The operator named in the Impressum is responsible (controller) for processing personal data in connection with this website.
For privacy questions or requests, you can contact us via the contact page.
If you choose to save your plan, the calculator stores it locally in your browser so you can return later. We also store a small amount of site preference data locally, such as your selected currency and whether you have already dismissed certain prompts.
This locally stored data stays on your device unless you choose to share it. At this time, we do not use first-party cookies for calculator accounts or logins.
Google Ads are currently disabled on this site, so no Google AdSense ad requests are made.
We currently use Cloudflare Web Analytics to understand overall traffic and improve the site. According to Cloudflare, this service is designed to provide aggregated usage information without using client-side cookies or local storage for analytics purposes.
Where applicable under privacy law (for example under the GDPR), we may process personal data as necessary to provide and secure the site, to respond to messages you send us, and to operate advertising and analytics features. Depending on the situation, this may be based on our legitimate interests (such as operating and improving the site), your consent, or the need to respond to your request.
Recipients may include hosting and infrastructure providers, analytics providers, and advertising providers involved in operating the site. These providers may act as independent controllers or as processors, depending on the service and contract.
Calculator plans and preferences stored in your browser remain there until you clear them or your browser removes them. If you contact us by email or through the contact page, we keep your message and related data for as long as needed to handle your request and any follow-up, and as required by applicable retention obligations.
If you are in the EU, EEA, or UK, you may have the right to request access to your personal data, correction, deletion, restriction of processing, data portability, and to object to certain processing, where the legal requirements are met.
You may also have the right to withdraw consent at any time where consent is the legal basis for processing, without affecting the lawfulness of processing based on consent before its withdrawal.
To exercise these rights, please contact us using the details in the Impressum or via the contact page. You also have the right to lodge a complaint with your local data protection authority.
We may update this Privacy Policy from time to time, for example when we add new features or when laws or guidance change. The date at the top of this page shows the latest update. Please check this page regularly for updates.
Additional legal information, including our contact details and mandatory disclosures, can be found in the Impressum.
