When you put your brand on a math app, two things have to be beyond doubt: the answers are right, and student data is protected. Kimsa is engineered for both — and tested for both on every change.
Figures from the engine's automated test suite, which runs on every change.
Thousands of generated items are checked automatically for a valid answer key, four distinct options, and no calculator-style decimals — with zero tolerance for hard failures.
Answers are graded deterministically and accept equivalent forms, so a correct answer written differently is never marked wrong — and a wrong one is never accepted.
Each wrong choice maps to one named misconception, so results teach — and every option is validated against that catalog.
The timed exams are locked and regression-tested, so a content change can never silently alter a placement or practice test.
The engine needs no name, email, or personal detail to work. There's nothing sensitive to collect, store, or breach.
Progress lives on the student's device. Cloud sync is optional and privacy-safe.
Sync is union-merge — combining both sides — so a student's history and mastery can't be overwritten or dropped.
A no-PII design makes district and minor deployments far simpler. You control any account layer you add on top.
Kimsa provides the engine and its privacy posture; your legal/compliance obligations depend on how you deploy and what account or billing layer you add.
