3. Registration data and server logs
3.1 Scope and purpose of the processing of personal data
We only process our users' personal data to the extent necessary for the use of the app. An individual user account is required to access Ello. In addition, your age is required to ensure that all users are of legal age. Your intentions, motivation, and gender are processed in order to offer you an even more personalised product. When using the app, technical connection data transmitted to us from your device is also processed. In this context, we process registration data and the following personal data:
Registration data
- User name
- Email address
- Age
Optional
- 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 your age. When registering for our app, you have the option of entering your data anonymously using a pseudonym and an email address that does not contain any personal identification information. 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
Server logs are processed within the scope of our legitimate interest pursuant to Article 6(1)(f) GDPR for the provision of our app, to secure our systems and to ensure technical functionality. Provision is technically necessary so that the content you request can be delivered to you. The processing of your registration 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, you will not be able to use the app. You can revoke your consent to the processing of personal data at any time. To do so, please contact our data protection officer (see point 2). Revocation means that you will no longer be able to use the app. Please note that revocation only applies to the future. Processing that took place before revocation is not affected.
3.3 Transfer of personal data and recipients
No data is transferred to countries outside the European Economic Area. We use the AWS European sovereign cloud to provide our services, where 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 we receive your revocation.
