Just checked Google Play store for the top apps. Only checked the first five but here are their privacy policies: https://www.tiktok.com/legal/privacy-policy?lang=en http://www.cfacdn.com/mobile/apps/fs/shortFormNotice/index.html http://instagram.com/legal/privacy/ https://privacy.thewaltdisneycompany.com/en/current-privacy-policy/ https://m.facebook.com/policy.php I don't know where you are looking but the Google Play Store requires a link to the privacy policy to be listed. Of course you can game the system and just put a link to your website like AG has done. Apparently they don't actually check them.
