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.

Is there a mobile app or is this web-only? I'd love to have tools on my phone?

Great news ZTools is available on Android too!

Here's where you can use ZTools:

Web App full experience at https://ztools.zaions.com, works on any browser
Android App available on Google Play Store (search "ZTools" by Zaions)
Browser Extension Chrome Web Store ("ZTools - Utility Tools") for quick access from any tab
PWA Support install from the browser for a native-app-like experience

All three surfaces share the same tool library, so you get the full 484 tools whether you're on desktop, mobile, or using the extension. Your favorites and settings sync across devices if you sign in with Google.

484 tools is wild — what categories are covered and how are they organized?

Thank you and yes, 484 is not a typo!

Here's how the toolbox is organized across 17 categories:

Text Tools formatters, case converters, counters, diff checkers, encoding/decoding
Code Tools JSON formatter, minifiers, beautifiers, regex testers, code cleanup
Calculators math, finance, percentage, unit converters, date calculators
Design Tools color pickers, palette generators, gradient builders, CSS helpers
Data Tools CSV/JSON converters, data generators, table formatters
Image Tools resizers, compressors, format converters, filters
Generators lorem ipsum, passwords, UUIDs, QR codes, dummy data
Finance Tools loan calculators, tax estimators, currency converters
Conversion Tools units, currencies, time zones, number systems
Security Tools hash generators, encoders/decoders, encryption helpers
Education Tools GPA calculators, study aids, reference tools
Media Tools audio/video helpers, file tools
Legal Tools document helpers, compliance references
Productivity Tools timers, planners, workflow helpers
Web Tools meta tag generators, SEO helpers, URL utilities
Mobile Tools responsive testers, device previews
Utility Tools everything else that doesn't fit neatly elsewhere

The smart search makes it easy to find exactly what you need just start typing and the most relevant tools surface instantly. No digging through menus.
