Hello User of lColor or gMol!
The apps, only do what they are designed to do: calculate molar mass or the color a wavelength of light will appear. There is no internet communication for anything other than ads in the free version. I do not store any of your personal information and the only information the apps store on your phone relates to the settings you set, or is a consequence of the ad package I installed on the free version.
This is a rookie mistake, but I lost the signing keys to my apps so I am incapable of ever updating any of them. My apologies! Let me know if you have any questions j@josephGoodknight.com.
