Terms of Service
Last updated: 2026-08-13
These Terms of Service (the “Terms”) set out the conditions for using the website tanmen.work operated by tanmen (“we” or “us”) and each of the services we provide (together, the “Services”). Anyone who uses the Services (the “User”) is deemed to have agreed to these Terms.
Article 1 (Application)
- These Terms apply to every relationship between the User and us in connection with the use of the Services.
- Where we separately provide terms, guidelines or notices for an individual service (“Service-Specific Terms”), those also form part of these Terms. Service-Specific Terms set out matters particular to that service, such as the permitted scope of use, licence conditions, and prohibitions specific to that service. Where these Terms and Service-Specific Terms conflict, the Service-Specific Terms prevail.
- For services with no Service-Specific Terms, these Terms apply as they are.
- Some of the Services are provided free of charge and some are provided for a fee (“Paid Plans”). For Paid Plans, the statements in the Notation Based on the Japanese Act on Specified Commercial Transactions apply in addition to these Terms.
Article 2 (Accounts)
- For services that require account registration, the User shall register accurate information and update it promptly when it changes.
- The User is responsible for managing their own account credentials and shall not lend, share or transfer them to any third party.
- Acts carried out using a registered account are deemed to be acts of that User. If there is a risk that the credentials are being used by a third party, please contact us promptly.
Article 3 (Use by Minors)
Where the User is a minor, they shall obtain the consent of their legal representative in advance of using the Services, including applying for a Paid Plan.
Article 4 (Fees and Payment)
- Prices and billing cycles for Paid Plans are stated on ~/products. Payment methods, payment timing and the timing of provision are as stated in the Notation Based on the Japanese Act on Specified Commercial Transactions.
- Payments are processed by Stripe. Card numbers are received directly by Stripe; we neither receive nor retain them.
- Plans paid on a recurring basis renew automatically on each service’s billing cycle unless cancelled.
- If we revise our fees, we will give notice on the Services in advance. For plans already subscribed to, the new fee applies from the billing that falls on or after the effective date we announced.
- If payment cannot be confirmed, we may suspend provision of the paid features for the account concerned.
Article 5 (Cancellation and Refunds)
- Plans paid on a recurring basis (monthly or yearly) — You can cancel at any time. After cancelling, you will not be billed again, and you can keep using the service until the end of the period you have already paid for. We do not issue prorated refunds. Where the cause lies with us, such as a payment failure, we will handle it individually.
- One-time purchases — As this is a one-time purchase, there is no cancellation procedure. Due to the nature of digital goods, we cannot accept refunds after purchase. If a defect such as the software not working cannot be resolved, we will handle it individually.
Where a product is treated differently, the statement on ~/products prevails.
Article 6 (Prohibited Acts)
In using the Services, the User shall not do any of the following.
- Acts that violate laws or public order and morals, or that lead to criminal conduct
- Acts that infringe the copyrights, trademark rights or other rights of us or of any third party
- Acts that improperly obtain, use or disclose the personal information of other users or third parties
- Acts that place an excessive load on the servers or network of the Services, or that access them improperly
- Acts that reproduce, modify, decompile or disassemble the Services, or analyse their source code (except to the extent permitted by law)
- Acts that resell, redistribute or lend the Services or any part of them without our permission
- Acts that transfer, lend, share or sell a licence key or other credentials to a third party
- Acts that circumvent the verification of a licence or of subscription status, and acts that publish how to do so
- Acts that exploit defects in the Services or gaps in their specifications to avoid paying fees
- Being a member of organised crime or similar antisocial forces, or providing funds or benefits to them
- Any other act that we reasonably judge to be inappropriate
Article 7 (Responsibilities of the User)
- The User is responsible for the operations they perform using the Services and for the content of the data they enter or store.
- Where the User uses the Services in combination with other services, software or games, the User is responsible for confirming that such use does not breach the terms set by the respective providers. We bear no responsibility for measures taken by those providers, such as suspending or restricting an account.
- For the avoidance of doubt, the software we provide contains no functionality intended to circumvent, or to interfere with the detection of, the anti-cheat or anti-fraud mechanisms of other services or software, and we will not implement any.
- The User shall make their own backups of data stored in the Services as necessary.
Article 8 (Suspension of Use)
If the User breaches these Terms, we may suspend the provision of all or part of the Services, or delete the account, without prior notice. In that case we bear no responsibility for damage arising to the User. This does not apply where we have acted intentionally or with gross negligence.
Article 9 (Changes to, Interruption of, and Termination of the Services)
- We may change the content of the Services or end their provision. Features provided free of charge may be changed or ended without prior notice.
- If we end the provision of a Paid Plan, we will give notice on the Services a reasonable period in advance. Where a period has been paid for but has not yet elapsed, we will refund the amount corresponding to that period. (The statement in Article 5 that prorated refunds are not issued applies to cancellations made for the User’s own convenience.)
- Where there is maintenance of equipment, a response to a failure, or another unavoidable reason, we may temporarily interrupt the provision of the Services without prior notice.
Article 10 (Intellectual Property Rights)
- Intellectual property rights in the Services and in the programs, text, images and designs that make up the Services belong to us or to the rightful holders. These Terms do not transfer those rights to the User.
- Rights in the data the User enters or stores in the Services are reserved to the User. We handle that data only to the extent necessary to provide and maintain the Services.
Article 11 (Handling of Personal Information)
Personal information obtained in connection with the use of the Services is handled as set out in the Privacy Policy.
Article 12 (Disclaimer of Warranties and Limitation of Liability)
- We do not warrant that the Services are fit for any particular purpose of the User, that they have the functions or the accuracy the User expects, or that they will be free of defects.
- Except where we have acted intentionally or with gross negligence, our liability for damage arising to the User from the use of the Services is limited to damage that would ordinarily arise, and we bear no responsibility for damage arising from special circumstances.
- Except where we have acted intentionally or with gross negligence, the amount of compensation we bear in respect of a Paid Plan is capped at the amount paid by that User during the 12 months preceding the time the damage occurred.
- We bear no responsibility for disputes arising between the User and any third party.
Article 13 (Changes to these Terms)
We may change these Terms. Where we do so, we will post the amended content and the date on which it takes effect on this page before that date. If the User uses the Services on or after the posted effective date, they are deemed to have agreed to the amended Terms.
Article 14 (Method of Contact)
Enquiries about the Services, and communications from us to the User, are made through the form at ~/supports/general, or by email to the address the User has registered.
Article 15 (Assignment of Rights and Obligations)
The User may not transfer to a third party, or offer as security, their status under these Terms or their rights and obligations under them, without our prior written consent. Where we transfer the business relating to the Services to a third party, we may, as part of that transfer, cause our status under these Terms, our rights and obligations, and the User’s registration information to be succeeded to by the transferee.
Article 16 (Severability)
Even if any provision of these Terms, or part of one, is held invalid or unenforceable under the law, the remaining parts continue in effect.
Article 17 (Governing Law and Jurisdiction)
These Terms are governed by and construed in accordance with the laws of Japan. If a dispute arises in connection with the Services, the Tokyo District Court shall be the court of exclusive agreed jurisdiction for the first instance.
