Operator-managed.
Accountable by design.

Stoneline Data is a managed data custody service built on the principle that storage without accountability is just disk space. We pair enterprise-grade cloud infrastructure with named, documented human oversight.

Why operator-managed custody produces better outcomes

Large-scale automated storage platforms are optimized for volume, not visibility. When something goes wrong, you interact with a ticket system, not a person who understands your data.

Stoneline Data operates differently. Every account is provisioned and monitored by a named operator who is responsible for your data. You know who to contact. Your custody agreement specifies exactly what that person is accountable for.

This model fits organizations and individuals for whom a data loss event carries real consequences: regulatory penalties, irreplaceable personal records, or years of creative work. When accountability matters, it needs to be explicit and documented.

Three kinds of clients. One standard of documentation.

Regulated organizations such as medical offices, law firms, and financial services providers use Stoneline Data to satisfy the documented accountability requirements of HIPAA, legal retention standards, and internal audit programs. We provide the signed agreements, access logs, and written verification records their compliance programs require.

Individuals who want a personal data lockbox use Stoneline Data to protect estate documents, financial records, family media, and other irreplaceable files under a signed custody agreement with clear terms for access and retention.

Creators, photographers, videographers, and musicians use Stoneline Data to maintain verified off-site archives of their original work, with version retention policies that ensure nothing is silently overwritten and cold archive tiering that keeps large libraries affordable over time.

We put our obligations in writing before we touch your data. Your custody agreement defines scope, encryption standard, retention schedule, and what happens when you need your data back.

You receive a monthly report confirming your backup is intact. These reports are suitable for compliance documentation. We raise any issues in writing and resolve them before your next report is due.

What guides how we operate

01
Documentation before data

We sign a custody agreement with every client before provisioning their storage. Scope, encryption standard, retention terms, and access controls are documented in writing first.

02
Verification, not assumption

We run weekly automated integrity checks to confirm your three copies match, and we report the result every month. We do not assume a backup is good; we prove it.

03
Named accountability

Every account has a named operator. You know exactly who is responsible for your data. There is no abstraction layer between you and the person who manages your custody.

04
Minimum necessary access

Your storage bucket is isolated from other client accounts. IAM permissions are scoped to the minimum required for operations. No cross-account data access is possible.

05
Transparent sub-processors

We use AWS and Google Cloud as sub-processors. Both are disclosed in your Data Processing Agreement and both maintain their own HIPAA BAA programs available to clients on request.

06
Clean offboarding

When a client leaves, we deliver their data, confirm receipt in writing, hold the data for 30 days, then delete all buckets and credentials. The paper trail closes cleanly on both sides.
