BidSwitch is a middleware that allows connected programmatic partners to seamlessly access new platforms and services to optimizing their performance. BidSwitch (owned by Criteo) has no self-service consumer deletion form on this page — you must email your request, e.g. privacy@bidswitch.net or Criteo's DPO at dpo@criteo.com, stating which right you are exercising; they say they respond within 30 days and may ask for information to verify your identity. The policy mentions a cookie opt-out link and a CCPA Privacy Center, but no direct URLs are given in the text, and for data processed on behalf of their ad-tech clients they tell you to contact the client directly.
