The system of record for how work actually happens.

Privacy is our
fundamental feature.

We don't just have a privacy policy. We have a privacy architecture.

No Cloud Processing

Most utility sites upload your files to their servers for processing. FyTools does the opposite. We download our processing engine to your browser once, and then every conversion happens 100% locally on your machine.

We See Nothing

Because processing is local, your data is never sent to our servers. We never see your PDFs, your images, or your text inputs. Your passwords stay as hashes and your files stay as bits on your own drive.

The technical details

We leverage **WebAssembly (WASM)** and the **Web Cryptography API** to provide high-performance computation without server-side interaction. This isn't just better for privacy—it's also significantly faster because it eliminates the latency of uploading and downloading large files.

  • Zero Data Collection: We do not collect personal identifyable information (PII) during your utility sessions.
  • Anonymous Usage: We use privacy-preserving analytics that only show us which tools are popular, never who is using them.
  • Stateless Processing: Once you close the tab, all temporary data used for processing is wiped from your browser memory.
