Tool inputs (your data)
- Not uploaded — processing happens locally.
- Not stored — no databases for your tool content.
- Not shared — no third-party services receive your input.
What we collect
We do not collect the content you paste into tools, the files you select, or the tokens you inspect. The tools run in your browser and do not send your inputs to any backend.
Like most websites, the server hosting this site may receive basic request metadata needed to deliver pages (for example: IP address, user agent, requested URL, and timestamps). This information is typically present in standard web server logs. ExtraTools.dev does not attempt to enrich, profile, or link that data to your tool inputs.
Site analytics & tracking
- No tracking scripts by default.
- No marketing pixels (no ad networks).
- No session replay tools.
Key principle
If a tool can be done locally, it should be done locally. That's why ExtraTools.dev is built around browser-only execution.
Cookies
ExtraTools.dev does not require cookies to function. If any cookies exist, they are limited to essential technical needs (for example, security or basic preferences) and are not used for advertising or cross-site tracking.
Third-party services
The site is designed to avoid third-party dependencies. If external resources are ever used (for example, a CDN), they are used only to deliver static assets and are not used to transmit tool inputs.
FAQ
Do you upload my files anywhere?
No. Selecting a file happens locally and processing is performed in your browser. Files are not uploaded to ExtraTools.dev.
Do you store JWTs, Base64 strings, or JSON I paste?
No. Tool inputs are not stored on a server, logged, or shared. Your content stays in the browser session.
Can I use these tools with production data?
The tools are designed for that use case because inputs stay local. Still, always follow your company policies and avoid sharing secrets in unsafe environments.
How can I verify that inputs don't leave my browser?
You can open your browser DevTools → Network tab and use any tool. You should not see requests containing your pasted content.
