lilC (“we”, “the app”) is a local C programming environment for iPhone, with a matching copy in the web browser. You write C in an editor and run it with PicoC, a small interpreter. This page is the public copy of the policy also summarized in Settings.
lilC does not require an account and does not collect your name, email, contacts, location, photos, or advertising identifiers. We do not use analytics, crash reporters, or advertising SDKs. These pages do not set cookies or load third-party scripts.
On iPhone, C source files you create are stored in the app’s Documents folder. Theme preference (Light or Dark) is stored in UserDefaults. In the browser copy, files and theme stay in this browser (IndexedDB / localStorage). We do not receive those files.
Local files are used only to let you edit, run, and share C programs. Theme preference is used only to style the app.
We do not sell or rent personal data. This version of lilC runs C on-device with PicoC. It does not send your code to a cloud AI. A future version may add an optional agent; that would require a later update, an in-app consent switch, and an updated privacy policy.
lilC does not track you across apps or websites. We do not use the App Tracking Transparency prompt because we do not track.
lilC is a general-audience coding tool. It is not directed at children under 13. We do not knowingly collect personal information from children.
You can delete an individual file from Home → Delete. You can erase all local files from Settings. Uninstalling lilC removes its local data from this device.
Programs run in a constrained interpreter. system() is disabled. Do not paste secrets you would not keep on your phone.
C lessons stay free. The iPhone app may offer a one-time (non-subscription) unlock for an offline Linux study course. Apple processes that purchase. This version of lilC does not sell a subscription.
The project is at github.com/garrettmichae1/lilc.
If this policy changes, we will update the date above and the in-app copy.
