SoundCloud Enhanced Pro is a browser extension built and maintained by UnifyBrowse, an independent studio. This page explains what data the extension collects, why, and how it's handled. It supplements UnifyBrowse's general Privacy Policy, which governs the website, accounts, and billing.
What the extension does
SoundCloud Enhanced Pro runs on soundcloud.com to resolve track/playlist streams and convert them (M4A → MP3) for download, with optional Pro features gated by a license key.
Information collected
| Category | What's collected | Why |
|---|---|---|
| SoundCloud URLs / track IDs | The URL or ID of the track/playlist you act on | Sent to our backend to resolve metadata and a direct streaming URL |
| License credentials | License key and a device-bound instance ID | Sent to our backend, which validates against Lemon Squeezy, to unlock Pro features |
| Support / feedback messages | The message you write, and your email only if you choose to provide it | Used solely to respond to you |
| Anonymous usage events | Feature usage, browser/OS context, coarse IP-derived location | Forwarded to our self-hosted OpenPanel analytics through our backend proxy |
| Error diagnostics | Stack traces, extension version, browser context | Sent to Sentry if the extension crashes. PII reporting is disabled |
| Local settings & cache | Preferences, download/listening history, cached track metadata | Stored only in your browser's local storage; never transmitted unless the feature explicitly says so |
We do not collect your SoundCloud account credentials — the extension never asks for or sees your SoundCloud login.
What we don't collect
- SoundCloud passwords or session cookies.
- Browsing activity outside soundcloud.com, sndcdn.com, soundcloud.cloud, and the extension's own pages.
- The contents of files you download beyond what's needed to resolve and stream them.
- Advertising identifiers. There are no ads and no ad trackers in this extension.

Data retention
- License/device-activation records persist while your license is active, plus a reasonable window for support and fraud prevention.
- Support messages are retained only as long as needed to resolve your request.
- Anonymous analytics events are retained in aggregate and aren't tied to an account.
- Local extension data lives on your device until you clear it or uninstall.
Your rights
Request access, correction, or deletion of any personal data we hold by contacting us below. Local data can be cleared via your browser's extension settings or by uninstalling.
