Cancellation and Refund Policy

1. Hosting plans

USD prices are references. Subscriptions renew in the fixed RUB amount shown before you agree; the USD charge on your card may vary with your bank’s exchange rate.

The checkout requires explicit consent to automatic renewal. Visiting this page does not create a payment or authorize a charge. Existing one-time annual purchases keep their original terms and have no automatic renewal.

2. Stop future subscription renewal

Request cancellation of future monthly or annual subscription renewal using the subscription controls in your account or email support@dia.best from your account email. Cancellation prevents new automatic renewals and preserves access until the end of the paid period. Ask for a refund explicitly when that is also requested. If a bank request was already in progress, support will examine its timing and outcome.

3. Activation failure, duplicate or incorrect charges

A confirmed duplicate or incorrect charge is corrected. If paid hosting cannot be activated because of a failure attributable to Dia.best, you may request a full refund for the unprovided service. If a service period is interrupted or cannot be completed, contact support for correction or a refund appropriate to the unprovided service and applicable law.

4. Consumer withdrawal and termination rights

Where applicable consumer law grants a withdrawal or cooling-off period, those rights apply in addition to this policy. For consumers entitled to the EU/EEA statutory right of withdrawal for a distance service contract, the usual period is 14 days from conclusion of the contract. Merely activating ongoing hosting does not by itself mean that a full month or year of service has been supplied or that you waive all withdrawal rights.

If you expressly requested service to start during a statutory withdrawal period, only charges permitted by the applicable law for service actually supplied may be deducted. We do not require a blanket waiver of consumer rights to use this service. A request outside a statutory period is reviewed according to the service provided, the circumstances and applicable law.

When a statutory withdrawal refund is due, it will be made without undue delay and within the applicable legal deadline (normally no later than 14 days after receipt of the withdrawal notice for eligible EU/EEA consumers). The same payment method will be used unless another method is expressly agreed without an additional charge.

5. AI actions and promotional credit

AI-balance top-ups are one-time payments without automatic renewal and do not purchase a hosting subscription. Report an undelivered balance top-up, a duplicate or incorrect payment, or an undelivered, duplicate or incorrect AI charge to support. Successfully supplied AI actions are reviewed according to applicable law and the actual service delivered; a general label of “digital service” does not remove mandatory rights. Promotional credits are not a separate cash payout. Any adjustment of credits after a refund must be explained and must not reduce a refund required by law or affect unrelated paid balances.

6. Send a request

Email support@dia.best with your account email, order or payment reference if available, the plan, payment date and your request. Do not send a full card number, CVV, password or authentication code. Approved refunds are returned through the original payment method where possible. We will state the refund amount and any permitted deduction; processing by a bank or payment provider may take additional time. Statutory deadlines take priority.

Provider details: Contacts. Contract terms: Terms of Use.

7. Optional withdrawal notice

You may use this notice, but any clear statement of withdrawal is sufficient:

To: Individual Entrepreneur Dmitrii Vladimirovich Polianinov, Russian Federation; INN 501208561949; OGRNIP 307501231000027. Send by email to support@dia.best.
