About JustUseIt
Free, privacy-first browser tools — no server uploads, no installs, no tracking.
Our Mission
Most online tools for removing photo metadata or extracting text from documents silently upload your files to third-party servers — often storing them for days, weeks, or indefinitely. We built JustUseIt because sensitive data — your home address embedded in a vacation photo, your medical records in a scanned document, your financial statements in a PDF — should never have to leave your device. Every tool we make runs 100% in your browser using open-source libraries, so you stay in control at all times. No account required, no tracking cookies, no data collection.
How It Works
Everything runs in your browser
When you select a file, it is loaded directly into your browser's memory using standard Web APIs — specifically the FileReader API and the Blob interface. No network request is ever made to our servers — not even a partial upload, not even a thumbnail preview. You can verify this claim yourself in real time: open your browser's DevTools (F12), click the Network tab, and watch for any outgoing requests while you use any JustUseIt tool. You will see none carrying your file data.
No server, no storage, no exposure
Because all processing is entirely client-side, we never have the ability to see, store, or share your files — even if we wanted to. When you close the browser tab, all data is automatically cleared from memory by the browser's garbage collector. There is no server to breach, no database to leak, and no employee with access to your documents. The architecture makes a privacy breach structurally impossible on our end.
Built on open-source technology
We use ExifReader for EXIF metadata parsing, Tesseract.js for OCR text recognition, pdf-lib for PDF manipulation, and OpenStreetMap Nominatim for reverse geocoding GPS coordinates into human-readable addresses. All libraries are open-source and publicly auditable on GitHub — you never have to trust a black box or take our word for it. The full dependency list is available in our repository's package.json.
Technology Stack
JustUseIt is built entirely on open-source, auditable libraries deployed on a global edge network for fast load times worldwide. There are no proprietary processing pipelines, no black-box cloud services, and no vendor lock-in — every dependency can be inspected, forked, or replaced. The full stack is transparent by design.
Our Privacy Principles
- Your files are processed exclusively on your device using browser APIs — they are never transmitted to any server, not even temporarily or partially.
- We collect no personal data, require no account or email address, and set no tracking or advertising cookies. Your usage is entirely private.
- All core processing libraries (ExifReader, Tesseract.js, pdf-lib) are open-source and publicly auditable on GitHub. You can inspect every line of code that touches your files.
- Only GPS coordinates — never photo files or any other file content — are sent to OpenStreetMap's Nominatim API for address lookup, and only when you explicitly click to resolve an address. The photo itself stays on your device.
