If data must be retained for evidentiary reasons, it is exempt from deletion until the incident has been finally clarified.

The legal basis for this data processing is our legitimate interests (Art. 6 para. 1 p. 1 lit. f DSGVO) in providing a functioning website.

When you use the cofenster app, your IP address, the date and time of the request, your http status code, the amount of data and information about your operating system are recorded by default. We need this data to ensure the operation of our app.

This data processing is based on our legitimate interests (Art. 6 para. 1 p. 1 lit. f DSGVO) in providing a functioning mobile app.

2.3 Appointment

Through our website you can make an appointment with us to discuss the offer that suits you. You will be shown a calendar function, for which you only need to select the appointment that suits you and enter an e-mail address.

This type of data processing takes place, insofar as a natural person is to become our contractual partner, for the purpose of initiating a contract (Art. 6 para. 1 p. 1 lit. b DSGVO). Otherwise, we process this data on the basis of our legitimate interest (Art. 6 para. 1 p. 1 lit. f DSGVO) in presenting our services to our future customers and, if necessary, providing assistance.

The service provider used for this purpose, who will only act in accordance with our instructions, is described in more detail in section 3.3.

2.4. Entering into, executing and managing the contracts concluded with us and invoicing our services

When concluding a contract with us, we collect and store the name and address of our customers as well as the name and email address of a contact person. The email address also functions as the login name for the application on the website. You will also be required to enter a password.

We also process the payment data of our customers for the monthly billing of our services. Depending on the payment method, we process your name, bank code and account number or your credit card number. This also requires details of the contract concluded and the amount owed. We use a service provider for the technical facilitation of the payment (see also section 3.1).

We also use a third-party provider to manage the individual subscriptions and in particular for invoicing (see section 3.2). This data processing is carried out for the execution of the contract and billing of our services.

We store your contact details (such as name, address, e-mail and telephone, if applicable) in our customer database. For this purpose, we use the service provider mentioned in section 3.3, who will only act according to our instructions.

Part of our contractual service is also the temporary hosting of the created content. This requires the storage of the video including the respective content. We also use third-party providers for this, who only act on our behalf (see section 3.4).

The legal basis for the aforementioned data processing is the fulfilment of the contract concluded with us (Art. 6 para. 1 lit. b DSGVO) or, if our contractual partner is not a natural person, our legitimate interests in enabling the performance of the contracts concluded with us (including payment) (Art. 6 para. 1 sentence 1 lit. f DSGVO).

2.5 Use of your data for advertising purposes

We use your contact details such as address, e-mail or telephone numbers to contact you for advertising purposes.

This is done partly on the basis of our legitimate advertising interests (Art. 6 para. 1 lit. f DSGVO) or, insofar as we contact you by e-mail or telephone, on the basis of your consent (Art. 6 para. 1 lit. a DSGVO).

2.6 Website analysis

We have your user behaviour analysed by third-party providers (see section 3.4 on providers) and thus obtain valuable analyses that help us to design and improve our services.

We only carry out such an evaluation with your express consent (Art. 6 para. 1 p. 1 lit. a DSGVO). If you do not give your consent, your user behaviour will not be evaluated by the third-party provider and we will not be able to improve our services accordingly.

3. Do we share your data and is it processed in third countries?

We use the services of Hubspot, 2nd Floor 30 North Wall Quay, Dublin 1, Ireland to manage our customer contact.

If you would like to make an appointment with us via our site and provide your contact details (name and email) as well as the desired time of a meeting, this data will be stored and processed by Hubspot.

Hubspot also supports us with the management of customer contacts and creates an online marketing concept for us to improve the business relationship. For this purpose, Hubspot receives your contact data (name, telephone and email) as well as information about the customer contact (details of the last contact), whether a contract was concluded and when this was the case.

Hubspot only processes your data according to our instructions. Hubspot also partially processes your data in the USA.

In addition, we encrypt the data transferred to Hubspot in-transit to ensure the security of the data. Details on data processing by Hubspot can be found on the Hubspot website.

3.2 Video Hosting

If you have created a video in the cowindow app, it will not be stored locally but with a third-party provider. This is Amazon Web Services EMEA SARL (hereinafter referred to as "AWS") at 38 Avenue John F. Kennedy, L-1855, Luxembourg. AWS only processes your data on our behalf (Art. 28 DSGVO). AWS receives all the video material recorded and stored by you via a connection in the mobile app and then makes it available on demand via the web app. The transmission of the IP address is also necessary for this.

In some cases, server maintenance by a US Amazon company may be necessary. We have therefore concluded the standard contractual clauses issued by the EU Commission with Amazon for data transfer to the USA ( In addition, we encrypt the data transferred to Amazon in-transit to ensure the security of the data.
