Most of the offers available in Instant Earn are free and they do not require any investment. However, some offers from Peanut Labs/ Fyber may imply trials of the respective apps. In this case, it is entirely up to you to cancel the trial in time and not get debited. Other apps require in-app purchases, displayed upon starting to complete an offer and it is entirely your choice to do so or not. We do not assume responsibility for what other apps you want to try, might charge or not.
