1. Introduction
Please read these Terms of Use (the "Terms") carefully before using the iOS app "ComicDeck" (Japanese name コミックデッキ, the "App") provided by T.K Apps ("we"). By using the App, you agree to these Terms.
2. Purpose of the App
The App is a manga tracking app that lets you add the manga you've read, own, or want to read to a shelf, and record and organize your reading status, volumes read, volumes owned, ratings, notes, tags, and more.
The App does not sell manga or provide manga for reading. Manga information is retrieved from external book information services, and we do not guarantee its accuracy. The App is not affiliated with any publisher or author.
3. Your Responsibility
You use the App at your own risk. You are responsible for entering, managing, and sharing your reading records, notes, photos, tags, and exported data.
4. Prohibited Conduct
You must not:
- Violate any law or public order and morals
- Infringe the rights, privacy, publicity rights, or copyrights of others
- Interfere with the operation of the App or the external services it uses (for example, automated mass searches)
- Analyze, modify, or reverse engineer the App
- Engage in any other conduct we consider inappropriate
5. Data and Backups
Your shelf data and reading records are stored on your device. Data may be lost due to device failure or loss, deleting the App, OS problems, and similar causes.
Please use the backup feature as needed and keep your data safe at your own responsibility.
6. Manga Information and External Services
Manga information and cover images are retrieved from external services such as the Rakuten Books API. Changes, outages, failures, or usage limits of those services may make search or image display unavailable.
Rights to manga titles, cover images, and trademarks belong to their respective owners. Please respect those rights when you share tier list or year-in-review images.
Purchases and transactions made through store links in the App are between you and each service, under that service's terms.
7. Photos
You must have the necessary rights or permission for any photos you register as cover images. Registering or sharing photos that infringe the rights of others is prohibited. Registered photos are stored only on your device.
8. Advertising
The App displays ads. If a paid plan is offered, ads are hidden while the paid plan is active.
9. In-App Purchases
The App may offer a paid plan (Premium), which removes ads and enables CSV export and other features.
- Purchases are made through the App Store (Apple).
- Prices, free trials, and renewal terms follow what is shown on the App Store. Subscriptions renew automatically unless canceled at least 24 hours before the end of the period, and can be managed or canceled in your App Store settings.
- For refunds, please contact Apple Support.
- We may change or end the benefits of the paid plan.
10. Changes, Suspension, and Termination
We may change the App, add or remove features, or suspend or end the App without prior notice.
11. Disclaimer
Except in cases of our intent or gross negligence, we are not liable for data loss, device problems, or damages to you or third parties arising from use of the App.
We make no warranty as to the accuracy, completeness, or fitness for a particular purpose of the manga information shown in the App (such as volume counts and release dates) or the content you record.
12. Privacy
For how the App handles information, please see our Privacy Policy.
13. Changes to These Terms
We may change these Terms as needed. Changes take effect when posted on this page. By continuing to use the App after a change, you agree to the updated Terms.
14. Governing Law and Jurisdiction
These Terms are governed by the laws of Japan. The courts of Japan have exclusive jurisdiction over any dispute relating to these Terms.
