What data is processed

• What you enter in the tools: not collected. Calculations run entirely in your browser and nothing is sent to a server. Some tools save your inputs in your own browser's local storage so you do not lose them when you reload; that data never leaves your device.
• Email: if you write to me, your address and message are used only to reply. Legal basis: your consent when writing. They are kept for the duration of the conversation and a reasonable time afterwards.
• Technical data: the hosting provider (Cloudflare, Inc.) processes your IP address and technical request data to serve the site and protect it against attacks. Legal basis: legitimate interest in the operation and security of the site.
• Advertising: the site shows Google AdSense ads. Google and its partners may use cookies and identifiers to serve ads and measure their performance. Personalised ads are only shown with your consent, which you can give or withdraw in the cookie banner. More information in the cookie policy and in how Google uses cookies in advertising.

Recipients and transfers

No data is shared with third parties except the providers above (Cloudflare and Google), which may process it outside the European Economic Area under the EU-US Data Privacy Framework or standard contractual clauses.

Your rights

You can exercise your rights of access, rectification, erasure, objection, restriction and portability by writing to [email protected]. If you believe your request has not been handled properly, you can file a complaint with the Spanish Data Protection Agency (aepd.es) or with your local supervisory authority.
