1.2 Contracting Parties

By registering with Synaptikon, you as a user agree to these general terms and conditions (hereinafter referred to as "GTC"). The contract between the user and Synaptikon (hereinafter referred to as the "User Contract") becomes effective upon acceptance of the general terms and conditions and conclusion of the registration. These GTC form the legal framework for the use of the products. 


2. Scope of Application

The GTC apply to all users of Synaptikon products. Deviating and supplementary provisions upon formation of the contract shall only apply if they are made in writing; this shall also apply to deviations from the written form. The GTC apply equally to free (hereinafter referred to as "Freemium Account") and paid offers such as "Premium Brain Training Web & App", "Premium Brain Training App", and "Ease Premium" (hereinafter referred to as "Premium Account").


3. Scope of the Offer

3.1 Freemium Account and Premium Subscription

The functions and contents of the Freemium account in accordance with section 5 of these GTC are free of charge. No fees will be charged for limited and trial use or for registration. If the user decides to upgrade the freemium account to a premium subscription in accordance with section 6 of these GTC, the use of the premium subscription is subject to a charge. In order to guarantee a high quality of content offered within the framework of the Premium Subscription, fees are necessary. Expansion to a Premium Account and the fees associated therewith shall never arise for the User without express notification.

3.2 Right to Use

The right to use the offer exists only within the framework of the current state of the technology.

The claim to reimbursement of premium account services described under item 6 does not exist in the event of a temporary breakdown.



4. Registration, Contract Data and Formation of Contract

Registration data, in particular, the email address, will not be published, but will be treated confidentially and will only be used for the implementation and transaction of this user contract.

4.1 Registration via website


Each user may only register once. The email address will only be used in connection with Synaptikon's products and will not be passed on to third parties of Synaptikon.
The contract for the use of the products between the user and Synaptikon is formed by the user entering their email address, accepting Synaptikon's Privacy Policy by clicking on a checkbox, and clicking on the "Next" button.

Synaptikon will send the user an automatic confirmation by email upon receipt of the registration. This email contains a hyperlink with which the user verifies the correctness of the email address provided. The contract is only formed and the services are only activated when the user clicks on the hyperlink to verify the email address. If verification does not take place, Synaptikon may restrict or prevent access to the products at any time until the access has been verified (hereinafter referred to as "double opt-in").

Once the email address has been confirmed, the user has the option of changing the email address specified in the settings and requesting a new activation email.
Thereafter, the user is given the opportunity to order the paid exercises in the "Premium Subscription" via the menu bar "Premium", "Get Premium" and similar buttons, or via the "Shop", and thereby expand their Freemium account to a "Premium Subscriber Account". The user will be informed of the billing method, price and, if applicable, the duration of the contract in each case within the framework of the offers, and will receive a complete summary of this before completion of the order.

4.2 Registration via App

Registration via the app is similar to the registration process according to section 4.1 and differs only as follows: Instead of registering via the website, registration takes place directly via the app. Parts of the app can also be used without registration. However, an account can also be created here. For this purpose, the email address is requested (optional) and a confirmation email is initiated, which can only be sent if the user agrees to the GTC and the data protection declaration at the same time.
Just as in section 4.1, a double opt-in procedure is used to activate the user account after the email has been sent. After successful activation, the functional sequence corresponds to that according to section 4.1.

4.3 Contract Language

The contract language is English.

4.4 Correction of Input Errors

The user can correct input errors using the usual keyboard/mouse functions before sending their registration/order. The user can also cancel the process at any time by closing the browser window or the app. After clicking the registration/order button, input errors can no longer be corrected.

4.5 Storage of contract text

We save the text of the contract and send the user the order data and our general terms and conditions by email. The general terms and conditions can be viewed and downloaded by the user on our website https://sp.neuronation.com/tou. The user can view applicable orders in the user account.
In addition, the user can print or save these GTC https://sp.neuronation.com/tou by using the usual function of their internet browser (usually "File" -> "Save as"). The user can also download and archive these GTC as a PDF document. For this, the user should consult the instructions of their browser software, should they need help with this. To open the PDF file, the user needs the free program Adobe Reader (available at https://get.adobe.com/de/reader/) or comparable programs that can handle the PDF format.


