Images often contain sensitive information: ID documents, medical records, confidential contracts. When using OCR, privacy matters.
The Privacy Problem
Most online OCR tools:
- Upload your image to their servers.
- Process it remotely.
- Store it (temporarily or permanently).
- Send results back.
Your sensitive images travel across the internet and sit on unknown servers.
How Rune is Different
100% Local Processing
All OCR happens in your browser using JavaScript and WebAssembly. Your images never leave your device.
No Upload Required
The file is read locally, processed locally, and results displayed locally.
No Server Involvement
Rune's servers never see your images. Processing is completely client-side.
No Data Storage
Nothing is saved anywhere. Close the tab and all data is gone.

|---|---|---|
| Image Upload | None | Required |
| Server Processing | None | Yes |
| Data Storage | None | Often cached |
