Terrible

To sign a document just once, you’re forced to create an account and input your cc info. This guarantees a free trial. But when you try to cancel it, it’s impossible. Typing out the process requires a a full days work. To keep it short, don’t use

Good for schoolwork

This App is good for schoolwork (especially English for me)
However the colours in the highlight/draw do not automatically save upon changing which is really annoying because I would like to have the 3-4 colours saved so that I can apply the colour scheme even if I do not finish the annotations in one go
Overall nice app - but could do with some minor improvements

Actual Thieves

This is the worst decision you can make. This service costs $30 and they do not let you cancel it. I have tried probably 10 times now and contacted customer service. They tell me it is cancelled but I still get charged $30 a month. You would have more fun and get more use out of lighting $360 on fire once a year. The people who run this company should serve time.

Response from developer

Hi there, I'm sorry to hear about your experience. I would be happy to look into this for you. Please contact me on ella.james@luminpdf.com and I can look into your account and charges to cancel. I look forward to hearing from you.

They stole my private data.

Don't upload anything, they also withdrew money from my account without my permission.

Works Great

Does exactly what I need.
