Termination of a contract: Kündigung (notice of termination) or Widerruf (withdrawal). Differences

This is the termination of a contract at the initiative of one of the parties, in accordance with the terms of the contract. That is, if there is a 1-year contract, in order to prevent it from automatically renewing for another 1 year, you need to “kündigen” it, i.e., express your wish to terminate it.
