The language-learning platform that remembers your sweat

Consent document

Consent to MBTI analysis

This is a separate consent document for the feature that lets AI analyze and accumulate personality type (MBTI) indicators in the diary. You can give or withdraw consent in the app under [Settings > Diary > AI Analysis].

Trust and Responsibility

Users decide how much of their learning records are shared, and for minors we apply more conservative default settings. We don’t hide pricing, rewards, or cancellation criteria, and we don’t trap records to prevent people from leaving.

Privacy

You always decide who can see your records. By default, it’s close to “Only me.”

Transparent Operations

Price changes are announced first, with the reason and timing, and canceling stays just as clear and accessible as signing up.

Honest Rewards

There’s nothing you get by luck. It’s exactly as much as the sweat you’ve shed.
