Your selected APK stays in the browser.

The file-checking tool reads the selected file with browser APIs and calculates SHA-256 locally. It does not include an upload endpoint and does not intentionally send file contents, filenames or resulting digests to this site’s server or analytics. Closing the tab removes the tool’s in-memory working state. Your original file remains on your device.

The calculation needs memory and JavaScript. Browser extensions, your device and third-party software are outside this tool’s control.

The site is delivered through Cloudflare Pages. Hosting infrastructure may process request metadata such as network address, requested path, time and browser information for delivery and security.

Umami page analytics is enabled only when the site’s valid website ID and script URL are configured at build time. The configured service may receive page address, referrer and browser/device information according to its own service settings. The file-comparison tool does not attach selected-file details to page analytics. We do not describe analytics ingestion as verified merely because a script loads.

APK downloads, the supplied YouTube channel, source citations and the sponsored partner platform can leave this domain. The partner action opens LUCKX and is separate from this editorial site; any registration, account, payment or data entry is governed by that provider. This site does not request account passwords, OTPs or KYC documents.
