JPP Terms of ServiceTerms for using JPP.
Last updated October 11, 2026. These terms cover the JPP website and app developed by Nerdhook.
Using JPP
JPP provides Japanese language practice, including JLPT style papers, mini tests, answer review, and progress tools. You may use guest paper practice without an account. Saving results and using account features require Google sign-in.
Practice results
Scores, estimates, and progress views are learning aids. They are not official JLPT results and do not guarantee an exam outcome. Question content and features may change as we improve JPP.
Your account
Keep access to your Google account secure. Do not misuse JPP, interfere with the service, or try to access another person's account or results. You can delete your JPP account from the Android app's settings or contact us for help.
Availability and account access
Some features depend on account access set by JPP administrators. JPP may be unavailable during maintenance, updates, or provider outages.
Questions
Contact the JPP team with questions about these terms. See our Privacy Policy for how account and practice information is handled.
