Privacy Policy for Web Forms That Are Not Registered in the Database

I create a website for a local business with the help of a simple contact form.

If the form information is simply sent to an email address such as test@hotmail.co.uk and is not stored in a database, no personal data is collected and stored?

Try to understand if I need to mention that people's data is collected via a simple form but not stored.

Therefore, could I just say:

Privacy policy:

We do not store your data.
