Terms of service

What you can expect from KANJIN, and what we need from you. Written to be read rather than to be impenetrable.

Last updated 1 September 2026

Who these cover

These terms apply to everything at this domain: the free calculators, the local-first back office, the embeddable widgets and the paid KANJIN platform. Using any of them means you accept them.

The free tools are estimates, not advice

The calculators and the back office are planning aids. They make simplifying assumptions and state them on the page. They are not accounting, tax, legal or financial advice, and nothing they output should be the only basis for a decision that matters.

We work hard to make the arithmetic correct and it is covered by automated checks, but you are responsible for the figures you type and for what you do with the answer.

Creator discovery and YouTube

Creator discovery is built on YouTube API Services. By using it you also agree to be bound by the YouTube Terms of Service.

Information Google collects through those services is handled under the Google Privacy Policy. Our own handling is set out in our privacy policy.

Discovery surfaces channels that are already public. It does not give you a relationship with anyone — how you approach a creator, and whether they want to hear from you, is entirely between you and them.

Email to your customers, and who is responsible for it

KANJIN sends by email only — there is no text messaging on the platform. When a message goes to one of your customers, you are the sender in law, not us. We provide the tooling; the obligation to have permission sits with the business whose name is on the message.

Dropping SMS removes one set of rules and leaves another in place. Email is regulated differently, not less:

  • In Canada, CASL covers commercial electronic messages including email, requires consent, and carries penalties up to CAD $10 million for an organisation.
  • In the UK and EEA, marketing email needs a lawful basis under the GDPR and, in most cases, prior consent under the ePrivacy rules. Consent must be a positive action — a pre-ticked box is not consent.
  • In the United States, CAN-SPAM does not require prior consent for commercial email, but it does require a working unsubscribe honoured within ten business days, a real physical postal address, and a subject line that does not mislead.
  • Consent to one thing is not consent to another. Somebody giving you their address for a receipt has not agreed to receive promotions, and you cannot infer the second from the first.
  • A receipt is transactional; a review request or an offer is marketing. KANJIN treats them differently and will refuse to send the second without the separate permission recorded against that customer.

So: collect the permission separately and explicitly, keep a record of when and how it was given, and do not upload a list gathered for another purpose. If you are unsure whether you have consent, you do not have consent.

Acceptable use

  • Do not use KANJIN to collect fake reviews, to offer payment in exchange for a specific rating, or to suppress honest negative feedback. Doing so breaches Google’s policies and will get your listing penalised long before we notice.
  • Do not use the review-reply writer to publish text you have not read. It goes out under your name.
  • Do not scrape, resell or redistribute creator data taken from the platform.
  • Do not use the embeddable widgets to imply KANJIN endorses your business.

We may suspend an account that does any of these, and we will say why.

If your use of KANJIN causes a claim

You agree to indemnify us — to cover claims, fines and reasonable legal costs — where they arise from how you used the service — messages sent without the consent required above, a customer list gathered or used improperly, an offer you did not honour, or content you published through KANJIN that infringed somebody's rights.

This is not us disclaiming our own mistakes. If the fault is ours — the software did something it should not have — it stays ours. This covers the reverse case, and it exists because the obligations above genuinely sit with you and the penalties attach to the sender, not the tool.

Paying, cancelling and refunds

The free tools need no payment and no account, so nothing here applies to them.

  • Paid plans are billed monthly per location and renew automatically until you cancel. Before you pay we will show you the price, the billing interval, that it renews by itself, and how to stop it — on the checkout page itself, not in a linked document.
  • You will get that in writing again after you subscribe, with the cancellation instructions repeated.
  • Cancel online, from inside your account, in as few clicks as it took to subscribe. We will not make you telephone anyone or send an email to a person who answers slowly. Your access runs to the end of the period you have paid for, and nothing further is taken.
  • We will tell you before any price change takes effect, and you can cancel rather than accept it.
  • If you are a consumer in the UK or EEA you have a statutory right to cancel within 14 days of subscribing. Where you ask us to start the service immediately, that right may be reduced in proportion to what you have used — we will not argue about small amounts.
  • If we get something badly wrong, ask. We would rather refund somebody than keep money from a person who feels cheated.

Billing is not switched on yet, so nothing above is currently charging anyone.

Embedding the calculators

The widgets are free to embed on any site, including commercial ones, with no attribution required. We may change or retire a widget; if we do, an embed will keep rendering whatever it renders at that point rather than breaking your page. Please do not modify them to change the arithmetic and continue presenting them as ours.

Your data and your account

Your figures, your customer list and your invitation records are yours. The back office exports to a file at any time. If you close a platform account we delete its records on request — see the privacy policy.

Where you hold customer records with us, the agreement that governs them is the data processing agreement, and every company that receives any of it is named on the subprocessors page. Any customer can be exported as a file or deleted completely, by you from your customer list or by them from their own card.

Availability and liability

The free tools are provided as they are, without warranty. They run in your browser, so they keep working whether or not we do.

For the paid platform we aim for continuous availability but do not promise it. To the fullest extent the law allows, our liability for any claim relating to the service is limited to the amount you paid us in the twelve months before the claim, and we are not liable for lost profits or lost business.

Some things cannot be excluded and we do not try to: death or personal injury caused by our negligence, fraud, and anything else the law of your country does not permit us to limit. If you are a consumer, your statutory rights are unaffected by anything in these terms.

Changes, law and disputes

We may update these terms. The date at the top changes when we do, and where a change materially affects you we will say so before it takes effect rather than after. Continuing to use KANJIN then means accepting it; if you would rather not, cancel.

These terms are governed by the laws of Taiwan (Republic of China). If you are a consumer, this does not deprive you of the protection of the mandatory law of the country you live in, and you may bring proceedings in your local courts.

Before anyone involves a court, write to us. Almost everything is a misunderstanding that survives one email, and we would rather answer it than litigate it. Questions go to hello@kanjin.app.
