How we work

Learn more about
our Tech-Stack and Tooling

Project Management

Our project and requirements management combines techniques from the agile and classical worlds, most of our PMs are IPMA certified and we are used to working according to KANBAN and SCRUM. Atlassian tools such as Confluence, Jira and Jira Service Management are well established.

Frontend Development

The Tech-Stack of our Frontend Developers:
TypeScript, Vue 3, Vite, Nuxt 3, Tailwind CSS and Pinia.
What's really handy is that both our frontend and backend teams work with TypeScript. This also allows the teams to work cross-functionally and there is no need for ‘translation’.

Backend Development

The Backend team is currently writing Serverless Functions in the Google Cloud using TypeScript and NestJS.
Our loyalty system is build with Java, Spring, Hibernate and querydsl.


We are managing our IT infrastructure using Infrastructure as a Code (IaC) with Terraform for AWS and Google Cloud. So we don't have to worry about manually setting up servers, but we do have a high-performance and scalable infrastructure at low cost. This gives us more time for what we really like to do: building awesome applications.


As a base for our projects we use self-developed product solutions, including a loyalty engine, a headless CMS, our own app framework and a development kit for serverless functions in the GCP.

Quality Assurance

Our quality assurance process consists of automated tests as part of the software development process and structured functional tests planned and executed by our test team. Continuous improvement is based on DIN 9001.

Privacy Policy

We are very delighted that you have shown interest in our enterprise. Data protection is of a particularly high priority for the management of the Leanera GmbH. The use of the Internet pages of the Leanera GmbH is possible without any indication of personal data; however, if a data subject wants to use special enterprise services via our website, processing of personal data could become necessary. If the processing of personal data is necessary and there is no statutory basis for such processing, we generally obtain consent from the data subject.

The processing of personal data, such as the name, address, e-mail address, or telephone number of a data subject shall always be in line with the General Data Protection Regulation (GDPR), and in accordance with the country-specific data protection regulations applicable to the Leanera GmbH. By means of this data protection declaration, our enterprise would like to inform the general public of the nature, scope, and purpose of the personal data we collect, use and process. Furthermore, data subjects are informed, by means of this data protection declaration, of the rights to which they are entitled.

As the controller, the Leanera GmbH has implemented numerous technical and organizational measures to ensure the most complete protection of personal data processed through this website. However, Internet-based data transmissions may in principle have security gaps, so absolute protection may not be guaranteed. For this reason, every data subject is free to transfer personal data to us via alternative means, e.g. by telephone.

1. Definitions

The data protection declaration of the Leanera GmbH is based on the terms used by the European legislator for the adoption of the General Data Protection Regulation (GDPR). Our data protection declaration should be legible and understandable for the general public, as well as our customers and business partners. To ensure this, we would like to first explain the terminology used.

In this data protection declaration, we use, inter alia, the following terms:

2. Name and Address of the controller

Controller for the purposes of the General Data Protection Regulation (GDPR), other data protection laws applicable in Member states of the European Union and other provisions related to data protection is:

Leanera GmbH

Nikolaistraße 12-14

04109 Leipzig

3. Collection of general data and information

The website of the Leanera GmbH collects a series of general data and information when a data subject or automated system calls up the website. This general data and information are stored in the server log files. Collected may be (1) the browser types and versions used, (2) the operating system used by the accessing system, (3) the website from which an accessing system reaches our website (so-called referrers), (4) the sub-websites, (5) the date and time of access to the Internet site, (6) an Internet protocol address (IP address), (7) the Internet service provider of the accessing system, and (8) any other similar data and information that may be used in the event of attacks on our information technology systems.

When using these general data and information, the Leanera GmbH does not draw any conclusions about the data subject. Rather, this information is needed to (1) deliver the content of our website correctly, (2) optimize the content of our website as well as its advertisement, (3) ensure the long-term viability of our information technology systems and website technology, and (4) provide law enforcement authorities with the information necessary for criminal prosecution in case of a cyber-attack. Therefore, the Leanera GmbH analyzes anonymously collected data and information statistically, with the aim of increasing the data protection and data security of our enterprise, and to ensure an optimal level of protection for the personal data we process. The anonymous data of the server log files are stored separately from all personal data provided by a data subject.

4. Routine erasure and blocking of personal data

The data controller shall process and store the personal data of the data subject only for the period necessary to achieve the purpose of storage, or as far as this is granted by the European legislator or other legislators in laws or regulations to which the controller is subject to.

If the storage purpose is not applicable, or if a storage period prescribed by the European legislator or another competent legislator expires, the personal data are routinely blocked or erased in accordance with legal requirements.

5. Rights of the data subject

6. Legal basis for the processing

Art. 6(1) lit. a GDPR serves as the legal basis for processing operations for which we obtain consent for a specific processing purpose. If the processing of personal data is necessary for the performance of a contract to which the data subject is party, as is the case, for example, when processing operations are necessary for the supply of goods or to provide any other service, the processing is based on Article 6(1) lit. b GDPR. The same applies to such processing operations which are necessary for carrying out pre-contractual measures, for example in the case of inquiries concerning our products or services. Is our company subject to a legal obligation by which processing of personal data is required, such as for the fulfillment of tax obligations, the processing is based on Art. 6(1) lit. c GDPR. In rare cases, the processing of personal data may be necessary to protect the vital interests of the data subject or of another natural person. This would be the case, for example, if a visitor were injured in our company and his name, age, health insurance data or other vital information would have to be passed on to a doctor, hospital or other third party. Then the processing would be based on Art. 6(1) lit. d GDPR. Finally, processing operations could be based on Article 6(1) lit. f GDPR. This legal basis is used for processing operations which are not covered by any of the abovementioned legal grounds, if processing is necessary for the purposes of the legitimate interests pursued by our company or by a third party, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subject which require protection of personal data. Such processing operations are particularly permissible because they have been specifically mentioned by the European legislator. He considered that a legitimate interest could be assumed if the data subject is a client of the controller (Recital 47 Sentence 2 GDPR).

7. The legitimate interests pursued by the controller or by a third party

Where the processing of personal data is based on Article 6(1) lit. f GDPR our legitimate interest is to carry out our business in favor of the well-being of all our employees and the shareholders.

8. Period for which the personal data will be stored

The criteria used to determine the period of storage of personal data is the respective statutory retention period. After expiration of that period, the corresponding data is routinely deleted, as long as it is no longer necessary for the fulfillment of the contract or the initiation of a contract.

9. Provision of personal data as statutory or contractual requirement; Requirement necessary to enter into a contract; Obligation of the data subject to provide the personal data; possible consequences of failure to provide such data

We clarify that the provision of personal data is partly required by law (e.g. tax regulations) or can also result from contractual provisions (e.g. information on the contractual partner). Sometimes it may be necessary to conclude a contract that the data subject provides us with personal data, which must subsequently be processed by us. The data subject is, for example, obliged to provide us with personal data when our company signs a contract with him or her. The non-provision of the personal data would have the consequence that the contract with the data subject could not be concluded. Before personal data is provided by the data subject, the data subject must contact any employee. The employee clarifies to the data subject whether the provision of the personal data is required by law or contract or is necessary for the conclusion of the contract, whether there is an obligation to provide the personal data and the consequences of non-provision of the personal data.

10. Existence of automated decision-making

As a responsible company, we do not use automatic decision-making or profiling.
