Privacy Policy
Last updated: June 30, 2026
This policy covers the public Matjarina website at matjarina.app. The site is mainly a download page for the Windows installer and a way to contact us for support or setup help.
Short version. We do not sell personal data. The public site does not ask visitors to create an account. Store data entered inside the Matjarina desktop application remains on the customer installation unless the customer intentionally shares it with us for support.
1. Data collected by the website
When you visit the site, our hosting and security providers may process basic technical data such as IP address, browser user-agent, requested URL, response status, and security events. We use this only to operate, protect, and improve the site.
2. Download and support data
The download button may record a lightweight event so we can understand whether the installer is reachable. If you contact us, we process the details you choose to send, such as your name, phone number, email, store name, screenshots, or installation notes.
3. Desktop application data
Matjarina is installed on Windows for store use. Sales, products, customers, stock, receipts, labels, warranties, and similar business records are handled by the installed application. We do not receive that business data through the public website unless you send it to us for support.
4. Cookies
The site uses first-party preferences such as mtj.theme andmtj.locale to remember theme and language. We do not use advertising cookies on the public site.
5. Providers
We use Cloudflare for DNS, hosting, edge delivery, and security. Email or messaging providers may process support conversations when you contact us.
6. Retention
Website security logs are kept only as long as needed for operation and abuse prevention. Support messages are kept while the request is active and for a reasonable period afterwards in case the same issue returns.
7. Your rights
You can ask us to access, correct, or delete personal information you have sent to us. Write to privacy@matjarina.app and we will respond in writing.
8. Security
The public site is served over HTTPS and protected by security headers. See our security page for vulnerability reporting.
