## What is cryptoscreen?

cryptoscreen is a private note app for messages that should not last.

Write a note, choose a six-digit PIN, and cryptoscreen encrypts the message on your iPhone before it leaves the device. Share the generated link and send the PIN separately. The recipient opens the note once, then the encrypted server row is consumed.

What cryptoscreen does:
- Encrypts notes locally before upload.
- Requires both the link secret and the PIN to open a message.
- Deletes normal message rows after one successful read.
- Destroys the message after the third wrong PIN attempt.
- Expires unopened links after the retention window.
- Uses a guarded reader that reduces casual screen exposure.
- Wipes the visible reader session if iOS reports a screenshot.
- Supports encrypted image attachments with Pro for senders.
- Supports App Clip opening for lightweight receiving.

cryptoscreen is designed to avoid accounts, profiles, contact lists, and message plaintext on the server. The production service stores encrypted bytes, encrypted image attachment objects when supplied, attempt metadata, and expiry metadata. Screenshot protection is best-effort: iOS reports normal screenshots after capture, and no app can protect against external cameras or compromised devices.

### 5/5 — Something I’ve never seen before

*2026-06-30*

Really cool concept. I’ve tried to use it in my regular routine, asking my buddies to try it by sending each other secret messages.
Looking forward to other features and how it’s going to look in the long run.

## Frequently asked questions about cryptoscreen

### How does cryptoscreen protect my notes?

cryptoscreen encrypts your notes locally on your iPhone before they are uploaded. Access requires both a unique link and a six-digit PIN, ensuring only intended recipients can view the message.

### What happens after a note is read?

After a note is successfully opened once, the encrypted server record is consumed and deleted. This ensures the message is truly temporary and cannot be accessed again.

### Can cryptoscreen prevent screenshots?

cryptoscreen attempts to detect screenshots and will wipe the visible reader session if iOS reports a screenshot. However, this protection is best-effort and cannot prevent external cameras or compromised devices.

### What happens if someone enters the wrong PIN?

If the incorrect PIN is entered three times, the message is destroyed. This adds an extra layer of security against brute-force attempts.

### Does cryptoscreen have ads?

No, cryptoscreen does not contain advertisements. It is a free application designed for privacy without interruption.

### Is cryptoscreen available on other devices besides iPhone?

Currently, cryptoscreen is supported on iPhone devices. The app utilizes App Clip functionality for lightweight receiving on compatible iOS devices.

### How long are unopened links kept?

Unopened links in cryptoscreen expire after a defined retention window. This ensures that old, unread messages are automatically removed from the server.

### What is the update frequency for cryptoscreen?

cryptoscreen was last updated on June 29, 2026, with version 1.0.1. The developer actively maintains the application, suggesting regular updates for improvements and security.
