Visitor counting without cookies
To know how many people visit the site and where they come from, we count visits on our server. We use no cookies for this, store nothing on your device and load no tracking script.
For each page you open we record the page path, the domain of the site that sent you (if it is an external site), the device type (phone, tablet or computer) and an approximate location (country, region and city) that Vercel estimates from your IP address.
We use your IP address and browser identifier only to calculate a daily anonymous visitor code. We do not store the IP address or the browser identifier. The key for the calculation changes every day and is deleted after 48 hours, so the codes cannot be linked to you or to each other across days.
Individual visit records are deleted after 40 days. We keep only aggregate numbers for longer (for example visitors per day, country and city).
The legal basis is our legitimate interest in measuring visits and improving the site (Art. 6(1)(f) GDPR). Synco (synco.hr) carries out this processing for us as a processor, and the data is kept in the EU (DigitalOcean, Frankfurt).
If you turn on Global Privacy Control or Do Not Track in your browser, we do not count your visits. You can also object to this processing using the contact details in this policy.
Cookie policy
We load Google Tag Manager only after consent. The container runs Google Analytics 4 and Google Ads. Using the site is not consent.
Processors: Vercel (web, US), DigitalOcean Frankfurt (API and database), Amazon Web Services Stockholm (email, EU), Synco (visitor counting, EU). Google (GTM, Analytics, Ads) only after consent. US transfers use standard contractual clauses.
This table is the accurate list. If we add a new tool, we will update it and ask for consent again.
