Your API definition stays on your device
The checker reads your selected file in the browser and processes it in a Web Worker. It does not send the contents, filenames, findings, or repaired definitions to a server.
No content collection
Usage measurement is disabled in this release. No visit, diagnosis, preview, or download events are sent. There are no third-party scripts, tracking pixels, error-reporting SDKs, accounts, or persistent browser storage. Reloading or clearing the checker discards its in-memory copy.
What uses the network?
Your browser downloads this website’s static pages and assets from the hosting provider. The provider may process ordinary request metadata such as your IP address. Opening an official reference link visits that external website. External references in your API file are never requested.
Downloads are your choice
A repaired file or diagnostic report is generated only in your browser. Reports can contain source paths and security configuration from your file. Review them before sharing with anyone.
Limits
This tool cannot protect a compromised device or browser extension. Do not use sensitive definitions on a device you do not trust.
