1.4. Licence and device binding

The licence key is bound to one (1) device: upon first activation, the key is tied to that browser/device (device binding). Transferring, duplicating or publicly sharing the key is prohibited. To move the licence to a new device, contact info@aaa777.eu.

1.5. Liability

Plans, worksheets and AI checks produced by the Service are for informational purposes only; they do not constitute permit-ready design documentation and do not replace the work of a licensed architect or discipline engineer. AI-based recognition and checks may contain errors; final technical decisions are the responsibility of the user or the professional they engage. The Provider does not guarantee uninterrupted, error-free operation but makes every effort to maintain it.

4. Right of Withdrawal

Consumers in the EU have a 14-day right of withdrawal. For digital content, this right is lost once performance has begun with the consumer's express prior consent and acknowledgement that the right of withdrawal is thereby lost (Directive 2011/83/EU, Art. 16(m); Hungarian Gov. Decree 45/2014, §29(1)(m)). Activation of the licence key constitutes the beginning of performance.

If the key has not been activated, you may withdraw without giving reasons within 14 days of purchase by writing to info@aaa777.eu; the purchase price will be refunded within 14 days via the original payment method.
