What we collect (almost nothing) and why.
Last updated: September 26, 2026
Smrt Stem is an offline audio tool. Your audio files never leave your computer, and the app collects only what's needed to manage software licenses. This website is a little different: with your permission, it uses Google Analytics and the Meta Pixel. If you say no, neither one loads.
Smrt Stem analyzes audio stem files for quality control purposes. All audio analysis happens locally on your machine. No audio data is uploaded, transmitted, or stored on any server.
License Activation
When you activate a license key, the following information is sent to LemonSqueezy, our merchant of record and licensing provider, to verify your purchase:

The Smrt Stem app does not use any analytics services, advertising networks, or tracking tools.

We don't run our own servers. Your license and purchase information is kept by LemonSqueezy as part of your purchase record. Email list subscriptions are kept until you unsubscribe.

If you consent to analytics or advertising, Google and Meta retain that data according to their own policies and the settings available in our accounts with them. We don't control every retention period on their side. Local Smrt Stem data can be removed at any time by deleting the application and its support files.

Depending on where you live, you may also have rights to access, correct, delete, restrict or object to certain processing of your personal information, or request a portable copy. You may also have the right to make a complaint to your local data-protection authority.
