Article 1 (Scope)

These Terms of Use (the "Terms") set out the conditions for using LinkSentinel (the "App"). By downloading or using the App, you are deemed to have agreed to these Terms.

Article 2 (The service)

As an extension for Apple Mail, the App provides the following features:

Checking the links in your mail (including detecting mismatches between the displayed link and its real destination)
Detecting and warning about sender impersonation and phishing mail
Checking sender authentication (SPF, DKIM, DMARC)
Domain management with Trusted Senders (Whitelist), Blocked Senders (Blacklist), Watch Domains (Untrusted Domains) and more

Article 3 (Conditions of use)

To use the App, you must meet the following conditions:

You use an Apple computer running macOS 15 or later
The Apple Mail app is installed
You have an active subscription (including the free trial) as set out in Article 4
You agree to these Terms

Article 4 (Subscription and fees)

The App is offered as an auto-renewing subscription (a monthly or yearly plan; the "Subscription"). It is not offered as a one-time purchase.
The Subscription fee is the amount shown in the App Store and in the App's subscription window. Purchases and payments are made through Apple's App Store, and fees are charged to your Apple ID.
Users subscribing for the first time can use a 14-day free trial (once per Apple ID, subject to Apple's conditions). Unless you cancel at least 24 hours before the free trial ends, the Subscription to the plan you chose starts when the trial ends and you will be charged. If you start a paid Subscription during the free trial, the remainder of the free trial is forfeited.
Unless cancelled at least 24 hours before the end of each period, the Subscription renews automatically for the same period, and the fee in effect at the time of renewal is charged to your Apple ID within 24 hours before the renewal. Price changes are subject to Apple's notification and consent procedures.
You can review, change or cancel the Subscription in your App Store account settings (or from "Manage Subscription…" in the App's menu). If you cancel, you can continue to use the App until the end of the period already paid for.
A switch between the monthly and yearly plans takes effect on the next renewal date, after the current period ends. The remainder of the current period is not refunded.
Refunds follow Apple's policy. The developer does not process refunds.
While the Subscription is not active (before the free trial starts, after it expires, after it is revoked by a refund and so on), the App does not analyze mail, and features such as settings and the Email Analysis History are unavailable.
The Subscription supports Family Sharing. Use through Family Sharing is subject to Apple's conditions.
The developer may change the Subscription fee or its contents. Price changes will be communicated to you through the procedures Apple specifies.

Article 5 (Prohibited conduct)

You must not:

Decompile, reverse engineer or disassemble the App
Modify the App or create derivative works
Redistribute, sell or rent the App
Use the App for unlawful purposes
Attempt to circumvent or disable the App's security features

Article 6 (Disclaimer)

The App is provided "as is". Please note the following:

The App does not guarantee that it will detect every phishing message or malicious link. Because results are produced automatically from several signals, threats can be missed or misjudged
Labels such as "Links Verified" do not guarantee that a message or link is safe. The final decision to open a message or link is yours
The App should be used as one part of your security measures, and should not be relied upon as your only defense
The developer's liability for damage arising from the use of, or inability to use, the App is governed by applicable law. This clause does not limit liability for the developer's willful misconduct or gross negligence

Article 7 (Intellectual property)

All intellectual property rights in the App and its content belong to the developer. You are granted a non-exclusive license to use the App in accordance with these Terms.

Article 8 (Changes to and termination of the service)

The developer reserves the right to change, add or remove features of the App without prior notice. The developer also reserves the right to discontinue the App for any reason.

Article 9 (Changes to these Terms)

The developer may change these Terms as needed. The revised Terms take effect when they are posted in the App or on the website. If you continue to use the App after a change, you are deemed to have agreed to the revised Terms.

Article 10 (Governing law and jurisdiction)

These Terms are governed by and construed in accordance with the laws of Japan. The Tokyo District Court has exclusive jurisdiction as the court of first instance for any dispute relating to these Terms.

Article 11 (Personal information)

The App does not collect personal information. All mail analysis takes place on your device, and neither mail content nor analysis results are sent to the developer. Purchases and payments for the Subscription are handled by Apple's App Store, and the developer does not obtain your name, email address or payment method. See the Privacy Policy for details.
