This triggers strict compliance rules that prohibit behavioral targeting, profiling, and personal data collection. ### How it works When a request includes the `coppa` flag, DSPs must: 1. Ignore identifiers: Do not read IDFA, Google Advertising ID, or cookies. 2. Disable tracking: Do not store user data for future retargeting. 3. Switch to contextual targeting: Select ads based only on app content, such as serving an ad that features building block toys inside a kids' game. ### Examples **Bid Request** The `coppa` flag is passed in the `regs` object (regulations). ``` json { "id": "req_12345", "imp": [{ "id": "1", "banner": { "w": 320, "h": 50 } }], "device": { "ua": "Mozilla/5.0...", "ip": "192.168.1.0" // IP address is typically masked (last octet zeroed out) }, "regs": { "coppa": 1 }, "user": { // The id, buyeruid, and eids fields should be absent or empty } } ``` **Bid Response** DSPs usually don't need to return the `coppa` flag in their response (they only have to comply with it). However, they can pass an extension in `ext` if the exchange's protocol requires proof of compliance. The response looks standard, except that any tracking pixels collecting personal data are prohibited. ``` json { "id": "req_12345", "seatbid": [{ "bid": [{ "id": "bid_987", "impid": "1", "price": 1.5, "adm": "...ads without tracking..." }] }] } ``` Yandex DSP supports the COPPA (Children's Online Privacy Protection Act) signal.
