  • immediately terminate the Customer's license, software access, technical support, and any associated services without prior notice;
  • refuse any refund, the transaction having already been formally adjudicated by the payment network;
  • refuse any future request to restore access, reactivate the license, or create a replacement account by the Customer or anyone acting on their behalf;
  • retain all evidence, data, and communications related to the account and the disputed transaction for compliance, security, and legal defense purposes, for a period consistent with applicable legal obligations.

Such termination entitles the Customer to no compensation and does not affect the Company's right to pursue further legal action to obtain redress for damages suffered.

We reserve the right to modify these ToU at any time. Users will be informed of modifications by email or via the software.
