1. Order Submission Procedure and Sale Formation

The contract of sale/provision of services between the Company and the Student of the online store is considered to be formed according to the terms below.

1.1. Order Submission

After the Student selects the product/products and adds them to their shopping cart, they proceed to submit their order by selecting the corresponding icon labeled "Complete," which constitutes an offer to the Company to purchase the product or receive the service.

Before submitting the order, the Student must select the activation of the corresponding icon labeled "I have read and accept the Terms & Conditions and the Privacy Policy," which explicitly and unconditionally declares that before submitting their order, they have received a clear and understandable knowledge of the content of these terms, as well as the following information:

  • The main characteristics of the product or service ordered, as described on the online store's pages. The Student must check each relevant characteristic before submitting their order to ensure they have no doubts about the characteristics and properties of the ordered products.
  • The identity, address, phone number, and email address of the Store, as well as, where applicable, the supplier of the ordered products.
  • The total price of the order's products, including VAT, any other fees, and all additional charges and expenses associated with the delivery/receipt of the product/service. When these charges cannot be reasonably calculated in advance, the fact that such additional charges may be required is made known to the Student during the order completion process. The listed prices of the products in the online store are final (including the applicable VAT).

In the event the Student makes a mistake during the order submission process (e.g., with the chosen products or personal information), they can return by clicking the icon labeled "return" in their browser and correct the details. If the Student discovers their mistake after submitting the order, they must immediately inform the Company through its official communication channels.

1.2. Acceptance of Order - Contract Formation

1.2.1. Order Processing

Next, the Company processes the order and verifies the accuracy of its content concerning the listed prices (absence of errors in prices) and the accuracy of its details concerning the availability of products.

It should be noted that if the listed price of the products contains an error and does not correspond to the price in effect based on the Company's pricing policy at the time of order submission, due to a typographical or computer error, the Company is under no obligation, based on the principle of good faith and commercial ethics, to accept the order and enter into a contract for the sale of products or provision of services.

If discrepancies in the price are found for the aforementioned reasons, the Company is entitled to cancel the order after informing the Student accordingly.

1.2.2 Product Availability

If the product ordered by the Student is not available, the Company reserves the right not to accept the order, and therefore the contract between the parties will not be formed.

The Student will be informed in cases of discrepancies between the estimated delivery time of the products, as shown on the product page, and the actual delivery time of the products, which the Company discovered during order processing.

1.2.3 Contract Formation

Provided the Company does not find any errors that require correction and notification to the Student, it accepts the order and sends an email or text message to the Student (with the subject line "Order Acceptance and Shipment") to inform the Student about the completion/shipment of the order. At this stage, the sales contract is formed, and the obligations of the parties under the contract are activated.

2. Price of Products and Payment

2.1. The prices of products in euros are final, including applicable VAT, and are set at any given time on the product pages of our Online Store. The listed prices do not include the shipping costs of the products, which are calculated during order submission and are specifically indicated next to the relevant icons on the "shopping cart" and "checkout" pages. Prices may change at any time without affecting prices for any orders already submitted for which the Customer has received an order acceptance notification.

2.2. Once the Student has added the products/courses/services they desire to their shopping cart, the next step is to submit their order by clicking "Complete" and paying in full. The Student can choose the available payment method, either by credit/debit card or electronic payment methods (PayPal).
For credit and debit card payments, the Student is transferred to the secure environment of Alpha Bank (Nexi e-Commerce) for maximum transaction security.
All payments made using cards are processed through the electronic payment platform "Nexi e-Commerce" of Nexi Payments Greece S.A. and use TLS 1.2 encryption with 128-bit encryption protocol (Secure Sockets Layer - SSL). Encryption is a way of encoding information until it reaches the intended recipient, who can decrypt it using the appropriate key.
It should be noted that the Company does not receive or retain any payment card information. The details are provided solely in the secure environment of the bank, and the user is advised to carefully read the terms provided in that environment before entering their card details. The Company is not responsible for any harm the user may suffer during this process. The non-approval of payment by the card issuer does not create any liability for the Company, as the contract will be considered as not formed. All payments made using cards are processed through the bank's electronic payment platform. The technical measures for transaction and communication security used while browsing the aforementioned platform are exclusively under the control and responsibility of the aforementioned Bank.

3. Order Delivery - Shipping Costs and Methods

3.1. Order Delivery Details

Subject to the provisions of clause 1.3.2 above regarding the availability of products and the existence of exceptional circumstances, the Company makes every effort to complete the order by the date specified in the "Order Acceptance" or, if a delivery date has not been set, within 30 calendar days from the date of the "Order Acceptance." In any case, the Company is committed to delivering the product within thirty (30) calendar days from the acceptance of the order.

Access to digital products/services/courses is granted to the Student automatically and immediately, and in case of technical problems, within twenty-four (24) hours from the acceptance of the order.

