Since 19 June 2026, Article 11a of the EU Consumer Rights Directive requires a withdrawal function on online shops selling to EU consumers; in Germany §356a BGB, in Austria §13a FAGG from 1 October 2026. Cooloff adds it: a labelled button, a short form and an acknowledgement of receipt on a durable medium. A shop's own “Withdraw from contract here” link can open the form instead of a floating button. The label stays readable on any colour you choose. The acknowledgement is emailed with the content of the declaration and the exact time it arrived, plus a receipt file the customer can verify in any browser; the dashboard shows whether it went out and can resend it. You get a copy of each declaration by email; all are listed, exportable and deletable. One click in the dashboard sends you both emails as a test. With a connected store it matches the order, assesses the 14-day period and cancels and refunds in one click, never automatically for a shipped order. It can also place the EU legal-guarantee notice (Regulation (EU) 2025/1960) on your product page. The data processing agreement is on cooloffapp.com. Cooloff does not decide whether a withdrawal is valid and gives no legal advice.
