Welcome to KrKrCat (the “App”). We take your privacy seriously. This Privacy Policy explains how we collect, use, store, and protect your information when you use the App to import, manage, and play visual novels.
Everything stays on your device
The visual novels, saves, and settings you add are stored only on your device.
Your files are never uploaded
None of your files are uploaded to our servers or any third party’s.
No tracking, no profiling
Your data is never used for ad tracking or user profiling.
1Information We Collect
1.1 Information we process
The App follows the principle of data minimisation and processes only what its features require:
Local app data: the list of visual novels you import and their metadata (such as name, cover, last opened time, and total reading time), saves, and app settings (such as appearance, accent colour, app icon, floating ball, and sort order). This data is stored only in the App’s sandbox on your device.
LAN Upload (optional): when you turn on LAN Upload, devices on the same Wi-Fi network can upload files to this device through a web browser. The transfer happens directly between your own devices on your local network and never passes through our servers or any third party’s. Files are saved straight into the App’s sandbox.
Diagnostic logs: the App may keep a small log on your device to diagnose problems with importing, extracting, or playing files. Logs stay on your device and are never uploaded automatically.
Diagnostics in feedback emails: when you contact us through “Send Feedback Email”, the email template is pre-filled with the App version, device model, and system version to help us investigate. You review the email in your own mail app and decide whether to send it; the App does not collect or upload this information by itself.
1.2 Information we do not collect
Your contacts, calendars, messages, or other personal communications;
Precise location (such as GPS);
Information that directly identifies you (such as your real name or ID number);
The advertising identifier (IDFA) or any cross-app tracking data;
Your Apple Account password, card numbers, or other financial information (handled solely by Apple).
2How We Use Information
The information above is used only to:
Provide the App’s core features, such as importing, managing, and playing visual novels and keeping your progress and settings;
Receive files from your other devices through LAN Upload, when you turn it on;
Diagnose problems you report and improve the App’s stability and compatibility;
Meet legal or regulatory requirements, where applicable.
3Storage and Security
3.1 Local storage
Visual novel files, saves, settings, and state are all stored in the App’s sandbox on your device. Apart from mechanisms provided by iOS itself (such as device backups), we never upload this content to any server. You can delete a visual novel in the App at any time, or remove all local data by deleting the App. Please export any saves you want to keep before deleting it.
3.2 Permissions
The App asks for the following permissions only when you use the related feature:
Local Network (LAN Upload): used only while LAN Upload is on, to receive files from your other devices on the same Wi-Fi network. It is not used for any other network access.
Photos (add only): used only when you choose to save a screenshot, to add it to your photo library. The App requests add-only access and cannot read anything in your library.
3.3 Security measures
App data is isolated by the iOS sandbox;
Data is accessed and managed only through system interfaces provided by Apple;
The App includes tamper detection used solely to verify in-app purchase entitlements. It runs entirely on your device, collects and uploads nothing, and does not affect normal App Store users.
4Third-Party Services
4.1 Apple services
App Store: used to distribute the App and its updates. Data related to downloads and updates is handled by Apple.
In-App Purchase (StoreKit): if you buy a paid feature (such as PRO), payment is handled entirely by Apple. We never see, collect, or store your payment details; the App only checks your purchase status on device through Apple’s interfaces.
4.2 Open-source components
The App uses a number of open-source components to play visual novels compatibly and efficiently. These components process data only on your device and upload nothing. Their licenses are listed in the App under Settings › About › Open Source Licenses.
4.3 External links
Opening this page, joining the QQ community, or sending a feedback email from the App takes you to external apps or services such as your browser, QQ, or your mail app. Their handling of data is governed by their own privacy policies.
5Your Rights
Access: you can view your imported visual novels, saves, and settings in the App;
Deletion: you can delete any visual novel at any time, or remove all local data by deleting the App;
Permissions: you can turn Local Network, Photos, and other permissions on or off at any time in iOS Settings;
Withdrawal: once you turn off a permission or feature, the App stops further processing of the related data, unless the law requires otherwise.
6Minors
The App is intended for general users who can read and operate a device. It is not designed for children and does not knowingly collect personally identifiable information from children under 13.
If you are a minor, please read this policy with your guardian and use the App only with their consent. If you are a guardian and believe the App has collected a child’s information without your consent, please contact us using the details in Section 8 and we will look into it promptly.
7Changes to This Policy
We may update this Privacy Policy as the App’s features or applicable laws change. For material changes, we will ask for your agreement again within the App or give notice prominently, for example in the release notes. Please check this page from time to time for the latest version.
By continuing to use the App after an update, you confirm that you have read, understood, and accepted the updated policy.
