Adds no noise at all. Only use this for non-sensitive fields, and only for metrics from UMA opt-in users. The most common amount of noise, suitable for most fields. Reduced noise, suitable for metrics which receive limited reports (less than 500,000 per day) or expect a highly skewed/sparse distribution over a wide set of domains. Approval from the Chrome Privacy and Rappor teams is required to implement a metric using this noise level. Stricter parameters for metrics collected from a broader population. Deprecated parameters for collecting the domain and registry of a URL from UMA opt-in users. Should use UMA_RAPPOR_TYPE instead. Parameters for collecting the domain and registry of a URL from UMA opt-in users, using SPARSE_NOISE. Intended for sparse/skewed metrics, or low frequency metrics (less than 500,000 reports per day). Explicit approval from the Chrome Privacy and Rappor teams is required to use this type. New metrics should also consider LOW_FREQUENCY_UMA_RAPPOR_TYPE instead.
