Does anyone know anything about the Glorious Jewel Buddhist Center?

I met a woman from Tinder a while ago and she seems nice and friendly but her whole life revolves around a religious organization named The Glorious Jewel Buddhist Center of the Drikung Kagyu Order of Tibetan Buddhism. They have a website here, but I can't seem to find any information about them in English that isn't from the group themselves.

It's very strange because here in Taiwan they have a well established presence but I can't seem to find anyone locally who's ever heard of them. They have their own restaurants and shops and they even have a Glorious Jewel Buddhist Center Visa card that people can apply for to get special discounts at businesses owned by the group.

She is very much of the belief that the Guru is someone with the answers to life's biggest questions and that we should come to him with all our problems. She also seemed uncomfortable with the idea of me trying to learn more about the Glorious Jewel Buddhist Center from outside sources. I don't have any concrete reason to believe this is definitely a cult, but it giving me vibes. She wants me to visit the temple with her next month, and I am happy to go to a temple, but I don't know what I'm getting myself into and that makes me concerned. Thanks for all the help.

Oh, one more thing, she wanted to know my full name, passport number, and birthdate for insurance purposes before we go. I need to check with some people to learn if that's normal. I have not as of yet given her that information.
