How File Processing Works

Your files stay on your device

When you select a file in a FinSafe PDF tool, it is loaded into your browser's memory on your own device — and that is where all the work happens. Merging, splitting, signing, adding page numbers, comparing contracts: every step runs locally in your browser. Your file is never sent to a FinSafe server or to any third party.

What happens when you close the tab

Files held in browser memory disappear when the page is closed or refreshed. There is no server copy to delete, no queue your file sits in, and no trace left with us — because nothing was ever transmitted. The only copies that exist afterwards are the ones you chose to save to your own device.

What this means in practice

This design has real, practical consequences:

• A contract full of personal and financial details never leaves your device while you work on it
• We cannot see, recover, or restore a file for you — if you close the tab before saving your result, the work is gone
• Processing speed and the maximum practical file size depend on your device's memory, not on our servers
• Once the tool page has loaded, the processing itself does not depend on sending your data anywhere

The honest limits

A few of the tools listed on FinSafe — such as automatic contract summarizing and translation — are not live yet, and their pages say so plainly along with a manual method you can use today. For every tool that is live, the rule above holds without exception: your files are processed in your browser and never uploaded.
