These Terms of Service (the “Terms”) set out the conditions for using Stil (the “Service”) provided by Crop&Kern Co., Ltd. (the “Company,” “we,” or “us”). You must read and agree to these Terms before using the Service.
These Terms apply to all relationships between the Company and customers regarding use of the Service.
If these Terms conflict with descriptions of the Service outside these Terms, these Terms prevail.
Unless otherwise defined in these Terms, the following definitions apply:
A person wishing to use the Service may apply through the Company’s prescribed process after selecting a Plan.
Applicants must provide complete, truthful, accurate, and current information. Applying constitutes agreement to these Terms.
When the Company accepts an application, it sets up the applicant’s account and notifies the applicant.
The Company may refuse an application, without disclosing its reasons, where the applicant has an improper purpose, intends to research a similar service, may violate these Terms, provided false or incomplete information, previously had a related agreement terminated, is or may be an Antisocial Force, or where the Company otherwise considers use inappropriate.
An Agreement is formed when the Company notifies the applicant that account setup is complete.
Customers must promptly notify the Company of changes to information provided in the application. The Company may request documents verifying the change.
Customers must manage Account Information responsibly and must not allow third parties to use, disclose, or receive it.
Customers are responsible to the Company for all activity performed through their Account Information as if performed by the customer.
Customers must promptly notify the Company and follow its instructions if Account Information is stolen, leaked, used by a third party, or at risk of such use.
Customers must pay the Service Fees for their selected Plan by the deadline and method specified by the Company. Customers bear costs necessary for payment.
Prices shown are exclusive of applicable taxes. Applicable consumption tax and other taxes are added separately based on billing information and shown at application or checkout.
Except where the Company is responsible for a Service failure or these Terms specifically provide otherwise, paid Service Fees are not refundable.
Late payment incurs damages at an annual rate of 14.6%.
Customers may use the Service under these Terms after payment of Service Fees is complete, or, for the Free Plan, when the Agreement is formed.
Customers are responsible for preparing and maintaining the required devices, software, network, and security environment, including protection against viruses, unauthorized access, and leaks.
The Company may outsource all or part of the work it considers necessary to provide the Service, while remaining responsible for the Service.
The Company is responsible for Contractors’ performance to the same extent as if it performed the work itself.
Customers must not violate these Terms or law; commit fraud, threats, defamation, or interference; infringe rights or privacy; engage in crime, harassment, discrimination, or other nuisance; send malware; overload or attack the Service; reverse engineer or analyze the Service; alter accessible information; interfere with operation; support Antisocial Forces; attempt any such conduct; or otherwise use the Service improperly.
If conduct falls within the preceding paragraph, the Company may, without prior notice, restrict use, delete the account, or take other measures. The Company is not liable for resulting damage.
The Company may audit Service usage to the extent necessary to check for prohibited conduct, and customers consent to this in advance.
The Company may suspend all or part of the Service without prior notice when maintenance, a system failure, disaster, power outage, epidemic, or other circumstance makes suspension necessary.
Unless notice was given in advance, the Company will notify customers without delay. The Company is not liable for damage caused by suspension.
The Company may discontinue all or part of the Service after prior notice. If it determines that resumption is not technically or operationally possible after a suspension, it may discontinue the Service without prior notice.
If the entire Service is discontinued, the Agreement ends. Any prepaid fees for the period after discontinuation will be refunded on a daily prorated basis, with amounts below one yen rounded down.
The Company is not liable for damage caused by discontinuation.
Each party must keep confidential all technical, business, and other business information learned through the Agreement, must not disclose it without prior written consent, and may use it only to perform the Agreement.
Information already held, public when disclosed, later becoming public without fault, lawfully obtained from an authorized third party, or independently developed is not Confidential Information.
Information may be disclosed as necessary to officers, employees, Contractors, attorneys, accountants, tax accountants, and other persons bound by legal confidentiality. Officers, employees, and Contractors must have equivalent obligations. Disclosures required by law must be notified without delay.
Confidential Information may be copied as necessary for performance and must be returned, destroyed, or erased at the end of the Agreement as directed by the other party.
We handle Personal Information obtained from customers in accordance with our Privacy Policy. Applying to use the Service constitutes consent to that handling.
Customers must obtain the consent of their officers and employees who use the Service to the handling described in our Privacy Policy.
Ownership and Intellectual Property Rights in the Company Website, the Service, and their software, databases, images, text, manuals, and other components belong to the Company or its licensors. Permission to use the Service does not transfer or license those rights.
