What this website does and does not do

This website does not use cookies, analytics, advertising or tracking tools. All fonts and scripts are served from our own domain, so your browser does not contact any third-party servers to display it.

The form at the bottom of the page does not send anything to our servers. When you submit it, your email app opens with a message prepared for you. Nothing is sent until you press Send in your email app.

Data we process and why

Technical request data (IP address, browser type, time and address of the requested page). It is processed by our hosting provider, Cloudflare, to deliver the website and protect it from abuse. Legal basis: legitimate interest (Article 6(1)(f) GDPR).

Emails you send us (name, email address and the content of your message, including the description of your idea). We use them to reply and to prepare an offer. Legal basis: steps taken at your request before entering into a contract (Article 6(1)(b) GDPR) or our legitimate interest in answering enquiries (Article 6(1)(f) GDPR). We keep them for as long as the conversation lasts and, if no cooperation follows, for no longer than three years after the last contact. If we work together, we keep documents for the period required by tax and accounting law.

Who receives the data

Cloudflare, Inc. (hosting, content delivery and forwarding of emails sent to hi@jstechnology.app) and Google LLC (the Gmail mailbox that receives them). These providers may process data outside the European Economic Area, including in the United States, on the basis of the EU–US Data Privacy Framework or standard contractual clauses. We do not sell personal data.

Your rights

You can ask us for access to your data, rectification, erasure, restriction of processing, and data portability where it applies. You can object to processing based on legitimate interest. To use any of these rights, write to us at the address above.

You also have the right to lodge a complaint with a supervisory authority. In Poland this is the President of the Personal Data Protection Office (UODO), uodo.gov.pl.
