Knowledge base

This guide explains why there might be an error during the download, installation, or use of the mobile app SwissTransfer (app for iOS/Android smartphone or tablet).

Device considered insecure?

When using the mobile app SwissTransfer, you might see the message "Your device has been detected as insecure". This message means that the app cannot guarantee that your device is reliable or meets the security requirements.

Indeed, SwissTransfer does not require account creation to function. It relies on integrity mechanisms to ensure that the app is used on a genuine, unmodified device in a secure environment. This system is essential to prevent abuse, fraud, or malicious automation.

On Android, these checks are performed through the "Play Integrity" API provided by Google. If this API returns a result indicating that the device or environment is not reliable, or if it is not available, the device is automatically considered insecure.

Why?

This can happen if the phone is rooted, modified (custom ROM, tools like Magisk), if Google Play services are not installed, are outdated, or if the Play Store is missing or outdated. A device without an active Google account can also cause issues. Network errors or the inability to contact Google's servers can also prevent the verification from occurring.

On iOS, equivalent mechanisms detect jailbroken or modified environments, as well as integrity issues related to the Apple system. Again, if the device does not meet the authenticity criteria, the app may not function fully.

What to do?

This does not prevent you from using SwissTransfer: all features related to receiving and opening transfers remain accessible. Only the creation of a new transfer is blocked if the device does not pass the integrity check.

If you encounter this issue:

• Check that your phone has not been modified, that all system components are up to date, that you are connected to the Internet, and that your device has the required official services (Google Play Services for Android, up-to-date Apple system for iOS).

If necessary, you can always use SwissTransfer from a mobile browser or a computer via the website https://www.swisstransfer.com.

This guide details the measures implemented by Infomaniak to secure all your SwissTransfer data, whether it is personal (medical data, identification or login information) or even sensitive (financial information, trade secrets, intellectual property information, research and development, etc.).

Data Security and Privacy

The SwissTransfer infrastructure is based on cutting-edge technology, incorporating multiple levels of protection for your files:

1. During transfer: your files travel through an ultra-secure tunnel (AES-GCM encryption) that prevents any interception or modification during transmission.
2. Once stored: your data is "fortified" by double locking (LUKS and AES 256 bits). This security standard, more robust than the previous one, guarantees that even in the event of physical access to the server, your files remain completely unreadable.

Files are encrypted as soon as they arrive on Infomaniak's storage servers, and are processed exclusively in Infomaniak's data centers in Switzerland. These TIER III+ data centers ensure maximum availability: your files are always accessible and protected by multiple backup systems.

Files are automatically deleted after 15 days. An extension of up to 30 days is possible: it is offered by email to the sender on the 12th day, and remains available for 3 days.

Infomaniak continuously tests and audits the SwissTransfer infrastructure to identify and correct any vulnerabilities, thus ensuring constant protection against the latest cyberattacks.

Thank you for using Infomaniak to securely transmit your large documents to your contacts, thus guaranteeing a professional and efficient solution for your data exchanges.
