1. Introduction
T.K Apps ("we") respects your privacy and is committed to protecting your personal information when you use the iOS app "ComicDeck" (Japanese name コミックデッキ, the "App"). This policy explains how the App handles information.
2. Information the App Stores
The App stores the following information that you enter or select.
| Type | Details |
|---|---|
| Manga information | Title, author, publisher, genre, ISBN, release date, cover image URL, description, and per-volume information, either retrieved from a book information service or entered by you |
| Reading records | Status (want to read, reading, finished, dropped), volumes read and when, volumes owned, rating, date added, start date, finish date, reviews, notes, series, tags, and tier lists |
| Photos | Photos you register as cover images, and images you take or choose to capture text into notes |
| App settings | Appearance, theme color, rating style, displayed fields, search history, and similar settings |
| Exported data | Shelf data you export as a backup (JSON) or in other formats |
3. Where Information Is Stored
Your shelf data, reading records, and photos are stored on your device. The App does not send or store your reading records or photos on any server of our own, and no account is required.
To show the home screen widget, the App saves the titles, cover images, and counts of the manga you're reading to a shared area on the same device (App Group).
If you use OS backup, sharing, or export features, you are responsible for how that data is handled at its destination.
4. Retrieving Manga Information
To search for manga and retrieve manga information and cover images, the App uses the Rakuten Books Total Search API and Rakuten Books Book Search API provided by Rakuten Group, Inc. When you search, the search terms you enter (title, author, ISBN) are sent to Rakuten. Retrieved images are cached on your device for display.
5. External Links
Store links in the App (Amazon, Rakuten Books) open the store's search results or product page, and "Search the web" opens Google Search. Information at those destinations is handled under each service's own policy.
6. Camera, Photos, and Photo Library
The App may ask for camera access to scan the barcode (ISBN) on the back of a manga volume. The camera feed is used only to read the barcode and is never saved or sent.
The App may also ask for access to the camera or photo library to register cover photos and to capture text into notes. Text recognition runs on your device (Live Text), and images are never sent outside your device. Registered photos are stored only on your device.
7. Advertising and Tracking
The App displays ads served by Google AdMob. The ad provider may collect device information, the advertising identifier, and usage information to show ads, prevent fraud, and measure ad performance.
On iOS, the App asks for permission through App Tracking Transparency (ATT). If you decline, all features of the App remain available (ads will not be personalized).
8. In-App Purchases
The App may offer a paid plan (Premium) that removes ads and enables CSV export. In-app purchases are processed through Apple's StoreKit / App Store. We never receive or store payment information such as credit card numbers.
9. Sharing with Third Parties
We do not share your information with third parties without your consent, except as required by law, as necessary to protect users or prevent misuse, or with the third-party services described in this policy.
10. Deleting Data
You can delete manga, volumes, reading records, photos, notes, tags, series, tier lists, search history, and more within the App. If you uninstall the App, the data stored on your device is deleted according to the OS behavior.
Please manage and delete any backup files you have exported yourself.
11. Changes to This Policy
We may update this policy as needed. Any changes will be posted on this page with an updated date.
