Account & Service Control · Restriction or exception
Amazon may cut off your access at any time, without a refund
Amazon may also terminate your right to use the Service at any time, including if it determines your use violates any term of the Agreement or involves fraud or misuse of the Service. Violation, fraud and misuse are examples ("including"), not the only grounds. On such a termination you must stop all use of the Service, and Amazon may immediately revoke your access to the Service without refunding any fees. Because the Service includes Kindle Content, this can mean losing access to content you paid for.

Cross-references
contrast (model-proposed): Kindle Content is licensed, not sold, for limited personal use — contrast: The license is granted once you pay for Kindle Content, yet Amazon may terminate your right to use the Service at any time and revoke access without refunding any fees. The two provisions pull in different directions for content you paid for; this is a reviewed tension, not a legal finding.
