ProductGuru is operated by Czech Export Advisory s.r.o. ("we", "us", "our"), the data controller under the EU General Data Protection Regulation (Regulation (EU) 2016/679):
Our advertising is served by Adsterra (Adsterra Group Ltd). Advertising partners may process data outside the European Economic Area, including in the United States; such transfers rely on the Standard Contractual Clauses approved under GDPR Art. 46(2)(c). Where you decline advertising consent, ad requests are made in non-personalised mode. We also use affiliate links to eBay Partner Network and Amazon Associates: following one of those links takes you to the merchant, who then processes your data under their own privacy policy. We do not use Google AdSense.
We use Adsterra (Adsterra Group Ltd) to display advertisements on this site. Adsterra is a third-party advertising network; it and its demand partners may use cookies and similar technologies to serve ads based on your prior visits to this website and other websites. We do not use Google AdSense.
We do not control which ads our advertising partner displays, nor do we have access to any personal data it collects.
We use the following types of cookies:
Anonymous page-view count: each page sends one cookieless signal to our own server with the type of page, the name of the referring website, whether you use a phone or a desktop, and whether the page stayed open for 10 seconds. We keep only daily totals — no cookies, no identifiers, no IP address and no personal data are stored. Browsers with Do Not Track or Global Privacy Control enabled send nothing.
On your first visit we ask for your consent via a cookie banner. You may change your choice at any time via our Cookie Policy page. Legal basis: consent (Art. 6(1)(a) GDPR) for advertising cookies; legitimate interest (Art. 6(1)(f) GDPR) for strictly necessary functions.
Beyond Google (above), the following named recipients may receive limited data when you interact with specific pages on this site. We do not pay them for data, and they do not pay us for data — these are technical or affiliate relationships.
5339154706. When you click an affiliate link on a category, brand,
or blog page that points to eBay, your browser is redirected through eBay's
click-tracking endpoint. eBay receives your IP address, User-Agent, the
campaign ID, and the destination listing. We receive a commission on qualifying
purchases; we do not receive your personal data. See
eBay User Privacy Notice.__cf_bm bot-management cookie. Legal basis: legitimate interest
in service availability and security (GDPR Art. 6(1)(f)). Data transfers
to the US are covered by Cloudflare's published Standard Contractual Clauses
(GDPR Art. 46(2)(c)). See

Consent Management Platform, which presents the consent dialog to EEA/UK
visitors and stores your TC string in the euconsent-v2 and
FCNEC cookies (13 months). Google receives your IP address,
User-Agent, the publisher ID (ca-pub-4123820645518057), the
Funding Choices message ID, and your consent decisions. Your AdSense and
GA4 consent state is bridged from Funding Choices into our local
pg_consent store via the IAB __tcfapi bridge so the
rest of the site honours your choice. Legal
basis: consent (Art. 6(1)(a) GDPR). EU→US transfers are covered by
Google's published Standard Contractual Clauses (GDPR Art. 46(2)(c)).

jointly with Google LLC (USA). Aggregate site analytics
loaded on every HTML page. We run under Consent Mode v2 with all
storage parameters defaulted to "denied";
before you accept consent, GA4 sends cookieless pings only (no _ga,
_gid, or _ga_<ID> cookie is set). When you grant
analytics consent via Funding Choices, the cookies above are set and Google
receives your IP address (subject to its in-region IP masking under GDPR),
User-Agent, page URL, referrer, event metadata, and consent state. We have
enabled url_passthrough and ads_data_redaction for
the cookieless-pings path. Legal basis: consent for the cookie-set path
(Art. 6(1)(a) GDPR); legitimate interest in aggregate measurement for the
cookieless-pings path (Art. 6(1)(f) GDPR). EU→US transfers are covered
by Google's published Standard Contractual Clauses (GDPR Art. 46(2)(c)).

Web server logs are retained for up to 90 days. Contact form data is retained until your enquiry is resolved, or for a maximum of 2 years. You may request deletion of your contact record at any time by emailing us.
Depending on your jurisdiction, you may have the right to access, correct, or delete personal data we hold about you, and to object to or restrict processing. To exercise these rights, contact us at [email protected].
ProductGuru is not directed to children under the age of 13. We do not knowingly collect personal information from children.
We may update this Privacy Policy from time to time. Material changes will be indicated by an updated "Last updated" date at the top of this page. Continued use of the site after such changes constitutes acceptance of the new policy.
As required under GDPR Art. 35, we have assessed the privacy risks of third-party advertising. A DPIA has been conducted and is available on written request. Key mitigation: personalised ads require explicit consent; non-personalised mode is the default until consent is given, and in that mode no user-profiling cookies are set by us.
