Gradeproof Reviews 

BUYER BEWARE with their seven day "FREE TRIAL" scam! Do not give them your credit card or access to your bank, they will try and steal your money. The product is substandard and they charged me a $119.40 a day early for this crap before I had a chance to cancel. Total frauds and thieves who OUTWRITE lie with the most horrible customer service. I do not recommend, and they have lots of compaints on their G-Suite reviews as well.

Their service is okay, it does its job, though I don't think I've noticed many differences compared to comparable services.

Their customer service is awful. I forgot to cancel my subscription and got charged. I contacted them right away, asking if it was possible to get a refund since I forgot to cancel it, adding that the current pandemic affected me and that would be a significant amount of money for something I don't need right now (at least not for a year).

All I got was a standard answer saying they didn't refund purchases. It was the same exact reply to both of the emails I sent. I am not sure I was talking to a human.

Yes, they can legally do that, but it proves they rely on people forgetting to cancel their trials, an awful, anti-customer practice that only the worst companies on Earth still do. Most companies are more than willing to cancel and give you a refund for a service you don't want.

I would look somewhere else, both as a customer and an investor.
