Privacy Policy

PixelFlow · Last updated: June 13, 2026

PixelFlow does not collect, store, sell, or share any of your personal data, and it never sends anything to us. There are no accounts, no sign-in, no analytics, no advertising, no tracking, and no third-party analytics SDKs. We run no servers of our own. PixelFlow has one job, driving a Divoom Pixoo 64 LED panel, so it talks directly to your panel on your Wi-Fi and to a few Apple services plus Divoom’s device-discovery service. Everything that leaves your phone, and where it goes, is listed below.

Permissions the app requests, and why

Apple Music and media library: reads the title, artist, and cover art of whatever is playing in your Music app so it can show the artwork on your display. This is read on your device. Nothing about your library is sent to us.
Microphone (Shazam): in the Shazam-based now-playing mode, the app listens through the microphone and sends an audio fingerprint to Apple’s Shazam service to identify the song. The audio is used only to recognize the track. It is never recorded, saved, or sent to us.
Location (Weather): when you open the Weather module, the app uses your approximate location, accurate to about a kilometer and only while the app is open, to fetch current conditions from Apple WeatherKit. Your location goes to Apple to return the weather. It is not stored and never reaches us.
Local network (Pixoo): the app sends image frames, brightness, and text to your Pixoo 64 directly over your Wi-Fi using the panel’s local IP address. This traffic stays on your own network.

You can grant or revoke any of these at any time in the iOS Settings app. Each feature only runs when you choose to use it.

Services the app connects to

When you use a feature, the data it needs goes straight to the service that provides it, never through us. Each is governed by that provider’s own privacy policy.

Apple Shazam (ShazamKit): receives an audio fingerprint of nearby sound in order to name the song that is playing.
Apple WeatherKit: receives your approximate location in order to return local weather conditions. Weather data is provided by Apple Weather.
Apple iTunes Search: when a playing track has no embedded cover, the app sends the song title and artist to Apple’s public iTunes Search API to look up the artwork.
Divoom device discovery: to find your Pixoo automatically, the app asks Divoom’s cloud which Divoom devices share your network’s public IP address, then connects to the one it returns. That request makes your network’s public IP visible to Divoom. No account or personal data is sent. You can skip it entirely by tapping “Enter Pixoo 64 IP…” and typing the address yourself. PixelFlow is an unofficial app and is not affiliated with, authorized, or endorsed by Divoom.
Your Pixoo 64: receives the frames the app draws, over your local Wi-Fi. Nothing leaves your local network.

What we receive

Nothing. PixelFlow has no backend, no analytics, no advertising, no third-party tracking SDKs, and no user accounts. We, the developer, never receive any data from the app. The microphone audio, your location, and your now-playing details are used only on your device or sent only to the Apple or Divoom service that powers the feature you opened.

Children’s privacy

The app does not collect any data from anyone, including children, and contains no ads, in-app purchases, or social features.
