Data you enter into our tools

All tools run in your browser. The data you paste is processed on your device and is never sent to our servers.

Questions you send us

When you use the support form or write to us, we receive your name, email address and question. We use them only to reply and to improve our guides. We do not sell them.

Messages sent through the support form are delivered to us by Formspree, which processes them under its own privacy policy.

Advertising and cookies

We may show ads from Google AdSense. Google and its partners use cookies to serve ads based on your visits to this and other websites. You can opt out of personalised advertising in Google Ads Settings. Learn more at How Google uses information from sites that use its services.

Purchases

We do not process payments. When you buy goodies from our Shop, you are taken to our print-on-demand store partner, which collects your name, address, email and payment details to fulfil your order under its own privacy policy.

Analytics

We may use privacy-friendly analytics to count visits. If we do, we will list the provider here.

Your choices and rights

You can ask us to access, correct or delete the personal information you sent us by writing to support@emvstack.dev. Depending on where you live, including the European Economic Area, the United Kingdom, Canada and some US states, you may have additional rights under local law, and we will respond to requests as that law requires.

Children

This site is intended for professionals and is not directed to children under 13. We do not knowingly collect personal information from them.

Changes

We may update this policy. The date at the top shows the latest version.
