Privacy Policy
Last updated: November 3, 2026
1. Operator
This website is operated by Solid Grid Systems GmbH, Bundesallee 187, 10717 Berlin, Germany.
2. Your Audio Never Leaves Your Device
All audio processing runs locally, in your browser. Your samples are never uploaded to us, and there is no server that could receive them — the decoding, the editing and the encoding all happen on your own machine, and the exported file is written there too. This is the central promise of the Service and everything below is written so as not to weaken it.
3. What We Collect, in Short
What reaches us is anonymous usage measurements (section 4).
4. Usage Measurement
This website uses a privacy-focused, cookieless analytics tool that we self-host. Data never leaves our infrastructure, no cookies are set, and no cross-site tracking takes place.
Besides page views (URL, referrer, browser, OS, country, screen size), we record how the beat maker is used — that a file was loaded, exported or refused. These measurements describe your file, never its contents: the extension, whether the file header matches it, the length and size as coarse ranges rather than exact values, and the reason a file could not be opened. We never record filenames, and nothing you type is recorded.
The measurements exist to find and fix faults and to understand which features are worth building on. The legal basis is our legitimate interest in a working and improving service (Art. 6(1)(f) GDPR).
5. Storage on Your Device
This site sets no cookies, and a page view stores nothing on your device — which is why there is no consent banner. Something is stored only when you use a function that needs it, and only what that function needs (§ 25(2) no. 2 TDDDG):
• Editor settings (in local storage) — when you change them, such as the metronome's volume, so the editor remembers them.
You can remove all of it at any time by clearing this site's data in your browser.
6. Your Rights (GDPR)
If you are located in the EU, you have the right to access, correct, or delete your personal data, to restrict its processing, to data portability, and to object to processing based on our legitimate interest (Art. 21 GDPR). You also have the right to lodge a complaint with a supervisory authority. To exercise your rights, contact us at hi@solidgridsystems.com.
7. Changes
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date.
