3. Registration data and server logs

3.1 Scope and purpose of the processing of personal data

We only process personal data of our users to the extent necessary for the use of the app. To gain access to Ello, an individual user account is required. In addition, your age is required to ensure that all users are of legal age. Your intentions, motivation and gender are processed to offer you a more personalised product. When using the app, technical connection data is also processed, which is transmitted to us by your device. As part of this, we process registration and the following personal data: 

Registration data 

  • user name
  • e-mail address
  • age 

Optionally also 

  • gender
  • user intention and motivation 

Server logs 

  • IP address
  • language setting
  • time zone
  • user ID 

We respect your privacy and would like to point out that it is not necessary to provide personal data when registering - with the exception of age. When registering for our app, you have the option of entering your data anonymously using an alias as well as use an e-mail address that does not include personal identifiable data. This means that you can register with a user name that does not allow any direct personal reference. We require your age to ensure that you are of legal age.

3.2 Legal basis for data processing

The processing of server logs is carried out within the scope of our legitimate interest pursuant to Article 6(1)(f) GDPR to provide our app, to secure our systems and to ensure technical operability. The provision of the data is technically necessary so that the retrieved content can be delivered to you. The processing of your personal data within the app is based on your consent in accordance with Article 6(1)(a) GDPR. If you do not give us your consent, it is not possible to use the app. You can withdraw your consent to the processing of personal data at any time. To do so, please contact our data protection officer (see point 2). If you withdraw your consent, you will no longer be able to use the app. Please note that the revocation is only effective for the future. Processing that took place before the revocation is not affected.  

3.3 Transfer of personal data and recipients

In principle, data is not passed on to other third parties. However, relevant data may be passed on to the law enforcement authorities in the event of an attack on our systems. No data is transferred to countries outside the European Economic Area. To provide our service, we use the AWS european sovereign cloud, in which your data is stored. The operator is Amazon Web Services EMEA SARL (38 Avenue John F. Kennedy, L-1855 Luxembourg). The data is only processed in the AWS Paris region.

3.4 Storage period

Your registration data will be stored until the reception of your revocation. The server logs are stored for as long as it is technically necessary. If the server logs are no longer technically necessary, they are anonymised. In the event of criminal proceedings, the data will be deleted once the proceedings have been concluded.

4.1 Scope and purpose of the processing of personal data

The respective chat histories are processed in order to make the use of the AI-based chatbot available and to anonymise the data. Personal data is processed as part of the use of Ello. The personal data that is processed is the data that you provide within the chatbot itself.

In principle, data is not passed on to other third parties. However, relevant data may be passed on to the law enforcement authorities in the event of an attack on our systems. In principle, no data is transferred to countries outside the European Economic Area. However, it cannot be ruled out that, in the event of misuse, Microsoft employees based outside the EU may gain access for verification purposes. To provide our service, we use the AWS european sovereign cloud, in which your data is stored. The operator is Amazon Web Services EMEA SARL (38 Avenue John F. Kennedy, L-1855 Luxembourg). The data is only processed in the AWS Paris region. In order to be able to offer the AI-based chatbot, HelloBetter uses the cross-regional version (Europe) of Azure OpenAI Endpoint (Microsoft Corporation, One Microsoft Way, Redmond, Washington, 98052-6399, USA). Microsoft stores your data only in the event that the abuse monitoring system detects something in the chat that is judged to be potential abuse. The data is then checked by a human. The verifiers are authorised Microsoft employees who access the data via selective queries using request IDs, Secure Access Workstations (SAWs) and Just-in-Time (JIT) request approvals by team leaders.
