No, Luminastack doesn't offer a free tier. Plans start at £19/month, or £182.40/year if billed annually (a saving of roughly £45.60 versus paying monthly). You can try the platform risk-free through this paid entry tier before scaling up to higher storage plans.

Storage is billed on a pay-as-you-go basis, calculated from your average daily usage over the billing cycle and charged per GB (or TB) stored. Bandwidth/egress and API requests are metered separately and itemized on your invoice, so you only pay for what you actually use — with no long-term contracts required.

Yes. Customer-managed encryption keys (BYOK) are supported for data at rest, letting you retain full control over key generation, rotation, and revocation through your own key management system (e.g., AWS KMS, HashiCorp Vault, or an on-prem HSM). If a key is revoked, the associated data becomes immediately inaccessible, even to us.

Yes. Luminastack maintains a current SOC 2 Type II report covering security, availability, and confidentiality controls, renewed annually through an independent third-party audit. The report is available on request under NDA for customers and prospects.

Luminastack guarantees 99.9% monthly uptime for core storage and API services. If uptime falls below that threshold in any billing month, affected customers receive service credits on a sliding scale based on the severity of the shortfall, as detailed in the SLA terms.