Customers must not infringe or risk infringing those rights, including by disassembly, decompilation, or reverse engineering.
Customers retain copyright in design tokens, components, DESIGN.md files, and other content created using the Service (“Customer Content”). Customers grant the Company and its Contractors a royalty-free license to use Customer Content, including copying, storing, transmitting, displaying, and processing it, to the extent necessary to provide, operate, maintain, and improve the Service.
Customers must send notices to the Company through the prescribed contact form on the Company Website or another method specified by the Company.
The Company may send notices by email or another specified method. An email notice takes effect when sent to the email address provided by the customer.
The Company does not warrant that the Service is free of programming errors or other defects, solves business problems, improves performance, is fit for a particular purpose, commercially useful, complete, accurate, or continuous. Customers use it at their own responsibility.
The Company does not warrant that use complies with laws applicable to customers or their contracts with third parties. Customers must investigate this themselves.
The Company has no duty to manage or preserve information supplied by customers or output through the Service. Customers are responsible for managing and preserving it.
The Company makes no warranty regarding External Services and is not liable for issues caused by them.
Only where damage is caused by the Company’s willful misconduct or gross negligence, the Company will compensate direct and ordinary actual damage. The cap is the total Service Fees actually received from the customer during the preceding year. Consumer contracts are handled as required by law.
The Company may suspend the Service or terminate the Agreement without notice or demand if the customer fails to pay, breaches the Agreement, provided false or materially incomplete information, engages in prohibited conduct, becomes insolvent, receives regulatory or execution measures, enters insolvency proceedings, resolves dissolution or a business transfer, suffers a material credit change, or if the Company otherwise considers continuation difficult.
The Company is not liable for damage caused by suspension or termination. A terminated customer must compensate damage caused to the Company and immediately pay all obligations after losing the benefit of time.
Each party represents and warrants that it and its officers are not Antisocial Forces, have no relationship in which Antisocial Forces control or materially participate in management, do not use or support Antisocial Forces, and have no socially objectionable relationship with them.
Neither party will make violent or excessive demands, use threats or violence, spread rumors, use deception or force to interfere with business or damage credit, or engage in equivalent conduct.
If the other party breaches these commitments, the Agreement may be terminated without demand. The breaching party must compensate the other party and may not claim its own termination damages.
The Free Plan runs from formation until a cancellation request reaches the Company. The monthly Pro Plan runs for one month and the annual Pro Plan for one year. Pro Plans automatically renew for the same term and conditions unless either party acts before expiration.
Customers may request cancellation through the prescribed process at any time. Free ends when the request reaches the Company; Pro ends at the end of the current term.
Customers may apply to change Plans at any time through the prescribed process.
A Free-to-paid change and a monthly-to-annual Pro change take effect when the Company notifies the customer that the change is complete; the prior Agreement ends and the new Agreement begins then. Other changes take effect when the prior Plan’s term ends.
For a monthly-to-annual Pro change, the amount due is the annual Pro fee less the daily prorated monthly fee for the remaining period from the day after the application through the monthly term’s end. The change is effective immediately and the difference is charged immediately using the method shown at checkout.
Customers must compensate the Company for damage caused by their fault in breach of these Terms or in connection with using the Service.
If a dispute with a third party arises through the customer’s fault, the customer must promptly report it and resolve it at its own cost. The customer must compensate the Company for resulting damage, including attorneys’ fees.
The Company may change the Service without customer consent.
When necessary due to legal changes, social conditions, Service changes, or other circumstances, the Company may change these Terms. It will give advance notice of the change, revised content, and effective date through the Service, the Company Website, or another prescribed method.
Continued use after the effective date constitutes agreement to the revised Terms.
Customers may not assign or provide as security their position, rights, or obligations under the Agreement without the Company’s prior written consent.
When transferring the Service business to a third party, the Company may transfer its position, rights, and obligations under the Agreement, and customers consent in advance.
These Terms constitute the entire agreement between the customer and the Company regarding their subject matter and supersede all prior oral or written agreements and understandings.
If any provision or part of these Terms is invalid or unenforceable under law, the remaining provisions remain in full force and effect.
These Terms are governed by and construed under the laws of Japan. The Tokyo District Court has exclusive jurisdiction as the court of first instance for all disputes relating to these Terms or the Service.
Customers and the Company will consult in good faith to resolve matters not provided for in these Terms and any questions regarding their interpretation.
