VULK operates on a recurring subscription model. This page explains our no-refund stance, how cancellation works, and the statutory rights that remain unaffected.
1. All purchases are final — VULK does not provide refunds
All payments to VULK — monthly subscriptions, yearly subscriptions, and credit top-ups — are final and non-refundable. We do not provide refunds, except where a refund is required by mandatory applicable law.
The reason is straightforward and physical: credits map to real AI-inference costs we pay to upstream providers (OpenRouter, Vertex AI, OpenAI, Anthropic, xAI) the moment a generation runs. That compute is delivered to you and cannot be recovered.
Because purchases are final, no refund is issued when:
- Only some of the credits in your plan have been used — the unused balance is not refunded.
- You cancel mid-period — access continues until the end of the billing period, with no prorated refund.
- A generation produced output you didn't expect — re-running a generation uses additional credits; that is the pricing model, not a defect.
- You no longer need the service or forgot to cancel before a renewal.
2. EU 14-day withdrawal right is waived at checkout
Under Directive 2011/83/EU, EU consumers normally have a 14-day right to withdraw from a distance contract. Article 16(m) removes this right for digital content when (a) supply has begun and (b) the consumer has given prior express consent and acknowledged the loss of the right of withdrawal.
At checkout you tick a consent box that says exactly this, captured in the Stripe receipt and in our database. By completing payment you expressly consent to immediate provision of digital content and waive the 14-day right of withdrawal. After that point, no refund is available — including for unused credits or accounts that never run a generation.
This is standard SaaS practice and compliant with Article 16(m). Mandatory consumer-protection rights that cannot be waived (for example, your national chargeback rights for fraud) remain unaffected.
3. Cancel anytime to stop future renewals
You can cancel your subscription at any time in Settings → Billing. Cancellation:
- Stops future renewals — no further charges will be billed.
- Keeps your access until the end of the current billing period — paid time is not lost.
- Does not refund the current period's fee or any unused credits.
4. Unused credits
Credits are sold and consumed as part of a final purchase. Unused credits are <strong>not refundable</strong> and are not exchanged for cash. They expire at the end of their billing cycle unless your plan states otherwise.
5. Plan changes (upgrades & downgrades)
- Upgrade — billed prorated for the remainder of the current period; the higher-tier plan starts immediately.
- Downgrade — takes effect at the end of the current period; the difference is not refunded.
- Switching monthly ↔ yearly — handled the same way as upgrades / downgrades respectively, with no refund of fees already paid.
6. Billing errors & edge cases
- Duplicate charge — if Stripe shows two charges for the same plan within 24 h, contact us; we reverse the accidental duplicate after verification. This corrects a billing error and is not a refund of a valid purchase.
- Service outage exceeding the SLA — Business plan customers receive service credits per the SLA, not cash refunds.
- Account closed by us for ToS violation — no refund is issued. See Terms § 6.
- Charge dispute / chargeback — opening a chargeback automatically suspends the account. Please contact us first; we resolve most billing questions within 48 h.
7. Billing questions
For any billing question, use the contact form, select topic "Billing", and include:
- Account email
- Stripe receipt URL or last 4 digits of the card
- A short description of your question
We respond within 1 business day. Note that responding does not imply a refund will be issued — purchases are final, and we will explain your options (such as cancellation) clearly.
8. Tax and invoicing
EU VAT is applied per your billing country (EU OSS rules) and shown on every invoice. In the rare event of an approved billing-error correction, we issue a credit note that reverses the corresponding VAT. Outside the EU, sales-tax handling depends on the buyer's jurisdiction.
9. Changes to this policy
We may update this policy. Material changes are announced by email at least 14 days before they take effect. The current version always lives at /refund-policy.
