May we process your personal data?

We may only use personal data for a reason (so called ‘legal basis’) stated in the privacy laws. Under the General Data Protection Regulation (GDPR) the legal basis is listed in Article 6 GDPR.

Performance of the agreement
The main legal basis on which we process personal data is because it is necessary for the performance licensed use of the app. That way we can provide the services you are expecting from our app; or verify that you have a valid subscription; or properly address any complaints (legal basis: Art. 6(1)(b) GDPR).

Legal obligation
In some cases we might be obligated by law to process/archive personal data (legal basis: art. 6(1)(c) GDPR).

Legitimate interests
We process personal data for our legitimate interest. The interests or fundamental rights and freedoms of our users is never harmed in any way. Hereafter we explain when there is a legitimate interest.

We store the IP-address of app-users to secure the app and try to prevent illegitimate use of the app or your account.

We analyse what content is liked by our users in order to improve the app and its content in anonymized form.

We analyse in-app behaviour and system stability to improve the app for our users in anonymized form, so that no processing of personal data actually occurs. For this purpose we use Google Analytics for Firebase and Firebase Crashlytics. This way we can analyse which pages, content or UI-elements perform best or require (stability) improvements so we can further improve the app.

This requires Google Firebase to store, among other things, the device models, app updates, operating systems, number users and sessions, session duration, geography. Please note, Firebase does not collect any personal data. You can find a detailed overview of the data collected by Google Firebase at:

The information is transferred anonymously to a Google server in the USA and stored anonymously. Google will also use said information to evaluate the use of the App and to provide GAINSBYBRAINS other services regarding the use of the app without being traceable to a user.

Google Firebase Crashlytics is used by us for further improving the app. It collects information about the device used and the usage of our App (e.g. the timestamp, when the App was started and when the crash occurred), which allows us to diagnose and solve stability problems. All data is stored anonymously.

Google uses the advertising ID of your device for the required data transmissions. This also allows you to restrict the use of the advertising ID (for iOS: go to Privacy -> Advertising -> No Ad Tracking & for Android: go to Account -> Google -> Ads).

Additional information about Google Firebase can be found at:

Google might use subcontractors which can be found at:

In case consent is the legal basis for the processing of your personal data, we will inform you in advance why we use the information. Please note that you can withdraw your consent at any time. From that moment we will no longer process your personal data, unless there is (also) another legal basis for processing your personal data (legal basis: art. 6(1)(a) GDPR). For the sake of completeness, hereafter we inform you additionally for the purposes for which we ask your consent:

If you enabled push notifications we can inform you about news and updates if the app is closed. These notifications require communication with Apple Push Notifications (for iPhones) and Google's Firebase Cloud Messaging (for android devices). These notifications services can’t identify you or obtain personal info. To send you the notifications a secure key is used that is stored in the app itself.


How do we secure your data?

The privacy of our users is important to us. In developing our app, we have tried to keep the applicable privacy principles in mind as much as possible.

We do not keep your personal data for longer than necessary for the purpose for which we process your data.

Upon deletion of your account, or any request to remove your data, the data will be no longer retained than 14 days, unless there is another legal basis for the processing.

In order to perform our services it is necessary to share data with other parties (third parties). For instance a hosting company to store the data. This may be within the Netherlands as well as within the European Union (EU). If we share your data outside the EU, we will inform you.


What are your rights?

You have several privacy rights. For example, you can ask us what personal data we process about you. And if the data is incorrect, you can request to correct it. Also, in some cases you can ask us to delete, transfer or restrict the processing of your data. Please note that restricting the processing of your personal data, can affect or prevent the performance of the app.
