Last Updated: October 2026

1. Core Privacy Principle

MiniToolDesk is architected with a strict Zero Server Storage policy. All data transformations, file processing, cryptographic operations, and code formatting occur locally in your web browser session using client-side JavaScript, WebAssembly, and native Web APIs.

2. Data We Do Not Collect

We never view, log, transmit, or store any of the following:

Your code snippets, JSON files, or database strings
Your uploaded images, SVGs, or design assets
Your private cryptographic keys, passwords, or tokens
Any clipboard data accessed during paste operations

3. Cookies and Local Storage

We use browser LocalStorage solely to remember your UI preferences (such as light/dark mode selection and your recent tool settings). This data remains strictly on your local device and is never synchronized to our servers.

4. Third-Party Services & Advertising

We may display third-party advertisements (such as Google AdSense) to keep this service free. Third-party vendors, including Google, use cookies to serve ads based on prior visits to this website. You may opt out of personalized advertising by visiting Google Ads Settings.
