Terms of Service

Last updated: July 12, 2026

These Terms of Service (“Terms”) govern your use of the macOS applications, the website at microai.jp, and the related online services (together, the “Service”) provided by microAI (“microAI”, “we”, “us”). By downloading, installing, or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. The Service

microAI publishes small macOS utilities and, for some of them, optional online features such as a cloud account, settings sync, cloud sharing, and access to third-party AI models. Some features are free, some require a paid license, and some require an active subscription.

2. Accounts

A cloud account is optional and is only needed for online features (for example, syncing settings across Macs). You may sign in by email (magic link), Google, or Apple. You are responsible for keeping access to your email and sign-in methods secure, and for activity that occurs under your account. You may delete your account at any time (see the Privacy Policy for how deletion is handled).

3. Licenses, payments, and trials

Paid apps are sold as a one-time purchase (perpetual license) or as a subscription, as shown on each product page. Payments are processed by our payments provider, Polar; we do not receive or store your full card details. Where a free trial is offered, it converts to a locked state when it ends unless you purchase a license.

One-time purchase (perpetual): you may use the version you have for as long as you like. It includes app updates released within the update period stated at purchase; updates released after that period require a renewal to receive in-app.
Subscription: access and updates continue while the subscription is active. If it lapses or is cancelled, paid features stop working.
A license may be activated on a limited number of Macs. You can deactivate a Mac to free a slot. Prices are shown exclusive or inclusive of tax as indicated at checkout.

Refunds are handled according to the refund policy shown at purchase and applicable law. If you purchase through Setapp, the Setapp subscription terms also apply to that copy.

4. AI features

Some apps offer access to third-party AI models (such as Anthropic Claude or Google Gemini) routed through our servers, available to eligible paid members. When you use these features, the content you submit is sent to the relevant AI provider to generate a response. You are responsible for the content you submit and for complying with the AI providers’ usage policies. AI outputs may be inaccurate or unsuitable and must not be relied on without your own judgement.

To keep the Service sustainable, AI usage is subject to fair-use rate limits and quotas, and may be throttled or suspended if we detect abuse, sharing, or resale of access. We do not guarantee availability of any particular model or that usage limits will not change.

5. Acceptable use

You agree not to:

circumvent, disable, or interfere with licensing, usage limits, quotas, or security;
share, resell, or provide access to paid features or AI access to third parties;
use the Service to break the law or to infringe others’ rights;
reverse engineer the Service except to the extent permitted by law;
overload, probe, or disrupt our infrastructure.

6. Software license

Subject to these Terms and your payment where required, microAI grants you a personal, non-exclusive, non-transferable license to install and use the apps on Macs you own or control. The apps are licensed, not sold; microAI and its licensors retain all intellectual property rights.

7. Third-party services

The Service relies on third parties including Cloudflare (hosting and storage), Polar (payments and licensing), Resend (email), and AI providers for AI features. Your use of those features is also subject to those providers’ terms.

8. Disclaimers

The Service is provided “as is” and “as available” without warranties of any kind, to the maximum extent permitted by law. We do not warrant that the Service will be uninterrupted, error-free, or fit for a particular purpose.

9. Limitation of liability

To the maximum extent permitted by law, microAI will not be liable for any indirect, incidental, special, or consequential damages, or for loss of data, profits, or goodwill. Our total liability for any claim relating to the Service will not exceed the amount you paid for the relevant app or subscription in the twelve months before the claim. Nothing in these Terms limits liability that cannot be limited under applicable law.

10. Termination

You may stop using the Service at any time. We may suspend or terminate access if you breach these Terms or misuse the Service. Provisions that by their nature should survive termination (such as licenses granted to us, disclaimers, and limitations of liability) will survive.

11. Changes to these Terms

We may update these Terms from time to time. Material changes will be reflected by updating the date above and, where appropriate, by notice. Continued use after changes take effect means you accept the updated Terms.

12. Governing law and contact

These Terms are governed by the laws of Japan, without regard to conflict-of-laws rules. Questions about these Terms can be sent to support@microai.jp, or on X at @microaijp.
