Terms of Use

Effective 2026-06-11. Applies to hako.to and every tool under it.

hako.to and the tools published on it are provided as-is, free of charge, for personal use and study. By using the site you agree to the following terms. They are short on purpose.

Use of the site

You may use hako.to for any lawful purpose: practice, reference, calculation, play. There is no fee, no account, no licence. Educational and personal use is the design target.

Things you must not do

No warranty

The service is provided "as is" without warranty of any kind, express or implied. We make no guarantees about uptime, accuracy, completeness, or fitness for any particular purpose. The reference content (the kana guides, the calendar explainers, the chord charts, the unit-conversion notes, etc.) is offered as a helpful starting point, not as authoritative advice. Verify anything important — medical, legal, financial, exam-relevant — against a primary source.

Limitation of liability

To the maximum extent permitted by applicable law, hako.to and its operator are not liable for any direct, indirect, incidental, special, consequential or punitive damages arising from your use of the site, including but not limited to lost data, lost time, or decisions made based on the content here.

Third-party content

Some pages display advertisements served by Google AdSense. We do not control the content of those ads and are not responsible for the advertisers or the products and services advertised. See the Privacy Policy for details on the ad provider.

Intellectual property

The site's design, text and code are the property of the operator unless otherwise noted. You may quote and share short excerpts with attribution and a link back to the original page. Wholesale copying is not permitted.

Changes

These terms may change. Continued use after a change constitutes acceptance. Material changes are summarised on the changelog page.
