FAQ
Frequently asked questions
Is my work saved?
Your last document is saved in this browser only. Nothing is uploaded.
Is my data uploaded anywhere?
No. Everything runs locally in your browser — nothing you paste or open is sent to a server, logged or stored. The tool keeps working offline once the page has loaded.
