Cookie Policy
1. Essential / necessary
- SELSESSID — PHP session cookie used for CSRF protection of the contact form on builds where the form is active. HttpOnly; SameSite=Lax; Secure on HTTPS. Lifetime: session.
- SELADMIN — session cookie for the protected lead administration area only (path
/admin/). HttpOnly; SameSite=Strict; Secure on HTTPS. Lifetime: session / idle timeout.
2. Preference storage
Cookie preference choices may be stored in browser localStorage under key sel_consent_v1. Short-lived attribution parameters for completing an enquiry may be stored in sessionStorage under key sel_attr. These are not third-party advertising cookies.
3. Analytics (optional — Matomo)
Optional analytics uses Matomo, a self-hosted analytics platform available at https://analytics.4app.cz/ (Site ID 47). Matomo scripts and measurement requests are loaded only when (1) the operator has enabled Matomo collection in the production website configuration, and (2) you grant analytics consent via the cookie banner (Accept optional, or enable Analytics under Customize and save).
When those conditions are met, the site may load https://analytics.4app.cz/matomo.js and send measurement requests to https://analytics.4app.cz/matomo.php. Matomo is initialised with a consent requirement on this website. Global “cookie-free tracking” enforcement in Matomo is not relied upon; this website uses its own consent banner and preference store (sel_consent_v1).
After analytics consent, Matomo may set cookies such as:
- _pk_id.* — visitor identifier
- _pk_ses.* — session
- _pk_ref.* — referrer / campaign attribution
Cookie names may vary slightly by Matomo version. These analytics cookies are not set before analytics consent. If you reject analytics or later withdraw consent via Cookie settings, further Matomo tracking stops and the site attempts to remove applicable Matomo cookies. Necessary cookies (SELSESSID, SELADMIN) are unaffected.
Analytics may include page views, technical device/browser information, referrer and campaign parameters, and interaction events (for example CTA clicks or form-related signals). Submitted contact-form values (name, email, phone, company, free-text message) are not sent to Matomo. Google Analytics 4 and Google Tag Manager are not used on this website.
Related IP processing (including two-byte IP masking for stored tracking data, and use of the original IP for geolocation enrichment) is described in the Privacy Policy.
4. How to change your choice
Use Reject optional, Accept optional, or Customize in the cookie banner. You can reopen settings anytime via Cookie settings in the footer.
5. Production activation
Until the operator enables Matomo collection in production configuration and the published Privacy and Cookie Policies disclose Matomo as approved, Matomo scripts are not loaded — even if a visitor accepts analytics in the banner. Activation does not by itself enable search-engine indexing of the website.
