Do it yourself
- Write to privacyrequests@wunderkind.co from the email address you want removed. Use the sample text below; it cites the laws and lists what to delete.
- Watch your inbox, including spam, for a verification email and click it.
- If they ask for cookie or device identifiers or a signed affidavit, reply with what you can; the email address alone is usually enough.
- Note the date you sent it. Wunderkind says it responds within 45 days. If nothing comes back, send a follow-up citing that deadline.
What to expect from Wunderkind
- Expect an email asking you to confirm. The request is not processed until you click it or reply.
- They may ask for screenshots of cookie IDs or mobile advertising IDs.
- They may ask for a signed affidavit before acting on device or cookie identifiers.
- They require signed authorization before accepting a request from a third party, so sending it yourself avoids a round trip.
- Wants the email address plus any cookie IDs or mobile advertising IDs you can find; digital identifiers are verified with an affidavit. They email you to authenticate the request.
What to say
Copy this, fill in the brackets, and send it from the address you want removed. Shield fills it in for you and tracks the reply.
Subject: Deletion and opt-out request (personal data) - [Your full name]
To the Privacy Team at Wunderkind Corporation: I am a resident of California. I am submitting this request myself, not through an agent. I ask Wunderkind to: 1. Delete all personal information you hold about me, including identity-graph and visitor-identification records, hashed identifiers, and any records obtained from or shared with partners, and to direct your service providers and contractors to do the same; 2. Stop selling or sharing my personal information, including for cross-context behavioral advertising and visitor identification, and record a permanent opt-out; 3. Confirm in writing what categories of personal information you held about me, the sources, and the third parties you disclosed it to. I make this request under: - the right to delete under Cal. Civ. Code § 1798.105 - the right to opt out of sale and sharing under Cal. Civ. Code § 1798.120 - the right to know under Cal. Civ. Code § 1798.110 - the Tex. Bus. & Com. Code ch. 541 (Texas Data Privacy and Security Act), to the extent you process data about Texas residents The identifiers you may use to locate my records are: Name: [Your full name] Email: [the email address you want removed] Phone: [your phone number, optional] Mailing address: [street address], [city], CA [ZIP] State of residence: California Please use this information only to verify and fulfil this request.

Questions people ask
- Why did a store email me after I visited without signing up?
- The store runs Wunderkind's pixel. When you load a page, the pixel matches your browser to an identity graph built from past sign-ups, data-broker lists and cookies, and hands the store your name and email. The store then emails you as if you had opted in.
- Is it legal to make Wunderkind delete my data?
- Yes. California residents have the right to delete (Cal. Civ. Code § 1798.105) and to opt out of sale or sharing (Cal. Civ. Code § 1798.120); Texas residents have equivalent rights under Tex. Bus. & Com. Code ch. 541 (Texas Data Privacy and Security Act); most other states with privacy laws grant the same. Many brokers honor requests from any US state as a matter of policy.
- How long does Wunderkind take?
- Policy: confirms receipt within 10 days, fulfils within 45.
- Will they come back?
- Often. Identity graphs are rebuilt from new data, so a deleted record can reappear months later. Re-filing every 90 days, and detecting when the pixel fires again, is what keeps you out.
