We shall modify the privacy policy as soon as this is made necessary due to amendments to our data processing. We shall inform you as soon as you are required to make a commitment (e.g.: consent) or some other individual notification is required due to the amendments.

#Security measures

  1. Pursuant to Art. 32 GDPR, taking into account the state of the art, the costs of implementation and the nature, scope, context and purposes of processing as well as the risk of varying likelihood and severity for the rights and freedoms of natural persons, we shall implement appropriate technical and organizational measures to ensure a level of security appropriate to the risk; these measures shall include, in particular, guaranteeing the confidentiality, integrity and availability of data by controlling physical access to the data, as well as controlling access, entry and sharing of this data, and securing its availability and removal. In addition, we have implemented processes that guarantee the safeguarding of the rights of persons affected, the deletion of data and a reaction to threats to data. Furthermore, we already take the protection of personal data into consideration at the development stage, i.e.: in our selection of hardware, software and processes, in accordance with the principle of data protection by design and by default (Art. 25 GDPR).
  2. These security measures include, in particular, encrypted transmission of data between your browser and our sever.

#Cooperation with processors and third parties

  1. If we disclose or transfer data to other persons and companies (processors or third parties), or allow them access to this data, this is only done on the basis of a legal authorization. For example: if a transfer of data to third parties, such as a payment service provider, in accordance with Art. 6 (1) b GDPR, is required to fulfill a contractual agreement; if you have provided your consent; if there is a legal obligation to do so; or on the basis of our legitimate interests (e.g.: when using the services of a contractor, a web host, etc.).
  2. If we contract third parties to process data on the basis of a so-called “processing contract”, this shall be performed on the basis of Art. 28 GDPR.

Transfers to a third country

  1. If we process data in a third country (i.e.: outside of the European Union (EU) or the European Economic Area (EEA) or if this is done through the contracting of services by third parties, or if data is disclosed or transferred to third parties, this only occurs if it is for the purposes of fulfilling our (pre)contractual commitments, on the basis of your consent, due to a legal obligation or on the basis of our legitimate interests. Subject to statutory or contractual authorization, we will only process or have data processed in a third country if the specific provisions pursuant to Art. 44 et seq. GDPR have been met. In other words, the processing is done, for example, on the basis of special guarantees or by complying with officially approved special contractual obligations (so-called “standard contractual clauses”).

Rights of the data subjects

  1. You have the right to obtain confirmation as to whether or not data concerning you are being processed, and to request information on this data, as well as additional information and a copy of the data pursuant to Art. 15 GDPR.
  2. Pursuant to Art. 16 GDPR, you have the right to request the completion of data concerning you or the rectification of inaccurate personal data concerning you.
  3. Pursuant to Art. 17 GDPR, you have the right to obtain the erasure of personal data concerning you without undue delay, or, pursuant to Art. 18 GDPR, the right to obtain restriction of processing of your data.
  4. You have the right to receive personal data concerning you and which you have provided to us, pursuant to Art. 20 GDPR, and to transmit those data to another controller.
  5. Furthermore, in accordance with Art. 77 GDPR, you have the right to lodge a complaint with the competent supervisory authority.

Right of revocation

You have the right to withdraw your consent with future effect, in accordance with Art. 7 (3) GDPR.

Right to object

  1. You have the right to object to the future processing of your data pursuant to Art. 21 GDPR. This objection can be raised in particular against processing of data for direct marketing purposes.

Cookies and the right to object direct marketing

  1. We use temporary and permanent cookies, which are small files that are stored on users’ devices (for an explanation of the term and of how cookies work, see the last section of this privacy policy). In part, these cookies are required to secure or operate our online offerings (e.g.: to display the website) or to save users’ decisions when they give consent to the use of cookies via the cookie banner. In addition, we or our technology partners set cookies for the purposes of media measurement and marketing, of which the users are informed through the privacy policy.
  2. You can choose to opt-out of the use of cookies put in place for the purposes of online marketing; this is explained through a multitude of services, particularly in case of tracking, on the American website http://www.aboutads.info/choices/ or the EU website http://www.youronlinechoices.com/. Furthermore, the storing of cookies can be switched off by changing your browser settings. Please note that this may mean that you may not be able to use all the features of our online offering.

