Terms of service

What follows is the agreement between you and Kanjido — what you can expect from the product, what you agree to by using it, and how either side can end the arrangement. Kanjido is operated by Giacomo De Marchi from Italy as a free, non-commercial personal project; the terms reflect that scale.

The source material

Kanji frame numbers, ordering, primary keywords, primitive names, and the printed mnemonic stories shown on Kanjido are from Remembering the Kanji, Volume 1 (Sixth Edition)by James W. Heisig, published by University of Hawai'i Press. The book is the canonical work; Kanjido is a companion. If the method works for you, please support the author by buying the book through University of Hawai'i Press.

Community alternative stories shown alongside Heisig's are sourced from the Kanji Koohii community at kanji.koohii.com, where they were contributed by individual learners over many years. Authorship of those stories belongs to their contributors.

Anything you write yourself — the per-frame mnemonics in the Atlas's writing surface, any notes — remains your own. You can export or delete your writings at any time from your account page.

Your account

Kanjido accounts are created automatically the first time you sign in; there is no separate signup step. You can sign in with Google OAuth, Discord OAuth, or an email magic-link via Resend. The identity Kanjido stores is described in the Privacy Policy.

You are responsible for the security of whatever you sign in with — your Google or Discord account, or the email address you used for the magic-link. If your sign-in provider is compromised, your Kanjido account is reachable through it.

Account deletion is available on your account page. Deletion is irreversible: all per-user records — progress, history, mnemonics, sessions — cascade from the user record. The maintainer cannot recover deleted accounts.

Your content

Anything you write inside Kanjido — per-frame mnemonics, notes, future user-contributed content as features add — remains yours. You grant Kanjido permission to display your content back to you across your own sessions; that permission ends when you delete the entry or your account. Kanjido does not republish, syndicate, or display your mnemonics to other users.

If features are added that involve sharing user-contributed content with other users — community- visible stories, public mnemonics, comments — these terms will be updated before the feature ships, and this section will describe the new arrangement plainly.

Acceptable use

A short list of don'ts:

• Don't try to break the service: no vulnerability scans, no automated load tests against production, no scraping behind the authentication wall, no attempts to access accounts that aren't yours.
• Don't harass, threaten, or harm other users (relevant once community features ship; for now the product is mostly single-user).
• Don't use stolen credentials, impersonated identities, or accounts you don't control.
• Don't redistribute Kanjido's content — the rendered Heisig material, the underlying database, the community-contributed stories — as if it were your own work.

The maintainer reserves the right to terminate accounts in clear cases of violation. In ambiguous cases, expect a courtesy email first.

Our role

Kanjido is provided as-is. The product works as described in the editorial copy and the FAQ; the maintainer doesn't promise continuous availability, specific performance, or particular learning outcomes. Heisig's method works for many learners; it isn't guaranteed to work for you, and the maintainer makes no claims about how quickly or completely it will.

Kanjido is maintained by one person as a non-commercial personal project. Updates ship in batches, not on a schedule. If the page goes quiet — vacation, life events, a temporary loss of interest — the product remains available; Edition I (kanji meanings) stays free.

Liability limitation

To the maximum extent permitted by law, the maintainer is not liable for indirect, incidental, or consequential damages arising from your use of Kanjido, including loss of progress, loss of access, loss of opportunity, or loss of time. The product is free; you have not paid for any guaranteed outcome.

For Italian and EU consumers, this limitation does not affect statutory rights you hold under mandatory consumer-protection law.

Termination

You can end your account at any time by deleting it from your account page. Deletion is irreversible.

The maintainer can end your access if you violate these terms (per the acceptable-use list above), if a legal authority requires it, or if Kanjido as a whole shuts down. In the violation case, you'll receive a courtesy email where reasonable. In a shutdown case, advance notice goes out by email to all account holders.

Changes to these terms

Material updates — new features that change your rights or obligations, changes to the source-material acknowledgment, changes to liability or termination — are reflected here when they happen. The effective date below shifts with each change. Where a material change adversely affects your rights, the maintainer will use reasonable efforts to notify registered users by email before the change takes effect. Significant updates sit at the top of this page for a while.

Governing law

These terms are governed by Italian law. Any disputes that can't be resolved by reaching out to contact@kanjido.app will be subject to the jurisdiction of the competent Italian courts.

Questions, concerns, or anything else reach the maintainer at contact@kanjido.app.

Effective: 14 May 2026.
