No I think you are mistaking the mechanism that enables this policy for some kind of Safari magic that tries to detect the purpose of the stored data. https://developer.mozilla.org/en-US/docs/Web/API/Storage_API/Storage_quotas_and_eviction_criteria#proactive_eviction https://developer.mozilla.org/en-US/docs/Web/API/Storage_API... > Safari proactively evicts data when cross-site tracking prevention is turned on. If an origin has no user interaction, such as click or tap, in the last seven days of browser use, its data created from script will be deleted. Cookies set by server are exempt from this eviction. It doesn't matter what the data actually is or whether it is used to track users. Safari deletes it.
