Purchase measurement and cookies (updated 8 September 2026)

This section applies to za5dvanact.cz, o5dvanast.sk and its5to12.com. For Google Merchant Center measurement it supersedes older general statements about anonymity, consent and retention in this document. With consent to the tracking and performance category we measure visits and completed purchases. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. The purpose is to evaluate our product listings on Google; the legal basis is your consent (Article 6(1)(a) GDPR). Without consent we do not load the new Google tag or send this purchase event.

We send an order identifier without a name, product identifiers, prices and quantities, discounted merchandise value including VAT, shipping and currency. During the connection Google also receives technical data such as your IP address, browser information and cookie or click identifiers. The event does not contain your name, email, phone, address or order note. This integration does not use enhanced conversions or personalised advertising. Data are pseudonymous, not guaranteed to be anonymous.

After consent we store za5_mc_source for 30 days to select the CZ/SK source, and za5_mc_purchases in localStorage to limit repeated purchase submissions; entries older than 30 days are pruned on subsequent use. Google may use measurement cookies such as _gcl_*. We limit configurable cookie lifetimes to 30 days; specific Google cookie lifetimes also depend on its settings and policies. The Merchant Center attribution window is 30 days, not automatically the retention period for all data held by Google.

When switching between these domains after consent, links may contain za5_mc and the _gl measurement parameter to preserve the original source. Measurement on the destination domain still requires local consent. Direct English-domain purchases without an earlier CZ/SK source are sent to the Czech source. We do not send the same event to both accounts.

You can reject or withdraw consent using Cookie settings in the footer. After withdrawal we stop sending further purchase events, notify Google of the denied consent and remove accessible local measurement cookies and records for this integration. Choices on other domains can be changed separately. Withdrawal does not affect the lawfulness of earlier processing. You can request access or erasure using the contact details in this policy. Google may process data outside the EEA; its policies linked below describe applicable transfer mechanisms and retention. Essential cookies for the cart, security and storing your consent choice are separate from this optional measurement.

Placing an order or accepting the terms and conditions does not give consent to optional cookies or purchase measurement. You choose this separately in Cookie settings and may withdraw it at any time without affecting your order.
