I don't remember ever giving up my mobile phone number in any registration process. However, I looked at Bolt's "permissions" and they are extensive and complicated and not easy to understand. Many are an undefined "custom." Possibly, therein lies the hole.

Anyone out there have the brains and experience necessary to analyze Bolt permissions in this context? I love the Bolt browser, but if it's distributing personal info, I need to know.

ETA: One category of "Permissions" is "Phone." The default is "Custom."
