The Problem
You're halfway through a long form — maybe a job application, an insurance quote, or a school registration — and you accidentally close the tab. Or the page crashes. Or your session expires.
Everything you typed is gone.
Browser autofill only covers the basics (name, email, address). It doesn't save the custom fields, text areas, or dropdowns that make up 90% of real forms.
What I Built
FormVault is a Chrome extension that automatically saves everything you type into any web form — locally, on your machine. No accounts, no cloud sync, no network requests at all.
When you come back to a form, FormVault lets you restore your previous inputs with one click.
How it works:
- Detects form fields on any page
- Saves inputs to Chrome's local storage as you type
- Restore button appears when you revisit a page with saved data
- All data stays on your device — zero network requests, ever
Why I built it this way
I wanted something I'd actually trust with sensitive form data. Most form-saving tools either sync to a cloud or require an account. FormVault does neither. You can read every line of the source code yourself.
Try it out
The extension is free and open source. If you've ever lost form data and wanted to throw your laptop, this might save you some frustration.

I'm a cybersecurity student building tools in my spare time, so feedback is genuinely welcome — especially on the privacy/security side. What would you improve?
