Starting on version 10.3.0, we have made adjustments to align with the Play Store’s policies, which resulted in the reduction of some features.

We value your feedback and are actively working on solutions to enhance our users’ experience. Thank you for your understanding and support as we strive to deliver the best security app there is.

Different reasons may influence the payment being declined by the Google Play Payment System:
To try to fix this problem, you can follow these tips from Google Play:
1) Consult Google Center on how to fix payment issues, click here.
2) Call your credit card issuer to verify your identity and confirm the purchase;
3) Make sure your name, address, and payment information are up to date in your Google Play Store account.
Another tip that can be useful: try to make the purchase using your Google account through the cell phone of a friend or family member and, if you process normally, then just install dfndr security with this same account on your cell phone so that the signature is recognized
Please remember that our Anti-hacking requires the Android’s Accessibility permission always be active to work properly.
If you are receiving alerts to enable the Anti-hacking even after having already activated it and granted all permissions, this indicates that other app, battery saving settings or failure/conflict in your Android may be turning some important permission off inappropriately.
To try to resolve this, please uninstall/reinstall dfndr security and, after reinstalling, click here from your device to enable the Anti-Hacking, also granting the Accessibility permission to dfndr security once again.
It would also be helpful to try:
A – enable the Notification Access permission for dfndr security to try to avoid other apps or Android’s battery optimizing system turning off permissions from dfndr security. To grant this permission, open your device’s Settings app > Applications > Three dots at the top right > Special access > Select the dfndr security app on the list to activate and, it’s done!
B – disable the option to turn off permissions when the app is not in use by following these steps: open your device’s Settings app > Applications > dfndr security > Permissions > Scroll down and disable the option “Remove permissions if app isn’t used”.
C – check Android battery optimization (usually under Settings>Battery or Power) and tap on dfndr security to not be optimized.
D – disable Android battery saver settings (usually under Settings>Battery>Battery Saver).
E – on Android 8.0+, you can long-press on the app from the Overview menu (or just swipe up) to lock the app. This will lock dfndr security app and prevent it from getting killed by the system and will remain in the Overview section until you choose to unlock it.
If even after following the steps above, the Accessibility permission or Anti-hacking switch persists to be “auto-disabled”, please write us at support@psafe.com

We know that this information may appear to be a possible exposure of your network, but this does not necessarily indicate vulnerability, but rather it is only intended to inform the user which are each of the open ports on your network.
We are unable to indicate how to close your router’s ports through this function as this will depend on the model of each cell phone / router. Therefore, to understand the functioning of your router’s ports and check for possible vulnerabilities, we recommend that you seek this information directly from the manufacturer’s manual of this device or from the technical support, informing the exact model of the router.
The best way to protect your Wi-Fi is by changing your Wi-Fi password.
The ‘Wi-Fi network password’ is the password that you use to join the wireless network. Unless you’ve set your network to “No security”, you are already using a wi-fi network password.
If you’re using the router’s default password or a memorable one that you’ve set yourself, then you should consider replacing this password with a strong password. Remember, that we do not consider the router’s default password to be strong.
To upgrade the wi-fi network’s password, find the WIRELESS settings, usually located in the BASIC section.
Also, you can change the name of your Wi-Fi (SSD) to something other than the modem default.
Example: do not leave TPLINK2934S as the name of your wi-fi. People can know your router and possibly find loopholes easier or even see the default password (if you left the default)
Also, try not to use WEP encryption which is weak, and change your password periodically.
The Wi-Fi Theft Alert function does not block access from unknown devices or hackers on your network, but only informs you which devices are currently connected to your network.
The reason there is a device connected to your wi-fi could be:
Depending on how your router stores login information, the unknown devices connected can be smartphones, appliances such as your smart tv or your refrigerator, and other devices belonging to people who have visited your home previously.
Also, it could mean that someone who shouldn’t have access to your wireless network is accessing the Internet. So if you cannot identify the device, I recommend that you change your password for your Wi-Fi.
