Privacy-First Computing Guide

Why Privacy-First Matters

Most online tools require you to upload your data to a server for processing. When you format a JSON file, convert a PDF, or use an AI writing tool on a typical website, your data travels across the internet, gets processed on a remote server, and is often stored indefinitely. Zilita takes a fundamentally different approach: every tool processes data entirely within your browser, on your device, using client-side JavaScript and WebAssembly.

How It Works

When you use a Zilita tool, your browser downloads the application code (HTML, CSS, and JavaScript) just like any website. However, instead of sending your input data to a server for processing, the code runs locally on your device. Your file, text, or settings are processed using your device's CPU and memory. The result is displayed in the browser and never transmitted over the network.

For AI-powered tools like the Humanizer and CBC Lesson Planner, Zilita uses WebAssembly and WebGPU to run machine learning models directly in your browser. The models are downloaded once and cached locally. Your prompts, text, and personal information never leave your device.

Data Storage

Zilita does not operate servers that store user data. There are no databases, no user accounts, and no cloud storage. The only data persistence happens through your browser's localStorage API, which saves data on your device for tools like the Notes App and Task Planner. This data stays on your computer and can be cleared at any time through your browser settings. No one else can access it.

What This Means for You

• No data leaks — Since your data never leaves your device, there is no risk of a server breach exposing your information.
• No tracking — Zilita does not collect analytics about what you type, upload, or process in the tools.
• Works offline — Many tools continue to work even without an internet connection after the initial page load.
• No account needed — You can use every tool without signing up, logging in, or providing an email address.

Frequently Asked Questions

Does Zilita use cookies for tracking?

Zilita uses essential cookies for technical functionality and Google Analytics for anonymous usage statistics. No personal data from tool inputs is collected or tracked.

Can my employer or ISP see what I process?

Since processing happens locally, only the initial page load is visible as a network request. The data you input into tools is not transmitted, so network observers cannot see it.

Is the AI model downloaded to my device?

Yes. AI models are downloaded to your browser cache the first time you use an AI tool. They are stored locally and reused on subsequent visits without re-downloading.

How do I clear my local data?

Open your browser settings, find the Privacy & Security section, and clear site data or localStorage for the Zilita domain. This will remove all locally stored notes, tasks, and settings.
