Privacy Policy

Last updated: 15 October 2026

Phasor is made by CelarTech. This policy explains what Phasor does with information, in plain words.

The short version: Phasor has no accounts, no ads, no analytics and no tracking. Your music and your listening stay on your phones. We do not collect your personal information, and we never sell anything about you.

What stays on your phone

Phasor reads the music and video files you choose so it can play them. They are not uploaded to us or to anyone else.

Your settings, playlists, liked songs and listening history are saved only on your phone. Uninstalling Phasor, or clearing its data, removes them.

Phasor keeps a random identifier for your phone, made when you first open it. It lets a room recognise your phone when you reconnect. It is not linked to your name, your Google or Apple account, or your phone number, and it is never sent to us.

What phones in a room share

When you open or join a room, the phones in it talk to each other directly over your Wi-Fi or hotspot. They share the audio being played, the song title and artist, your phone’s name (which you can change in Settings), and what is needed to keep them in sync.

This is encrypted between the phones, and none of it passes through a server of ours. There is no server: the room exists only on the phones in it, and ends when it ends.

A room’s code, shown when the host taps Invite phones, holds what another phone needs to reach the room: its name, the host phone’s name and local address and, when Phasor makes a Wi-Fi network for the room, that network’s name and password. It is shown on screen and never sent anywhere. Anyone who scans it can ask to join, and the host still decides who gets in. Joining a network Phasor made asks Android first, and lasts only while you are in the room.

Permissions and why Phasor asks

Nearby devices and local network: to find rooms near you and connect to them.

Music, audio and video: to list and play the files on your phone.

Notifications: to show what is playing and let you control it when the app is closed.

Scanning a room’s code uses Google’s code scanner, part of Google Play services, which reads the code on your phone. Phasor is not given the camera and receives only the text of the code.

On Android, Device Audio asks for audio capture and screen-sharing approval so it can share what another app is playing. Phasor uses this only for the audio of other apps. It does not record your microphone or your screen.

Microphone, for live voice: only when you tap Talk yourself, as the host or on a phone the host lets talk. Nobody can turn on your microphone for you. What it picks up is sent live, encrypted, to the phones in the room and played there. It is not recorded, kept or sent anywhere else, and it stops when you mute, when the host mutes you, or when the room ends.

You can say no to any of these. The parts of Phasor that need them will not work, and everything else will.

Tips

If you choose to leave a tip, the payment is handled by Google Play or the App Store. We never see your card or payment details. We receive only the store’s confirmation that a tip was made, so Phasor can say thank you. The store’s own privacy policy applies to the payment.

What we collect

Nothing. Phasor does not send us usage data, crash reports or diagnostics. If you contact us, we use what you send only to reply to you.

Children

Phasor is not directed at children under 13, and it does not knowingly collect personal information from anyone, including children.

Your choices and rights

Because your information stays on your phone, you are in control of it: you can change it, export it by any means your phone allows, or delete it by clearing Phasor’s data or uninstalling the app. If you have a question about your privacy, or want to exercise a right you have under the law where you live, contact us and we will help.

Changes to this policy

If Phasor starts doing something new with information, we will update this policy before it does, change the date above, and say so in the app.
