Privacy Policy

Last updated: October 2026

Who we are

Pulse HD Audio Player is developed and published by StumpCo Labs. If you have any questions about this policy, you can reach us at support@stumpcolabs.com.

What data we collect

Pulse HD does not collect any personal data. Specifically:

• We do not collect your name, email address, or any identifying information
• We do not collect your location
• We do not collect information about the music files on your device
• We do not use analytics or tracking tools
• We do not use advertising networks
• We do not create user accounts or profiles

How the app uses your device

Pulse HD requests the following permissions to function:

• Read Media Audio: to access and play the music files stored on your device. These files never leave your device.
• Foreground Service / Media Playback: to keep music playing while the app is in the background and to show playback controls on your lock screen and notification bar.
• Record Audio / Microphone (optional): used by the visualizer to react to music. When you turn on microphone mode, sound is analyzed in real time on your device to animate the visuals. Audio is never recorded, saved, or sent anywhere. You can use the app without granting this permission.
• Bluetooth (optional): used to recognize when your car or headphones connect, so Pulse HD can turn on Car mode or apply the equalizer settings you saved for that device. Device information stays on your device.
• Internet: used only for the optional online features described below (lyrics, Last.fm, your music server) and for Google Play purchases.
• Notifications: used to show playback controls in your notification bar and on your lock screen.
• Write Media (optional): used only if you choose to edit song tags (title, artist, album) through the tag editor. Only files you explicitly choose to edit are affected.

Your music files and the data accessed through these permissions are not transmitted off your device, except as described under Third party services.

Data storage

All app settings, including your equalizer profiles, visualizer configurations, playlists, favorites, listening statistics, and skin preferences, are stored locally on your device using Android's standard storage. This data is not sent to StumpCo Labs and is removed when you uninstall the app.

If you sign in to Last.fm, Pulse HD stores a Last.fm session key on your device so you stay signed in. Your Last.fm password is never stored. If you connect a music server, its address and your sign-in details are stored on your device so the app can connect to it.

Third party services

Pulse HD contains no advertising, analytics, or tracking tools, and StumpCo Labs does not receive your data. Some optional features connect to outside services, and only when you use them:

• Synced lyrics (LRCLib): when you open lyrics, the song's title, artist, album, and length are sent to LRCLib to find matching lyrics. No personal information is sent.
• Last.fm (optional): if you choose to sign in, your Last.fm username and password are sent to Last.fm once to sign you in, and the songs you play are sent to your Last.fm profile ("scrobbling"). This data is handled under Last.fm's privacy policy. You can sign out at any time in Settings.
• Your music server (optional): if you connect a Subsonic-compatible server such as Navidrome, Pulse HD communicates only with the server address you enter.
• Google Play: purchases of Pulse HD Pro are processed by Google Play. StumpCo Labs does not receive your payment details. Google's handling of this data is covered by Google's privacy policy.

Children's privacy

Pulse HD is not directed at children under 13, and StumpCo Labs does not knowingly collect information from anyone, including children.

How to delete your data

StumpCo Labs does not store your data on our servers, so everything can be removed by you directly:

• Data stored in the app (playlists, favorites, settings, equalizer profiles, listening statistics, Last.fm session, music server details): open your phone's Settings → Apps → Pulse HD → Storage → Clear storage, or uninstall the app.
• Last.fm sign-in: in Pulse HD, go to Settings → Last.fm → Sign out.
• Songs already sent to Last.fm: delete them in your Last.fm account settings. This data is held by Last.fm, not StumpCo Labs.
• Need help? Email support@stumpcolabs.com with the subject "Data deletion request" and we'll respond within 30 days.

Changes to this policy

If we ever change this privacy policy (for example, if we add new features that require new permissions), we will update this page and change the date at the top. We will never introduce data collection without clearly communicating it and updating this policy first.

Your rights

Because StumpCo Labs does not collect personal data, we hold nothing to access, correct, or delete. Data stored in the app can be removed at any time by clearing the app's storage or uninstalling it. To remove data shared with Last.fm, use your Last.fm account settings. If you have questions or concerns, please contact us and we will respond promptly.
