Terms of Service

Effective date: July 15, 2026 Last updated: July 15, 2026

These Terms of Service (“Terms”) are a binding agreement between you and TechMO LLC (“refiner-ai”, “we”, “us”, or “our”) and govern your use of the refiner-ai macOS application, the refiner-ai.app website, and related account and sync services (together, the “Service”).

By creating an account, installing, or using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

1. Eligibility

You must be at least 18 years old to use the Service. If you use the Service on behalf of an organization, you represent that you are authorized to bind that organization to these Terms.

2. The Service

refiner-ai is a macOS utility that, when you select text in another application and trigger it, sends that text off your device to be rewritten, translated, or summarized by third-party artificial intelligence providers, and returns the result — including by replacing the selected text in place. The Service also lets you save “Context”, “Profiles”, and “Cards” and sync them across your devices. Features, limits, and supported platforms may change over time.

3. Accounts

You are responsible for the accuracy of your account information, for keeping your credentials secure, and for all activity under your account. Notify us promptly at support-team@techmo.jp of any unauthorized use. We may suspend or terminate accounts as described in Section 12.

4. License to use the App

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control, for your personal or internal business use. You may not copy, modify, reverse engineer, decompile, resell, sublicense, or create derivative works from the Service, except to the extent this restriction is prohibited by law.

5. Your content

a. Ownership. As between you and us, you retain all rights in the text you submit (“Input Content”) and in the results returned to you (“Output Content”). We do not claim ownership of them.

b. License to operate the Service. You grant us a limited license to process, transmit, store, and display your Input Content, Output Content, Context, Profiles, and Cards solely to provide and maintain the Service, including sending Input Content to our AI providers as described in the Privacy Policy.

c. Your responsibility for content. You represent that you have the rights and any necessary permissions to submit your Input Content, and that doing so — and using the Output Content — does not violate any law or third-party right (including privacy, confidentiality, and intellectual property rights). Do not submit content you are not authorized to share.

6. Artificial intelligence — accuracy and your responsibility

Please read this section carefully.

The Service uses AI to generate Output Content, and by design it can replace your selected text in place. AI output may be inaccurate, incomplete, outdated, biased, or inappropriate for your purpose. Translations and summaries may change or omit meaning; a rewrite may alter the substance of what you wrote.

• You are solely responsible for reviewing Output Content before you rely on, send, publish, or otherwise use it.
• The Service is not a substitute for professional advice (legal, financial, medical, or otherwise) and must not be relied on as such.
• We do not warrant that Output Content is accurate, fit for any purpose, or free of errors, and we are not responsible for actions you take based on it.

Because the App can overwrite your original text, we recommend keeping your own copies of important content.

7. Acceptable use

You agree not to use the Service to:

• violate any law or the rights of others;
• submit content you lack the right to submit, or that is unlawful, infringing, or malicious;
• attempt to disrupt, overload, reverse engineer, or gain unauthorized access to the Service or its providers;
• circumvent usage limits, credits, or security features;
• attempt to extract, reverse-engineer, or reconstruct the Service’s system prompts, model instructions, or other underlying prompts or configuration, including by prompt injection or similar techniques;
• use the Service to build or train a competing product; or
• use the Service in a way that violates our AI providers’ acceptable-use policies.

8. Subscriptions, credits, and billing

a. Plans and credits. The Service offers a free tier and paid plans, which include monthly usage credits and card limits. Current features and prices are shown at refiner-ai.app and in the App. As of the effective date the paid plans are Basic, Double, and Heavy, billed monthly or annually (annual billing is discounted); credits are consumed as you use refine and examine features.

b. Billing and processor. Paid plans are billed through a third-party payment processor. By subscribing, you provide your payment details to that processor and authorize the charges described below.

c. Auto-renewal. Subscriptions automatically renew at the end of each billing period (monthly or annual) at the then-current price unless you cancel before the renewal date. By subscribing, you authorize us (through our payment processor) to charge your payment method on a recurring basis until you cancel.

d. Cancellation. You may cancel at any time through your account billing settings (the payment processor’s customer portal, opened from the dashboard). Cancellation takes effect at the end of the current billing period, and you keep access until then.

e. Refunds. Except where required by law, payments are non-refundable and there are no refunds or credits for partial periods. We may grant discretionary exceptions on a case-by-case basis where we determine one is warranted (for example, following a support investigation). Consumers in Japan, the EU, and certain other regions may have non-waivable statutory rights that this section does not limit.

f. Price changes. We may change prices or plan features. We will give you advance notice of price increases affecting your subscription, and the new price will apply from your next renewal unless you cancel.

g. Taxes. Prices exclude applicable taxes such as Japanese consumption tax, which will be added where applicable. You are responsible for any taxes not collected by us.

h. Free tier. The free tier is a standing free plan with limited one-time credits, not a timed trial; it does not automatically convert to a paid subscription. Any promotional trials we may offer will be subject to additional terms disclosed at the time.

9. Third-party services

The Service relies on third parties (including our AI providers, hosting, and payment processor). We are not responsible for third-party services, and your use of them may be subject to their terms.

10. Our intellectual property

The Service, including the App, website, software, and the refiner-ai name and logo, is owned by us or our licensors and protected by intellectual property laws. These Terms grant you no rights in our trademarks or branding except as needed to use the Service.

11. Feedback

If you send us suggestions or feedback, you grant us a non-exclusive, perpetual, royalty-free license to use it without obligation to you.

12. Suspension and termination

You may stop using the Service and delete your account at any time. We may suspend or terminate your access if you breach these Terms, if required by law, or to protect the Service or other users. On termination, your license ends; sections that by their nature should survive (including Sections 5–6, 8, 10, and 13–16) survive.

13. Disclaimers

To the maximum extent permitted by law, the Service is provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and any warranty regarding accuracy, availability, or AI output. Some jurisdictions do not allow certain disclaimers, so parts of this section may not apply to you.

14. Limitation of liability

To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits, data, or goodwill, arising from or related to the Service. Our total liability for any claim will not exceed the greater of JPY 10,000 or the amount you paid us for the Service in the 3 months before the event giving rise to the claim. Nothing in these Terms excludes liability that cannot be excluded by law, including certain rights of consumers.

15. Indemnification

You agree to indemnify and hold us harmless from claims and costs arising out of your Input Content, your use of the Service, or your breach of these Terms, to the extent permitted by law.

16. Governing law and disputes

These Terms are governed by the laws of Japan, without regard to conflict-of-law rules. The Tokyo District Court will have exclusive jurisdiction of the first instance over disputes, except where mandatory consumer-protection law gives you the right to bring proceedings elsewhere.

17. Changes to these Terms

We may update these Terms from time to time. If changes are material, we will notify you by email and/or in-app notice and update the “Last updated” date. Your continued use after changes take effect means you accept the updated Terms; where required by law, we will seek your consent.