It is noted that the Company is not responsible for delays in the execution of the order (including delivery), which extend beyond the maximum periods stated above, and which are due to circumstances not attributable to the Company's fault or due to force majeure. In these cases, the Company is entitled to extend the time for the execution of the order. Indicative examples may include strikes, terrorist acts, war, supplier/transport/production issues, exchange rate fluctuations, government or legislative actions, and natural disasters.

If such incidents last longer than forty-five (45) days or - for digital products/services - seven (7) days, the sales contract may be terminated by either party without compensation. If the Student determines, at any time during the force majeure period, that they no longer have an interest in the execution of the order, they are entitled to terminate the sales contract without penalty, and the Company must refund the price and any other amount paid under the sales contract.

3.2. Shipping Methods

This paragraph applies only to products delivered in person and does not apply to digital products/services/courses.

The Student can choose from the available shipping methods when finalizing their order. If they choose to have the products shipped via a courier company or transport company, the Student is automatically informed on the "order confirmation" page about the shipping costs, which are calculated based on the order and are borne by the Student.

When the order is ready for shipment, the Student receives a notification either by email to their email address or by text message to their mobile phone.

If the Student does not accept/refuses to receive an order that has already been sent to them due to their own fault, they are liable for the shipping costs already paid, as well as any additional shipping/return costs incurred due to their refusal. In this case, it is agreed that the Company is entitled either to deduct these additional costs from the payment or to demand payment from the Student.

If the Student wishes the products to be shipped to a carrier of their choice, the Company, upon the Student's instruction, agrees to deliver the products to the carrier and is responsible up to the point of delivery of the products to the carrier. The Company is not responsible for the non-delivery/destruction of the products upon final delivery, and the Student has no claims against the Company due to such non-delivery/destruction.

3.3. Shipping Costs

Shipping costs are automatically calculated based on the volume, weight of the products, and the delivery location. The Student is informed on the "checkout" page about the shipping cost of the products. In the event of discrepancies or special cases, the Student will be informed by phone or email from the Company about the shipping costs.

This paragraph applies only to products delivered in person and does not apply to digital products/services/courses.

4. Right of Withdrawal

4.1. Right of Withdrawal

If the Student is a natural person who transacts with our Company for personal use and not in the exercise of their professional activity (e.g., commercial, artisanal, business, or self-employed professional activity), they have the right to withdraw from the contract without giving any reason and without any cost, within fourteen (14) calendar days from the day of receiving the product or service by the Student or another person authorized by the Student to receive it. In case the order includes many products that are delivered separately, the deadline for exercising the right of withdrawal starts from the day the last product was received by the Student or their authorized representative.

To exercise the right of withdrawal, the Student must send the relevant request to the email address This email address is being protected from spambots. You need JavaScript enabled to view it., and our Company is obliged to confirm in writing the receipt of the withdrawal statement as soon as it is received.

Alternatively, the Student may notify the Company through the communication channels it maintains about their intention to withdraw from the contract, and the Company will confirm that it has received the withdrawal statement and/or guide them accordingly. To withdraw in time, it is sufficient for the notification (by the methods mentioned above) to have occurred within the aforementioned exclusive period of fourteen (14) calendar days.

ATTENTION!!: The contents of this term do not apply to digital products, services, and courses for which the Student waives the right of withdrawal, as provided for in clause 4.3.

4.2. Consequences of Withdrawal

ATTENTION!!: This section does not apply to digital products and services, as outlined in clause 4.3. In the case of purchasing digital products/services/courses, please refer directly to the return policy chapter of these terms and conditions (Chapter 5).

In the event of a lawful withdrawal as per the above, the Company is required, within fourteen (14) calendar days from the day it received proven knowledge of the Student's decision to withdraw from the contract, to return the payment it received, including delivery costs. However, if the Student had chosen a different delivery method, one more expensive than that offered by the Company, the Company will not cover the additional delivery costs. It should be noted that the Company may withhold the refund either until it receives all the products back or until it receives proof of their return, whichever occurs first.

The refund will be made using the same payment method that the Student used for the original transaction. In particular, in the case of the Student being charged via credit card, the Company, provided it has received the payment from the bank, will be obliged to inform the bank about the cancellation of the transaction, and the bank will take the appropriate action. Once the Company has provided this information, it bears no responsibility for the time and manner in which the counter-debit is executed, which is governed by the contract established between the issuing bank and the Student.

The Student must return the products without undue delay and in any case within fourteen (14) calendar days from the day they informed our Company that they are withdrawing from the contract. It should be noted that the deadline is deemed to have been met if the Student has provenly sent the products back before the end of the fourteen (14) calendar days.

Students located in Greece will not incur any return shipping costs in the event of withdrawal.

