This privacy policy applies to the HarmonyOS application KLayout (bundle name
com.yangy79.klayout, hereinafter "the App").
The App is a purely offline layout viewer and editor. It does not connect to the internet, requests no system permissions, and does not collect, upload, or share any of your personal information or file contents.
The App does not collect, read, or upload any of the following:
To provide its core function (layout viewing and editing), the App processes and stores the following data locally on your device. This data never leaves your device:
| Data | Purpose | Storage location |
|---|---|---|
| Layout files you open or save | Viewing, editing, storage | The location you choose in the system file picker |
App settings (window layout, recent files, layer properties .lyp, etc.) | Remembering your preferences | App private directory |
| Bundled technology libraries, DRC rules, sample macros | Providing default functionality | Extracted to the app private directory on first run |
You can permanently delete all of this local data at any time by uninstalling the App.
The App's manifest (module.json) declares no system permissions at all
(requestPermissions: []). Specifically:
ohos.permission.INTERNET) — the App has no
networking capability whatsoever and cannot transmit data.You can verify the permissions the App actually holds under "Settings → Apps → KLayout". Currently this is none.
Because the App does not access the network and collects no data, there is no data transmission or remote storage, and therefore no related risk of data leakage. The security of local data relies on the HarmonyOS application sandbox, together with your device's screen lock and encrypted storage. Please keep your device secure and enable screen locking.
Since the App collects, stores, and shares no personal information, there is no need for data access, correction, deletion, consent withdrawal, or account deletion procedures. You have full control over all data associated with the App (which consists solely of local files); uninstalling the App removes all settings and caches from its private directory.
The App collects no personal information and therefore performs no collection of information concerning minors. The App contains no advertising, paid content, or content unsuitable for minors, and is suitable for all users, including minors. If you are the guardian of a minor and have questions about its use, please contact us using the details below.
If this policy changes, we will update this page and revise the "Last updated" date accordingly. If a change materially affects your rights, we will notify you prominently within the App. Please review this page periodically for the latest version.
