Privacy
Your data stays on your device
vjyas.online is built so you can format JSON, decode JWTs, and run developer tools without sending sensitive input to our servers.
Tool input is private
Everything you paste or type into a tool is processed in your browser. We do not receive, store, or sell it.
Optional page analytics
We may count page views to see which tools are useful. Analytics measure traffic — not what you type.
No ads
The site does not show ads and does not load advertising scripts or networks.
How vjyas.online works
Each tool runs as a static page with client-side JavaScript. When you format JSON, decode a JWT, or generate a password, the computation happens on your computer or phone — not on our backend.
We do not ask you to create an account. We do not operate APIs that accept your tool payloads.
What we never collect
- Text, JSON, YAML, XML, JWTs, passwords, or any content you enter in tools
- Tool outputs produced from your input
- Share-link payloads in URL fragments (
#s=...) — fragments are not sent to servers
What may be collected
| Data | Why | Where it lives |
|---|---|---|
| Page views & referrers | Understand popular tools and improve the site | Privacy-focused analytics (e.g. Cloudflare Web Analytics), when enabled |
| Theme preference | Remember light/dark mode | Your browser localStorage |
| Privacy banner dismissal | Do not show the notice again | Your browser localStorage |
Analytics
If enabled in production, we use privacy-oriented page-view analytics — for example Cloudflare Web Analytics. This helps us learn which tools people use so we can prioritize improvements.
Analytics does not include the content you paste into tools. It measures visits, page loads, and similar site-level signals.
Third-party services
- Google Fonts — typography may be loaded from Google’s CDN
- Analytics scripts — loaded only when enabled via environment configuration
- Tool libraries (Prettier, etc.) — bundled into the site and executed in your browser
Your choices
- Clear site data in your browser to reset theme, cache, and banner preferences
- Use browser privacy tools or extensions to block analytics if you prefer
- Share tool state via URL hash only with people you trust — anyone with the link can decode the fragment
