# Cancellation Navigator > Verified steps to cancel Netflix, Spotify, Prime & more, plus a cancellation letter. Choose a subscription and how you signed up. Cancellation Navigator shows the steps from the official help page (with the date we last checked it), what to do if you are billed through the App Store, Google Play or a carrier, your German online cancellation-button rights (§ 312k BGB), a ready-to-send cancellation letter and a proof-keeping checklist. Part of usefulweb.site (https://usefulweb.site/). Results are deterministic calculations from the inputs and the listed assumptions; the API returns exactly what the web page shows. ## Use it - Human interface: https://cancellationnavigator.usefulweb.site/ (interactive tool at https://cancellationnavigator.usefulweb.site/tool) - JSON API: POST https://cancellationnavigator.usefulweb.site/api/v1/calculate with a JSON object of inputs (schema: https://cancellationnavigator.usefulweb.site/api/v1/tool) - OpenAPI: https://cancellationnavigator.usefulweb.site/openapi.json - MCP (Streamable HTTP): https://cancellationnavigator.usefulweb.site/mcp - tool `cancellation_navigator` ## Inputs - service (select): Service - serviceName (text): Service name (if Other) - country (select): Your country - channel (select): Where did you sign up / who bills you? - yourName (text): Your name (for the letter, optional) - customerNumber (text): Customer / account number (optional) ## Method - Service steps were condensed from each service's official help page on the date shown (verifiedAt); nothing is added that the page does not say. If a page could not be read reliably, only the official link is given (steps not verified). - App Store and Google Play subscriptions are billed by Apple/Google, so the store's own cancellation steps (Apple Support, Google Play Help) are shown first for those channels. - Carrier/partner billing: cancel with the company that bills you (e.g. Spotify's help states partner plans are cancelled with the partner). - Germany: § 312k BGB (Kündigungsbutton) summary from gesetze-im-internet.de. Rights for other countries are not asserted because they were not verified. - Unknown services get a generic method and letter, clearly marked as unverified. ## Limits - Not legal advice. Service flows change; the official page linked is authoritative.
