This website uses Heion's first-party analytics to count browser profiles and repeat visits. A random identifier is saved in this browser and hashed separately for each domain. We do not collect names, IP addresses, account identifiers, page URLs, referrers or message contents in this tracker.
On the mahjong websites, existing visible gameplay heartbeats also measure sampled playing minutes and repeat playing days. Website visitors and playing installations are counted separately. Reinstalling or clearing storage creates a new identity.
Daily activity is kept for 90 days, playing minutes for 14 days and inactive identity records for up to 180 days. Reports sent to the owner contain aggregate counts only. Do Not Track and Global Privacy Control disable collection.
