What it is
Kozaru is web-based management software for martial arts schools, covering students, attendance, gradings, bookings, and fees. Schools can create belt ranks and grading rules, with readiness based on attendance and time at a rank. Attendance insights compare visits with each student’s usual pattern and flag possible changes. The system supports class bookings, waitlists, and tablet-based kiosk check-in. Parents and students can use a school-branded web app installed from a link, without an app store download. Member payments run through the school’s own Stripe account; Kozaru says it neither holds those funds nor takes a percentage of fees. Timetable and instructor pages can be embedded in Wix, Squarespace, and WordPress sites, and Google sign-in is supported. App notifications are free; text messages cost 10c each and honor STOP replies. Kozaru says school records are encrypted with a school-specific key, its servers are in Melbourne, and encrypted backups are kept in three tiers for up to a year. The free plan follows a 30-day trial and supports up to 20 active students. Its paid Kozaru plan costs A$11 a month for the first 20 active students, then $1 per student from the 21st.
