FormVault

Auto-saves web form data locally and lets you restore it if a page crashes, refreshes, or you navigate away.

Ever lost a long job application, contact form, or survey because the page crashed, refreshed, or you accidentally hit the back button? FormVault makes sure that never happens again. It runs quietly in the background, automatically saving everything you type into web forms. If something goes wrong, FormVault detects your saved data when you return to the page and offers to restore it with one click. No accounts. No cloud. No setup. Just install and your forms are protected. ━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS 1. You fill out a form like you normally would 2. FormVault silently saves your input every few seconds 3. If the page crashes, refreshes, or you navigate away — your data is safe 4. When you return, a small notification asks if you want to restore 5. Click Restore. Done. ━━━━━━━━━━━━━━━━━━━━ FEATURES • Automatic saving — saves form data every 3 seconds as you type, no manual action needed • One-click restore — a small, non-intrusive notification appears when saved data is available • Works on modern web apps — fully compatible with React, Angular, Vue, and other SPA frameworks • Dynamic form detection — finds fields even when they load after the page (AJAX, single-page apps) • Search and browse — find any saved form by page title, URL, or what you typed • Copy to clipboard — export all saved field values as formatted text • Configurable auto-delete — automatically clean up old saves after 7, 30, or 90 days • Domain blocklist — exclude specific websites from being saved ━━━━━━━━━━━━━━━━━━━━ PERFECT FOR • Job applications on Workday, Greenhouse, Lever, LinkedIn, and Indeed • College and university application forms • Long contact forms and customer support tickets • Government and immigration forms • Insurance claims and medical intake forms • Surveys and questionnaires • Any form where losing your progress would ruin your day ━━━━━━━━━━━━━━━━━━━━ PRIVACY FIRST FormVault was built with one rule: your data never leaves your browser. • 100% local storage — everything stays on your device • Zero network requests — no servers, no cloud, no APIs • No account required — works instantly after install • No analytics or tracking of any kind • Sensitive fields are never saved — passwords, credit card numbers, and SSNs are automatically excluded • Banking and financial sites are excluded by default Your privacy is not a feature.
