Privacy
What we store, and why.
Controller
Christian Kaubisch, Matter Synth, Im Eschfeld 3, 52351 Düren, Germany. Contact: email.
Website hosting and analytics
The website is hosted on Vercel. Server logs (including IP address) are kept for a short time. We use Vercel Analytics and Speed Insights: cookieless, aggregated, without cross-site tracking.
Cookies and local storage
We set no cookies. One localStorage key, matter-theme, stores your theme choice on your device.
Checkout
Payment is handled by Paddle as Merchant of Record. Paddle is an independent controller for payment data; see the Paddle privacy policy.
License issuance
We store your name, email address, Paddle transaction id, license id and revocation status in a Neon Postgres database (processor, hosted in the EU or US). Legal basis: Art. 6(1)(b) GDPR. Retention: as long as the license exists, plus statutory commercial and tax retention of 10 years (§ 147 AO).
License email
The license email is sent through Resend (processor).
Installer download
Installers are delivered through signed Cloudflare R2 links. Download events store IP address, platform and license id for 90 days to detect license sharing. Legal basis: Art. 6(1)(f) GDPR.
License recovery form
The form stores your email address and hashed IP data for a short time for rate limiting.
Support email
If you write to email, we process your message and address to answer it.
The plugin
The plugin works offline and does not contact any server; see the License Policy.

The competent authority for North Rhine-Westphalia is the Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen. There is no automated decision making.
