A lot or a little?
Parents need to know that Algebra Touch is an educational app that teaches and allows practice of procedural algebraic concepts. Kids learn to drag and rearrange single-variable polynomials so that like terms are together for easier adding. Then kids can tap the operator between the terms to compute answers. Terms can be factored or combined until the variable is isolated. Kids (or parents) can also create their own problems to rearrange and solve. The app saves the problems that were created for later use. Kids can contact others via email or Facebook to get help with problems. There's not much information in the privacy policy, which states that the app collects nonpersonal information.
