2. What we collect

When you browse this site we may process:

  • Server and access logs — IP address, browser type, requested URL, timestamp. Generated by our host (Vercel) for security and operations.
  • Analytics data — Google Analytics 4 may collect usage statistics (pages viewed, device type, approximate location). IP addresses are anonymised where supported. You can block analytics cookies in your browser; see our Cookie Policy.
  • Contact by email — if you write to us, we process the information you send (name, email, message content).

We do not run comment forms, newsletters, or e-commerce on this site. We do not knowingly collect data from children.

  • Legitimate interest — operating and securing the website, understanding aggregate traffic via analytics.
  • Consent / opt-out — analytics cookies. You can refuse them via browser settings or Google's opt-out add-on (see Cookie Policy).
  • Contract / pre-contractual steps — responding to business enquiries by email.

4. Processors and hosting

The site is hosted on Vercel, Inc. (USA/EU regions). Vercel processes access logs and delivers static files. Google LLC processes analytics data for analytics. Both providers may transfer data outside the EEA under appropriate safeguards (e.g. Standard Contractual Clauses).

See also our Cookie Policy for cookie details.

5. Retention

  • Server logs — typically retained by Vercel for a limited period per their policy.
  • Analytics — per Google Analytics retention settings (default 14 months unless changed).
  • Email correspondence — as long as needed for the enquiry and legal obligations (usually up to 4 years for business records).

6. Your rights

Under the GDPR you may request:

  • access to your personal data;
  • rectification or erasure;
  • restriction of processing;
  • data portability (where applicable);
  • objection to processing based on legitimate interest;
  • objection to analytics processing (block cookies in browser or use Google's opt-out add-on).

Contact martin@pagespeed.cz. You may also lodge a complaint with the Czech Data Protection Authority (uoou.cz).

7. Changes

We may update this policy. Material changes will be reflected on this page with a new “Last updated” date.
