ZIIB provides a mobile app – PayWithCharlie, which can be downloaded to a smartphone via the Apple App Store or the Google Play Store.
ZIIB is the publisher of the PayWithCharlie app and it is responsible for the technology and app development. A contractual relationship when purchasing a good/service is established exclusively between the cardholder and the seller of the good/service.
The data are collected by the user who provides them. This could be data which are entered during the registration process. In addition, other data are automatically collected by ZIIB’s IT systems during the purchase process via the app. These are mainly technical data (e.g. payment type, vending machine or timestamp of the app call). These data are collected automatically as soon as the user initiates the purchase process. The data are collected and processed for the performance of the contract.
Personal data is any data with which you can be personally identified, such as name, title, address, email address, IP address, etc.
Personal data are only collected and used only after you have given your consent or the processing of the data is permitted by legal regulations.
The following regulations provide information on the type, scope and purpose of the collection and processing of personal data.
Relevant personal data (collectively referred to as “Data”) may include: Full name, date of birth, residential address, telephone and/or mobile phone number, email address. Encrypted account data, in particular password and security question with security response, technical data of the mobile device with which the PayWithCharlie App is used and which identifies this mobile device as uniquely as possible (“Device Data”). The device data include, in particular, device manufacturer, device type, device properties such as storage space or display resolution, IP address, mobile network operator, network information, operating system and version information and other information on the settings of the mobile device.
ZIIB collects, processes and uses personal data only to the extent that is necessary for the purchase process. This is done on the basis of Art. 6 para. 1 lit. b DSGVO, which permits the processing of data for the fulfilment of a contract or pre-contractual measures, as well as on the basis of Art. 6 para. 1 lit. c DSGVO, which makes processing necessary for the fulfilment of a legal obligation to which the controller is subject. We collect, process and use personal data about the use of our website (usage data) only to the extent that is necessary to enable the user to use the service or to charge for it.
The entity responsible for the user’s personal data is ZIIB Zahlungssysteme GmbH.
The data protection officer on site is:
The data protection officer can be contacted at the above address or by email at: email@example.com
When contacting ZIIB by e-mail, the user’s details are processed for the purpose of processing the contact request and its completion Art. 6 para. 1 lit. a DSGVO (consent of the data subject) and Art. 6 para. 1 lit. b DSGVO).
The user’s details may be stored in a ticket system or comparable request organization. The user has the right to receive information about the origin, recipient and purpose of your stored personal data free of charge at any time. The user also has the right to object, to data portability and the right to complain to the competent supervisory authority. Furthermore, the user may request the correction, deletion and, under certain circumstances, the restriction of the processing of his/her personal data. Personal data remains with ZIIB until the user requests deletion, revokes consent to storage or the purpose for storing the data no longer applies (e.g. after the request has been processed).
Mandatory legal regulations – in particular, retention periods under tax and commercial law – remain unaffected.
ZIIB reviews this necessity every two years.
If ZIIB has no legal basis for processing the personal data, it will be deleted. ZIIB only stores the collected personal data if there is a continuing business interest in doing so, in order to provide a service ordered by the user or to be able to fulfil statutory retention obligations, e.g. tax law or accounting obligations.
According to Art 6 (1) a) DSGVO, the consent of the user is required in order to process personal data. Any consent can be revoked by the user with effect for the future.
When processing personal data that is required to fulfil a contract with the user, Art. 6 (1) b) DSGVO is the corresponding legal basis. This also applies to processing operations that are already relevant pre-contractually.
Insofar as processing of personal data is necessary for compliance with a legal obligation of ZIIB, Art. 6 (1) c) DSGVO serves as the legal basis.
If the processing is necessary to protect a legitimate interest of ZIIB or a third party, Art. 6 (1) f) DSGVO serves as the legal basis for the processing, unless the legitimate interests of the user prevail.
The personal data collected, processed and stored by ZIIB are generally only stored for as long as the specific purpose of the storage requires. If the purpose of storage no longer applies, the data will be deleted or its processing restricted.
In addition, however, it may be that European regulations, applicable national laws or other regulations require longer storage of the data processed by ZIIB. If these storage periods expire, ZIIB will delete the data or restrict the processing thereof.
If the user deletes the PayWithCharlie app, the data will also be deleted completely.
Legal retention periods remain unaffected. These include the retention obligations under commercial and tax law: German Commercial Code (HGB), German Banking Act (KWG) and the Money Laundering Act (GwG). The periods specified there are two to ten years. If data are withheld as evidence, it is subject to the limitation periods of the German Civil Code (BGB) §§195ff and can last up to 30 years, with the regular limitation period being three years.
IP addresses are deleted after 90 days at the latest.

In addition, the user may revoke his consent at any time if we have collected and processed his personal data with his consent. The revocation of consent does not affect the legality of any processing carried out by ZIIB prior to the revocation, nor does it affect the legality of the processing of his personal data carried out on the basis of other lawful legal grounds.
The user also has the right to lodge a complaint with a supervisory authority regarding the collection and use of his/her personal data. The supervisory authority responsible for this is: Berlin Commissioner for Data Protection and Freedom of Information Friedrichstraße 219, 10969 Berlin

Apple/Google retains anonymized transaction data, including the approximate amount of the purchase, the name of the app developer and the app, the approximate date and time, and whether the transaction was completed successfully.
The transfer of your data to Apple/Google is based on Art. 6 (1) a DSGVO (consent) and Art. 6 (1) b DSGVO (processing for the performance of a contract). The user has the option to revoke his/her consent to data processing at any time. A revocation does not affect the validity of past data processing operations.

In order for PayWithCharlie to function properly, it is necessary to grant access to certain smartphone functions and personal data stored on the device. The user is requested once at the beginning or only when using the respective function to grant the appropriate access authorization.
Network Access & Network Connections Network access (via mobile data connection or WLAN network) is required as the PayWithCharlie app can only be used in online mode. This access is necessary for the functionality of the PayWithCharlie app and cannot be deactivated.
Receive data from the Internet (“receive data from Internet”). This authorization is necessary because the PayWithCharlie app is only functional when there is an existing connection to the internet. Offline operation of the PayWithCharlie app is not possible.
