Privacy Notice – justtrack website & platform

Hey there – Welcome to justtrack.
Let’s talk about your privacy.

Your privacy and data security matter to us. This Privacy Notice is here to help you understand what information we collect when you use our websites and our Platform, how we use it, and what rights you have. Whether you’re just getting started or you’re a long-time customer, please take a few minutes to read through this notice carefully.


1. Who we are


We are justtrack GmbH, a company based in Hamburg, Germany.


Our address is:


justtrack GmbH
An der Alster 42
20099 Hamburg
Germany


We offer mobile and web app developers a set of tools for attribution, analytics, and campaign performance measurement. 


In doing so, we basically process three types of data: (i) data we may collect and process from users of our websites at the following domain: https://justtrack.io (hereinafter referred to as “our website”), (ii) Platform data – information about our customers (you or your company’s representatives) who use the justtrack Platform and (iii) End user data – data we process on behalf of our customers about the users of their apps. 


This Privacy Notice generally focuses on the first category — your data as a user of our website. However, as our “justtrack Plattform” is integrated in our website and accessible through our website, as our customer and user of the justtrack Platform, you will also find relevant all information on data protection in relation to the justtrack Platform within this Privacy Notice. This Privacy Notice therefore applies generally to data processing by us via our website, as well as if you are a customer or user of our justtrack Platform, unless some sections expressly refer only to our website or the justtrack Platform and all information relating specifically to the justtrack Platform can be found in section 7 of this Privacy Notice below.


Important note: If you are an end user of an app that uses justtrack technology (e.g., a mobile game), this privacy notice does not apply to you. Please refer to the privacy policy of the app you’re using, as the app developer is responsible for your data under applicable law.


2. Data Controller


justtrack GmbH, An der Alster 42, 20099 Hamburg (you will find exact contact details in Section 18. (“Contact”) of this Privacy Notice or in the legal notice at https://justtrack.io/imprint) is the “controller” in accordance with the applicable data protection law, in particular the EU General Data Protection Regulation (GDPR), for the processing of personal data in these webpage


3. Personal Data


Personal data is information that may be used to find out personal or factual characteristics about you (e.g. name, address, telephone number, date of birth or email address). Information with which we cannot create a link (or can only do so with disproportionate effort) to you personally, e.g. via anonymisation of information, is not personal data.


4. What Personal Data is collected and processed by us?


You can generally visit our website without informing us about who you are and without stating to us any corresponding personal data (e.g. names, address, telephone number or email address), unless you provide them to us voluntarily or the corresponding legal provisions on the protection of your data allow this.


5. Purpose


We will collect, process and use the personal data provided by you online only for the purposes stated to you.

Some data that we may collect about you is necessary in order for us to:


  • provide you with the services you desire;
  • perform our contracts with you;
  • comply with legal provisions (e.g. billing).

In situations where the law requires your permission (for example, if you sign up for our newsletter), we’ll ask for it clearly—and you can withdraw it anytime. If we directly collect data from you, we may ask for your permission and clearly label mandatory information (e.g. with an asterisk [*]). Any other details without a star will be provided by you voluntarily.


6. Legal Basis 


Following applicable GDPR regulations,  we need a valid reason — called a “legal basis” — to use your personal data. Depending on the situation, we may rely on one or more of the following legal bases for the processing of your data:


  • your consent to data use in accordance with Art. 6(1)(a) GDPR – in situations where the law requires your permission (for example, if you sign up for our newsletter), we’ll ask for it clearly — and you can withdraw it anytime.
  • the fulfilment of our service obligations resulting from the contracts concluded with you, in order to provide you with the desired services, in accordance with Art. 6(1)(b) GDPR – we need to process your data to provide you with access to our website or the justtrack Platform and fulfill our agreement with you, e.g., creating your account, offering support, or delivering features you’ve subscribed to;
  • our legitimate interests in accordance with Art. 6(1)(f) GDPR – we may use your data to run and improve our website or Platform, ensure it’s secure, prevent fraud, or better understand how people use our services—provided this doesn’t override your rights or freedoms, particularly
    • our commercial interests in the improvement of our services, so that we can better understand your needs and expectations and therefore improve our services for you;
    • for the prevention of fraud and to guarantee that the use of our web services, i.e. our website or the justtrack Platform, takes place completely and without fraudulent conduct;
    • in order to guarantee the security of our services and ensure that our offering is technically safe and works properly;
    • to secure and implement our contractual entitlements and claims.
  • Legal bases in accordance with Art. 6(1)(c) GDPR, if the collection, storage, transfer or other processing of the data is legally prescribed or necessary for the processing, in order to fulfil our statutory obligations – e.g. in some cases, the law requires us to process certain data — like keeping records for tax or regulatory reasons.

We will only process your personal data in accordance with the above-mentioned legal bases and the provisions of this Privacy Notice. Specifically, your data will be processed as described below.

  • Business partners, service providers, and sub-processors who help us run the Platform and process data on our behalf
  • Advertisers, social media platforms, and ad networks (when relevant to your use of the Platform)
  • Analytics and search providers who help us understand how the Platform is used and improve it
  • Affiliates or third parties in connection with company restructuring, mergers, or acquisitions – we’ll give you a heads-up if that happens
  • Authorities or legal advisors, if we’re legally required to share data or need to protect the rights, property, or safety of justtrack, our users, or others

We also want you to be aware that the Platform may include links to third-party websites, plug-ins, or apps. If you click on one of these, third parties might collect or share data about you. Since we don’t control those sites, we recommend checking out their privacy policies before interacting with them.


And lastly, if we’re ever legally required to – for example, by law enforcement or regulators – we may need to share your data with the appropriate authorities. We may also do so if we believe it’s necessary to protect the rights, property, or safety of justtrack, our users, or others.


8. Google Analytics


If you have agreed to the use of corresponding cookies, our website may use Google Analytics, a website analysis service of Google Inc., 1600 Amphitheatre Parkway Mountain View, CA 94043, USA (“Google”). Google Analytics uses so-called “cookies”, which are text files that are stored on your computer and enable an analysis of your use of the website. The information generated by the cookie about your use of this website will generally be sent to a Google server in the USA, where it will be stored.


We would also like to point out that Google Analytics has been expanded with the code “gat._anonymizeIp();” within our website in order to guarantee the anonymised logging of IP addresses (so-called IP masking). Before the transmission, your IP address will therefore be shortened by Google within member states of the European Union or in other signatory states of the Agreement on the European Economic Area. Only in exceptional circumstances will the full IP address be sent to a Google server in the USA, where it will be stored. The IP address sent from your browser as part of Google Analytics will not be matched with other data by Google.


Google will use this information on our behalf in order to analyse your use of our website, compile reports on the website activities, and provide the website operator with services associated with the website use and internet use. Google may also pass on this information to third parties, if this is legally required or if third parties process this data on behalf of Google. The legal basis for this data processing is Art. 6(1)(f) GDPR, which allows the processing of data to protect legitimate interests of the data controller.


You can prevent the storage of cookies by setting your browser software accordingly; however, we would like to point out to you that in this case, you may not be able to use all functions of this website to their full extent.


You can also prevent the logging of the data generated by the cookie and related to your use of the website by Google by downloading and installing the browser plugin available at the following link: http://tools.google.com/dlpage/gaoptout?hl=de.


As an alternative to this browser plugin or within browsers on mobile devices, you can prevent the logging by Google Analytics by deactivating the functionality option in the cookie settings. An opt-out cookie will then be placed, preventing the future logging of your data when visiting this website.

Your visit to our website or your use of our justtrack Platform will be automatically logged by our web servers.


In connection with the information requested by you from our websites, data is hereby logged for the provision of our various services or for analysis and security purposes, and may be stored in anonymous form (non-personalised). The web server used by us automatically stores data about the displaying of our webpages in so-called server log files. This data is as follows:


  • IP address
  • Referrer URL (the site from which you visit us)
  • Time of server request
  • Host name of the accessing end device (the name of your internet service provider)
  • Browser type and browser version
  • Operating system used and its settings

An automated amalgamation of this data with data from other data sources does not take place. If your IP address is automatically logged, it will be automatically deleted after 30 days at the latest. Otherwise, only general information is logged, e.g. when which content of our offering is accessed and what pages are visited the most frequently, the names of the requested files and their dates and times of access. This data is used to improve our services and does not enable matches to be made with you personally.


We will not use this information for any other purposes.


The legal basis for the data processing is Art. 6(1)(f) GDPR, which allows the processing of data to protect legitimate interests of the data controller.


13. Use of cookies


We do not create personal user profiles. In connection with the displaying of information requested by you, data is only stored on our servers in anonymised form, for the provision of our various services or for analysis purposes. General information is hereby logged, e.g. which content of our offering is accessed and when, and what pages are visited the most frequently. For these purposes, we use so-called “cookies” (small text files with configuration information). The cookies used serve in particular to determine the frequency of use and the number of users of our websites. This enables us to find out which parts of our websites and which other websites our visitors have visited.


However, these use data cannot be traced back to the users. None of this anonymously compiled use data will be matched with your personal data, and it will be promptly erased after the end of the statistical analysis.


