Frequently Asked Questions
▶How can I send a WhatsApp message without saving a contact?
Paste any text containing phone numbers into NumSwift. It extracts the numbers automatically using Google's libphonenumber library, which supports 200+ countries and 15+ number formats. Then click the WhatsApp button next to any number to open a direct chat — no need to add them to your contacts first. WhatsApp is used by over 2 billion people worldwide, so this works for the vast majority of numbers you'll encounter.
▶Does this work on both iPhone and Android?
Yes. NumSwift works in any modern browser on iPhone, Android, and desktop — no app installation required. When you click the WhatsApp button, it uses an official wa.me deep link that opens the WhatsApp mobile app on phones or WhatsApp Web on desktop browsers. The correct behavior is determined automatically by your device.
▶Do I need to install anything to use this?
No installation required. NumSwift runs entirely in your browser as a web application. Just paste your text, extract numbers, and tap the WhatsApp button. All number parsing and validation happens client-side using JavaScript, which means it works offline after the initial page load and processes numbers in under one second.
▶Is it safe to use? Will my data be stored?
Completely safe and privacy-first. All processing happens locally in your browser using client-side JavaScript — no phone numbers or pasted text are ever sent to any server. Extracted numbers are stored only in your browser's localStorage on your own device and are never transmitted externally. You can clear them at any time.
