DojoBase was built for small and mid-sized karate dojos that are tired of juggling spreadsheets, paper sign-in sheets, and payment notebooks. It gives you a complete picture of your dojo -who showed up, who paid, who's ready for their next belt -without paying for another subscription you don't need.

Everything Your Dojo Needs, Nothing It Doesn't
Complete Dojo Management Software. One-Time Price. Your Data Stays Yours.
Student Profiles
Store everything about each student in one place — contact information, parent and guardian details, date of birth, belt rank, enrollment date, student type, practice days, and internal notes. Search, filter, and export your full roster in seconds
Attendance Tracking
Take attendance for every class in under a minute. Check off who showed up and DojoBase records the rest. Review any past date, and export the full attendance history to Excel whenever you need it.
Belt Ranks & Promotions
DojoBase comes pre-loaded with a full rank ladder from 10th Kyu through 10th Dan, including belt colors and promotion requirements (Dojo can edit to match needs). Promote students individually or in bulk after an exam. Every promotion is logged with a date so you have a permanent record.
Belt Exam Management
Schedule belt exams, assign candidates, set target ranks, record results, and keep a full exam history. Link exams to your calendar so everything stays in one place.
Calendar & Events
Keep your class schedule, belt exams, tournaments, and events on a shared calendar. Everything in one view so nothing gets missed.
Inventory & Gear Sales
Track uniforms, gloves, belts, and any other equipment you carry. Set low-stock alerts so you never run out unexpectedly. Sell items directly from the inventory screen and the payment is logged automatically.
Record tuition, registration fees, exam fees, and equipment sales. Filter by student, payment type, method, or month. See your monthly total at a glance on the dashboard. When you sell gear from inventory, the payment record is created automatically — no double entry.

Reports & Excel Exports

Let assistants and instructors log in with a staff account. Staff can take attendance, record payments, and sell gear — without access to sensitive reports, settings, or the ability to delete records. You stay in control.
Audit Log
Every sensitive action in DojoBase is logged — payments recorded or deleted, inventory sold or removed, students deleted. Admin-only access. Export the full log to Excel for accountability or bookkeeping.
English & Spanish and White Background Too
Toggle between English, Spanish or white background at any time. Every label, button, and screen in the app responds instantly.

Privacy & Data Ownership
Your Data Stays on Your Computer
DojoBase runs entirely on your machine. Student records, attendance, payments — all of it is stored locally in a database on your computer. Nothing is sent to our servers. Nothing is shared with third parties. You own your data, period.
No cloud means no subscription fees, no data breaches from someone else's server, and no worry about what happens if your software company shuts down. Your database is a single file you can back up, move, or restore at any time.
Track uniforms, gloves, belts, and any other equipment you carry. Set low-stock alerts so you never run out unexpectedly. Sell items directly from the inventory screen and the payment is logged automatically.
