Privacy policy
Last updated: 29 September 2026
This policy explains what data the "ESP32 Projects" website processes, why, and how you can control it. Send any data-related questions to [CONTACT_EMAIL].
What we process
- No sign-up. There are no visitor forms; we don't collect names, phone numbers or email addresses.
- Technical data. The server and hosting provider may briefly process your IP address, browser type and request time to operate and protect the site.
- Anonymous visit statistics. We count page views on our own server, without cookies or third-party services. Only daily totals are stored: how often a page was opened, its language, the device type (desktop / phone / tablet), the website you came from and searches made on this site. To count unique visitors, a hash of the IP address and browser type is computed with a salt that changes every day; these hashes are deleted the next day and the IP address itself is never stored.
- Strictly necessary cookies.
connect.sidis used only for administrator sign-in and is never set for regular visitors. - Your cookie choice is stored in your browser's
localStorage(cookie_consent) and never sent anywhere.
Advertising
This site shows ads via Google AdSense to all visitors — this is how the site is funded. Your choice in the cookie banner decides what kind of ads you see:
- "Accept" — personalised ads: Google and its partners may use cookies and similar technologies to serve ads based on your visits to this and other websites.
- "Necessary only" (and until you make a choice) — non-personalised ads: they are not based on your interests or browsing history, but Google may still use cookies for frequency capping, fraud prevention and ad measurement.
- How Google uses information from partner sites
- Google ad settings — you can turn off personalised ads there.
Legal basis
Personalised ads — your consent (Art. 6(1)(a) GDPR). Non-personalised ads — our legitimate interest in funding a free website. Technical data and anonymous statistics — our legitimate interest in keeping the site secure, running and improving it (Art. 6(1)(f) GDPR).
Your rights
You can change your choice or withdraw consent at any time via , and request access to, correction or deletion of your data by writing to [CONTACT_EMAIL]. You also have the right to lodge a complaint with your data protection authority.
