Can’t Sign In on Android

To keep our service safe for everyone,
FamilyLog automatically checks whether your device is in a secure state.

If you can’t sign in, please check the following setting.

Play Store > Settings > “Play Protect certification”

Based on this check, some app features may be unavailable in cases such as:

• The device hasn’t received security updates for an extended period
• The device has been modified (rooted or running custom software)
• The device is not officially certified

Security requirements are getting stricter from May 2025 onward, so devices that haven’t received a security update in over a year may not be able to use the app.

What to do:

• Check for software updates on your device.
• Applying the latest security patch may restore access.
• If you still can’t use the app after updating, please contact support.

Thank you for your understanding and cooperation in helping us keep the service safe for everyone.
