Hi,

You can configure Matomo [1] to both not use any cookies [2] and to automatically delete just the raw data or all data that is older than x months. Log Analytics is also possible.

If you want something that is far more minimalistic, but also Open Source and self-hostable, you can take a look at [3]. (Not sure about how they use cookies)
