Terms of use

These terms cover Cadenvia : Mandarin Journey only.

Learning service

Cadenvia provides educational practice, not a certification, translator, medical service or guarantee of proficiency. Levels A1–C2 describe product progression and are not an official equivalence with HSK or another standard.

Account and acceptable use

Keep access credentials secure. Do not abuse, scrape, reverse engineer, bypass subscriptions, attack services or submit unlawful content. We may limit access needed to protect users and the service.

Subscriptions

Eligible new subscribers may receive a 7-day free trial when the store displays it before purchase. After the trial, the selected monthly or annual plan renews automatically at the binding localized price shown by the store until canceled. StoreKit or Google Play determines eligibility; an ineligible or previously subscribed account receives the regular plan without a trial. The store manages billing, renewal, cancellation and refunds under its rules. Deleting an account does not cancel a store subscription.

AI and speech feedback

Feedback can be incomplete or wrong and must be treated as guidance. It does not award levels, XP, mastery or entitlement. Tone feedback is not a certified assessment and must not be used to discriminate against accents.

Offline and availability

Some study works offline, but authentication, purchase verification, synchronisation, AI and generated audio may require connectivity. Queued actions are not confirmed until accepted by the server.

Changes and contact

Material changes will be dated. Applicable mandatory consumer rights are not excluded. Contact us through support.
