This domain hosts a niche editor for Taiko no Tatsujin chart files, a Japanese rhythm game. It's clearly a personal project: there's no company behind it, no contact info, and no legal pages — all of which is normal for a free tool shared among fans. The SSL certificate is valid and uses modern encryption, but the site loads 19 external scripts, which is unusually high for a simple editor and could mean third-party trackers or libraries. It also still accepts older, insecure TLS versions, a sign the server wasn't hardened. No blacklists or malware flags have been reported, and the site has no history in the Wayback Machine, suggesting it's new. If you're just editing beatmaps, the risk is low — but avoid entering any personal information, and consider using a browser extension that blocks unwanted scripts. For a community tool, it's not obviously a scam, but it's built more for convenience than security.
