George and George Business apps cannot be installed on devices that have been unlocked (i.e. rooted or jailbroken). Such systems pose increased security risks, so they are not supported.
Why is it important to update the operating system?
- Operating system updates offer new features, but more importantly, they provide security patches from the manufacturer which help protect your data and finances.
- Using a mobile phone or tablet with an outdated operating system can increase the risk of attack.
- Please check the list of unsupported devices that are no longer compatible with the current versions of George and George Business. If your device is listed, consider upgrading to a newer model that supports the latest security updates.
- For more tips on how to use the George and George Business apps safely, see our Security guidelines below.

Security guidelines for using
George and George Business
Install apps exclusively from official stores like the App Store, Google Play, or the official store of your device manufacturer. Never download software from unverified sources. Use only original operating systems and avoid modifications that allow full administrative access (such as rooting or jailbreaking). Do not purchase or use such modified devices. If we detect malware on your device, we may restrict or revoke access to the banking applications.
Your PIN must consist of 4–8 digits. Choose a PIN that you can easily remember but is difficult for others to guess. Do not share your PIN with anyone and change it regularly. You can also use biometric authentication to access the apps. We recommend using this option for enhanced security if your device supports it.
You can secure your George or George Business access using biometrics in two ways: fingerprint identification or facial recognition.
Fingerprint identification:
You can use fingerprint identification to secure both your device and application access. Ensure no other individuals' fingerprints are registered on the device. If there are any, please remove them.
Facial recognition:
You can also protect your device and app access with facial recognition. However, if you have a similar-looking sibling or twin, this method is not reliable. You should also evaluate the security of this method based on the technology that the manufacturer used for the actual face scanning.
Use primarily mobile data when accessing the banking apps. Free and open Wi-Fi networks may expose your sensitive data (e.g. login details) to unauthorized access and misuse. You can use George and George Business apps even when you are offline.
You can install the apps on multiple devices. However, keep in mind that if you share a device with another person (be it a family member or a friend), they may gain access to your banking apps. Therefore, you should install the apps on devices that are exclusively used by you.
Use modern security features like fingerprint identification. If unavailable, set a different PIN code to access your device than you use to access the George or George Business apps.
If the banking app prompts you to confirm a transaction or login that you did not initiate, do not authorize it, but inform us immediately about it. You can contact us directly from George (it is quick and safe) or call us on 277 207 207.
Install antivirus software on your mobile device and keep it up to date along with the operating system.
If your device is lost or stolen, use features to locate, lock, or remotely erase its data. On Android devices, use "Find My Device." On iOS devices, enable "Find My iPhone" in Settings. Refer to your device's user manual for detailed instructions.
If you suspect misuse of your online or mobile banking, contact us immediately via George. You can also call us on 277 207 207 or email us at csas@csas.cz. For more information, visit Česká spořitelna's website.
