PRIVACY, COMPLIANCE SUPPORT & DATA RESIDENCY
Identify sensitive fields in your instrumentation. Redact their values before recording, use opaque application tokens where appropriate, and investigate locally with the exact build catalog. Keep data handling explicit from capture to collection.
Sarvalekha provides technical building blocks for your compliance program. Applicability, lawful transfers, deployment controls, and certification depend on your system and obligations. This guide is a technical mapping, not legal advice or a certification claim.
Explore the protection featuresCONTROL WHAT YOU RECORD
For sensitive telemetry, the first decision is whether the value needs to be recorded at all. The current C++ foundation makes that decision explicit in application instrumentation.
Developers mark PII, confidential data, credentials, and regulated fields. Build-time policy checks can reject disallowed capture or narrow declared destinations.
This is developer-declared classification. Automatic discovery of PII in arbitrary strings, files, or crash dumps is not implemented.
Redacted capture stores no original value bytes for that field in the event. Investigators see a redaction marker while retaining the surrounding diagnostic context.
This protects that capture path. It does not remove copies elsewhere in application memory, other logs, or a full-memory crash dump.
Record an opaque token supplied by your application and keep any lookup mapping under separate access controls. The application is responsible for generating a suitable token.
Keyed-hash capture requires a working key-provider integration; the current minimal profile reports unavailable without exposing the input. Neither tokenization nor hashing automatically establishes legal anonymisation.
Read locally retained logs with their matching catalogs. The Helper can collect locally with uploads disabled, or send completed native files to an explicitly configured server.
Local collection supports a residency strategy when the host, storage, backups, and access meet your policy. Current destination declarations do not provide a country-aware transfer firewall.
MAP CONTROLS TO YOUR REQUIREMENTS
Data residency concerns location. Transfer restrictions also consider recipients and access. Security frameworks assess a broader system. These requirements can overlap, but one product setting does not satisfy them all.
| Framework and source | What it addresses | Sarvalekha contribution | Deployment and qualification |
|---|---|---|---|
| EU GDPR / German DSGVO | Personal-data protection and transfers outside the EEA. Lawful transfer mechanisms can include adequacy decisions or appropriate safeguards; this is not a general Germany-only storage rule. | Classify sensitive fields, redact values before recording, and use application-supplied tokens to reduce identifying information in telemetry. Local investigation can avoid sending logs to a remote service. | Determine lawful processing and transfer grounds, recipient access, contracts, retention, and any required transfer assessment. Tokens do not automatically make data anonymous. |
| Germany: BDSG and sector-specific rules | The BDSG supplements the applicable data-protection framework. Sector rules can add location conditions: SGB X section 80 restricts where commissioned processing of social data may occur, while allowing specified locations outside Germany. | Use local logs and matching catalogs, developer-declared sensitive-field policies, and separately controlled artifacts to design a deployment around the permitted processing boundary. | Identify the actual sector and contract requirements. Verify hosting, support access, backups, and all hierarchy nodes. Sarvalekha does not determine a server country or enforce German legal eligibility. |
| UK GDPR international transfers | Restricted transfers to separate organisations outside the UK need an applicable transfer mechanism. Making data accessible can matter even without moving its storage location. | Reduce recorded identifiers through classification and redaction. Keep token mappings separately controlled and choose local investigation where remote access is unnecessary. | Assess the recipient and processing arrangement, applicable adequacy or safeguards, and transfer risk. Pseudonymised data may still be personal data. |
| US DoD: DFARS 252.239-7010 | For covered cloud-service contracts, Government data outside DoD premises must be maintained in the United States or outlying areas unless the contracting officer authorizes another location in writing. | Local capture, an optional uploader, explicit server configuration, and separate artifact access provide building blocks for an approved deployment. Redact unnecessary sensitive fields at capture. | Qualify the complete hosting environment, locations, access, incident handling, and contract controls. Destination labels are not country-level enforcement and redaction does not waive contract obligations. |
| US ITAR export controls | Controlled technical data is broader than PII. Releasing it to a foreign person can be an export even inside the United States, subject to the applicable regulatory exceptions. | Remove logging-only descriptions from shipped executables, retain catalogs separately, and omit sensitive runtime values. Local investigation can reduce unnecessary artifact distribution. | Determine export classification, recipients, authorizations, and applicable exceptions. Catalogs, source, symbols, dumps, and logs may themselves be controlled; metadata removal does not authorize an export. |
| US federal and defense: FedRAMP / CMMC | FedRAMP addresses assessment and authorization of in-scope federal cloud services. CMMC assesses protection of federal contract information and controlled unclassified information in the defense supply chain. | Sensitive-field minimization and scoped server access can contribute to a system security design. Preserve exact build artifacts to explain the telemetry being collected. | Assess the complete system and required controls. These features do not establish FedRAMP or CMMC certification, authorization, or satisfaction of NIST requirements. Agency and contract conditions define the deployment scope. |
| US DOJ Data Security Program / EO 14117 | Prohibits or restricts certain transactions giving countries of concern or covered persons access to government-related data or bulk US sensitive personal data. It is not a blanket ban on all international transfers. | Avoid recording unnecessary sensitive fields and limit who receives retained logs and related artifacts. Redaction reduces the original values captured in events. | Evaluate data categories, thresholds, recipients, transactions, and program duties. The bulk-data definition can cover anonymized, pseudonymized, de-identified, or encrypted data; transformation alone is not an exemption. |
| US healthcare: HIPAA | Protects health information in covered arrangements. HIPAA does not categorically forbid overseas cloud storage; applicable agreements and privacy/security obligations still apply. | Classify health-related fields and redact unnecessary identifiers to reduce sensitive diagnostic content. Restrict log and artifact access within the chosen deployment. | Address applicable business associate agreements, risk analysis, safeguards, and retention. Field redaction alone does not establish HIPAA de-identification under Safe Harbor or Expert Determination. |
DESIGN THE WHOLE DATA PATH
Include the machines and people that can access the evidence. Review remote support, backups, failover, catalog hierarchy nodes, and every exported artifact as part of the same deployment.
Classify fields and redact unnecessary values before serialization. Keep sensitive values out of static message text, source paths, and catalogs as well as runtime fields.
Use approved local storage or explicitly configured collection endpoints. Control machine access, network egress, support access, and backup locations. The native-file uploader does not provide a per-field sanitization pass.
Review logs, catalogs, source, symbols, and dumps separately. Configure permitted recipients and required encryption; document retention, deletion, key custody, and the lawful basis for any transfer.
An application can record a redacted field or an approved opaque token for diagnostics while keeping the original in its own controlled system. Verify the full outgoing artifact: other values, correlation context, and metadata can still identify people. Binary encoding and metadata removal do not encrypt runtime values.
