Privacy Center
How Toolza handles files, telemetry, and third-party code — generated from a live audit of every tool on this site.
File processing behavior
Every Toolza utility is designed to run in your browser. We do not operate an upload API for tool inputs.
Local by default
Files you select are read with the browser File API and processed in JavaScript (often in a Web Worker). They are never POSTed to a Toolza server.
No account required
There is no login, email capture, or profile tied to your tool usage. Favorites and history stay in your browser's localStorage.
Retention
Tool inputs are not retained by us after the page closes. Session analytics events (no file names or contents) live in sessionStorage for up to 100 events and clear when the tab session ends.
What we never collect
Filenames, file bytes, extracted document text, passwords, form answers you type into tools, and personal document content.
Fully browser-only tools
These pages reference no third-party script CDN for core operation — code and processing both stay on your device (plus first-party Toolza assets).
Tools with third-party code libraries
These pages load open-source libraries from a CDN (code only). Your files still never leave the device — the CDN delivers JavaScript, not your data.
What a CDN dependency means
A browser downloads a library (for example PDF.js or a QR decoder) from a public host so the tool can run. That host sees a request for the script file — not the document you opened.

Telemetry & advertising
Honest boundaries around measurement and ads.
Product telemetry
We track a small set of first-party events in your browser session only:
- page / tool open
- file selected (count, size, MIME type — not names)
- processing start, success, error
- download click, search, favorite toggles
What is never sent
- Filenames or file contents
- Extracted text or passwords
- Personal document fields
- Cross-site advertising profiles built from your files
Advertising
Toolza may display ads via third-party ad partners to keep the product free. Ad scripts can set their own cookies or storage under their policies — see our Cookie Policy. Ads never receive the files you process.
Browser compatibility
Core tools target current Chrome, Edge, Firefox, and Safari. Local processing uses standard Web APIs (File, Canvas, Web Workers, WebAssembly where needed). Features degrade gracefully rather than uploading as a fallback.
