Guard your entire reading sanctuary. Require a master PIN, fingerprint, or facial recognition scan every time GemReader is launched.
Why Enable App Lock?
Your reading list and study notes reveal your deepest intellectual interests, personal reflections, and creative projects. Even if your phone has a general lock screen, there are many times when you lend an unlocked phone to a colleague or family member.
App Lock establishes a dedicated protective barrier around GemReader itself. By requiring a master PIN, fingerprint, or facial recognition scan upon opening, you ensure that your reading sanctuary remains completely confidential.
What You'll Need
Before setting up App Lock, make sure you have:
• **Platforms**: GemReader running on Android or iOS. • **Hardware**: A device equipped with fingerprint recognition, Touch ID, Face ID, or system PIN hardware. • **Security**: A 4-digit numerical code for your master app PIN.
Step-by-Step Instructions
1. Open GemReader and tap the gear icon in the library header (or tap **⋮** -> **Settings**). 2. Scroll down to the **Security & Privacy** section. 3. Tap **App Lock** and toggle the feature **On**. 4. Enter a 4-digit master PIN on the keypad, then re-enter the same PIN to confirm. 5. Toggle **Enable Biometrics** to allow quick unlocking with your fingerprint sensor, Touch ID, or Face ID. 6. Tap **Lock Timeout** to choose how quickly the app re-locks after you switch away: select **Immediately**, **After 1 Minute**, or **After 5 Minutes**. 7. Exit the app and reopen it to test your configuration: the biometric prompt or PIN keypad will appear smoothly.
Helpful Tips & Common Questions (Librarian's Advice)
• **Master PIN Fallback**: If lighting conditions make facial recognition difficult or your fingers are damp, you can always tap **Use PIN** to enter your master numerical code. • **Automatic Multitasking Shielding**: Enabling App Lock automatically shields GemReader in your phone's recent apps switcher, preventing casual passersby from catching glimpses of your open pages. • **Multi-Layered Security**: App Lock protects access to the entire application, while individual Locked Libraries inside can still maintain their own distinct PINs for defense-in-depth protection.