5. Free Use of the basic functions of the products - Freemium Account

With the registration, no costs arise for the user. If the user has not purchased any premium exercises and courses, i.e. no premium account within the meaning of section 6 of the general terms and conditions, they shall be granted access to the exercises provided free of charge.
Fees are due for full access to the exercises within the framework of the premium account, insofar as this is stated and the user orders or books these separately. 


6. Paid services and products liable to costs - Premium-Account

 In addition to the free freemium account, Synaptikon also offers paid subscriptions, exercises, and courses on the website and via the mobile stores (Google Play Store, Apple iTunes App Store and others) ("Premium Account").
If prices are quoted, they include the applicable statutory sales tax.
The fee-based services vary according to the offer. The user will be informed of the billing type, price and, if applicable, duration within the framework of the respective offers and will receive a complete summary before the order is completed.

 6.1 Scope

 6.1.1 Purchases on the website

If the user purchases a premium subscription via the website, Synaptikon will activate additional "premium" exercises and courses. Synaptikon also reserves the right to offer individual web content, such as courses or exercises, for sale. In this case, the period of use is explicitly defined. Example: with the "Brain Training Premium Web & App" subscription, the user also acquires access to "Premium" content of the NeuroNation App.

6.1.2 Purchases through third parties and mobile app marketplaces

If the user gets access to "Premium" content via the mobile applications, the access extends to the content defined in the product (e.g. "Brain Training Premium-Subscription App" extends only to the Brain Training App, "Ease Premium-Subscription" only to the Ease App).
Synaptikon reserves the right to offer individual special services and content, such as courses, scientific coaching or exercises, in addition to the purchase. In this case, the period of use is explicitly defined.

Purchases or subscriptions within the App are made through the respective mobile marketplaces (e.g. Google Play Store or Apple iTunes App Store). These are subject to the respective terms of use of the marketplace provider.

6.2 Remuneration

While the use of a freemium account is free of charge, premium content (including virtual goods) is only activated after payment. The usage fees are calculated by Synaptikon on the basis of the price list valid at the time the contract is formed, any valid promotions and discounts, and are influenced by any valid promotional vouchers. The prices can be viewed at any time in the price list of the respective app or on the web on our website. In the event of an extension in accordance with Section 7.2.1 of these GTC, the regular price indicated for the ordered package will be debited. Different pricing increments can be offered at special conditions. These may include subscription payments or one-off payments.

6.3 Partial use free of charge

Parts of the premium product can be used free of charge as part of test or special promotions. In this case, the users have no claim to permanent use of these parts. Synaptikon will expressly designate the corresponding use as a test or special promotion. In this case, Synaptikon reserves the right to limit the scope at any time. Insofar as the user is subsequently granted the possibility of paid use, this shall be in accordance with the provisions of these GTC.
In this case, Synaptikon reserves the right to limit the scope at any time.

6.4 Technical Requirements for the use of the Premium Services

The user must ensure that their technical conditions are sufficient to use Synaptikon's products. In order to check the usability, the user receives some exercises for free use during registration. The usability may be restricted by an outdated browser or an older smartphone, a slow Internet connection, the lack of necessary plugins, etc. on the part of the user and make the offer only partially usable or not usable at all. The freemium account should be used to check these conditions before using the premium content. In the event of technical difficulties with the user's own equipment, the user has no claim to reimbursement of the amount paid by him.

6.5 Claims due to changes made to the Premium Services

The exercises and page features are subject to constant development and expansion, therefore Synaptikon reserves the right to change, delete, add or offer contents of the premium offer within the freemium scope. In this case, the user is not entitled to a refund of already paid amounts.

6.6 Contract Formation "Premium" and Delivery Time

The contract for the use of premium content is formed when the user decides on one of the offers on the website or via the app and the payment process is successfully completed.
The contract for the use of premium content is formed when the user decides on one of the offers on the website or via the app, and purchasing a "premium product" by entering their payment data, accepting the order summary and clicking on the "Buy", "Complete payment" button or a comparable field, with the payment process being subsequently successfully completed. The billing type, price and term are fully summarised before the order is completed.
In this case, the user is redirected to a website or a screen in the app, where it is pointed out that they can now use the purchased premium content. If this webpage is not displayed, the contract is formed with the first call of a content of the premium offer. Activation of the purchased service takes place immediately after the purchase. Non-digital products that require postal delivery will be shipped within 4 weeks after the purchase at the latest.

