EU consumers may withdraw from the purchase within 14 days without giving a reason. See 5.9 for the effect of requesting immediate start (you may lose this right once processing begins).
If we fully performed within those 14 days after your express request to start, the right of withdrawal does not apply to that analysis.
If performance was partial when you withdraw, we may retain a pro-rata amount for the part already delivered.
How to exercise: email support@kirigami.ai with a clear statement. You may also use the EU Model Withdrawal Form.
