Terms of service

Effective date: 27 August 2026

By using HanFlow, you agree to these terms. If you do not agree, do not use the application.

Learning tool

HanFlow provides educational practice and automated feedback. Generated explanations, pronunciation assessments, translations, and handwriting assessments can be imperfect and should not be treated as professional certification.

Your data and accounts

You remain responsible for your Google account, configured AI-provider accounts, API charges, backups, and device security. You may use HanFlow without connecting any account.

Advertising

HanFlow is free and funded by advertising. Your first 50 questions carry no advertising, and after that your first 20 questions each day carry no advertising. Advertising may appear once those allowances are used.

HanFlow sells nothing. There are no in-app purchases, subscriptions or paid tiers, and no payment is ever required to use any part of the app.

Acceptable use

Do not use HanFlow to violate law, interfere with services, bypass provider limits, or access another person's data without authorization.

Availability

HanFlow is provided as available, without a guarantee that every device, speech engine, AI model, or third-party service will remain compatible or continuously available.

Changes

These terms may be updated as HanFlow changes. A revised effective date will identify the current version.
