Legal Question in Intellectual Property in Texas

We don't have ESP to know what characters these are and who you are infringing, so we don't know what the reaction will be. A disclaimer does not work. That is like a bank robber saying the bank is not responsible for the robbery. Amazon did not agree your app was fine, they just failed to say it was unacceptable. The action would likely be a DMCA take down request sent to Amazon, which would result in your app being removed from Amazon. You would then have the option of filing a counter-notice claiming it is not infringing and giving your contact information so the copyright owner could sue you, and if you filed that counter-notice then Amazon would put your app back up and the copyright owner would have to get a court order to have it removed. See 17 USC 512. The copyright owner then would have to decide whether to sue you. If they did, the possible damages are $750 - $150,000 per infringement plus attorney fees and court costs and an injunction. Your app is apparently a derivative work as defined in 17 USC 101 and thus infringes the exclusive rights of the copyright owner under 17 USC 102 which makes you liable under 17 USC 501. In other words, you would likely lose the case, so consider those damages carefully.
