Not legal advice. This tool provides general information based on state statutes and the FTC Cooling-Off Rule as of October 2026. Laws change and every contract is different. For advice about your specific situation, talk to a consumer attorney or your state attorney general's office. We can't promise you can cancel — nobody can. What we do: tell you where the cancellation windows are, and what to do when they're closed.
