In order to make sure I am in compliance with FTC regulations, I am publishing this disclosure page. You the reader need to know that I am making money from this site. I want to be as open and upfront about that as possible. At various times I have used the methods I will describe.

Google Adsense ads should be pretty obvious since they are labeled “ads by google,” but I do also have affiliate links. If you click them and purchase a product, I will earn a commission on that sale. There are a couple of different types of affiliate links on this site. I do have other affiliate links on the site in the form of redirects.  I’ve got them all in the same place, my “go” subdirectory.  That means that any link you see that begins http://www.techpoweredmath/go/ is an affiliate link, including links to Amazon, all of which earn advertising fees. Lucas Allen is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to amazon.com. Additionally, I have experimented with third party products that turn regular links into affiliate links such as Viglink and Skimlinks. Basically, if you follow just about any link from my site to another site that allows you to purchase something, it is likely that there is a tracking cookie that will allow the retailer to pay me in the event that you make a purchase.

Some of the products I review have been loans. Others are products I have purchased. Occasionally, I have even received a product donation as part of the review process. I will mention this during the review if it is the case. Whether the product is purchased, loaned, or donated has no impact on the review I give the product.

As for the impartiality of my reviews, I always do my best to be impartial. I’m not a journalist, just a guy drawing on my years of experience working with students, calculators, and computers. I tend to do a lot of positive reviews. The main reason for this is that I don’t bother reviewing the stuff that I think is crummy or I just include it as a footnote to another review (see the TI-30Xa). I also just think there are a lot of good options out there for students and teachers trying to utilize math technologies from the TI-89 Titanium to websites to plugins.

If you have any questions about any of this, feel free to shoot me an email.
