Privacy policy

This privacy policy describes which personal data is processed when using pacerechner.de, for what purpose and on what legal basis — limited to what actually happens on this website.

1. Controller

The controller within the meaning of the General Data Protection Regulation (GDPR) is:

Peer Hoffmann
Mozartstr. 4
32545 Bad Oeynhausen
Germany

Phone: +49 (0) 5731 4960242
E-Mail: info@pacerechner.de

2. Visiting the website and hosting

This website is operated on a server of netcup GmbH, Karlsruhe. When you visit the website, the server processes the data technically transmitted by your browser (including your IP address, the time of the request, and the page requested) in order to deliver the website to your browser. The legal basis is Art. 6 (1) (f) GDPR (legitimate interest in the technical operation of the website).

I keep an access log to safeguard technical operations: it stores the IP address, the time of the request, the page requested, the HTTP status, the browser identifier (user agent), and the referring page (referrer). The contents of Authorization and Cookie headers are not logged. The data is automatically deleted after 14 days. The purpose is to detect faults and abuse and to ensure operational security; the legal basis is Art. 6 (1) (f) GDPR (legitimate interest in the secure operation of the website).

If a request identifies itself as a search engine crawler through its browser identifier, I compare its IP address with the address ranges published by the respective operator. If it does not match, I store the IP address, time and browser identifier of that request to detect abuse; this data, too, is automatically deleted after 14 days. The legal basis is Art. 6 (1) (f) GDPR.

3. Cookies and local storage

This website uses two technically necessary cookies: a session cookie that is set when signing in to a user account (see section 5), and a language cookie (lang, see below). Without the session cookie, signing in is not possible; since it serves exclusively to provide a service you have expressly requested, no consent is required for it under Art. 6 (1) (b) GDPR.

The language cookie lang contains only a language code (e.g. de or en) and no identifier; it is stored for 1 year, set only by me as first party, and, like any cookie, transmitted to my server with requests, but not evaluated or stored there. It is set when you actively choose a language – via the language notice (“This page is also available in …” → “Open in …” or “Stay here”) or the language selector – or when you open a link with a language specification in the address (#lang=…). It serves to remember your language choice, not to show the notice again, and to open the home page directly in the chosen language. The language notice itself only uses your browser’s language setting (navigator.languages), which is processed locally in the browser; your IP address is not evaluated and nothing is transmitted. When switching between pacerechner.de and calculatepace.com, your choice is passed on as part of the address (#lang=…, not transmitted to the server) and is likewise stored as a cookie on the other domain. The cookie is technically necessary for the service you have expressly requested, so no consent is required under Section 25 (2) no. 2 TDDDG (German Telecommunications Digital Services Data Protection Act); processing is based on Art. 6 (1) (f) GDPR (legitimate interest in user-friendly language guidance).

In addition, this website stores in your browser’s local storage (localStorage, not a cookie) whether you have unlocked external Amazon product images (see section 10) and whether you have unlocked the map display of the GPX calculators (see section 9). This information never leaves your browser and is not transmitted to me.

For audience measurement and advertising, further cookies or comparable storage mechanisms described in sections 7, 8 and 10 are added; to manage your consent, the consent management platform (section 6) stores your choice in your browser.

You can prevent cookies from being stored at any time via your browser settings, or delete cookies already stored. This may limit the usability of individual functions (in particular signing in).

4. Contact and feedback form

You can use the feedback form on this website to send me comments, bug reports, or suggestions for improvement. In doing so, your name, e-mail address, and message are transmitted to me by e-mail and processed there to handle your request.

The legal basis is Art. 6 (1) (f) GDPR (legitimate interest in responding to user enquiries) or, where the contact serves to initiate or fulfil a contractual relationship, Art. 6 (1) (b) GDPR. The data is deleted once it is no longer required to process the enquiry, at the latest once communication has concluded, unless statutory retention obligations require otherwise. The data is not passed on to third parties.

5. User account and sign-in

This website offers the option of creating a user account. During registration, your name, e-mail address, and a password are collected; the password is stored exclusively in hashed, non-reversible form. To confirm your e-mail address and to reset your password, I automatically send e-mails containing a confirmation link; an e-mail delivery service provider may be used as a processor for this purpose.

After successfully signing in, the website sets the session cookie described in section 3, containing a unique session identifier. For each session, your IP address and the identifier transmitted by your browser (user agent) are additionally stored to detect misuse and ensure session security.

Alternatively, you can sign in with an existing account at 321run.com (“shared sign-in”). In this case, 321run.com, as the identity provider, transmits your name and e-mail address to this website; if an e-mail+password account with the same e-mail address, verified at 321run.com, already exists, it is automatically linked to the 321run account instead of creating a second account.

The legal basis is Art. 6 (1) (b) GDPR (provision of the user account you requested). The data is stored for as long as the user account exists and is removed after its deletion, unless statutory retention obligations require otherwise. This data is not passed on to third parties other than the processors named and the identity provider 321run.com.

