5.3 Purpose and legal basis

The information is used only to identify you, assess your need, reply and follow up, and where necessary arrange a technical contact. The legal basis is your consent (Article 13(1)(1) of the Personal Information Protection Law) and, once cooperation is contemplated, the necessity of concluding and performing a contract.

5.4 Processing and retention

This is a static website. The form is transmitted by your own email client directly to the Company's mailbox; the web server does not receive or store what you submit. Once the message reaches the mailbox, it is retained as follows:

• Enquiries that do not lead to cooperation: deleted within 24 months of the last contact;
• Records relating to concluded business: retained for the periods required by the contract and by accounting and tax archiving rules.

5.5 Sharing, processors and cross-border transfer

• We do not sell or rent your personal information and do not provide it to unrelated third parties.
• We disclose only where: you have given separate consent; it is necessary to perform a contract (for example, a joint delivery partner); or the law or a regulator requires it.
• Where an enquiry involves an overseas partner and your information must be provided to them, we will inform you in advance of the recipient, the purpose and the categories of information, and obtain your separate consent.

5.6 Your rights

Under the Personal Information Protection Law you may access, copy, correct, supplement and delete your personal information, withdraw consent, restrict processing, and ask us to explain our processing rules. To exercise these rights, email the address below; we will reply within 15 working days of receiving and verifying the request. Withdrawal of consent does not affect processing already carried out; after withdrawal we will stop the relevant processing, which may mean we can no longer respond to your enquiry.
