Privacy Policy

Effective Date: November 2026

1. Zero File & Input Data Collection

We do not store, view, or transmit any files, images, PDFs, JSON code, or text that you process using Modern Web Toolbox. All processing occurs locally within your web browser's JavaScript and WebAssembly environment.

2. Local Storage Usage

We use your browser's standard localStorage exclusively to save your tool preferences (such as light/dark mode, recent tools, and favorite tool IDs). We never store user document contents or sensitive payloads in local storage.

3. Analytics & Advertising

We may use privacy-preserving, cookieless analytics (such as Cloudflare Web Analytics) to understand aggregate page views and popular tools. If advertising is enabled in the future, standard consent mechanisms (Google Consent Mode & certified CMPs) will be implemented in accordance with GDPR and applicable privacy regulations.
