Privacy Policy

Last updated: August 2026

1. Zero Data Collection

OneToolBox is designed from the ground up to respect user privacy. We do not collect, store, transmit, or monetize your personal files, text inputs, images, or outputs. All tool executions happen 100% locally within your client browser.

2. Local Storage

We use browser `localStorage` solely to save your UI preferences (such as light/dark mode selection and recently viewed tools). This data remains exclusively on your local device and is never transmitted to us.

3. Cloudflare Pages Hosting

Our website assets are hosted on Cloudflare Pages. Cloudflare may process basic server request logs (IP addresses, user agents) strictly for security and DDoS protection in accordance with their privacy policy.

Technical Privacy Architecture

Traditional online utilities upload files to backend cloud servers for processing. OneToolBox operates on a zero-server upload architecture. All operations—including image compression, WebP conversion, JSON parsing, YAML validation, cryptographic hashing, and UUID generation—execute locally inside your client browser using JavaScript, Web Cryptography API, and HTML5 Canvas.

Because your files, images, source code, and API keys are never uploaded to any remote server, your sensitive data remains completely confidential and under your direct control at all times.

Cookies and Local Storage

We use browser `localStorage` solely to remember your user interface preferences, such as light/dark theme selection. We do not place third-party tracking cookies or sell user session data to advertising networks.
