The user can subsequently add to or reduce such details in such user’s profile on the Application

4.1.1. Minors. Only persons legally capable to enter into agreements on their own behalf shall be permitted to register with “MasTrainer”.

4.3.1. “MasTrainer” reserves the right to reject users without giving reasons. In this event, any transmitted details will be deleted promptly

4.3.2. If you provide any information that is untrue, inaccurate, not current or incomplete, or “MasTrainer”  has reasonable grounds to suspect that such information is untrue, inaccurate, not current or incomplete, “MasTrainer”  has the right to suspend or terminate your account immediately and without prior notice and to refuse any and all current or future use of the Premium Services (or any portion thereof), without the Registered User being entitled to a refund of any previously paid amount.

4.3.3. In any event, “MasTrainer” reserves the right to contact you at any time to verify your registration data.

5.1. Fraud protection.

5.1.1. You must protect your account from unauthorized and fraudulent use. Please notify us immediately by email at hola@mastrainerapp.com, the same in the case of Premium Members, of any unauthorized or fraudulent use of your account, or if you suspect that your account may be at risk.

In most cases “MasTrainer” makes changes to “MasTrainer” Products and Services to enhance or improve them. We might also make modifications if such are necessary to comply with changes in legislation, technical and/or safety requirements or to reflect changes in our company and product strategy and to respond to the market and competitive situation. Insofar as the changes will not have a material adverse effect on your use of “MasTrainer” Products and Services, “MasTrainer” will not refund previously paid amounts, unless otherwise provided for in Section 7.


6.1. Subscription Requirement. In order to use the “MasTrainer” you must (i) be a Registered User, and (ii) pay the stipulated price, including applicable VAT, if any, and any other fees or amounts associated with the Premium Services, by credit card, via AppStores, or any other form of payment accepted by “MasTrainer”  (the «Subscription»).

6.2. Types and Prices of Subscription. “MasTrainer” offers three Subscription periods: MONTHLY, BIANNUAL AND ANNUAL, so that you can choose the one that best satisfies your needs. All subscriptions are automatically renewed until the user decides to cancel and/or withdraw. The different Subscription types and applicable prices are available for viewing here or in the App Stores. All prices are subject to change at “MasTrainer” discretion at any time. Any price changes will be announced on the Platform or in the App Stores.

6.3. Payment. Payment is made in advance for each subscription period. In other words, you can select the subscription period that best satisfies your needs to access the “MasTrainer” Premium Services. Once you signed up and paid for the Subscription, the selected validity period will be associated with your account.

6.3.1. Payments for the entire term of your Premium Membership shall be due immediately upon invoicing. Payment can be made using different online payment systems. If “MasTrainer” is unable to collect any fees from an account designated by the user due to lack of funds, the user shall bear all costs arising therefrom, including bank charges related to any debit entries or similar charges. “MasTrainer” and/or supplier companies may deliver invoices and payment reminders to the user by email.

6.4. Automatic Renewal. All subscriptions are automatically renewed until the user decides to cancel and/or withdraw. When your Subscription period expires, your credit card will be charged automatically with the standard subscription price which was valid at the time of Subscription, i.e., special offer prices do not apply in this case, and your Subscription will be renewed for the same period of time unless you cancel your Subscription, at least prior to the expiration of your current Subscription. The standard subscription price can be viewed on the Application and in the App Stores.

6.5. Cancellation. You may cancel your Subscription to “MasTrainer” Premium Service for Premium Members at any time by initiating the cancellation on the Platform or via the App Store. Unless otherwise provided for in Section 7 , “MasTrainer” will not refund previously paid amounts.

6.6. Expiration. Subject to Section 6.4 , for lack of a user’s cancellation of such user’s Subscription, each Subscription period ends only upon expiration of the agreed-upon time period, and regardless of the user’s actual use of the “MasTrainer” Premium Service for Premium Members during such period. Each user can check the length of the current Subscription period by viewing such user’s account information.

6.7. Contact. Please contact us for any questions you might have or to report any violations of the Premium Conditions in this Section 6 at hola@mastrainerapp.com, specifying the subject of the email as “Subscription“.

All users shall be given reasonable prior notice of the discontinuation of a “MasTrainer” Product. After the notification, Premium Members shall be able to use the App for the duration of their current Subscription period. Please note that during this period the two following limitations apply:

7.2. It may not be possible to download the App on another device.

7.3. “MasTrainer” will not update the “MasTrainer” Product during this period for any other purposes than security and conformity with the contract.
