Terms of Service

Last updated: 10 September 2026

These Terms of Service (the “Terms”) govern your access to and use of the Vaulta backup service, including the web console, the REST API and the Vaulta agent software (together, the “Service”). The Service is operated by Shanghai Wavetop Information Technology Co., Ltd, registered at Room 22301-186, Building 14, No. 498 Guoshoujing Road, Shanghai Pilot Free Trade Zone, China (“Vaulta”, “we”, “us”).

By creating an account or installing the agent you agree to these Terms. If you are entering into these Terms on behalf of a company, you confirm you have authority to bind that company.

1. What the Service does

Vaulta schedules and orchestrates backups from machines you control to object storage you control. We provide the control plane, the agent software, the scheduling, the client-side encryption, and — on paid plans — automated restore verification.

We do not store your backup data. Backup content is written directly from your machines to storage buckets held under your own cloud provider account. Your contractual relationship with that storage provider is separate from these Terms, and you are responsible for its cost, configuration and availability.

2. Accounts

You must provide an accurate email address and keep your credentials secure. You are responsible for all activity under your account. Notify us promptly at [email protected] if you believe your account has been compromised.

Accounts are for organisations and individuals aged 18 or over. One person or organisation may not operate multiple free accounts to circumvent plan limits.

3. Encryption keys are yours alone

Backup content is encrypted on your machine before upload, using a key derived from a BIP39 recovery mnemonic generated on your machine. That mnemonic is never transmitted to us and we cannot recover it.

If you lose the mnemonic and lose the machines holding it, your backups are permanently unreadable — by you, by us, and by anyone else. This is a deliberate property of the design, not a defect. You are solely responsible for storing your recovery mnemonic safely.

4. Plans, billing and cancellation

Paid plans are billed in advance on a monthly or annual basis. Annual plans are billed as ten months. Payments are processed by our authorised payment provider, which acts as merchant of record and is named on your invoice; applicable VAT, GST and sales taxes are calculated and remitted by that provider.

You may cancel at any time from the billing page in the web console. Cancellation takes effect at the end of the current billing period; the Service remains available until then. We do not charge cancellation fees.

Refunds are governed by our Refund Policy, which forms part of these Terms.

We may change prices. Existing subscribers will be given at least 30 days’ notice by email before a price change takes effect on their subscription, and may cancel before it applies.

5. Plan limits

Each plan includes a stated number of Assets. One Asset is one machine running one Vaulta agent; everything backed up on that machine is included in that Asset. If you exceed your plan limit, existing protected machines continue to work and new ones are blocked until you upgrade or remove a machine.

6. Storage backend limitations

Vaulta writes to S3-compatible object storage. Capabilities differ between providers, and we publish what we have actually tested on our home page rather than what a vendor’s documentation claims.

In particular, automatic space reclamation is not available on Backblaze B2, because its S3-compatible API does not implement the atomic conditional write our maintenance lock depends on. On B2, expired snapshots are marked but their storage is not released. You are responsible for reviewing these limitations before choosing a backend.

7. Acceptable use

You agree not to:

• use the Service to store or transmit unlawful content, or content you have no right to copy;
• attempt to gain unauthorised access to the Service, other accounts, or the underlying infrastructure;
• probe, scan or load-test the Service without our prior written consent;
• resell or white-label the Service without a written agreement with us;
• use the Service in a way that degrades it for other customers.

We may suspend an account that we reasonably believe is engaged in the above, and will tell you why unless prohibited by law.

8. Availability and support

We aim to keep the Service continuously available, but we do not offer a contractual uptime commitment on the plans described on this website. Support is provided by email at the response targets stated on the pricing page; those targets are goals, not guarantees.

Scheduled maintenance that we expect to interrupt the Service will be announced by email in advance where practical.

9. Your responsibilities

Backup is a shared responsibility. You are responsible for choosing what to back up, verifying that restores meet your recovery objectives, retaining your recovery mnemonic, and maintaining your storage provider account. We strongly recommend performing a restore test before relying on Vaulta for anything critical, and paid plans automate exactly that.

10. Warranties and liability

The Service is provided “as is”. To the maximum extent permitted by law we disclaim all implied warranties, including merchantability, fitness for a particular purpose and non-infringement.

To the maximum extent permitted by law, our total aggregate liability arising out of or relating to the Service is limited to the amount you paid us in the twelve months preceding the event giving rise to the claim. We are not liable for indirect, incidental, special or consequential damages, or for loss of data, profits or business.

Nothing in these Terms excludes liability that cannot lawfully be excluded, including for death or personal injury caused by negligence, or for fraud.

11. Termination

You may stop using the Service and delete your account at any time. We may terminate or suspend your account for material breach of these Terms, or on 30 days’ notice for any reason.

On termination we delete your account metadata within 30 days. Your backup data is not affected — it remains in your own storage bucket, and it remains restorable using the documented storage format and your recovery mnemonic.

12. Changes to these Terms

We may update these Terms. Material changes will be announced by email at least 30 days before they take effect. Continuing to use the Service after that date constitutes acceptance.

13. Governing law

These Terms are governed by the laws of the People’s Republic of China, and the competent courts of Shanghai have jurisdiction, without prejudice to mandatory consumer protections in your country of residence.
