Privacy policy

Last updated: 31 August 2026.

This policy explains how the ZnTECH QR Code generator handles information, including under Brazil’s LGPD.

We do not collect personal data

We do not ask for your name, email, phone or an account. We do not use advertising or tracking cookies. QR Code content (URL, phone, Wi-Fi, vCard, etc.) is processed only on your device and is not sent to our servers.

Local storage

If you install the app (PWA), the browser may cache static files for offline use. That data stays on your device.

Infrastructure

The site is hosted on Cloudflare. Like any website, the provider may process technical connection data (such as IP address) to deliver the page, provide security and operate the network. We do not use that data to identify you.

Donations

If you send a crypto coffee, the amount and payment details are sent to Plisio to process the transaction. If you donate via PIX, the amount is sent to Mercado Pago to generate the QR Code. We do not ask for a name or an account to donate.

Your rights

Because we do not store accounts or QR Code content, we have no personal database to access, correct or delete. Questions: zntech.com.br.

Changes

We may update this policy. The current version is the one published on this page.
