Chapter 02

Privacy & Security

Locks, hidden chats, screenshots, disappearing messages, and who-can-see-me controls.

Disappearing messages

What is it?

Messages that delete automatically after a chosen duration.

Where?

Chat → person name (top) → Chat info
  → Disappearing messages
    → choose duration (for example 24 hours, 7 days…)

How it works

Turn on the timer for that chat
Each new message starts the countdown
When time ends, it is deleted on both devices

Screenshot blocking

What is it?

Block screenshots or screen recording inside the chat — for both sides.

Where?

Chat → name/photo (top)
  → Chat info
    → scroll down → Advanced WenYou
      → Block screenshots

Works only for online WenYou chats — not SMS.

State	What you see
Off	Photos and sharing allowed
On	Screen protected from shots and recording — both sides
The other person enabled it	The other party enabled protection — you cannot capture the screen

Chat lock

What is it?

Protect a chat with a 4-digit PIN or fingerprint — asked every time you open it.

Where?

Chat info → Chat lock → enable

Home → long press a chat → Lock

First time: create a 4-digit PIN. Without the correct PIN you do not see the messages.

App lock

What is it?

Lock all of WenYou — PIN or fingerprint when opening the app.

Where?

Settings → Privacy → App lock

Hidden chats

What is it?

Hide sensitive chats — they do not appear in the list until you enter a PIN.

Where?

Home → tap the word WenYou (app title at the top of the list)
  → enter PIN → Hidden chats

Hide a chat: long press → Hide.

Who can see me

Where?

Settings → Privacy → Who can see me

Controls: profile photo, last seen, online status, bio, story. Each can be Everyone / Contacts / Nobody, plus exceptions.

Block and filter

Where?

Settings → Privacy → Block and filter

Block a number: they cannot send/receive with you
SMS filter: keywords → matching SMS is hidden automatically

Verify encryption (Safety Number)

Where?

Chat info → Verify encryption

Compare a number/QR with your friend's device. If they match, the chat is not intercepted.

Delete account

Settings → scroll down → Delete account. Choose a reason, type a confirmation phrase, and solve a math check. Account is deleted from the server plus local data.

Per-Contact Privacy Controls

WenYou offers granular privacy controls that can be configured individually for each contact.

Control	Per contact
Online status	Show or hide independently
Last seen	Show or hide independently
Who can call you	Allow or block calls from that person
Who can send voice messages	Allow or restrict that person
Who can see status / stories	Show, hide, or mute their stories / yours

Hide, mute, or block one person

Hide stories from a specific person, mute a specific person, hide notifications from a specific person, or block a specific person or number. Global “Who can see me” settings still apply; per-contact rules are the exceptions.