Erasure of data

  1. Data processed by us are deleted or the processing thereof is restricted pursuant to Art. 17 and 18 GDPR. Unless expressly indicated under this privacy policy, data that we save is deleted as soon as it is no longer required for the intended purpose and the deletion thereof is not contrary to any legal duty to keep and retain these data. If these data are not deleted because they are required for other legally permitted purposes, the processing thereof shall be restricted. In other words, these data will be locked and not processed for other purposes. For example, this applies to data that must be kept for accounting or taxation reasons.
  2. In accordance with statutory requirements, data is kept for 6 years in accordance with Art. 257 (1) Commercial Code (trading books, inventory, opening balance sheets, year-end reports, business correspondence, accounting records, etc.) and for 10 years in accordance with Art. 147 (1) German Fiscal Code (accounts, records, status reports, accounting records, trade and business correspondence, documents needed for tax purposes, etc.).

Provision of contract-related services

  1. We process user data (e.g.: names, addresses and user contact information), contract-related data (e.g.: services that have been engaged in, names of contact persons, payment information) for the purposes of meeting our contractual obligations and services pursuant to Art. 6 (1) b GDPR. Those entries marked as mandatory on online forms are required in order to close a contract.
  2. Users can create a user account which allows them to view their settings or process their contents (such as components, rations, texts). Users are informed of which information is mandatory during the registration process. User accounts are not publicly accessible and cannot be indexed by search engines. If users cancel their account, the data pertaining to the user account is deleted, provided it does not have to be saved for accounting or taxation reasons as per Art. 6 (1) c GDPR. It is the responsibility of the user to save their data prior to the end of the contract when cancelling their account. We reserve the right to irrevocably delete all data saved over the duration of the contract.
  3. During registration and when logging in, as well as when our online services are being used, we save the IP address and the time of access of the respective user activity. We save this information on the basis of our legitimate interests and those of the user in order to protect the user from abuse and other unauthorized use. As a rule, this data is not transferred to third parties, unless required to pursue our claims or if there is a legal obligation to do so in accordance with Art. 6 (1) c GDPR.
  4. We process usage data (e.g.: which pages related to our online offering a user has visited, interest in our products) and content-related data (e.g.: entries in the contact form or the user profile) for advertising purposes within a user profile, i.e.: in order to display product information to a user based on services the user has already used.
  5. Deletion occurs once legal warranty obligations and similar obligations have ended. The necessity of storing this data is verified every three years; in cases where there is a legal obligation to store data, data is deleted on termination (end of the legal obligation to keep accounting-related data: 6 years; end of the legal obligation to keep taxation-related data: 10 years); information in a customer account is kept until it has been deleted.
  6. Backups are to be kept for as short a period as possible. However, with respect to the use of software, particularly newly developed software subject to constant upgrades, it may be necessary to retroactively eliminate inconsistencies and to thereby also protect the integrity of user data. It can therefore take up to 30 days to fully deactivate a user account and delete this data from the backup files following account cancellation. Data will continue to be saved beyond this period if required for billing purposes or to serve legitimate contractual interests, which override the data subject’s interests in deleting this data (e.g.: blocking an e-mail address if a user has been banned from the website) or due to regulatory provisions.

Visibility of profiles and portions of contents

  1. User profiles within our applications cannot be viewed by other users.
  2. However, users can choose to share their data contents (e.g.: information on the fodder rations in Dairy Ration) with other users or make this content public based on the options specified in the application.
  3. We inform the user that information that is shared with other users can be linked to the user. Links depend on the information that a user shares and provides, e.g.: if personal information or an e-mail address is included when sharing this data. In addition, we indicate that some information cannot be retracted, for example, if this is shared via other platforms or is acknowledged by a third party.

Contacting us

  1. When contacting us (using our contact form or via e-mail), user data is processed to process and handle the contact request, in accordance with Art. 6 (1) b GDPR.
  2. User data can be saved to our Customer Relationship Management System (CRM System) or a similar organization that fields inquiries.
  3. We delete the inquiries once they are no longer required. We verify the necessity every two years; we permanently save inquiries from customers having an account and refer to the data in the customer account for deletion purposes. If there is a legal obligation to retain data, data is deleted on termination (end of the legal obligation to keep accounting-related data: 6 years; end of the legal obligation to keep taxation-related data: 10 years).

