Privacy Policy

The protection of your personal data is of particular concern to us at BestFit (hereinafter referred to as „we“). Therefore we follow the legal requirements when collecting and processing your personal data. In the following, we would like to inform you in detail about the scope and purpose of data collection.

Status: May 2018

Principle of anonymous use of data

The use of our web pages is usually possible without giving personal data. Insofar as personal data (e.g. name, address or e-mail addresses) is collected on our pages, this is always done on a voluntary basis as far as possible. The creation of a customer profile is necessary for the use of our apps. This data will not be passed on to third parties without your explicit permission. You will find the legal basis for data protection in the European Basic Data Protection Regulation (DS-GVO), the Federal Data Protection Act (BDSG) and the Telemedia Act (TMG).

We would like to point out that data transmission when calling up our website or apps (e.g. when communicating by e-mail) can be subject to security gaps. Complete protection of the data against access by third parties is not possible.

When you access our website or apps, some information is transmitted. They also provide information about the end device used (computer, smartphone, tablet, etc.), the browser used (Internet Explorer, Safari, Firefox, etc.), the time of access to the website, the so-called referrer and transferred data volumes.

We cannot use this data to identify individual users. The information is used by us to determine the attractiveness of our offers and to improve their performance or content if necessary and to make them even more interesting for you.

Please read this privacy policy carefully.

Personal data

The term „personal data“ is defined in the Federal Data Protection Act. These are individual details about the personal or factual circumstances of a specific or identifiable natural person. This includes, for example, your civil name, your address, your telephone number or your date of birth.

Collection and processing of personal data

Personal data will only be collected by us if you provide us with it, for example, if you contact us, in particular when registering a BestFit account, placing an order, requesting information or publishing it within our BestFit App in your profile.

We only use the personal data provided by you as far as your data is necessary for the fulfillment and processing of our services.

We store your data as long as it is necessary for the fulfillment of the intended purpose, as long as the legal storage periods make storage necessary. Your data will then be deleted or blocked in accordance with legal regulations.

If you have any questions or concerns regarding this Privacy Policy, please contact us by email at

Data protection principles

BestFit undertakes to treat all personal data passed on to us by customers in accordance with the applicable data protection laws, in particular not to pass these on to third parties without previous permission. In the relationship between the parties involved, third parties are the respective providers of other services as well as the third parties that BestFit uses to process payments or to perform other contractual or technical services.

In particular, BestFit undertakes not to collect, store, change, block or delete the personal data protected by the Federal Data Protection Act for any purpose other than the legitimate fulfillment of the respective task, to disclose the data to third parties or make it accessible or otherwise use it. This obligation to maintain data secrecy shall continue until the deletion of the respective personal data.

Furthermore, our technical infrastructure ensures reliable protection against unauthorized access to and alteration of your data stored by us by unauthorized third parties (data security and integrity). We ensure that the basic requirements of the data protection regulations of German and European law (e.g. DS-GVO, BDSG, TMG) are complied with by us and our affiliated companies and service providers, even if data is processed and/or stored outside Germany. As far as possible and appropriate for BestFit, BestFit will also obligate the providers, organizers and the aforementioned third parties accordingly to the data protection.

„Anonymous data“ refers below to data that is not connected with personal data; individual persons cannot be identified on the basis of anonymous data.

„Health Data“ hereinafter means data relating to a physical or mental condition that may arise (even to a limited extent) in connection with a medical context.

Type and scale of data collected

Separate consent for health data

Partial services of BestFit are not possible without the collection, processing and use of health data. In this respect, you agree that BestFit may collect, store and use the health data provided by you for the purpose of establishing, executing or terminating the contract, as far as this is necessary for the above-mentioned purpose. A further use, in particular, passing on to third parties by BestFit, does not take place. If an evaluation is carried out for scientific purposes as well as for the purpose of constantly optimizing BestFit’s offer, the data will be anonymized and only this anonymous data will be used.

For the use of the website or the provision of services, BestFit collects various types of data, which are partly provided by the respective user and partly necessary for the use of the website or app or which arise through the use of the website or app and the services provided through it.

During the registration process, for example via the login, the basic data for the registration are transmitted to BestFit; the individual data are determined by the registration forms of the respective login and are only collected, stored and used for the use of the services provided by BestFit. In the context of such a registration BestFit is also entitled to inform the user about changes, additions or new versions of the website and about the information provided by the website.

If you wish to send e-mail messages or other communications, including but not limited to comments, to the Website Provider or post them directly on the Website, the Website Provider will retain such communications in order to process the User’s request, respond to questions and improve the Website, products and services. When a comment is published, the email address you provide will be stored, but not published. Your name will be published if you have not written under a pseudonym. If, for example, feedback is made available, the provider may use and disclose this feedback for any purpose, as long as the provider does not provide it with your personal data, unless you have separately authorized the provider to do so in individual cases. The collection of the data contained in such feedback and the handling of all personal data contained therein shall be in accordance with the above data protection principles.

The communication of health data takes place via an encrypted internet connection, the storage takes place on internet-connected servers in Germany. Excluded from this is any further communication via our website (and its subpages) or via our app.

Note on data transmission to the USA

According to the current case law of the European Court of Justice on the Safe Harbour data protection agreement with the USA, personal data can no longer be transferred to the USA with a data protection standard corresponding to that of the EU. BestFit only transfers the data expressly mentioned in this data protection declaration to the USA. At the same time, BestFit explains at the appropriate points the possibilities to prevent a transfer.

Registration of a BestFit account

Via our login system, you can create a BestFit account with which you can log in to all our offers after the first registration. We use cookies – small files – in your browser to identify you. All data that you store in your account is stored in a database of BestFit GmbH, Rintheimer Straße 15, 76131 Karlsruhe, Germany. Some of our offers can only be used if you set up a BestFit account.

For registration we only need the following data:

First name and surname

email address


You must also read our Privacy Policy and accept our Terms and Conditions, Cancellation Policy and Terms of Use. You also have the option to provide us with additional information such as your gender, training city, training studio, fitness level, goal and a profile photo, which you can change or remove at any time.

We also offer you the possibility to create your BestFit account via your Google or Facebook account. When you register with your Google or Facebook account, you will be informed which data we need from you from Google or Facebook – especially your public profile information, such as first name, last name, gender and your e-mail address, which you have deposited there. These are necessary for identification in order to create a secure BestFit account for you. This allows us to show you which of your friends are already at BestFit. Your Google or Facebook profile and your BestFit account will be permanently linked via the mail address. We store your mail details with us and will contact you at this address if necessary. We also remember that you signed in to us via Google or Facebook. Once you log in to Google or Facebook, you can also sign in to us. We will not share any information about you with Google or Facebook without your permission. Important: We never get to know your Google or Facebook access data and have no possibility to post anything in your Google or Facebook profile without your permission. You can find out how Google or Facebook handles privacy settings in Google’s or Facebook’s Privacy Notice and Terms of Use, which also describe the terms and conditions applicable to the above-mentioned ability to sign in and register with us. Other Facebook functions such as the Like button, which you will find in the following chapters of this privacy policy, have nothing to do with this registration option and will be played separately from your BestFit account.

Data collection, processing and use in the context of BestFit Apps

In order to use our BestFit App, you must have a BestFit account. You have already been informed above which data is collected for this purpose. In order to provide you with an optimal BestFit experience, the concept of BestFit is partly based on the publication of certain information from our users, including your information. So that you can decide for yourself if and which data you would like to publish, we present our program in more detail below. This includes, in particular, the following information:

Public profile (picture, user name, training location, training studio)

With the information in your public profile, you appear in the BestFit App. This information allows other users to see you within the BestFit App. Other users can see your user name and profile picture (if you agree), your training location and training studio.

The BestFit app stores all your successfully completed training sessions and the related information, such as uploaded photos or comments.

Thus some of your information is also available to other users within the BestFit App. We want to make sure that not everyone is alone with their training, but that their achievements are appreciated and serve as an incentive for newcomers.

Based on your entered data, successfully completed training sessions and your feedback on your already completed training sessions, you will receive personalized training plans. We use a complex algorithm to analyze the data you have entered, the training performance you have completed (training method, the time required, training weight, repetitions, etc.) and your feedback in order to be able to offer exactly the right training.

Furthermore, you have the possibility to enter the following settings when defining your training plan:

Define the goal (endurance, mass, definition, fat reduction, coordination)

  • Training sessions per week
  • Which muscle groups are to be trained and which are not
  • Prioritize muscle groups
  • Duration of a training session

Do you train with or without a partner?

We process these inputs in order to generate your training, taking into account your settings.

