Privacy Policy
Last updated July 2026.
Your files never leave your browser
Celtrim reads and renders your spreadsheet entirely on your device, using JavaScript running in your browser. The file you open, and the cells you select, are never uploaded to a server — we have no copy of them and can't see them.
What we don't collect
We don't use analytics, tracking scripts, or advertising cookies. We don't create accounts, and we don't store spreadsheet contents, file names, or exported images anywhere.
Hosting logs
Like any website, our hosting provider may keep basic server logs (such as IP address and request time) for security and reliability purposes. These logs are not linked to spreadsheet contents, since that data is never sent to us.
Changes to this policy
If this policy changes, we'll update this page and adjust the date above.
