Withdrawal Information

The German version is authoritative. Deutsch

For contracts for digital content (purchases in the NixStein app).

Right of withdrawal

You have the right to withdraw from this contract within 14 days without giving any reason.

The withdrawal period will expire after 14 days from the day of the conclusion of the contract.

To exercise the right of withdrawal, you must inform us (Victor von Rautenberg, Pfarrer-Theile-Str. 97, 13591 Berlin, Germany, email: admin@ai-design-thinking.de) of your decision to withdraw from this contract by an unequivocal statement (e.g. a letter sent by post or an email). You may use the attached model withdrawal form, but it is not obligatory.

You can also declare the withdrawal using the “Withdraw from contract” button on this page or in the app (Settings); you will receive an acknowledgement of receipt by email immediately.

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

Effects of withdrawal

If you withdraw from this contract, we shall reimburse to you all payments received from you, including the costs of delivery (with the exception of the supplementary costs resulting from your choice of a type of delivery other than the least expensive type of standard delivery offered by us), without undue delay and in any event not later than 14 days from the day on which we are informed about your decision to withdraw from this contract. We will carry out such reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

Early expiry of the right of withdrawal

In the case of a contract for the supply of digital content not supplied on a tangible medium, the right of withdrawal expires if we have begun performance of the contract after you have expressly consented to our beginning performance of the contract before the end of the withdrawal period, and have acknowledged that you thereby lose your right of withdrawal once performance of the contract has begun, and we have provided you with a confirmation of the contract (§ 356(5) BGB (German Civil Code)).

The app obtains the consent and acknowledgement before the purchase (a tick box before payment). You will receive the confirmation of the contract by email.
