SecretCall.net

Instead of a phone number, just a simple 5-digit code. No registration, no account, no address book. SecretCall is the simplest form of private communication — download it, share your code,
and you're ready to receive calls.
🔹 How does it work?

Download the app — you instantly get a temporary 4-digit code
Reserve the code with one tap — and it stays yours
Share it with whoever you want to talk to (via SMS, Viber, or in person)
You can each call one another using your own codes — with no phone number

🔹 What does it offer?
✓ End-to-end encryption (E2EE)
Calls and messages travel encrypted between the two phones. Neither SecretCall's server nor network providers can access the content. The keys exist only on the two devices.
✓ No call log — anywhere
Not on the phone, not on the server. Once a call ends, there's no trace that you ever spoke. It can't be looked up, because it doesn't exist.
✓ No address book
We don't ask for your contact list, and we don't sync anything. SecretCall doesn't know anyone around you.
✓ Messages self-destruct after being read
A message can be read once — after that it's deleted from both the server and the recipient's phone. It can't be retrieved or read a second time.
✓ You can send images too
You can attach up to 500 characters of text + 1 photo to a message. This is also end-to-end encrypted and destroyed after reading.
✓ Crystal-clear sound
Professional SFU technology (LiveKit) powers the audio connection — low latency, fast WebRTC, reliable on both mobile networks and Wi-Fi.
🔹 What do we store?
SecretCall needs just two things to work:

Your reserved 5-digit code — so we can route the caller to your phone
Your push notification token — so incoming calls reach your device

Nothing else. No email. No phone number. No name. No profile. No advertising ID. No analytics.
🔹 What is it good for?
SecretCall is for people who want to handle their communication over a private channel — without having to create yet another account or share their phone number.
🔹 Privacy
