2. Which of your data do we collect, process or use?

a) Collection and use of location data

Our apps offer the possibility to retrieve weather data for your specific location. To this end, it is essential for the location service function on your mobile device to be enabled. As soon as the service functions have been enabled and before you start the app for the first time, you will be asked to permit access to the location data. After your OK, the app has permanent access to the information of the specific location. In the settings function of your mobile device, you can disable the access of the specific app to your location at any time. In the event the access to the respective data by the app is enabled, your mobile device will transmit to us the location in the radio cell you are in. In the event your mobile device has a GPS receiver, also this location data will be transmitted to us. The location information is rounded to 0.025° (a radius of about one-two miles) so that your specific location is not disclosed to us.

b) Paid version

The purchase of the relevant pro-version allows the use our apps free of ads. In the event of the purchase of a pro-version, we will only store a device-specific ID and the date of purchase.

c) In-App_Purchases

An in-app purchase allows you to use our apps free of ads. In the event of an in-app purchase, we will only store a device-specific ID, the date of purchase and the expiry date.

3. Which of your data is collected, processed or used by third parties

a) Usage-based online advertising

In the following, we wish to inform you about the data collected, processed and used by our advertising partners:

aa) Data collection in our apps

In our free apps, advertising is displayed. Within the scope of these ads, personal data are collected or used. During the advertising delivery we and our advertising partners use IP address, anonymous device identifiers (advertising-ID) and device information (operating system or version, device ID and language) as well as the data mentioned under 2.a) in order to be able to place relevant ads for you.

bb) Who our advertising partners are and how you can object to data collection for usage-based online advertising by our advertising partners

The following advertising partners are responsible for data collection for the delivery of usage-based online advertising:

Hide list of advertising partners

The processing of personal data (IP address, cookies, device identifiers) is based on your consent (within the meaning of Art. 6(1)(a) DSGVO) or, where applicable, on the legal basis of legitimate interest (Art. 6(1)(f) DSGVO). WetterOnline participates in the IAB Europe Transparency & Consent Framework and adheres to its specifications and guidelines. WetterOnline uses the consent management platform with identification number 6. You can adjust or revoke the personalised ads and the related data collection and processing via the privacy settings.

b) Collection, processing, and use of data at INFOnline Measurement

Our application uses the multi-stage measurement procedure 'INFOnline Measurement' from INFOnline GmbH ( to determine statistical parameters (page impression, visit, technical client) about the use of our digital offering. The usage measurement aims to statistically determine the intensity of usage, the number of uses and users of our application, and their surfing behavior - based on a uniform standard procedure - and thus obtain values that are comparable throughout the market. As a member of the "Informationsgemeinschaft zur Feststellung der Verbreitung von Werbeträgern e.V." (IVW –, the usage statistics are regularly provided by the IVW with the performance values 'Page Impression' and 'Visits' in the IVW report (

I. Basis for data processing

Measurement with INFOnline Measurement (pseudonymous system: IOMp) by INFOnline GmbH takes place within the framework of usage measurement with consent under Art. 6 para. 1 lit. a) DSGVO.

The purpose of the processing of personal data is the creation of digital performance values (page impression, visit, and technical client) for the creation of statistics.

The statistics are used to track and document the use of our offer.

II. Types of data

The data collected with INFOnline Measurement does not enable a user to be identified as a person due to the types of data and the amount of data. Measurement libraries are used that automatically integrate and execute the necessary measurement sensors for anonymous (IOMb) and/or pseudonymous data processing (IOMp) to determine the key figures when the app (client) is called up. In the anonymous census procedure (IOMb), there is no processing of personal information at all, in particular the IP address. This is completely removed from communication and processing. For this purpose, a communication interface, the so-called 'service platform', prevents the exchange of the user's IP address with the INFOnline systems within the framework of the INFOnline Measurement. The IP address as personal data is discarded in the census procedure on the service platform before the measurement call is forwarded to INFOnline. There is also no geolocation using IP addresses. The data set generated in the census procedure is a pure PI data collection. With the pseudonymous measurement procedure (IOMp), the following data is collected with the measurement library, which has a personal reference according to the EU Data Protection Regulation:

IP address: On the internet, every device needs a unique address, the so-called IP address, to transmit data. The storage of the IP address, at least for a short time, is technically necessary due to the way the internet works. The IP addresses are shortened by 1 byte before any processing and are only processed anonymously. Untruncated IP addresses are not stored or processed.

A randomly generated client identifier: Range measurement uses unique identifiers of the end device or a signature created from various automatically transmitted information from your device to recognize computer systems. A measurement of the data and subsequent assignment to the respective identifier may also be possible under certain circumstances if you call up other applications that also use the pseudonymous measurement procedure of INFOnline GmbH. The following unique identifiers can be transmitted to INFOnline GmbH as a hash:



Vendor ID

Personal data in the sense of the EU-DSGVO are only used for measurement insofar as the use of a library/ SDK is carried out for a user who has been assigned an individual IP address and a randomly generated client identifier for calling up app content. The pseudonymous measurement (IOMp) is only carried out in the presence of positive consent from the user from the Consent Management Platform (CMP).

III. Utilisation of data

The INFOnline GmbH measurement procedure used in this app determines usage data. This is done to collect the performance values page impression, visit, and client.

Geolocation: The allocation of app usage to the location of the call takes place exclusively based on the anonymized IP address and only up to the geographical level of the federal states/regions. Under no circumstances can a conclusion be drawn about the specific place of residence of a user from the geographical information obtained in this way.

Merging of usage data across offers: The usage data of a technical client (e.g. a browser on a device) is merged across applications and stored in a database.

IV. Duration of data storage

The full IP address is not stored by INFOnline GmbH.

The IP address is only used to receive the data packets and is then shortened by 1 byte. In the census procedure, the shortened IP address is discarded; in the pseudonymous procedure, it is stored for a maximum of 60 days. In the pseudonymous procedure, the usage data is stored in connection with the unique identifier for a maximum of 6 months.

V. Data transfer

The IP address as well as the shortened IP address are not passed on.

VI. Additional information

Further information on data protection in the measurement procedure can be found on the website of INFOnline GmbH (, which operates the measurement procedure.
