one and ask for a test build:
Download
- Android — Download PSippr.apk
- iPhone / iPad — Join the TestFlight beta (install the free TestFlight app from the App Store first)
- Linux — PSippr.deb · PSippr.rpm · PSippr.AppImage
- Windows — Download PSippr.exe
- Command line — PSippr-cli.zip: a headless node for a server or a Raspberry Pi (Linux, macOS, Windows, needs Java 17).

Every release lands here automatically. macOS is available on request — tap a platform above and ask for a build.

What it does
- Nearby — a grid of people around you, closest first, with live online status, star ratings, verified badges and a NEW tag for fresh profiles. Distance comes from a coarse geohash, never from exact coordinates.
- Profiles — a self-playing gallery of photos and short videos, a "now playing" music bubble with album art and your own private note on every person. The approximate map position and the taxi ride to a match are part of the bonus pack.
- Hearts — a mutual-interest handshake: an outline heart becomes solid only when the interest goes both ways. You can require mutual hearts for chat; calls always need them.
- Chat — end-to-end encrypted messages, photos, videos, GIFs, voice notes and albums, with threaded replies, reactions and delivery ticks. A phone number in a message gets instant call / save-contact actions.
- Calls — one-to-one and group video calls, encrypted end to end. The connection is negotiated with a Google STUN server and runs directly between the phones whenever the networks allow it; otherwise the encrypted stream is forwarded by a relay.
- Albums — photo and video albums you share with whom you choose, including locked adult albums that stay blurred until you grant access.
- Wall — a 24-hour timeline of posts from people around you, with link previews, likes and reactions, spreading from device to device.
- Private timeline — posts only for followers you approve yourself; they never spread around, every follower fetches them directly from you and gets notified about each new one.
- Video chats — see who is live in a group video chat right now and start your own with one tap.
- Places — points of interest around you and who is currently there.
- Groups — small contact groups with invites.
- Businesses, restaurants, doctors and lawyers — venues around you with their own profile: photos, address with navigation, opening hours, products with prices. Your device verifies the business against the company register by its ID (CZ, SK); an unverified business is clearly marked in the app. Doctors, lawyers and hospitals get their own category in the Nearby grid.
- Guides — hotels, restaurants, parties and private venues nearby by category, from a web search scoped to your city.
- Jobs — job offers and service requests nearby, with your own listing and an expiry date.
- Movies — shared movie and show links on the wall, with search.
- Emergency help and Lost & found — a public board of listings with text and a photo, tap to open the poster's profile.
- Resource usage — a live chart of CPU, memory and daily data/battery use right inside the app.
- Pick your own tabs — show only the tabs you use; turn the rest on in Settings whenever you want.
- Cart and orders — a separate cart for every business, kept on your device. A binding order goes to the business as a message, the business replies with a receipt and a payment link (Revolut), and once paid the order is flagged as Paid. The Orders tab lists them — new, done, cancelled.
- Ride sharing — ride requests around you and driver offers, paid via Revolut or Stripe.
- Share like a messenger — your chats show up directly in the system share sheet, and saved contacts get Message / Video call actions right in your address book.
- Multi-device — clone or move your profile between phone, tablet and desktop; devices keep each other in sync in the background.
- Star rating — five stars computed from the likes people give you, with a loyalty bonus for coming back daily.
- Anti-spam — community reports, moderator verdicts and a honeypot that catches fresh accounts mass-messaging the same text. Offenders end up seeing and talking only to moderators.
- Backup — your whole world in a single file that only you hold; restore it on any device (moderator feature; everyone can clone or move a profile between devices).

Why no cloud
Ordinary apps keep your photos, messages and location on their servers. PSippr stores nothing about you on any server, so:
- there is no database that can leak, be sold, or be handed over,
- nobody can read your messages — they are encrypted end to end, and a relay that forwards them sees only encrypted packets,
- 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, over a public peer-to-peer network (a gossip room for your coarse area, with address records and a small table of entry points on psippr.org, run by the author inside the EU). The only thing published about you is a small signed announcement — nickname, coarse area, online status, age, height, weight, preferences, what you are looking for and what you are listening to — the same things other users see on your card in the app. The privacy policy lists every field and every service involved.
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, desktop (Linux, Windows) and a command-line node without a screen. 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 psippr@psippr.org for the current build.
The app is strictly for adults (18+).
Paid features
The app is free. Four optional features cost 5 € per month each: multi-person video chat, custom albums, a bonus pack (incognito mode, map and taxi to a match, backup and more) and a business profile for venues. Payments go through Stripe payment pages — the app never sees your card details. Details are in the user guide.
