Somebody Make This: A browser extension that auto-fills forms with temporary, self-destructing contact info I was selling an old monitor on Facebook Marketplace last week and for the tenth time, I hesitated before typing my real phone number into the message. It got me thinking about this universal privacy problem. The Problem: We all need to share info like phone numbers or emails temporarily, but once we type it into a website, it's there forever. This happens on marketplace apps, sign-up forms, etc. I'm tired of getting spam calls months after selling anything on any of those platforms The Idea: "Auto-Expire" - A Browser Extension Imagine a little icon in your browser bar. When you click on a form field for a "phone number" or "email," you click the icon and it instantly generates a temporary, burner number/email that routes to you. The key feature: you set a timer (1 hour, 1 day, 1 week), and after that time, the number deactivates permanently. · For sellers: Give a buyer a number that works for 24 hours, then becomes useless. · For sign-ups: Use a temporary email for a "free trial" that self-destructs, preventing spam. It would be seamless, built right into the browser, and would make ephemeral sharing the default instead of a hassle. Why it might work: · Solves a real, daily pain point. · Uses existing APIs (like Twilio for numbers) so it's technically feasible. · Better than separate burner apps because it's integrated right where you need it. I have no idea how to build this, but I wanted to see if this is just a "me" problem or if others would find it useful. · Would you use something like this? · What's the most frustrating situation where you've had to give out your real info? · Am I missing any major drawbacks? Thanks for the feedback!
