Unless your travels are being tracked by the FBI that technology does not exist. Nor do the records. I think there are Apps that will track milage but they have to be installed. Trust in any relationship is built by "WORD - DEED". You say you will do it and then do it! It's also how you end up with a "Profession", most of the time. You are made in the image of G-d with creative power. What you say governs what you do. So carefully watch the words that proceed of your mouth.
