1. Introduction

In the following, we provide information about the collection of personal data when using our mobile app (hereinafter only "App").

Personal data is any data that can be related to a specific natural person, such as their name or IP address.

1.1 Contact details

The controller within the meaning of Art. 4 (7) EU General Data Protection Regulation (GDPR) is FoodQuest GbR, Rheinsberger Straße 76/77, Berlin, Germany, email: [email protected]. We are legally represented by Daniel Bischoff, Teresa Sommer.

Our data protection officer can be reached via heyData GmbH, Schützenstraße 5, 10117 Berlin, www.heydata.eu , E-Mail: [email protected].

1.2 Scope of data processing, processing purposes and legal bases

We detail the scope of data processing, processing purposes and legal bases below. In principle, the following come into consideration as the legal basis for data processing:

  • Art. 6 para. 1 s. 1 it. a GDPR serves as our legal basis for processing operations for which we obtain consent.
  • Art. 6 para. 1 s. 1 lit. b GDPR is the legal basis insofar as the processing of personal data is necessary for the performance of a contract, e.g. if a user purchases a product from us or we perform a service for him. This legal basis also applies to processing that is necessary for pre-contractual measures, such as in the case of inquiries about our products or services.
  • Art. 6 para. 1 s. 1 lit. c GDPR applies if we fulfill a legal obligation by processing personal data, as may be the case, for example, in tax law.
  • Art. 6 para. 1 s. 1 lit. f GDPR serves as the legal basis when we can rely on legitimate interests to process personal data, e.g. for cookies that are necessary for the technical operation of our website.

1.3 Data processing outside the EEA

Insofar as we transfer data to service providers or other third parties outside the EEA, the security of the data during the transfer is guaranteed by adequacy decisions of the EU Commission, insofar as they exist (e.g. for Great Britain, Canada and Israel) (Art. 45 para. 3 GDPR).

In the case of data transfer to service providers in the USA, the legal basis for the data transfer is an adequacy decision of the EU Commission if the service provider has also certified itself under the EU US Data Privacy Framework.

In other cases (e.g. if no adequacy decision exists), the legal basis for the data transfer are usually, i.e. unless we indicate otherwise, standard contractual clauses. These are a set of rules adopted by the EU Commission and are part of the contract with the respective third party. According to Art. 46 para. 2 lit. b GDPR, they ensure the security of the data transfer. Many of the providers have given contractual guarantees that go beyond the standard contractual clauses to protect the data. These include, for example, guarantees regarding the encryption of data or regarding an obligation on the part of the third party to notify data subjects if law enforcement agencies wish to access the respective data.

1.4 Storage duration

Unless expressly stated in this privacy policy, the data stored by us will be deleted as soon as they are no longer required for their intended purpose and no legal obligations to retain data conflict with the deletion. If the data are not deleted because they are required for other and legally permissible purposes, their processing is restricted, i.e. the data are blocked and not processed for other purposes. This applies, for example, to data that must be retained for commercial or tax law reasons.

1.5 Rights of data subjects

Data subjects have the following rights against us with regard to their personal data:

  • Right of access,
  • Right to correction or deletion,
  • Right to limit processing,
  • Right to object to the processing,
  • Right to data transferability,
  • Right to revoke a given consent at any time.

Data subjects also have the right to complain to a data protection supervisory authority about the processing of their personal data. Contact details of the data protection supervisory authorities are available at https://www.bfdi.bund.de/EN/Service/Anschriften/Laender/Laender-node.html .

1.6 Obligation to provide data

Within the scope of the business or other relationship, customers, prospective customers or third parties need to provide us with personal data that is necessary for the establishment, execution and termination of a business or other relationship or that we are legally obliged to collect. Without this data, we will generally have to refuse to conclude the contract or to provide a service or will no longer be able to perform an existing contract or other relationship.

Mandatory data are marked as such.

1.7 No automatic decision making in individual cases

As a matter of principle, we do not use a fully automated decision-making process in accordance with article 22 GDPR to establish and implement the business or other relationship. Should we use these procedures in individual cases, we will inform of this separately if this is required by law.

1.8 Making contact

When contacting us, e.g. by e-mail or telephone, the data provided to us (e.g. names and e-mail addresses) will be stored by us in order to answer questions. The legal basis for the processing is our legitimate interest (Art. 6 para. 1 s. 1 lit. f GDPR) to answer inquiries directed to us. We delete the data accruing in this context after the storage is no longer necessary or restrict the processing if there are legal retention obligations.

2. Data processing in the app

2.7 Single sign-on

Users can log in to our app using one or more single sign-on methods. In doing so, they use the login data already created for a provider. The prerequisite is that the user is already registered with the respective provider. When a user logs in using a single sign-on procedure, we receive information from the provider that the user is logged in to the provider and the provider receives information that the user is using the single sign-on procedure in our app. Depending on the user's settings in his account on the provider's site, additional information may be provided to us by the provider. The legal basis for this processing is Art. 6 para. 1 sentence 1 lit. f GDPR. We have a legitimate interest in providing users with a simple log-in option.