6.7 Payment Modalities for Purchases via App

The purchase of a Premium-Account via app is administered through the sites and billing arrangements of the Google Play store or Apple's iTunes App Store. The respective General Terms and Conditions of the Google Play or Apple's iTunes App Store apply to that transaction.

6.8 Payment Modalities for Purchases via the Website

The fees for a purchase of a Premium-Account via the websites of Synaptikon are due in advance. The User can conduct payment through the displayed payment systems, i.e. credit card or electronic or direct debiting scheme.

For a SEPA mandate, payment is executed within ten (10) banking days by our payment providers:

7. Duration and Termination

7.1 Freemium Account

The contract for using the Freemium-Account (basic contract) is concluded for an unlimited period and may be terminated by the User without notice at any time. To terminate the contract, the User can remove the registration data through the "Profile/settings" menu item by clicking on the "Delete User account" button. After that, the User receives an email with a link on which he must click to complete the cancellation of the account.

Synaptikon has the right to cancel the contract with the User should they violate the code of conduct described in paragraph 7.2.2. and 11 of this GTC. If the user has purchased a premium subscription (e.g. "Premium Brain Training Web & App", "Ease Premium" or "Premium Brain Training App"), they must first terminate the premium contract in accordance with the provisions in Section 7.2.1 of these Terms of Use. The deletion of an account entails the deletion of all User data including their scores, evaluations and comments.

7.2 Premium Services

The deletion of the user account does not automatically entail the termination of the contract. Proper notice of termination must entail a timely written termination of the contract.

7.2.1 Ordinary Notice of Termination

The Premium-Account is available in different packages and with differing contract durations. The terms can be found in the order confirmation email. The start of the respective term depends on the time of contract formation in accordance with clause 6.6. The subscription term is automatically extended recurrently by the contractually agreed duration (e.g. 1, 3, 6 or 12 months) unless the user terminates their contract no later than four weeks before the end of the respective term.

The notice of termination should be addressed to:



Synaptikon GmbH
Friedrichstraße 68

10117 Berlin

Deletion of a freemium account does not automatically result in termination of the premium subscription. Termination requires written cancellation. There is no entitlement to a refund of usage fees by non-usage of the product.

The receipt of the termination by Synaptikon is decisive for the time of the termination. Contracts of four weeks or less can be terminated at any time without a period of notice.

7.2.2 Extraordinary Termination

Both contract parties are entitled to end the Premium contract at any time due to extraordinary reasons. The latter include:

  • the User’s violation of NeuroNation’s code of conduct as described in paragraph 11 of this GTCs
  • the failure to adhere to regulations agreed to in the registration process
  • the failure to make payments two weeks after a reminder has been received
  • the case that the obtainment of NeuroNation in its current form – or any form – is no longer possible due to legislation changes
  • the disintegration of the company due to bankruptcy, the sale of the company or alternate business-related activities.
  • the User's proven loss of contractual capabilities

Attention: In contrast to the Freemium-Model, the deletion of the Premium-Account does not automatically entail the termination of the contract. To terminate the contract, a proper notice of termination entailing the shift to a Freemium-Account is needed.

7.2.3 Termination of Premium Services

If the Premium Membership is terminated through a proper notice of termination, the User’s Membership is shifted from a Premium- to a Freemium-Account. The data generated during the Premium-Membership remain and can be accessed through the purchase of a new Premium-Membership. The User himself has no claim to comparison and non-user specific data.

If the Premium Membership is terminated through an extraordinary notice of termination, the User’s account is not shifted to a Freemium-Account but deleted permanently. The deletion of an account entails the deletion of all User data including their scores, evaluations and comments.


7.2.4. Special modalities for users with regular residence in Germany

If you, as a user with regular residence in Germany, have purchased a subscription on or after the first of March 2022 (new contract), your subscription will be automatically renewed for an indefinite period after the end of the selected term and can be cancelled at any time after renewal with a notice period of no more than one month to the end of the respective billing period.


8. Notice of Cancellation

In regard to the payment due for the Premium-Membership, Synaptikon grants the User the right to a notice of cancellation (revocation) as described in the following:

Notice of Cancellation

The User has the right to cancel his contract agreement within 14 days from contract formation without giving reasons for the latter.

The User can also use the following form to inform Synaptikon about his notice of cancellation but is not obliged to do so.


Implications of the Notice of Cancellation:

The transaction will be undertaken in the same mode of payment that has been chosen in the first instance of payment unless both parties have agreed on an alternate mode of payment.
