We sell subscriptions to the contents of our website.

You pay for the subscription on a recurring basis. By subscribing to the product you authorize us to charge your credit/debit card whenever the subscription is due for renewal.




You can cancel your subscription at any time for any reason. After your subscription is cancelled no further payments will be made. However, there will not be any full or partial refunds for any reason of the payments already made.




If you acquire new users who subscribe to www.lenaia.com and www.chi.guru, you will get a 20% discount on your next payment for every user, which has submitted your reference-number when signing up, and which will be subscribed at the moment that your next payment is made. If your total discount is 100% or more, your next tacit renewal will be free. If your total discount exceeds 100% of the monthly subscription price, you will not get any payment from us. If you cancel your subscription, all your discounts will be invalidated.
