How does ZTools handle privacy? Do my files and data get uploaded to any server?

This is probably the thing I'm most proud of about ZTools — your data never leaves your browser. 🔒

Here's the privacy model:

• 🛡️ Client-side processing — the vast majority of tools run entirely in your browser using JavaScript

• 🚫 No server uploads — your files, text, code, and data are never sent to any backend

• 🚫 No data collection on tool usage — we don't track what you paste, convert, or generate

• ✅ No account required — most tools work without signing in at all

• 🔐 Google sign-in is optional — only needed if you want features like favorites sync and collections

• 📱 Works offline — PWA-capable, so once loaded, many tools work without internet

I built ZTools because I was tired of pasting sensitive JSON payloads and API keys into random websites that "promise" not to store them. With ZTools, there's literally no server to store them on — it all processes locally.

"The most secure server is the one that never receives your data." 🛡️
