We use a privacy compliant mechanism (private set membership) to measure device counts and device churn.
The client deterministically generates a pseudonymous id using a high entropy seed, which is used to send the pseudo-id at most once from the device.
In the future, there are plans to measure user level metrics.
Please note, we represent the device's online timestamp, adjusted to Pacific Time (PST) in the variable |active_ts_|, which is a part of the UseCaseParameters object.
