Protect the app with app lock
Updated 31 October 2026 · 2 min read · 14 Contents
Plain-language meaning
App lock asks for your fingerprint, face or device PIN before the XMarketRadar app shows your data after a cold start or after you return from another app.
Why it is useful #
It keeps portfolios, watchlists and alerts private on a shared or unattended phone.
Where it appears and the workflow #
In the app open the avatar icon, then Preferences, then App lock, and turn on Lock with biometrics or device PIN. Choose Lock after leaving the app: Immediately (the default), After 1 minute or After 5 minutes. The option appears only on devices that can authenticate. Turning it on or off asks you to authenticate.
Calculation or source #
The app always locks on a cold start and locks again when it returns from the background after the chosen time. Brief interruptions such as the notification shade or a system dialog do not lock it, and trips the app starts itself (sign-in, billing, sharing, printing, file picking) are allowed for up to 10 minutes.
Prerequisites, inputs, period and unit #
Requires a device with a screen lock and the app on Android or iOS. The setting is stored on the device only. No plan is needed.
Worked example #
Illustrative only: with After 1 minute selected, answering a 30-second call does not lock the app, but returning after five minutes shows the lock screen.
What high and low mean #
Not applicable: app lock has no values.
Positive, negative and zero #
Not applicable: app lock has no values.
Limitations and common mistakes #
The app-switcher preview shows a cover instead of your data, but screenshots are not blocked. Notification taps, shortcuts, shares and widget taps wait until you unlock.
Market-specific differences #
Behaviour is the same in every market.
Suggested next steps #
Turn on app lock with After 1 minute, leave the app for longer than a minute and confirm the lock screen appears.
