Privacy policy
Information on how your personal data is processed on this website.
This English version is provided for convenience. The German version is legally binding.
1. Privacy at a glance
This website is designed to process as little personal data as possible:
- No cookies and no comparable storage on your device.
- No tracking or analytics tools (e.g. no Google Analytics) and no advertising.
- No forms – we do not collect any input on this site.
- Fonts and libraries (Leaflet, Chart.js) are served from our own server.
- Only the map loads content from an external provider (CARTO, see section 6).
Personal data is any data that can be used to identify you personally, such as your IP address.
2. Controller
MEKSOFT
Mehmet Emin Karagöz
Togostraße 3, 42277 Wuppertal, Germany
Phone: +49 159 06309209
Email: info@meksoft.de
The controller is the natural or legal person who, alone or jointly with others, decides on the purposes and means of processing personal data.
3. Hosting
This website is hosted by an external service provider:
RockingHoster Deutschland GmbH
An der Strusbek 21
22926 Ahrensburg, Germany
The hoster processes data only to the extent necessary to fulfil its service obligations and follows our instructions. We have concluded a data processing agreement pursuant to Art. 28 GDPR with the hoster. The legal basis is our legitimate interest in a secure, fast and efficient provision of our website (Art. 6 (1)(f) GDPR).
4. Server log files
The hosting provider automatically collects and stores information in server log files, which your browser transmits automatically:
- browser type and version
- operating system used
- referrer URL
- host name of the accessing computer
- time of the server request
- IP address
This data is not combined with other data sources. Processing is based on Art. 6 (1)(f) GDPR; we have a legitimate interest in the technically error-free display and security of the website. Log files are deleted after 14 days at the latest, unless further retention is required for evidence purposes.
Your language choice (German/English) is passed only in the page address and is not stored.
5. SSL/TLS encryption
For security reasons this site uses SSL/TLS encryption. You can recognise an encrypted connection by “https://” in the address bar and the lock symbol in your browser.
6. Map display (CARTO Basemaps)
To display the locations of measuring stations, we use map tiles from CARTO Basemaps (CartoDB Inc., 307 Fifth Avenue, New York, NY 10016, USA), based on OpenStreetMap data. When you open a page with a map, your browser loads the map tiles directly from CARTO's servers. In doing so, your IP address and technical browser information are transmitted to CARTO; a transfer to the USA is possible.
The legal basis is Art. 6 (1)(f) GDPR. Our legitimate interest lies in a clear, map-based presentation of the measuring stations, which is central to this site. CARTO does not set cookies through our site. More information: carto.com/privacy.
7. Fonts and libraries
The “Inter” font and the Leaflet and Chart.js libraries are installed locally on our server. No connection is made to Google or other third-party servers.
8. Measurement data
The environmental readings shown come from the citizen science project Sensor.Community. They do not contain personal data of the station operators; Sensor.Community publishes station locations rounded to about 100 m. Our server retrieves this data directly from Sensor.Community – your browser is not involved.
9. Contacting us
This site has no contact form of its own. The “Contact” link leads to the contact page of meksoft.de; the privacy policy published there applies: meksoft.de/datenschutzerklaerung.
If you contact us by email or phone, we process your request including the personal data provided (e.g. name, contact details, content of the request) in order to deal with your concern. The legal basis is Art. 6 (1)(b) GDPR where your request relates to a contract, otherwise our legitimate interest in handling requests effectively (Art. 6 (1)(f) GDPR). We do not pass this data on without your consent and delete it once it is no longer needed, unless statutory retention obligations apply.
10. Links to external websites
This site contains simple links (e.g. to Sensor.Community or meksoft.de). Data is only transmitted to the respective provider when you click a link; the provider's privacy policy then applies.
11. Your rights
Within the scope of the applicable legal provisions, you have the right at any time to:
- free information about your stored personal data, its origin, recipients and the purpose of processing (Art. 15 GDPR),
- rectification (Art. 16) or erasure (Art. 17) of this data,
- restriction of processing (Art. 18),
- data portability (Art. 20),
- withdraw consent you have given, with effect for the future (Art. 7 (3)).
Right to object (Art. 21 GDPR): where processing is based on Art. 6 (1)(e) or (f) GDPR, you have the right to object at any time, on grounds relating to your particular situation, to the processing of your personal data. We will then no longer process the data unless we can demonstrate compelling legitimate grounds for the processing that override your interests, rights and freedoms, or the processing serves the establishment, exercise or defence of legal claims.
Right to lodge a complaint: you have the right to lodge a complaint with a supervisory authority. The authority responsible for us is the State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia (LDI NRW), Kavalleriestraße 2–4, 40213 Düsseldorf.
To exercise your rights, an informal message to the contact details above is sufficient.
12. Objection to advertising emails
We hereby object to the use of contact data published under the legal notice obligation for sending unsolicited advertising and information material. We expressly reserve the right to take legal action in the event of unsolicited advertising, such as spam emails.
