Terms of Use (English)

Effective: October 19, 2026

These terms govern your use of Rankpin ("the app"), operated by Rintaro Sakino ("we"). If the Japanese and English versions differ, the Japanese version prevails.

1. License

Apple's Licensed Application End User License Agreement applies. If these terms conflict with it, the Apple agreement prevails.

2. Price and refunds

The app is a one-time purchase with no in-app purchases or subscriptions. Apple handles purchases and payments, and we do not receive any purchase information. Refunds follow Apple's process: request one at reportaproblem.apple.com. Apple decides whether to issue a refund, and we cannot issue refunds ourselves.

3. About the information shown

Ranks, rating counts, seller names, and release dates come from Apple's public chart data (such as the iTunes Store RSS feeds) and the iTunes Search API. We do not guarantee that this information is accurate, complete, or current. Only the top 100 of each chart can be shown, and ranks may briefly differ from the App Store because of Apple's update timing. "Indie Apps (Estimated)" is estimated from seller names and may be wrong. The numbers are one input for choosing a category and do not guarantee any rank or sales; your app's category must match what the app does (App Review Guideline 2.3.5). Checks and notifications while the app is closed run when iOS schedules them and may be delayed or skipped. If Apple changes or stops providing this data, some or all features may stop working; we will post the status on the support page and work on an update. App names and icons belong to their owners and are shown only to identify apps in the charts. Rankpin is not affiliated with or endorsed by Apple Inc.

4. Prohibited conduct

Do not break the law, use the app to manipulate App Store charts, ratings, or reviews, modify or reverse-engineer the app, resell or redistribute the app or its assets, sell or distribute information shown in the app in bulk, or harm us or others.

5. Disclaimer

We do not guarantee that the app is free of bugs, works on every device, or fits your purpose. Your apps and rank history are stored only on your device, and we cannot restore lost data. We may change or discontinue the app. Except for our intentional misconduct or gross negligence, our liability for damages arising from your use of the app is limited to the amount you paid for the app.

6. Changes

We may change these terms. Changes take effect when posted on this page.

7. Governing law

These terms are governed by the laws of Japan. The Tokyo District Court has exclusive jurisdiction in the first instance.
