Avoid this kind of useless shop-savings extensions that in facts can spy what you are looking on the internet, it's just collecting informations on you to profile you and similar customers to finally target ads/products/services. That's desguished spyware in counterpart to provide you a pretended nice service for free.

And just about the service provided: this kind of extensions (lots of similar exist like this one) can modify the webpages on-the-fly and also can censure some parts or search results to guide you to buy to a specific shop... instead of a concurrent. And guess who is paying the extension editor to do that? Sellers?
Just look at what this extension is requiring at the Permissions part...

Mind again before adding browser extensions!

I love what UCapture is doing! It's the best way to cover your carbon footprints at no cost to you! Highly recommend it!

UCapture is an amazing way to fight climate change while also saving money! It is so easy to use and not intrusive at all

UCapture is really easy to use! My favorite part is that while not in use, there's no constant nagging like other promotions/extensions. Download it and let it be, and you'll be doing your part to offset carbon!

The extension doesn't slow down your computer or give you any unwanted pop-up ads or viruses. Everyone shops online so why not help save the planet while doing it! It's so easy to do and there are no down sides.

Love this. I get to offset the carbon emissions of my shopping for free? And save money automatically...wow. Happy user here!

UCapture is fantastic! I've wanted to be carbon neutral for a long time, but hadn't found a way without spending a lot of money. This extension helps me achieve my sustainability goal in a really easy and totally free way. Plus their automatic coupon feature has saved me a bunch of money. I highly recommend everyone use this extension!

Very simple to use and it's free. I am able to have some coupons here and there to save money as well as fund projects that help out the environment. I also enjoy the aspect out tracking how much carbon I remove from the planet on their website. But overall it is an easy to use extension
