Disclaimer
The contents of this app are created with due care. However, the provider does not guarantee the accuracy, completeness, and up-to-date nature of the provided contents. The use of the app’s contents is at the user’s own risk. Simply using the app does not establish any contractual relationship between the user and the provider.
§ 2 External Links and Third-Party Content
This app contains links to third-party websites (“external links”). These websites are subject to the liability of their respective operators. Upon initially linking to the external links, the provider checked the third-party content for any potential legal violations. At that time, no violations were apparent. The provider has no influence over the current and future design or content of the linked pages. Setting external links does not imply that the provider endorses the content behind the link. Continuous monitoring of external links is not feasible for the provider without specific indications of legal violations. However, if violations are known, such external links will be removed immediately.
Privacy policy
The Waste Calendar App is an app that can display collection dates of the municipal waste collection service and dates for waste types that are not disposed of via the regular waste collection, sorted by street and in various views. The Municipality of Hiddenhausen also offers you a simplified way of getting in contact through the app.
Within the app, it is necessary to process personal data. The protection of your personal data is a top priority for the Municipality of Hiddenhausen. For this purpose, the Municipality of Hiddenhausen works closely with the manufacturer of the app, Chrobyte GmbH.
Chrobyte is the company that developed the app and provides the technical infrastructure.
The data processing body and controller within the meaning of the General Data Protection Regulation (GDPR) is the Municipality of Hiddenhausen.
Processing of Personal Data
Personal data is any information relating to an identified or identifiable natural person. An identifiable person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name. Your data is transmitted securely using state-of-the-art encryption.
The app collects and processes the following categories of personal data:
- Master data of employees (name, telephone number, email address, fax number and room number),
- Master data of users (first name, last name and email address),
- Communication data (app version, operating system, device name (e.g. iPhone 11, Samsung Galaxy S8 etc.), date and time of the session, country/language, provider name (e.g. Telekom, Vodafone etc.)).
Personal data is processed on the basis of Art. 6(1)(e) of the General Data Protection Regulation (GDPR) in conjunction with § 3(1) of the Data Protection Act of North Rhine-Westphalia (DSG NRW). The necessary personal data is transferred to the manufacturer of the app by the Municipality of Hiddenhausen pursuant to Art. 6(1)(e) GDPR in conjunction with § 8(2) No. 1 DSG NRW, and by the user pursuant to Art. 6(1)(a) GDPR (consent given within the contact form).
Logging
The use of the app is logged. The stored data serves internal system-related and statistical purposes. The following information is logged: name of the retrieved data, date and time of retrieval, amount of data transferred, status message of the retrieval, app version, device type and operating system. In addition, the IP addresses and providers of the requesting devices are included in the logs.
For security reasons, each installation of the app registers with the server on first launch using a randomly generated identification key and is assigned a unique client ID. For authorized communication with the server, the server issues signed web tokens to the client, each valid for one hour. To analyze and determine the number of users, the operating system, device type and app version in use are stored together with the issued web token and client.
Disclosure of Data to Third Parties
Personal data is collected and transferred to state institutions and authorities entitled to receive information only within the scope of the applicable laws or where we are obliged to do so by court order. All employees and service providers have been obliged by us to maintain confidentiality and to comply with data protection regulations.
External Links
This app contains references (links) to websites maintained by third parties.
The Municipality of Hiddenhausen has no control whatsoever over the content of third-party websites. The respective provider or operator of the linked pages is always responsible for their content. The linked pages were checked for possible legal violations at the time of linking. No unlawful content was apparent at the time of linking. The information, goods or services offered there are neither checked nor supported in any way by the Municipality of Hiddenhausen. Should we become aware of any legal violations, we will remove such links immediately.
The Municipality of Hiddenhausen therefore accepts no responsibility whatsoever, on whatever legal grounds, for the content of third-party websites.
Use of OpenStreetMap
The app uses the open-source mapping tool “OpenStreetMap” (OSM) via an API. The provider is the OpenStreetMap Foundation. To use the functions of OpenStreetMap, it is necessary to store your IP address. This information is usually transferred to and stored on an OpenStreetMap server. The provider of the app has no influence on this data transfer. OpenStreetMap is used in the interest of an appealing presentation of the app. Use of the app implies the use of OpenStreetMap, which is based on Art. 6(1)(a) GDPR (consent).
Further information on the handling of user data can be found on the OpenStreetMap privacy policy page.
