## What is Teth3r?

Your contact info is outdated before you hit send. New job? New city? Traveling with a temp SIM? You're stuck messaging everyone individually—again.

Teth3r fixes this forever.

Create one living contact card. Share it once. When you update your phone, email, or address, everyone who has your card sees the change instantly. No re-sharing. No "hey, my new number is..." texts. Just automatic sync.

THE PROBLEM WE SOLVE

Traditional contact sharing is broken. vCards become stale the moment you send them. NameDrop is one-and-done. LinkedIn doesn't have your personal number. Every life change means repeating yourself to dozens of people.

Teth3r keeps everyone synchronized automatically.

HOW IT WORKS

1. Create your card with phone, email, address, and socials
2. Share via link, QR code, or the iOS share sheet
3. Recipients view your card instantly at teth3r.me - no app required
4. Update your info anytime. Everyone sees changes immediately.

KEY FEATURES

- Beautiful Web Cards
Your card lives at teth3r.me/yourname. Anyone can view it, tap to call, tap to email, or save to contacts - without downloading anything.

- Smart Permission Tiers
Control exactly who sees what. Share your work email with colleagues, home address with family, and personal number with close friends. Different info for different people.

- Real-Time Sync
Changed your number? Moved to a new apartment? Update once, sync everywhere. People with your card always see your current info.

- Push Notifications
Get notified when someone you follow updates their card. Never miss an important contact change again.

- Traveler-Friendly
Perfect for digital nomads and frequent travelers. Share your temporary local SIM once instead of texting 50 people. Set expiration dates on temporary numbers.

- Privacy First
No tracking SDKs. No ads. No data selling. Your information stays yours. Export or delete your data anytime with one tap.

PERFECT FOR

- Travelers managing temporary phone numbers abroad
- Anyone starting a new job or moving cities
- Professionals who want separate work and personal contact info
- People tired of repeating "my new number is..."
- Anyone who values their privacy

Share once. Update everywhere. Stay connected effortlessly.

Download Teth3r and create your living card today.
