C Starter Privacy Policy
1. Scope and local data
C Starter is provided by Dozen Network Technology Co., Ltd. This policy describes version 0.1.0. Project names and IDs, source files, preset input, course drafts and progress, preferences, workspace permissions/bookmarks and a purchase-access snapshot are stored locally. The app does not upload projects, source code, input, output or learning progress to developer servers. No app account, advertising, cross-app tracking, remote compilation or app-provided cloud backup is included.
2. Compilation, files and search
The compiler and C libraries are bundled with the app and run locally in WebKit/WebAssembly. Bundled resources use a local custom URL scheme; this does not expose a network server. Program-created files are temporary within each run. Search extracts bundled content locally and uses available system language models to create locally cached vectors; queries and vectors are not uploaded. Keyword search remains available when a model is unavailable.
3. Activity requests and service logs
The home-screen activity feature requests content from content.ministep.site or content.ministep.app with app language, App Store storefront, platform, version and build. Images and links may contact their indicated hosts. Requests may create server logs containing IP address, time, URL and parameters, User-Agent, response status and processing duration. We use these logs for content delivery, service analysis, troubleshooting, security and applicable legal obligations, not advertising or cross-app tracking.
4. Apple purchases
StoreKit retrieves products and verifies one-time IDE Pro transactions, restores purchases and updates refunded or revoked access. Entitlement status is cached on the device. Apple processes payments and its services under Apple’s policies and your settings. The app does not receive payment-card or bank-account details.
5. Support and web access
If you email support, we receive the address, message and attachments you choose to send and use them to respond and resolve your request. Remove unrelated personal information and secrets. Opening support, privacy or other web pages also creates ordinary server access logs. Copy and paste are initiated by you; editor input is not uploaded.
6. Retention and safeguards
Local projects remain until removed; Recently Deleted permits recovery while the files remain available. Clearing app data or deleting the iPhone/iPad app may remove projects and progress; Mac folders outside the app container may remain. File providers operate under their own settings. Server logs and support messages are retained only as needed for the service, support, security and legal purposes described here, then deleted or anonymized unless further retention is required. Online services use access controls and encrypted transport.
7. Choices and requests
No login is required. You can manage local projects, workspace locations and app data and choose whether to open external links or contact support. For access, correction, deletion or other applicable requests about server records or support messages, email ministep@dozen.network. We may need information to locate and verify your request; legally required records may need to be retained.
8. Changes and contact
We will update this policy and relevant App Store information before introducing materially different data processing. Contact ministep@dozen.network, Dozen Network Technology Co., Ltd., with privacy questions. The app is for general programming learning and does not request a child’s name or contact details.
