  • Pseudonymization and tokenization of certain categories of your Personal Data;
  • Protection of data integrity;
  • Encryption of your Personal Data in transit and in rest;
  • Organizational and legal measures. For example, our employees have different levels of access to your Personal Data, and only those in charge of data management get access to your Personal Data and only for limited purposes required for the operation of the App. We impose strict liability on our employees for any disclosures, unauthorized accesses, alterations, destructions, misuses of your Personal Data.

We also commit to undertake privacy audit in case of Company’s merger or takeover.
