So #Meta's new #Threads app needs your health and fitness info. It also needs your browsing history and your location, and your purchases, and...well, it seems to need everything. If you want to get fully creeped out, here's the whole #privacy policy: https://privacycenter.instagram.com/policy/.
Meta Privacy Policy - How Meta collects and uses user data

Learn how we collect, use and share user data to support Facebook, Instagram, Messenger and more. Use tools to manage your privacy preferences.

@protonmail Why? Because they can and user concedes to it. Depending on the buyer, Meta, remember Threads checks your Instagram and Facebook pages, sells access to users' data or sells the data. You're the product. Threads, or Instagram, is the candy for users while they're stealing your privacy.
