Language Coach is a language-practice tool provided as-is, without warranty.
The free plan tracks up to 100 words within a small daily allowance. New free accounts are offered only while capacity allows; when free places are full, a new account starts on Premium.
Premium is a recurring Paddle subscription that removes the word limit and raises the daily allowance far above normal practice (fair use). Its 7-day free trial is offered only while capacity allows; when trials are full, the subscription is charged from the first day. It can be cancelled anytime.
When a daily allowance is used up, the coach says so and nothing more is saved until it renews the next day. Don't abuse the service. Questions: contact@poietic.studio.
