All you need to register for an account is the following:

• Your email address
• A password which you choose
• Your phone number for two-factor authentication

Note: We only store your email address and your phone number. The password you chose isn't stored by us but is stored encrypted on your device.

Important: We ask for your mobile number to send you a code and confirm it’s really you signing in. This is called two-factor authentication and protects your data.
We never call you or share your number with anyone.

Nobody except you can access your personal information because we always store your data encrypted. When your data is shared with researchers, it’s pseudonymized first.

Related topics

See What is pseudonymization?

We store your data and documents exclusively on servers within Germany and always encrypted. Only you have access to the content of your data.

Data4Life is certified by the German Federal Office for Information Security (BSI) as ISO 27001-compliant on the basis of “IT-Grundschutz”.

Besides many other measures to protect your privacy, we use end-to-end encryption (E2EE) for all health data.

End-to-end encryption ensures that only you can access the content of the encrypted data. Even Data4Life cannot understand the encrypted data since we don’t have access to the cryptographic keys needed to decrypt the data. This means that we never have access to the content.

Personal data is encrypted on your personal device – mobile device or desktop computer – and can only be decrypted by you. You’re in control and can decide if you want to explicitly grant access, for example, to your doctor.

Pseudonymization is a method to alter data so that it can’t be linked to you without the use of additional information.

Before we share your data with researchers, we replace identifying information, such as your name, email address, and phone number, with a unique random number (the pseudonym). This way, your data helps research while your identity is protected.

To help protect your data privacy, the app uses two-factor authentication (2FA), also called 2-step verification.
Two-factor authentication is a process where during sign-in, we ask you for an additional form of identification.

This second factor of authentication increases security because an attacker would need access to your phone, as well as your email address and password, to access your account.

Two-factor authentication uses the following:

• Something you know: your password
• Something you have: your phone or tablet

Note: Two-factor authentication is always active and can't be switched off.

When you log in, the app asks you for the following:

• Your email address and password
• The verification code that we send to your phone by SMS

Two-factor authentication is the reason why we ask for your phone number when you create your user account. If we can send verification codes to your personal phone by SMS, that's another layer of security for your account and your data.

To help protect your health data, create a complex password for your user account. You should always use different passwords for your important accounts, like email, online banking, social media, and health information.

Your password for the app must meet the following requirements:

• 8 characters or more
• At least 1 numeric character (0-9)
• At least 1 special character (! " # $ % ' ( ) * + , - . / : ; < = > ? @ [ \ ] ^ _ ` { | } ~)
• Mix of uppercase and lowercase letters (A-Z, a-z)

Tip: The best passwords are randomly generated ones like x7fbjsBAEZyF@,Z$. To create random passwords, you can use password managers.

Password managers can do the following for you:

• Create strong passwords
• Store passwords
• Autofill passwords when you log in to websites and web apps

To help you protect your user account and your data privacy, the app runs a password check when you create your user account. The check is an extra step after ensuring that your password meets our complexity requirements.

Important: The password check can detect if your password was compromised in a previous data leak on the internet. Such compromised passwords are considered unsafe and should be changed.

The recovery key is a personal code that helps to protect your user account. If you ever forget your password or want to change it, you need your recovery key.

The key is like a backup password, similar to the personal unlocking key (PUK) of your mobile phone.

The recovery key consists of 16 blocks of numbers and letters:

33ef 3c1d d4e6 8694 0820 9f1f 1468 32ae

1109 cc5d 4b99 90b7 048d 8ab1 808c 6c7b

Creating a recovery key is an optional step when you create your user account. It's highly recommended as the key ensures access to your user account.
Store your recovery key in a safe and private place that you can access without a computer.

Important: If you don’t have a recovery key, and you forget your password, you permanently lose access to your account and your data.

We can’t help you reset your password without your recovery key because we use end-to-end encryption to keep your account protected and private.

• When you copy and paste your recovery key from the PDF file – When you copy and paste your recovery key from your saved PDF file, unwanted double spaces can be inserted. After you paste your recovery key, verify that there’s exactly 1 space between blocks.

• Maybe you have more than one recovery keys – If you had issues when you created your user account, you might have created 2 or more recovery keys in 2 or more PDF files. The files are stored together on your device. If you have several recovery key PDF files, enter the recovery keys to find the correct one.
