Your photo library, on your own computer.

Preen backs up your phone’s photos and videos to your computer, then shows everything — phone and computer — in one timeline on your phone. No cloud: your photos stay on your own devices.

iPhone · Android · macOS · Windows · Linux

Your phone and your computer connected directly, with an encrypted link and no server in between.direct · encryptedyour phoneyour computer
How it works

Set up in minutes. No server required.

No Docker, no NAS, no port forwarding. Install the desktop app, sign in on both devices, and you’re done.

  1. Install Preen on your computer

    Get the desktop app for macOS, Windows or Linux. Pick the folder or drive where your photos should live.

  2. Sign in on your phone and computer

    Install Preen on your iPhone or Android phone and sign in on both. They find each other on their own.

  3. Tap Back Up

    Your photos and videos copy to your computer, and your phone shows everything in one timeline.

Features

Everything you expect from a photo library.

Browse, search, edit and organize — with your photos stored on hardware you own.

  • One timeline

    Photos on your phone and photos that live only on your computer, together in one scrolling library on your phone.

  • Full-resolution originals

    Preen backs up the original files, not compressed copies — photos and videos alike.

  • Videos stream on demand

    Play a video stored on your computer without downloading the whole file to your phone first.

  • Search your photos

    Search by scenes, objects and places, or find photos with people in them. Photo analysis runs on your phone.

  • Map view

    See your photos on a map by where they were taken.

  • Photo editor with masks

    Adjust light and color, and apply changes to just part of a photo with masks.

  • Free up phone space

    Remove originals from your phone once they’re safely backed up. They stay in your timeline.

  • Delete from backups

    Remove a photo from your computers right from your phone. It’s deleted for good — there’s no trash.

  • A library for each person Preen+

    Family members each get their own library on the same computers, and see only their own photos in Preen.

  • Mirror to more drives

    Add a second drive and Preen keeps a copy on each. With Preen+, other computers you add keep a copy too.

Privacy

Your photos never live on our servers.

Preen connects your phone and your computer directly. We run the service that signs you in and introduces your devices to each other — your photos travel only between your own devices.

  • Encrypted, device to device

    Photos travel over a direct, encrypted connection (WebRTC) between your phone and your computer.

  • Not stored, not readable by us

    Your photos are never stored on our servers, and we have no way to read them.

  • Encrypted on your computer

    Your library is encrypted on your own drives. Only your phone or your recovery phrase can open it.

  • A relay only when needed

    If a direct path is impossible, Preen+ can use a relay that only passes along encrypted traffic.

  • Photo analysis runs on your phone

    Scene and people detection happen on your phone; place names may use your phone’s location service.

Why Preen

A photo library on your hardware, without the homework.

  • Self-hosted photo servers

    Usually mean setting up Docker or a server, and a VPN or port forwarding to reach your photos away from home.

  • File-sync apps

    Copy files to your computer, but don’t give you a photo library to browse, search and edit on your phone.

  • Preen

    An app on your computer, an app on your phone, one sign-in. You get a full photo library, and your photos stay on your own devices.

FAQ

Questions, answered.

Something else? Get in touch.

Are my photos uploaded to your servers?

No. Your photos go directly from your phone to your computer over an encrypted connection. They are never stored on our servers, and we can’t read them. Our servers handle your account and help your devices find each other.

What do I need?

An iPhone or Android phone, and a Mac, Windows or Linux computer with room for your photos. No Docker, no NAS, and no router or port-forwarding setup.

Does it work when I’m away from home?

The free version backs up and shows your full library when your phone and computer are on the same home Wi-Fi. With Preen+ you can back up and browse from anywhere.

What if my phone and computer can’t connect directly?

Preen always tries a direct connection first. When a direct path isn’t possible, Preen+ can fall back to a relay that only passes along encrypted traffic — it can’t see your photos and doesn’t store them.

What happens when my computer is off?

Photos still on your phone are always there. Photos that live only on your computer load again as soon as your computer is on and reachable.

Is it full quality?

Yes. Preen backs up the original files, including videos, at full resolution.

Can my family use it?

Yes, with Preen+. Each person gets their own library on the same computers. Each library is encrypted on the computer with that person’s own key, so other people using the computer can’t open it.

Are my photos encrypted on my computer?

Yes. Your library is encrypted on your computer and its drives. Your phone and your 24-word recovery phrase are the keys. If you lose both, we can’t recover your photos. Export makes a normal, readable copy whenever you want one.

What if a drive fails?

Add a second drive in the desktop app and Preen mirrors your library onto it. With Preen+, other computers you sign in on keep a copy too.
