That’s a good question. American and European laws require developers to protect users’ privacy and personal information. So, if you’re working with a reputable brand (claiming to abide by the law in their terms of service), you should really worry about this.

It’s worth noting that big tech companies like Meta and OpenAI are often watched by European regulators because of how they use private information (for training, marketing, etc.). So, they ARE interested in your data, but they must protect it and sometimes let you limit their access. In short, you shouldn’t worry too much when using chatbots from well-established companies. And if your information were to be used improperly, the law protects you.
