is this provider recommendable does it share private data with someone/something and do you have any kind of problems with it?

Don't know about the privacy, but i really don't like those capped uploads.

Currently using them, was the fastest provider ive tested so far.
Got like 20TB uploaded off the NVME plan in 4 days, was crazy but keep this in mind, their refund policy is strict you get prorated on the data you use, so basically no refunds unlike competitors.

Have not used their HDD plans, but their NVME blew my socks off.
Recommended.

I have there Scorpio plan, by far the best plan I've used so far, blew rapidseedbox out of the water
