- Access code: the code, with the company name and VAT number of the order and the LEI the code is bound to. We use them to sign you in and to link the code to its payment. Basis: performance of the contract.
- Support: the emails you send us. We use them to answer you. Basis: performance of the contract and our legitimate interest in helping customers.
- Security and logs: IP addresses and technical request data. We use them to run the service and to block abuse, such as repeated failed sign-ins. Email addresses and access codes are masked in logs. Basis: our legitimate interest in a secure, working service.
Workbook content is processed on the customer's behalf and is governed by the DPA.