Saving access data and log files

  1. On the basis of our legitimate interests, pursuant to Art. 6 (1) f GDPR, we save data each time the server on which this service is located (so-called server log files) is accessed. This access data includes the name of the website accessed, the file, date and time it was accessed, the amount of data transferred, notifications regarding a successful retrieval, browser type and version, the user’s operating system, referrer URL (the previously visited site), IP address and the provider through which it was accessed.
  2. For security reasons (e.g.: to resolve abuse or fraud), log file information is saved for a maximum of seven days, after which it is deleted. Data that must be saved longer for evidentiary purposes are exempt from deletion and are saved until the respective incident has been resolved.

Cookies & media measurement

  1. Cookies contain information that is transferred from our web server or third-party web servers to the users’ web browser, where they are saved for future access. Cookies are small files or other packets of data.
  2. We use “session cookies”, which are only saved while a user is accessing our online presence (e.g.: to save your login status or to make it possible to use the shopping cart function, thereby making it possible to use our online offering). A unique, randomly generated identification number is saved to a session cookie, a so-called session ID. A cookie also contains information about its source and the storage period. These cookies cannot save any other data. Session cookies are deleted when you have finished using our online offering and you have, for example, logged out.
  3. If we use cookies to carry out randomized pseudonymized media measurement we inform the user separately in this privacy policy or when obtaining consent.
  4. If users do not want to have cookies saved to their device, they are asked to deactivate the respective option in their browser settings. Saved cookies can be deleted by changing browser settings. Excluding cookies can limit the functionality of this online offering.

Google Sign-In

  1. As a part of our online offerings, on the basis of our legitimate interests, we use the Google Sign-In service offered by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. The legal basis is Art. 6 (1) f GDPR.

  2. Standard contractual clauses of Google: https://cloud.google.com/terms/data-processing-terms.

  3. The user can use Google Sign-In to register for our service. To register, the user is transferred to the Google page, where s/he can register using her/his Google access data. This links the user’s Google profile to our service. This transfers the public data from the user’s Google profile and the user’s e-mail address and profile URL to us. Of this data, we only use the name, e-mail address and the user’s Google ID. This information is required to close the contract, in order to be able to identify the user. When you register for our service using Google Sign-In, you agree to having this data transferred to us. Every time someone registers via Google Sign-In, we inform Google that this user is using our service. The user can delete the link from our service to Google via https://myaccount.google.com/permissions.

  4. Additional information and Google’s privacy policy can be accessed via https://policies.google.com/privacy.

Use of mobile apps, use of Google Firebase

  1. If you install our mobile apps through the iTunes store or Google Play, some of your data will be transferred to the store operators: User name, e-mail address, download time, individual device identifiers. We have no influence over the saving of this data and cannot be held liable. We use this data to install the app on your device.

  2. Our apps use the Google Firebase platform under Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA to save and manage data, prepare contents, and for the purposes of user account management.

GDPR) we can use Google Firebase Analytics. Additional information and Google’s privacy policy can be accessed via https://policies.google.com/privacy.

  5. You can opt out of the use of Firebase Analytics through your app settings.

Integration of services and third-party content

  1. Within our online offering, on the basis of our legitimate interests (i.e.: our interests in the analysis, optimization and profitable operation of our online offering pursuant to Art. 6 (1) f. GDPR) we make use third party content or service offerings, in order to integrate their contents and services, such as videos or fonts (hereinafter collectively referred to as “contents”). This always presumes that the third-party providers of this content perceive the users’ IP addresses, since, without the IP address, they would not be able to send the content to the user’s browser. The IP address is thereby required to display content. We strive to only use content whose respective providers exclusively use IP addresses for delivering content. In addition, third party providers can use so-called pixel tags (invisible graphics, also known as web beacons) for statistical or marketing purposes. The pixel tags can be used to evaluate information such as user traffic to the pages on these websites. Furthermore, pseudonymized information can be saved to cookies on the user’s device and contain technical information such as the browser and the operation system, linked websites, access time and other information on the use of our online offering, and also link to information such as this from other sources.
  2. The following graphic is an overview of the third-party providers as well as their contents, in addition to links to their privacy policies, which contain further information on how they process data and, as already mentioned here, their opt-out settings:
