Privacy

What haruhime.moe keeps: your haruhime account (your osu! profile and sign-in sessions) once you sign in, and Vercel's request logs. No analytics, nothing sold.

Last updated

haruhime.moe holds your haruhime account: one osu! sign-in for packs, pools and bb. Browsing needs no account, and a visitor who never signs in gets no cookies. The site runs no analytics and sells or shares nothing.

What we store

  • Your haruhime account, if you sign in. Your osu! ID, username, avatar and country from osu!, kept so one sign-in works on packs, pools and bb. No osu! password or osu! tokens are kept.
  • Your sign-in sessions. Each signed-in device's session, with when it signed in, its browser's user agent and IP address, so you can see and sign out your devices on /account. A session ends 30 days after you last use it.
  • Cached library stats. Versions, download counts, stars, releases and READMEs for the Libraries pages, fetched from npm and GitHub by our server about once a day; your browser never contacts npm or GitHub for them, so neither sees your visit.

Cookies

  • Only once you sign in. A short-lived cookie while sign-in runs.
  • A session cookie lasting until 30 days after you last use haruhime.moe or one of its tools, shared by every *.haruhime.moe tool.
  • haruhime-signed-in, which pages can read. It only says this browser may be signed in; pages ask who you are only when it's there.

Service providers

  • Vercel hosts the site and keeps standard request logs for security and operations.
  • MongoDB Atlas stores the haruhime accounts and their sessions.
  • osu! (ppy Pty Ltd) confirms who you are when you sign in with osu!.

Each tool has its own policy

#

The tools run on their own subdomains and keep what you make there (packs, pools, saved BBCode) in their own databases. Each has its own privacy policy, which applies there instead of this one:

Your rights under GDPR and CCPA have their own page.
