For the provision of the Professional Version of the Services, the User undertakes to pay the Provider the fees as specified on the Website (the “Fees”).
The Fees are collected through a third party by paying an in-advance annual subscription fee (the “Subscription”). By purchasing the Subscription through a third party, the User acknowledges that separate terms with such third party, in addition to the Agreement, may apply. If the User purchases a Subscription, they authorize the Provider to charge them automatically each year until they cancel.
The Provider may change the Fees from time to time. For existing Users of the given Services, price changes will take effect at the start of the next period of their Subscription following the date of the price change. The User accepts the new price by continuing to use the respective Service after the price change takes effect. In the event of a price change for Subscriptions, the Provider will, on its own behalf or through the respective third party through which the Subscription was purchased, notify the User in advance of any price changes and, if applicable, instruct the User on how they may reject these changes. If the User does not agree to the price changes and takes the prescribed action, the Subscription will expire at the end of its current recurring period and will not be automatically renewed.
The payment schedule with the third party through which the Subscription was purchased will automatically renew at the end of the applicable subscription period, unless the User cancels the Subscription before the end of the then-current subscription period. The User may cancel their Subscription through the third party according to their terms of service. The cancellation will take effect on the day after the last day of the current Subscription period.
If the User cancels the payment and/or terminates any of the Agreements before the end of the current Subscription period, the Provider will not refund any fees already paid.
The User understands and agrees that the Provider will exert reasonable efforts to ensure the provision of the Services, although they have no obligation to maintain, support, upgrade, or update any of the Services, or provide all or any specific Content through such Services.

Right of Consumer Withdrawal
The following provisions of this Article 4.4 only apply to those Users who are consumers in terms of the applicable legislation for the protection of consumers and the extent to which the right of withdrawal from the Agreement is granted to them under such legislation.
If the User purchases a Subscription, they may withdraw from the Agreement for any or no reason within 14 days from the moment of the purchase of the Subscription (the “Withdrawal Period”).
By purchasing a Subscription, the User explicitly requests that the Provider commence provision of the respective Services to the User immediately, therefore, before the end of the respective Withdrawal Period.
The User may withdraw from the Agreement by canceling their Subscription through the third party through which the User purchased the Subscription, according to their terms of service, or, if the cancellation through such third party is not possible, by contacting the Provider at email@example.com.