Evaluation of location data

Within our BestFit App, there is the possibility to enter location data. For this, we need access to the location data. These data allow us to show the number of visitors of the individual gyms.

In order to determine which regions of the world the most users are at home, we evaluate your location data statistically. For this purpose, we access the position data stored in the iOS device under „Frequent Places“. These data are forwarded to us without any reference to your person when using the app. We evaluate the collected position data exclusively statistically. Further information about the location function „Frequent Places“ of iOS devices and the possibility of deactivation can be found here.

Access permissions

We need these access options and information about the technical functionality of our app and to provide the services offered with the app, in particular, to access your camera or photos, to determine your training location or to send you push messages to inform you about news. We will ask for permission to access the individual functions and information during the installation process or before using them for the first time, and will only access these functions if you agree to a release. Depending on your operating system, you can manually revoke access rights in the settings. You can find out how this works in the manufacturer’s instructions for your mobile OS. Please note, however, that you will only be able to use the app to a limited extent, or not at all, without the appropriate permissions.

When you first use the corresponding functions, the following permissions are requested for the following purpose:

Google Analytics

In accordance with the agreement between Google and the Hamburg Representative for Data Protection and Freedom of Information, Google Analytics may be used in accordance with data protection regulations and without objection under certain conditions. In particular, we would like to point out that Google Analytics on our website has been extended to include a corresponding „IP masking function“ in order to guarantee an anonymous collection of IP addresses.

Please also note the following information about the use of Google Analytics: This website uses Google Analytics, a web analytics service provided by Google Inc. („Google“). Google Analytics uses so-called „cookies“. The information generated by the cookie about your use of this website will generally be transmitted to and stored by Google on servers in the United States. However, by activating IP anonymization on this website, your IP address will be shortened by Google in advance within member states of the European Union or in other contracting states of the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be transmitted to and truncated by Google on servers in the United States. On behalf of the operator of this website, Google will use this information for the purpose of evaluating your use of the website, compiling reports on website activity and providing other services to website operators relating to website activity and internet usage.

The IP address transmitted by your browser as part of Google Analytics is not combined with other data from Google. You may refuse the use of cookies by selecting the appropriate settings on your browser, however, please note that if you do this you may not be able to use the full functionality of this website. You can also prevent Google from collecting the data generated by the cookie and related to your use of the website (including your IP address) and Google from processing this data by downloading and installing the browser plug-in available under this link.

Google Tag Manager

For reasons of transparency, we would like to point out that we use the Google Tag Manager. The Google Tag Manager does not collect any personally identifiable information. The Tag Manager makes it easier for us to integrate and manage our tags. Tags are small pieces of code used, among other things, to measure traffic and visitor behavior, measure the impact of online advertising and social channels, set up targeting, and test and optimize websites. If you have made an opt-out, the Google Tag Manager will take that opt-out into account. For more information about the Google Tag Manager, click here.

Google AdWords

To draw attention to our services, we place ads on Google AdWords. These are displayed on Google after search queries. With the help of cookies, we register how many users have found us via one of our ads. The resulting anonymous statistics enable us to optimize our ads. The cookies are stored by Google when you click on an advertisement and can be prevented via the settings of your browser. In this case, your visit to our website is not included in the anonymous user statistics. Further information can be found in the Google website statistics.


The BestFit App uses AppsFlyer, an analysis service of AppsFlyer Ltd. The information generated by the AppsFlyer about the use of the BestFit App is usually transferred to a server outside Germany and stored there. In the code of the BestFit app we have activated IP anonymization so that the IP address of the user is shortened before it is stored by AppsFlyer Ltd. On our behalf, Google and AppsFlyer Ltd. will use the anonymous information to evaluate the use of the BestFit App, and to compile reports for us about your activities in the BestFit App. In the privacy settings of your device, you can further restrict the way Google Analytics and AppsFlyer work. You can also send an email to if you don’t want to allow AppsFlyer. For more information about Google’s privacy policy, click here.

Data transfer to third parties

External service providers and partner companies receive your data only to the extent necessary to provide the service you have purchased. In these cases, however, the amount of data transmitted is limited to the minimum required. Insofar as our service providers come into contact with your personal data, we ensure that they comply with the provisions of the data protection laws in the same way. Please also note the respective data protection information of the providers.

The respective service provider is responsible for the content of external services, whereby we check the compliance of the services with the legal requirements within the scope of reasonableness.
