Hosting & Database
The server, database, and backups that store every kanji you've collected and every streak you've earned cost money every month, whether ten people log in or ten thousand.
Help Keep LUNA Running
LUNA is free for everyone and built by a small team that pays the bills out of pocket. If it has helped you learn kanji, a donation goes straight back into keeping the lights on.
Where the Money Goes
Email Delivery
Verification emails, lesson reminders, and account recovery all run through a paid email service. Without it, new players couldn't even finish signing up.
New Content
Adding new kanji sets, quiz types, and themed worlds takes real development time. Donations help fund the hours that go into building what comes next.
Keeping It Free
Every donation means LUNA can stay free and ad-free for the people who can't pay, instead of putting core features behind a paywall.
Every Bit Helps
There's no minimum and no pressure. Whatever you can give helps LUNA stay online for the next person trying to learn kanji.