Moreover, our website and the justtrack Platform do not store cookies that do not have only technically necessary functions and do not only enable the proper functioning of our webpages if you have not accepted them beforehand. For this purpose, you must agree before the storage of cookies by selecting the types of cookies you desire or accept and clicking on “Akzeptieren” (accept) on the banner that contains the notice on the storage of cookies. Further detailed information about the types of cookies we use and how to configure the use of individual types of cookies, and agree and object to their use, can be found in our cookie settings.


The legal bases for this data processing are Art. 6(1)(f) GDPR (which permits the processing of data for the protection of legitimate interests of the data controller) and Art. 6(1)(a) GDPR (which permits data processing based on your consent).


Most browsers are configured so that they automatically accept cookies. However, you can deactivate the storage of cookies or set your browser so that it notifies you before cookies are stored. Users who do not accept cookies may not be able to access certain parts of our website.


14. Data Storage


We only store personal data that you send to us for as long as we require it, in order to fulfil the purposes for which this data has been sent, or as long as this is stipulated by law:


  • If you conclude contracts with us, we will store and process your personal data for the duration the contract and beyond for the fulfilment of your post-contractual obligations and matters, and for the duration of the statutory retention periods (maximum 10 years).
  • If you have agreed to the use of your email address for marketing purposes, we will store your email address within our mailing database until you de-register or request that we erase the data.
  • If you send us a query, we will process your personal data for the duration of the processing of your query.

When we no longer require your personal data, we will erase it from our systems and records, or anonymise it so that it can no longer be identified. We can retain certain personal data in order to comply with our statutory and regulatory obligations, and to enable us to manage our rights (e.g. the assertion of our rights in court), or for statistical purposes (in anonymised form).


15. Forwarding of data


We will neither sell nor market your personal data to third parties, nor will we pass it on for other reasons, if this is not listed within this Privacy Notice. The passing on of your personal data without your explicit prior permission will only take place in the following cases, in addition to the other cases named in this Privacy Notice:


  • If necessary for the resolution of unlawful use or misuse of our webpages or for prosecution, personal data will be passed on to the criminal prosecution authorities and, if necessary, to third parties who have been harmed. However, this will only take place if there are specific indications of unlawful conduct or misuse. We are also legally obliged to provide information to certain public bodies upon request. These are criminal prosecution authorities, authorities that pursue administrative offences punishable by a financial penalty, and the financial authorities.
  • Forwarding to third parties bound to professional secrecy can only take place if this is necessary for the implementation of the contractual terms and conditions or other agreements, and our claims from contracts that you have concluded with us.
  • For the provision of our service, we are occasionally reliant on contractually bound third-party companies and external service providers, e.g. for the hosting. In such cases, information will be passed on to these companies or individual people in order to enable further processing. These external service providers are carefully selected by us and checked regularly, to ensure that your privacy remains protected, and they may only process the data for the purposes specified by us. They are also contractually obliged by us to only handle your data exclusively in accordance with this Privacy Notice and the German data privacy laws.
  • As part of the further development of our business, the structure of our company may change, in that the legal form is changed, or subsidiary companies, business units or components are founded, purchased or sold. In the event of such transactions, the customer information will be passed on, together with the part of the company to be transferred, with your consent. During any transfer of personal data to third parties to the specified extent, we will ensure that the further use takes place in accordance with this Privacy Notice and the relevant data protection laws, and we will ask for your permission.

16. Data Security


For the secure transmission of your personal data, we use so-called SSL encryption. This form of transfer is recognised as a secure form of data transfer based on our current knowledge. We endeavour to take technical and organisational security measures to protect your personal data against unintentional or unlawful erasure, changes or loss, and against unauthorised forwarding or unauthorised access. Our employees are accordingly obliged to maintain secrecy and data privacy.


In order to prevent the loss or misuse of the data stored by us, we take comprehensive technical and organisational safety precautions, which are regularly reviewed and adjusted to meet technological advances. If it is within our sphere of influence, we use in particular modern encryption techniques as well as a variety of other measures to prevent third parties from obtaining unauthorised information. You will recognise an encrypted connection when the address bar of the browser changes from “http://” to “https://” and you will see a lock symbol in your browser bar. If there is an SSL or TLS encryption, the data you exchange with us cannot be seen by third parties.


However, we would like to point out to you that due to the structure of the internet, it is possible that the data protection regulations and the above-named security measures of other persons or institutions not within our area of responsibility cannot be observed. In particular, data passed on in a non-encrypted form can be read by third parties, even if it is sent via email. We have no technical influence on this occurrence. In these cases, it is the responsibility of the user to protect the data it provides against misuse, by encryption or other methods.


17. Your rights as a data subject


As a data subject in the data processing, you have the following rights listed in this section.
