# How it works: your files and your privacy | Nimbo

> What happens to a file in Nimbo's free web tools and in the iPhone app: what stays on your device, what is sent and when, and how to check it yourself.

Private by design

# What happens to your files

A plain account of where your documents go when you use Nimbo, in the browser and on iPhone, and how to check it yourself.

## Web tools: processed in your browser

1. The page loads the tool's code from this site: Nimbo's own scripts and the open-source libraries pdf-lib and PDF.js.
2. When you choose a file, your browser reads it into the memory of the tab. It is not sent anywhere.
3. The tool builds the result in the same tab, and the download button saves it straight from that memory.
4. Closing or reloading the tab discards the files and the results. No server keeps a copy, because none ever received one.

Because the work happens on your device, its memory sets the limit: a phone may struggle with a file of several hundred megabytes that a computer handles easily.

## Check it yourself

Open your browser's developer tools, choose the Network tab and run any tool: the page's scripts load from this site, and no request carries your file. The site's security policy only allows scripts served by the site itself.

## This website

No account, no analytics, no ads and no cookies. Like any website, the server that delivers the pages receives the technical data of each request, such as your IP address and the address of the page; your files are never part of these requests.

## The iPhone app

- Scans, photo and file conversions, signatures and compression run on the iPhone.
- The AI features (create, transform, translate, ask) work on a server: the text they need is sent only when you use one, after Nimbo asks your permission. Requests are not stored, and generated documents are deleted within 24 hours.
- No account. Subscriptions are handled by Apple through the App Store; Nimbo never sees your payment details.

## Free on the web. *Even better on iPhone.*

The web tools cover the basics. The app does the rest, right where your documents are.
