All prices are set and displayed in Euros (EUR). EUR is the primary and reference currency for all Hexanai services.
At checkout, you may select your preferred payment currency. The EUR price is converted at the current exchange rate at the moment of transaction.

All other fiat currencies (CAD, AUD, JPY, BRL, MXN, INR, etc.): A 5% currency processing fee is added at checkout.
Cryptocurrency payments: A 7% processing fee is added at checkout, covering network fees and settlement variance.
The processing fee percentage, the fee amount, and the total charged are clearly displayed on your invoice.
The exact amount charged is calculated and shown at checkout before you confirm payment.
Digital Services are VAT exempt, except final consumers within the EU.
Approximate converted values shown on the website are indicative only. The exact charge is calculated at the moment of transaction.

Fiat currencies other than EUR, USD, GBP or CHF: +5% processing fee.
This fee covers international banking processing costs, correspondent bank fees, and exchange rate settlement variance (typically 1-3 business days).
Cryptocurrency payments: +7% processing fee.
The 7% fee covers blockchain network fees, volatility risk during settlement, and conversion to fiat at the time of receipt.
The fee is shown at checkout before confirmation and itemised on your invoice.

Refunds are available only within the first 14 days from the date of purchase.
If a refund is requested within the 14-day window, only the unused value calculated from the date of the refund request to the end of the 14-day period is eligible for reimbursement.
After the 14-day period, all sales are final and non-refundable.
All refund requests must be submitted in writing to hexanai@pm.me, including your account email, subscription details, and reason for refund.
Refund processing takes 2 to 4 weeks after approval. We are a small team and process requests in order of receipt.
No partial refunds are provided for unused portions of your subscription outside the first 14 days.

You may choose not to renew your subscription.
Cancellation mid-subscription is not available as an option — subscriptions run for their full purchased duration.
If you request a refund within the 14-day window, the refundable amount corresponds to the value of the remaining days between the refund request date and the end of the 14-day period.
Data retention after subscription expiry is subject to our Data Protection policy.

All transactions are protected with industry-standard SSL/TLS encryption for all payment communications.
Two-factor authentication is available and recommended for additional account security.
We monitor all transactions for fraudulent activity to protect our customers.
