What We Do
On your first visit, you choose how you see ads. That's it.
Your Cookie Choices
Language cookie (required): We store your language preference so the site stays in your chosen language.
Generic ads: Context-based ads only, no user tracking. Ads are shown based on page content, not your browsing history.
Personalized ads: Ads tailored to your interests and browsing history, requiring tracking cookies from Google AdSense.
Google AdSense — Personalized Ads Mode
If you choose "I Accept Cookies", we enable Google AdSense with personalized ad targeting.
Google AdSense will set cookies on your device to track your browsing behavior across partner sites, build advertising profiles based on your interests, show you advertisements tailored to those interests, and measure ad performance and conversion.
Legal basis: Explicit consent (Article 6(1)(a) GDPR).
Google's Privacy Policy: https://policies.google.com/privacy
Opt out of personalized ads: https://adssettings.google.com/
Generic Ads — Ezoic Non-Personalized Mode
If you choose "Generic Ads", we serve ads via Ezoic with no user tracking or profiling.
Ezoic shows ads based on the page topic and content you are viewing, your general location (country/region only), and time of day.
No cookies are set for ad targeting. Ezoic may set technical cookies for ad serving and fraud prevention, but these do not enable behavioral profiling. This is fully GDPR compliant (Article 6(1)(f) — legitimate interest in fraud prevention).

We do not collect any of the contents of the PDFs, images, documents or files that you process. We do not store any calculator inputs, unit conversion values, personal identifiers or other data that could be used to identify which files you have used. The only data that may be cached is your language preference and ad choice preference.

Like every web server, our host records standard access logs (IP address, user agent, timestamp) for security. These logs are retained and rotated regularly.

Your rights:
Change your ad preference: Clear your cookies or return to the banner to choose again.
