What stays in your browser

  • The text you paste and the phone numbers found in it. Extraction, conversion and validation run in your browser. This content is never sent to us or to anyone else.
  • Your list of extracted numbers, a running count of how many you have extracted, your default country (the one you chose, and the one we detected) and your light/dark preference. These are kept in this browser's local storage so they are still there when you come back. “Clear all” empties the list; clearing site data in your browser removes everything. Anyone else using the same browser profile can see the list.

What leaves your browser

  • Links you click. Call, text and WhatsApp buttons hand that one number to your phone app, your messaging app or WhatsApp, the same as tapping a phone link on any website. The person you contact sees your own number, as with any call or message.
  • Your country, once. On your first visit the page asks our own server which country the request came from, to pick a sensible default country. Our host derives this from your IP address; we do not store the address or the answer on our side. The answer is kept in your browser, so later visits do not ask again, and once you have chosen a country yourself the page never asks.
  • Anonymous usage analytics. We use Vercel Web Analytics, Vercel Speed Insights and Umami to see which pages are visited, how fast they load and which buttons are used. Events can include a count (for example how many numbers were extracted) and your default country code. They never include the text you pasted or any phone number. These tools do not use cookies and do not identify you across sites.
  • The contact form. If you write to us, your name, email address and message are sent through Web3Forms and delivered to our inbox. We use them only to reply.
  • Server logs. Like every website, our host (Vercel) processes your IP address and browser details to deliver pages and keep the service secure.

What we do not do

  • No accounts, no advertising, no selling or sharing of personal data.
  • No cookies set by NumSwift.
  • No copy of your numbers on any server.
