Not at all. Since you're buying the device through a loan (not a lease), it's fully yours, including everything on it. We don’t access, collect, or claim any rights over your data or intellectual property.
Even if it were a lease, U.S. privacy laws (like the Computer Fraud and Abuse Act and various consumer protection laws) prohibit us from accessing, collecting, or claiming any rights to your personal data or intellectual property. Your files, projects, and information stay completely private.
