• the termination of use of the application and the related rights and obligations.

1.4 The contract between us and the user is concluded in the Czech language.

1.5 These Terms and Conditions are made available to the user before the conclusion of the contract in a manner allowing them to be stored and displayed repeatedly.

2. Definitions

2.1 Application means the Jolt mobile application available through Google Play and the related digital services.

2.2 User means a natural person who uses the application.

2.3 Consumer means a user who, outside the scope of their business activity or independent exercise of their profession, concludes a contract with us or otherwise deals with us.

2.4 Account means the user profile created upon registration.

2.5 Jolt Premium means the paid premium version or subscription of the application offered in the application.

2.6 Google Play means the distribution and payment platform operated by a third party, through which the application may be downloaded, a subscription activated, payments charged, the subscription managed and, where applicable, payments refunded.

3. Description of the application and its main features

3.1 Jolt is an educational application focused on practising and acquiring knowledge through digital content, game elements and social features.

3.2 The application may include in particular:

• a user account,

• study content and practice cards,

• progress tracking,

• game elements such as points, levels or streaks,

• social features, for example friend codes, squads or duels,

• comments on cards,

• advertising,

• the Jolt Premium service.

3.3 The specific scope of features may vary depending on the version of the application, the device, the operating system or the current offering.

3.4 An internet connection, a compatible device, a supported version of the operating system and regular updates may be necessary for the proper functioning of the application.

3.5 Unless we expressly state otherwise, the application is not provided as a medical, financial, legal or other professional service and its outputs do not replace individual professional advice.

4. Registration and user account

4.1 Some features of the application may be available without registration, where the application allows this. Other features are available only after an account has been created.

4.2 When registering, the user is obliged to provide true, accurate and current data and, in the event of a change, to update it without undue delay.

4.3 The user is responsible for securing the access credentials to their account and for activity carried out through their account, unless they prove that the account was used without any fault on their part.

4.4 The user may not make their account available to a third party or allow it to be used in a manner contrary to these Terms and Conditions.

4.5 If the user has reasonable grounds to suspect that unauthorised access to their account has occurred, they are obliged to contact us without undue delay.

4.6 The application is intended for users aged 16 years and over.

5. Conclusion of the contract and technical steps

5.1 The contract for the use of the free part of the application is formed at the moment the registration is completed, the account is activated, or at the moment the user starts using a particular digital service, unless the nature of the service requires a different procedure.

5.2 If Jolt Premium is offered in the application, the contract for this paid performance is formed at the moment the user submits a binding order in the Google Play environment and that order is confirmed in accordance with the Google Play rules.

5.3 Before submitting an order for paid performance, the user is able to check and, where applicable, correct the data entered in the Google Play interface.

5.4 Immediately before the order is submitted, the user will be clearly informed of the main characteristics of the performance, its price, the length of the trial period, the duration of the commitment, the conditions of termination and other essential information.

5.5 If the order is placed by means of a button or a similar control element, that element will be labelled unambiguously so that it is clear that using it creates an obligation to pay.

6. Free version, price and Jolt Premium

6.1 Basic use of the application is free of charge.

6.2 The application may contain optional in-app purchases, in particular a Jolt Premium subscription.

6.3 Jolt Premium may be offered in particular in the following variants:

6.4 The current price of Jolt Premium will always be displayed before the order is completed in the Google Play environment.

6.5 Unless stated otherwise for a particular offer, upon expiry of the trial period the paid subscription will begin on the terms displayed in Google Play, unless it is cancelled before the trial period ends.

6.6 The administration of the subscription, its cancellation, invoicing, the payment method and any refunds may also be governed by the Google Play terms.

6.7 The user acknowledges that a subscription arranged through Google Play may have to be cancelled directly in the Google Play account.

6.8 If we offer discounts or promotional campaigns, their conditions will be stated with the particular offer.

7. The consumer's right to withdraw from the contract

7.2 The consumer may withdraw by any unequivocal statement sent to the e-mail address contact@joltapp.net.

7.3 If Jolt Premium or other paid digital performance is to be provided before the withdrawal period expires, we will obtain the consumer's prior express consent to commencing performance before that period expires and will at the same time inform them when and under what conditions the right of withdrawal ceases to exist.

7.4 If the right of withdrawal ceases to exist under the law after the provision of the digital performance has commenced on the basis of the consumer's express consent, the consumer will be clearly notified of this in advance.

7.5 Refunds, cancellations and other related processes may, in the case of purchases made through Google Play, also be subject to the rules of that platform.

8.4 We are entitled to make reasonable changes to the application. If a change to a paid service would significantly impair the user's access to the service or its use, we will inform the user of such a change in advance to the extent required by law and will grant them the relevant rights, including the option to terminate the commitment, where legislation so requires.

8.5 We do not guarantee continuous availability of the application without any outages. We may carry out maintenance, security measures or technical restrictions, to a reasonable extent.
