Is BOLMOL part of Google or Microsoft?

No. BOLMOL.com is not a partner of, and is not part of, Microsoft or Google in any way. We use Google and Microsoft sign-in because they are the two most widely trusted identity providers, and we hand the credential exchange to the provider directly. We never store your Google or Microsoft login information. For details on how those providers handle your credentials, read the Microsoft OAuth policy and the Google OAuth policy on their websites.
