Disclaimers

packs.haruhime.moe ("packs") is an independent fan project. This page says who we're not, how our requests identify themselves, how torrents work here, and what our numbers mean.

packs is not affiliated with, endorsed by, or run by:

• ppy Pty Ltd or osu!;
• the osu! Tournament Committee;
• the hinamizawa beatmap mirror (mirror.hinamizawa.ai).

Not affiliated with or endorsed by ppy Pty Ltd. osu! is a trademark of ppy Pty Ltd.

• Our server to the osu! API. Our server calls the osu! API for maps the mirror doesn't have, for star ratings with mods, and to work out a saved pack's stats. Those requests send User-Agent: packs.haruhime.moe (+https://packs.haruhime.moe; haruhime@haruhime.moe).
• Signing in. Sign-in with osu! runs on haruhime.moe, not on packs. Signing out on packs makes one request from our server to haruhime.moe, carrying only your session cookie.
• Your browser to the mirror. Beatmap files and beatmap data go from the mirror to your browser. Browsers don't let a website set the User-Agent, so these requests carry your browser's own User-Agent, plus the Origin and Referer headers that name packs.haruhime.moe.
• Our server to the mirror. To work out a saved pack's stats, and to list the maps on a saved pack's page, our server asks the mirror for the maps' details (never the beatmap files), with the same User-Agent.

packs was built with help from AI coding tools (Claude, by Anthropic). A person reviews, tests, and ships every change.

• Star ratings with mods. Where packs shows a star rating with mods, it comes from the osu! API and is kept for up to 30 days, so it can lag behind a difficulty update on osu!.
• Pack stats. The star rating, length and BPM ranges on public packs are worked out when a pack is saved. They can lag behind a map update on osu!, and while a lookup fails they cover only the maps we could look up.

Torrents are peer-to-peer: the files come from other people's computers, not from us. packs doesn't host, seed, or track any files. The magnet links on packs are added by pack owners, and we can't check what their torrents contain. You're responsible for what you download and share, and for following the law where you live. If torrenting, or downloading these maps, isn't legal for you, don't do it.

Beatmaps, and the music, art, and video in them, belong to their mappers, artists, and other rights holders. Maps come from the mirror to your browser, and we don't host them. To report a problem, see Copyright & Takedown.
