Cookie and similar technologies policy
Last updated: 7 September 2026.
This policy explains the cookies and similar technologies used by ATOMIC X SUPPLY S.L. (Spanish tax ID B56779341) on atomxsupply.com. It should be read with our Privacy Policy.
It is provided under section 22.2 of Spanish Law 34/2002, Regulation (EU) 2016/679 (GDPR), Spanish Organic Law 3/2018 and the current guidance of the Spanish Data Protection Agency.
1. Your choice
Necessary cookies support the session, cart, security and checkout. Analytics and advertising cookies, Meta Pixel and the Conversions API are enabled only with your consent. The first layer offers Reject, Configure and Accept at the same level. You may change or withdraw your choice at any time through Cookie preferences in the footer. The choice is stored for 180 days unless purposes, providers or this policy change.

Names may change after browser or provider updates. Non-essential categories are used only when accepted. Google Consent Mode keeps analytics and advertising storage denied until the corresponding consent exists.
3. Meta Pixel and Conversions API
After advertising consent, browser and server channels share an event identifier to prevent duplication. Meta may receive the event (PageView, ViewContent, AddToCart, InitiateCheckout or Purchase), time, URL, event ID, IP address, user agent, _fbp, _fbc, and catalogue ID, variant, quantity, price, value and currency where relevant.
With advertising consent, the Conversions API may send Meta the email address associated with the account, the telephone number from the delivery address and a pseudonymous external_id. These data are normalised and SHA-256 hashed before transmission; they are not sent without consent or in plain text. We do not use first name, surname or postal address as matching parameters. Pending CAPI events are encrypted locally and expire after 24 hours; content is removed after delivery or discard and terminal operational metadata is pruned within 90 days.
Provider: Meta Platforms Ireland Limited. See Meta's Privacy Policy, Cookie Policy and Business Tools Terms.
4. Google
The site has Google Tag Manager, Google Analytics and Google marketing services. Consent signals are denied by default, and analytics or advertising storage requires the relevant choice. Google may receive limited technical consent-status signals under Consent Mode. See Google's Privacy Policy and cookie information.
5. International processing
Meta, Google, Cloudflare and payment providers may process information outside the EEA. Where required, processing relies on a valid adequacy decision, European Commission Standard Contractual Clauses and supplementary safeguards. We do not rely on the framework invalidated in 2020.
6. Controls and contact
Use Cookie preferences in the footer or your browser settings. Blocking necessary cookies may prevent account, cart or payment features from working. Withdrawal does not affect earlier lawful processing.
