Session PIN
Turn on app lock from Account. Until you enter the correct PIN, the inbox and threads stay closed.
App lock
PIN-lock Chatkode before anyone else opens it.
After you claim, enable an app lock PIN so encrypted Match and 1:1 chats stay behind a gate on a shared phone, borrowed laptop, or desk you step away from. Chatkode can re-lock after idle time too.

Separate from Hidden chats PIN & decoy
Auto re-lock
Step away and Chatkode can lock again after idle time — so an open browser tab is not an open conversation.
Works with Hidden
App lock covers the whole app. Hidden chats add a second PIN (and optional decoy) for threads you tuck away.
Why app lock improves your life
Encryption protects message content. App lock protects the open session after you claim — on a phone you hand to someone else, a café laptop, or a family tablet. Fewer accidental peeks into Match and private threads.
When to turn it on
- You share a device with housemates or family.
- You travel and unlock devices in public places.
- You keep Chatkode Match open in a browser tab at work.
Pair with hidden chats for sensitive threads and shared-device guidance. Help steps: privacy locks help.
Honest limits
App lock is not a full-disk encryption product and does not replace your device passcode. Use both. It also does not stop screenshots or someone who already knows your PIN.
App lock FAQ
Does app lock replace end-to-end encryption?
No. End-to-end encryption helps keep conversations private in everyday use. App lock protects access on the device in front of you.
Can I lock a single chat?
Yes — Chatkode also supports a per-chat PIN from the conversation menu, in addition to whole-app lock and Hidden chats.
