Irys is a geolocation data broker that sells precise location data tied to mobile advertising IDs. There is a dedicated "Irys Privacy Portal" / privacy rights request form (linked from the policy text, and a "Do Not Sell My Personal Information" link in the site footer), but you can also just email privacy@irys.us or write to their New York address. Expect to have to prove your identity: they ask for your device advertising ID (AAID or IDFA) plus a utility bill or similar document showing your address. No response deadline is stated, so assume the statutory ~45 days; note they keep a 5-year archive but say they will filter you out of future studies and sales.
