2. Provision of this website

When you access this website, the web server providing it processes technically necessary connection data, in particular IP address, time, address accessed, browser information and response status. This serves to deliver and secure the website. The legal basis is Article 6 Paragraph 1 Letter f GDPR. Recipients can be the service providers responsible for hosting and technical operation. Technical protocols must be limited to the period necessary for operation and security.

3. No analytics or marketing services

The selected display (light or dark) is only saved locally in the browser. This website loads its fonts, images and scripts from its own web server. It does not use any embedded analytics, advertising or social media services and does not set any cookies itself. The example calculator works exclusively in your browser. Your entries will not be transmitted to us or stored permanently.

4. Contact via email

If you write to us, we will process your email address, the message content and, if necessary, other data provided to process your request. The legal basis is Article 6 Paragraph 1 Letter b GDPR for contract-related inquiries, otherwise Article 6 Paragraph 1 Letter f GDPR. Messages will be deleted as soon as they have been processed and there are no legal retention requirements or legitimate reasons for further storage.

5. Purchase via Stripe

If you use desktop purchasing, you will be redirected to Stripe's payment page. Stripe processes the information required for payment and billing, such as name, email address, billing address and payment details. For customers in the European Economic Area, Stripe Payments Europe, Ltd., 1 Grand Canal Street Lower, Grand Canal Dock, Dublin, Ireland is particularly involved. Other Stripe companies and payment service providers may be involved. Information on data processing and international transfers can be found in the Stripe privacy policy.

We receive payment status, transaction identifier and the customer details required for the order, but not full card details. The legal basis is Article 6 Paragraph 1 Letter b GDPR for contract processing and Article 6 Paragraph 1 Letter c GDPR for legal documentation obligations. Billing data is stored in accordance with legal retention requirements.

6. Download and license activation

To release the download, we check the payment status. For the Windows license, an order mapping, a license key and, upon activation, an installation identifier randomly generated on the device are processed. The identifier is used to assign the activated workstation; Project and customer data from the app are not transferred. The legal basis is Article 6 Paragraph 1 Letter b GDPR. License data remains stored for the provision and management of the purchased license.

7. External store links

Google Play and, if applicable, the Apple App Store are only opened when a link is clicked. The data protection information of the respective operators applies to processing on these platforms. Information about the app itself is available in the App privacy policy.

8. Your Rights

In accordance with the GDPR, you have rights to information, correction, deletion, restriction of processing and data portability. If processing is based on Article 6 Paragraph 1 Letter f of the GDPR, you can object based on your particular situation. You can revoke your consent at any time with future effect. You can complain to a data protection supervisory authority, in particular the State Commissioner for Data Protection and Freedom of Information for North Rhine-Westphalia.
