How we use artificial intelligence
The core of THALON is the automatic generation of workout plans through an artificial intelligence system. The data you provide (age, sex, weight, height, level, goal, frequency, any injuries, available equipment) is processed by OpenAI's models (ChatGPT) to generate a personalized workout plan, which is then periodically regenerated taking your progress into account.
This processing involves transferring some of your data, including any health data you have provided, to OpenAI, L.L.C., based in the United States (see the "International transfers" section).
The generated plan is an automated workout suggestion and does not replace the advice of a doctor or a qualified fitness professional; you can always choose not to follow it or to stop at any time.
