This policy explains what personal data this website and our software licensing collect, why, and for how long. We do not sell personal data and we do not use it for advertising.

When you open a page, our hosting provider's web server records technical data such as your IP address, the date and time, the page requested and your browser type. This is needed to deliver the website and keep it secure (legitimate interest, Art. 6(1)(f) GDPR). These logs are kept for a limited period and then deleted.

With your consent, we use Google Analytics, loaded through Google Tag Manager, to count visits and see which pages are read (Art. 6(1)(a) GDPR). Nothing is loaded from Google before you accept analytics cookies in the cookie banner. If you accept, Google sets cookies in your browser and receives your IP address and details of your visit; Google may process this data outside the EU. If you reject, none of this happens. We use no advertising cookies. Fonts are loaded from our own server, not from third parties. If you switch between light and dark mode, that choice is stored in your own browser only and is never sent to us.

If you write to us through the contact form or by email, we receive the details you give us (usually your name, email address and message) by email. We use them only to answer you and, if it comes to that, to prepare an offer (Art. 6(1)(b) GDPR). We keep the correspondence as long as needed for that, and longer only where tax or commercial law requires it.

If you book a call at /book, our booking system on this website's server stores your name, email address, phone number (if given), any note you add and the appointment time, and sends you a confirmation email. We use this to hold the call (Art. 6(1)(b) GDPR) and delete it when it is no longer needed for the appointment and its follow-up.

If you use the quiz at /quiz and ask to see your full result, we store your name, email address, company and phone number (if given), your answers, the calculated result and the time you gave your consent. If you describe your task in the optional text field, we also store that description and use it only to prepare our reply; please don't include other people's personal data in it. We use this only to follow up on your request. The legal basis is your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time by writing to hello@swift4data.com.

Your answers are scored in your browser: nothing is stored unless you submit the form. When you submit it, your details stay on this website's server only until we transfer them into our own customer records, and never longer than 30 days; they are then deleted from the server. Our customer records are kept locally on our own computer, not in a cloud service. To protect the form from abuse we also keep a one-way hash of your IP address for the same 30 days, never the address itself.

We receive a short email telling us that a new submission is waiting. It contains none of your details.

Our desktop software checks its licence with our licence server on this website. Each check sends the licence key, the product, an identifier generated for the computer, the operating system and the app version; the server also records the IP address and the time of the check. The licence itself holds the name and email address of the licence holder. We use this to activate licences, to limit a licence to the computers it covers and to prevent misuse (Art. 6(1)(b) and (f) GDPR). The licence record is kept as long as the licence exists and deleted with it, while the log entries of the individual checks, including the IP address, are deleted automatically after 12 months.

This website, its booking system and its databases are hosted by STRATO GmbH in Germany, which processes the data only on our behalf under a data processing agreement. Emails are handled by our email provider on our behalf. We do not transfer personal data to countries outside the EU/EEA.

You can ask us at any time for access to your data, to correct or delete it, to restrict its processing, or to receive it in a portable format, and you can object to processing based on legitimate interest. Where we rely on your consent, you can withdraw it at any time; this does not affect processing that happened before. Just write to hello@swift4data.com.

You also have the right to lodge a complaint with a data protection authority. In Spain this is the Agencia Española de Protección de Datos (www.aepd.es).

We update this policy when what we do changes. The date at the top shows when it was last updated.
