Terms of Service

1. Agreement

These terms govern your use of Nevastack services, operated by Nevastack (company registration no. HE 495245, VAT CY60379604J) from Alexandrou Papadiamanti 1, 6035 Larnaca, Cyprus. By creating an account or placing an order you accept them. Enterprise customers may sign a separate master agreement, which prevails where it conflicts with this page.

2. The services

We provide GPU and bare-metal compute, managed model adaptation (RAG, LoRA, fine-tuning, training) and OpenAI-compatible inference endpoints in EU regions.

Capacity is subject to availability in the region you choose. Bare-metal reservations start once we confirm capacity in writing.

3. Your account

You are responsible for keeping credentials and API keys confidential and for all activity under your account. Keys can be scoped and revoked in the console; revoke immediately if a key is exposed.

You must be at least 18 and, where you act for a company, authorised to bind it.

4. Fees, payment and taxes

Compute is billed hourly, plans monthly, and inference by metered usage. Prices are in EUR and exclude VAT unless stated otherwise.

We accept card, sepa, invoice. Invoices on annual contracts are payable within 30 days. Late payment may lead to suspension after written notice.

• Hourly instances bill from provisioning until you destroy them, whether or not they are busy.
• Paused instances stop compute charges; attached storage and snapshots continue to meter.
• Reserved capacity and bare metal have a one-month minimum term.

5. Pilot guarantee

30-day pilot guarantee: if your first project does not hit the evaluation targets we agree in writing, you do not pay the setup fee.

The guarantee applies to the first project on an account, requires an evaluation set agreed in writing before work starts, and covers the setup fee only — consumed compute is still billed.

6. Acceptable use

You may not use the services to:

• Break the law, infringe intellectual property, or process data you have no right to process.
• Attack, scan or overload our infrastructure or a third party's, or mine cryptocurrency.
• Generate content that sexualises minors, incites violence, or is designed to deceive people about its origin in a harmful way.
• Circumvent rate limits, quotas or isolation between accounts.

7. Your data and ours

You keep all rights to content you upload and to artefacts produced from it, including fine-tuned adapters and checkpoints. We claim no licence beyond what is needed to run the service for you.

We keep all rights to the platform itself. Nothing here transfers our software, documentation or trademarks.

8. Availability and support

We aim for continuous availability and staff support 24/7; sales and billing follow CET business hours. Planned maintenance is announced in advance where possible.

Service credits and response-time commitments, where offered, are set out in your contract. Without a signed SLA the services are provided on a commercially reasonable basis.

9. Liability

Neither party excludes liability for fraud, death or personal injury caused by negligence, or anything else that cannot be excluded by law.

Otherwise, and to the extent permitted by law, neither party is liable for indirect or consequential loss, and each party's total liability is capped at the fees paid in the twelve months before the claim.

You are responsible for keeping your own backups of data you upload.

10. Termination

You can close your account at any time; charges already incurred remain payable. We may suspend or terminate for material breach, unpaid invoices after notice, or unlawful use.

On termination we delete customer content according to the window in your DPA. Export your artefacts before you close the account.

11. Changes and governing law

We may update these terms; material changes are notified by email at least 30 days before they take effect. Continued use after that date means acceptance.

These terms are governed by the laws of the Republic of Cyprus, and the courts of Larnaca have jurisdiction, without prejudice to mandatory consumer protections in your country of residence.
