Privacy Policy

Last updated: 2026-07-31

1. Data we process

• data entered in forms (for example birth date and location),
• technical data about browser and device,
• traffic, product usage, and page performance statistics.

2. Processing purposes

• running the calculator and presenting results,
• maintaining service stability and security,
• measuring traffic and improving the product.

3. Legal basis

Essential data is processed to provide the service. Google Analytics storage is processed based on user consent. Cloudflare Web Analytics provides cookieless, aggregated traffic and performance measurement.

4. Retention period

Data is retained for as long as needed for the purposes above, or until consent is withdrawn (for optional analytics cookies).

• The current analysis request, result, and filters are stored in sessionStorage for up to two hours so the result can be restored after visiting a guide. "Reset analysis" removes this session. A short language preference may also be stored in sessionStorage when you open the calculator from a guide.
• Birth date and location are stored in localStorage for up to one year only when "Remember my data" is enabled. "Clear saved data" removes both the short analysis session and this optional form record.
• No cookie is used to store an analysis or birth data.

5. Data recipients

Data may be processed by infrastructure and analytics providers including Netlify, Google Analytics, and Cloudflare, only as needed for the purposes described above.

6. Your rights

You may request access, correction, deletion, restriction, portability, and you may lodge a complaint with your local supervisory authority.
