Privacy
Cellenix is built to need as little of your data as possible. Here is exactly what happens when you upload a file.
What I see
Your .xlsx file itself never leaves your browser. It is parsed locally, and only the extracted cell values, formulas, and sheet names are sent to my server for analysis. Formatting, comments, embedded images, and the original file are never transmitted anywhere.
What I store
There is no database and no disk storage on my end. The site does use your browser's local storage for two small things that never leave your device: a light or dark theme preference, and a count of how many analyses you have run today, used to enforce a daily limit. Once your report is generated and sent back to your browser, I do not keep a copy of it or the data used to create it.
Analytics and tracking
None. Cellenix runs no analytics and no tracking of any kind, on this page or any other.
Where the analysis happens
The extracted spreadsheet content, not the file itself, is sent to Anthropic's Claude API to generate your report. What Anthropic does with that data while processing the request is governed by their own terms, not mine. You can read those here: Anthropic's Commercial Terms of Service.
Hosting logs
Cellenix is hosted on Vercel. Like any web host, Vercel records standard request metadata for every request, such as the method, path, status code, and how long it took, but not the contents of what you send. If something fails on my end, my error logs record the type of failure, not the contents of your spreadsheet.
About this
