Help improve Phynanx

I agree that the sentences I type in the assistant, the questions asked, the buttons clicked and my corrections are kept to improve how Phynanx understands them. These sentences may contain health information (disability, AAH, illness, sick leave, handicap): I expressly agree that they are kept under the conditions below.

Before anything is stored, names, emails, phone numbers, addresses, social security and tax numbers are removed. Sentences are never linked to your account or your device, are dated to the month only, kept for 24 months at most, used only for our test sets and tuning, and never sent to an external model for its training. You can withdraw your agreement at any time by unticking the box. Privacy policy
