Dark Pattern Contract & Subscription Exit Lawyer
Paste a contract or Terms URL and get the decision first: send notice by a computed date, or the window has passed. Quotes auto-renewal, notice-window and early-termination traps verbatim, computes the renewal and last-notice dates in code, estimates the renewal cost you avoid from your fee, maps the exit to ROSCA, state automatic-renewal laws and EU/UK consumer law with links, and drafts a notice with its placeholders listed. General information, not legal advice.
What you get
A missed 60-day notice window on a gym, SaaS or telecom plan locks in another full term, often $500 to several thousand dollars for consumers and far more for business contracts; one caught deadline pays for the call many times over.
