Privacy Policy

Overview

Mania Tracker is an osu!mania community site built around public osu! data, cached projections, and user preferences. This policy explains the data used to operate the site.

Data The Site Uses

Mania Tracker uses public osu! profile, score, beatmap, beatmapset, ranking, and replay metadata, plus community data services such as osu! score cache, to build rankings, tracker views, maps, snipes, top plays, farm-helper suggestions, profiles, and replay views.

If you sign in with osu!, the site receives the osu! account details allowed by the identify and public OAuth scopes, such as user ID, username, avatar URL, and country. The site stores a signed HTTP-only session cookie so it can recognize you while the session is active.

The browser stores preferences and caches in localStorage, including theme settings, selected country, hidden users, replay viewer preferences, map filters, and similar client-side state. You can clear this data through your browser storage controls.

Analytics And Logs

If analytics are configured, Mania Tracker may send page views and interaction events to PostHog through the site's sync endpoint. Those events can include route names, selected country, referrer, browser language, screen size, and route-specific identifiers such as a viewed player, score, beatmapset, or maps tab.

The server may process request metadata such as IP address, user agent, timestamps, rate-limit activity, and upstream API call information to operate the site, prevent abuse, debug errors, and monitor service health.

Sharing

Mania Tracker does not sell personal data. Data may be processed by service providers used to run the site, including hosting, storage, analytics, osu! API services, and community score-data services. Public osu! data may be cached and re-displayed as part of the site's community features.

Retention And Controls

Browser preferences and local caches stay on your device until they expire, are replaced, or you clear localStorage. osu! login sessions can last up to 30 days unless you log out earlier.

The server keeps raw score events for about 14 days, live event replay logs for about 7 days, completed background-job records for about 2 days, API call logs for about 7 days, country rank snapshots for about 14 days, and player activity summaries for up to 2 years.

Durable public projections such as rankings, maps, top plays, snipes, cached profile data, and historical aggregates may be kept longer because they are what the site uses to serve those features.
