Who operates this website

Visiting the website
This is a static website hosted on GitHub Pages. Loading a page sends ordinary connection information, such as your IP address, browser information and requested address, to the hosting and network providers. They may process request and security logs to deliver and protect the website. See GitHub's Privacy Statement for its processing and retention practices.
Fonts and site assets are served with the website. Except for the limited Google Ads measurement described below, the website's own code does not add behavioral analytics trackers. Links to social networks, stores and other external services are subject to those services' own privacy policies when you visit them.
Google Ads conversion measurement
The byBartonek homepage and JB_Drill campaign landing pages use a Google Ads tag to understand whether an advertising campaign led to a visit to Google Play or Microsoft Store. A conversion event is sent only when a visitor activates one of those two store links on the Download page; merely loading a page is not counted as a store conversion. The event identifies the advertising conversion and its configured value, but byBartonek does not send a name, email address or JB_Drill account identifier.
Advertising storage, analytics storage, ad user data and ad personalization are denied by default. These pages ask whether the visitor allows advertising measurement. If allowed, Google may use cookies or similar storage for attribution. If declined, those storage permissions remain denied; the Google tag may send limited consent-state and cookieless measurement signals. The choice is saved in the browser's local storage, applies across these pages and can be changed using Privacy choices in their footer.
Google processes this information under its own terms and privacy arrangements. See Google's Privacy Policy and Google's information about advertising data.
Contact correspondence
If you email us, we receive your email address, message and any details or attachments you choose to send. We use them to answer your request, provide support and handle related security or legal matters. Do not send passwords, payment-card details or unnecessary personal information.
Correspondence may be processed by email and technical service providers acting for us. Depending on the purpose, processing is necessary to provide a requested service, pursue legitimate interests in responding and operating securely, or comply with a legal obligation. Providers may process data in countries where they operate, under their applicable data-protection arrangements. We do not sell personal data.
Retention and your choices
There is no single automatic deletion period for correspondence: it depends on whether the request is still open and whether specific records are needed for security, a dispute or a legal obligation. You may request deletion at support@bybartonek.com. Identify the correspondence or application concerned without sending sensitive credentials. We may need proportionate verification of your authority before acting. If specific records must be retained, we will explain the reason and applicable period in our response.
Requests concerning an application's data are handled under that application's policy; for JB_Drill use the dedicated instructions. Records held independently by hosting, email or other external providers remain subject to their policies and applicable obligations.
Your rights
Depending on applicable law, you may have rights to access, correct or delete personal data, restrict or object to processing, and obtain data portability. Contact privacy@bybartonek.com. You may also contact the Czech Office for Personal Data Protection or another competent supervisory authority.
We may update this page as the website changes. Application-specific practices are described separately rather than assumed to be the same for every byBartonek product.
