The platform integrates with major DSPs and ad exchanges via the OpenRTB protocol. ## **Cookies and data collected** Mile.tech sets advertising cookies (mt\_uid, mt\_session, mt\_consent) and reads partner advertising identifiers. It transmits IP, User-Agent, page URL, ad event details and audience segment information to Mile.tech and via the bid stream to partner DSPs. ## **GDPR and ePrivacy** Advertising cookies and the RTB bid stream require prior consent under Art. 5(3) ePrivacy. Use a TCF v2.2 certified CMP. The publisher and Mile.tech may be joint controllers for the bid stream emission, following the Fashion ID CJEU ruling. ## **Data transfers** Mile.tech processes data in the US. Transfers covered by 2021 SCCs and (where applicable) EU-US DPF. Partner DSPs each have their own transfer chain. Maintain a vendor list. ## **Consent management** Block all Mile.tech tags behind a TCF v2.2 CMP. Restrict the partner list to those you can document. Archive TCF strings for at least 6 months. Consider consent or pay alternatives. ## **Compliance checklist** 1\. Sign Mile.tech DPA. 2. Use TCF v2.2 CMP. 3. Run DPIA. 4. Document joint controllership. 5. Restrict partner list. 6. Archive consent strings. 7. Disclose in privacy notice and cookie policy. Compliance ## Mile.tech and the GDPR Mile.tech is classified as “Marketing”. On a site that targets European visitors, it must only load after the visitor consents, and it must be listed in your cookie policy. - Legal basis Consent (Art. 6(1)(a) GDPR and Art. 5(3) ePrivacy) for advertising cookies and downstream RTB - Risk level high - Applicable regulations GDPR, ePrivacy Directive, IAB TCF v2.2 ### Impact assessment (DPIA) Mile.tech processes IP, User-Agent, ad event signals, audience segment data, and downstream propagation to RTB partners. Key DPIA considerations: (1) advertising cookies require consent; (2) RTB bid stream propagates personal data to many independent controllers; (3) US transfer triggers Chapter V; (4) joint controllership with downstream partners; (5) data minimisation through bid stream is difficult. A full DPIA is recommended. ### Sample text for your banner > With your consent, this site uses Mile.tech and partner advertising networks to deliver, measure and personalise advertising.