Students located outside Greece will be responsible for the return shipping costs, whether the return is done by mail or by any other means.

It should be noted that if the Student has used the product prior to their declaration of exercising their right of withdrawal, beyond what is necessary to determine the nature, characteristics, and functioning of the product, resulting in a reduction in the product's value, they are obliged to compensate our Company for an amount proportional to the above-mentioned reduction in value. This compensation may be offset against the amount the Company owes the Student and deducted from the amount to be returned.

4.3. Exceptions to the Right of Withdrawal

The aforementioned right of withdrawal does not apply to:

  • Orders that involve access to our platform's digital products, courses, and services online when:
    • You have given your consent to access the content before the end of the withdrawal period, and
    • You have acknowledged that by doing so, you waive your right of withdrawal.
  • Products manufactured according to the Student's specifications or clearly personalized (e.g., private online lessons).

5. Returns Policy for Digital Products/Courses/Services

At our Company, we aim to offer the best possible user experience and provide as much information as possible about our courses, products, and services. We also make sure to post a wide variety of free courses and advice on our Company's social media so you can have an even better idea of what you can expect from our paid content on our platform.

If, despite your purchase of a digital product, course, or service from our platform, you are not satisfied with its content, you have the right to request a refund within forty-eight (48) hours of your purchase.

If you wish to request the above refund, you must email us at "This email address is being protected from spambots. You need JavaScript enabled to view it." within 48 hours of your purchase, informing us of the reason you wish to request the refund. Alternatively, if you have registered as a member on our platform (user account), you can submit the request by clicking on the option "Personal Profile // Orders // Actions // Contact Us about your order," which appears in your profile.

  • You have not used/accessed the entire digital content of the course/product.
  • You have not received/downloaded all files included in a course.
  • You are not submitting your request in bad faith or abusively.

6. Claims Due to Defects or Lack of Agreed Quality

The right of withdrawal under Chapter 4 and the right of return under Chapter 5 of these terms do not apply to defective products or products that lack agreed quality, which are covered by their respective warranties.

6.1. Legal Guarantee

In cases where the Business is responsible for potential defects in the product or lack of agreed quality ("legal guarantee"), the Student is entitled, at their choice, to:

i) Demand, without charge, the correction or replacement of the product with another, unless such an action is impossible or requires disproportionate expenses,

ii) Request a reduction in the price, or

iii) Withdraw from the contract, unless it is a minor factual defect.

If the Student chooses the correction or replacement of the product, the Business must proceed with the correction or replacement within a reasonable time.

The above statutory rights of the Student regarding movable items apply for a period of two years, after which they become time-barred (Art. 5 of Law 2251/1994 & Civil Code 540).

Limitation of Liability: Our Business is exempt from the above obligations if it informed the Student and the Student was therefore aware in advance of the lack or defect in the product. Additionally, our Business does not provide any guarantee or warrant the suitability of the sold product for any specific purpose or use.

It is noted that the rights pertain to defects in the product upon receipt. They do not cover wear and tear expected due to normal usage of the products.

The Business is not responsible for the lack of or improper fulfillment of its obligations in cases due to force majeure events, as well as in cases where the defect is the result of the Student's own intentional act or omission or a third party's, which is outside the Business's sphere of influence.

6.2. Commercial Guarantee

In addition to the aforementioned legal guarantee provided by our Store, the manufacturer or the representative (importer) of the product may, on a case-by-case basis, provide a written guarantee (commercial guarantee). If the customer wants to invoke their rights under the manufacturer's guarantee, they can contact the manufacturer directly or consult the guarantee documents found within the product packaging.

7. Dispute Resolution - Applicable Law - Jurisdiction - Amendment of Terms

The applicable law is Greek law and the competent courts for the judicial resolution of any disputes arising from these terms are the courts of Athens. In case the Student resides in a location where there are more favorable mandatory law provisions applicable to them compared to the provisions of Greek law, the more favorable provisions will apply.

For the out-of-court resolution of the dispute, the Student may contact the competent bodies for the out-of-court settlement of consumer disputes, such as the Consumer Ombudsman (http://www.synigoroskatanaloti.gr/, Leof. Alexandras 144, 114 71, Athens, tel.: +30 2106460734, fax: +30 2106460414) and the Consumer Dispute Resolution Committees (Article 11 of Law 2251/1994) located in the local municipalities of the country.

Out-of-court dispute resolution can also be achieved through the European Online Dispute Resolution platform, which is available at https://ec.europa.eu/consumers/odr.

The provisions of consumer protection law, as well as the present clause, govern transactions only with natural persons who transact for reasons not related to their commercial, industrial, entrepreneurial, or professional activities.

These terms may be amended due to changes in the applicable legislation or the Business's practices. The amended terms will apply from the date of publication on the Store's website
