Which personally identifiable information?
The time of day you use your devices? Which languages you use? Which websites you visit? The type of medical conditions you search for?
Information being PII or non PII isn't binary. It's relative shades of how shannon entropic it is. You need about 33 bits to identify someone, you likely have leaked 33 bits of entropy.