This website uses the consent management platform (CMP) “Google Funding Choices” provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland (“Google”). On first visit, the CMP shows visitors located in the European Economic Area, the United Kingdom, and Switzerland a consent banner, through which consent to the data processing described in sections 7, 8 and 10 can be given, refused, or managed individually per provider (IAB Europe Transparency & Consent Framework).

To provide this function, the CMP stores technical information in your browser — in particular the choice made, a timestamp, and a randomly generated identifier — and transmits it to Google. This technical management of consent is based on Art. 6 (1) (c) GDPR (fulfilment of my legal obligations regarding information and evidence of consent); the data processing selected in the banner is itself based on your consent (Art. 6 (1) (a) GDPR). You can change or withdraw your choice at any time via the “Privacy settings” link in the footer.

This may involve data being transferred to Google’s servers outside the EU/EEA; Google states that this is safeguarded via the EU-US Data Privacy Framework or standard contractual clauses.

In addition, when the consent banner loads, your browser retrieves technically necessary files (fonts and scripts of Google’s consent service) from servers of Google Ireland Limited (fonts.googleapis.com, fonts.gstatic.com, fundingchoicesmessages.google.com). The IP address of your device is transmitted to Google in the process, even before you have made a selection in the banner; I do not evaluate this data. These requests are technically necessary to display and manage the consent request; the legal basis is Art. 6 (1) (f) GDPR (legitimate interest in displaying and managing the consent request). The preceding paragraph applies to transfers to countries outside the EU/EEA.

7. Google Analytics 4 (audience measurement)

I use Google Analytics 4, a web analytics service provided by Google, which gives me statistics on the use of this website — for example, which pages are viewed and for how long. Google Analytics is only technically loaded and activated once you have expressly consented in the consent banner; before that consent, Google receives no data whatsoever via Google Analytics. The data processed after your consent (including a truncated IP address, device type, browser information, pages visited) may be transferred to Google servers in the USA. The legal basis is your consent (Art. 6 (1) (a) GDPR), which you can withdraw at any time with effect for the future via “Privacy settings”.

8. Google AdSense (advertising)

I display ads from Google’s Google AdSense service. Google AdSense may set cookies or use comparable storage mechanisms to show ads based on previous visits to this or other websites. Google AdSense ads are only loaded after you have agreed to the advertising-related data processing in the consent banner. As long as you have not given consent or have declined it, your browser retrieves neither ads nor ad scripts from Google. After your consent, Google may process technical data such as your IP address to deliver ads and transfer it to servers in the USA. The legal basis is your consent (Art. 6 (1) (a) GDPR), which you can withdraw at any time with effect for the future via “Privacy settings”.

9. Map display in the GPX calculators

The GPX evaluation pages (GPX pace calculator, bike GPX calculator) can display uploaded routes on an interactive map. I serve the Leaflet mapping library myself. The map tiles come from the tile server of the OpenStreetMap Foundation (tile.openstreetmap.org); they are only loaded after you have unlocked the map using the button displayed. In doing so, the IP address of your device is transmitted to the OpenStreetMap Foundation; I do not evaluate this data. Your unlocking is stored in your browser (see section 3) and then applies to all maps on this website. The legal basis is your consent (Art. 6 (1) (a) GDPR); you can withdraw it by deleting the stored website data in your browser.

I am a participant in the affiliate programme of Amazon Europe Core S.à r.l., 38 avenue John F. Kennedy, L-1855 Luxembourg (“Amazon”). As an Amazon Associate I earn from qualifying purchases.

Product images are loaded directly from Amazon’s servers. To prevent your IP address and further technical data (e.g. browser type, operating system) from being transmitted to Amazon already when a page is opened without consent, these images are blocked by default. Only once you click a placeholder or consent to data processing by Amazon in the consent banner (see section 6) are the images loaded; this unlocking then applies to all product images on this website and is stored in your browser (see section 3). The legal basis is your consent (Art. 6 (1) (a) GDPR). Without consent, the placeholders remain without an image being loaded; the product title, price, and purchase link are not affected by this. A withdrawal of consent takes effect from the next page view; images already loaded remain visible until then.

The purchase links point to amazon.de and are marked as affiliate links on the equipment pages. If a purchase is made via such a link, I receive a commission; the price does not change for you. Clicking such a link leaves this website; Amazon can tell from the affiliate identifier contained in the link that you came via this website. The further processing of data is subject to Amazon’s privacy policy.

11. Your rights as a data subject

As a data subject, you have the following rights under the GDPR:

To exercise these rights, an informal message to the contact details given in section 1 is sufficient.

12. No profiling, no automated decision-making

I do not engage in automated decision-making or profiling within the meaning of Art. 22 GDPR.

13. Changes to this privacy policy

I update this privacy policy whenever the data processing actually taking place on this website changes (e.g. when new services are integrated). The version current at the time of your visit applies.
