Privacy & cookies

This page explains what happens to your data when you use OpenToolbox. The site is run by the operator of OpenToolbox, the data controller for the processing described below.

Your files never leave your device

Every tool runs inside your web browser. Files you open are read and processed by your own device and are never uploaded to our servers or to anyone else. We cannot see them and keep no copy; closing the tab discards them.

How it works

The site is static: pages, scripts, WebAssembly modules and fonts are served as plain files. There is no backend that could receive your files.
When you choose a file, your browser reads it into memory. The tool processes it there, on the page itself or in a background worker, with WebAssembly and, for AI tools, WebGPU when your browser supports it.
Results are created on your device and saved through your browser's normal download. Nothing is sent back to us.

Every network request, and why

These are the only servers your browser contacts while you use the site:

This site. Pages, code, fonts and other static files. The site is hosted by Hostinger (Hostinger International Ltd, Cyprus, in the EU), which acts as our data processor and, like every hosting provider, may keep short-lived server logs (IP address, browser, pages requested) for security and operations.
Hugging Face (huggingface.co), AI tools only. The first time you use an AI tool, your browser downloads the open-source model files (not your data), pinned to a fixed version; Hugging Face may deliver them from its download servers under hf.co. The browser then keeps them in its cache, so they are not downloaded again. Hugging Face receives a normal web request, including your IP address.
OpenFreeMap (tiles.openfreemap.org), map viewer only. The GIS viewer loads background map tiles (OpenStreetMap data) for the area you look at. Your own map files are never sent, and with “No basemap” no tiles are loaded.
Google, only when ads are on. Ads are currently off, so no advertising or consent script is loaded. If we turn them on, they will load from Google's servers as described under Advertising below.
Content you ask for. A few tools can load web content from addresses you provide, only after you turn it on: for example remote images in the Markdown editor or HTML to PDF. Links you click take you to other websites, as on any site.

Nothing else: the site includes no analytics or tracking scripts of its own.

Library telemetry is blocked

Some open-source libraries report usage statistics by default. MediaPipe, which the passport photo maker and face swap use to find faces, sends anonymous usage data (task type, timings, operating system) to Google every minute. We answer those requests inside your browser with a refusal, so nothing is sent and the library stops trying. Libraries that would fetch code or fonts from public CDNs are set up to load them from this site instead.

Check it yourself

Under every tool, a “Local processing” indicator lists the servers the page has contacted, why, and how many uploads it has made: zero. It watches the page itself; requests made inside background workers (such as AI model and map tile downloads) are visible in your browser's developer tools.
For the full picture, open your browser's developer tools (F12, or Cmd+Option+I on a Mac), select the Network tab and use a tool: you will see only the requests listed above, and none of them carries your file.
Or go offline: use a tool once (for AI tools, until the model has downloaded), then turn off your connection and use it again in the same tab. Most tools keep working, because they don't need the network to process your files.

Advertising

No advertising scripts are currently loaded on this site.

Affiliate links

Some tool pages show “Recommended” products marked as sponsored. If you follow such a link and buy something, we may earn a commission at no extra cost to you. We do not share any data with the partner; once you are on their site, their own privacy policy and cookies apply.

Cookies and local storage

OpenToolbox itself does not use tracking cookies. Some tools remember your settings or drafts in your browser's local storage, and AI tools keep downloaded models in the browser's cache. All of this stays on your device, and you can clear it in your browser settings.

Your rights

Under the GDPR you can ask for access to, correction or deletion of personal data about you, object to processing and withdraw consent at any time. Because tool files are never uploaded, we hold no copy of them. For advertising data contact Google through the links above. You can also complain to your local data protection authority.
