GDPR and ePrivacy are different regulations. Under the latter even purely local data storage still requires consent unless it's "strictly necessary" to implement something the user has requested.

For example, see the discussion the sibling commenter linked around storing UI customization choices for only the duration of the current session: https://ec.europa.eu/justice/article-29/documentation/opinio...

You don't need consent in this case, as clearly stated in 3.6 UI customization cookies

3.6 UI customization cookies

These customization functionalities are thus explicitly enabled by the user of an information society service (e.g. by clicking on button or ticking a box) although in the absence of additional information the intention of the user could not be interpreted as a preference to remember that choice for longer than a browser session (or no more than a few additional hours). As such only session (or short term) cookies storing such information are exempted under CRITERION B
