Safety guide

AI coding tools and data privacy

Identify what development data is shared, retained, trained on, and accessible before enabling a tool.

Short answer

What to do

Review privacy at the data-flow level: what is collected, where it is processed, how long it is retained, whether it trains models, who can access it, and how deletion works. Marketing labels alone are insufficient.

Inventory the data

Include prompts, source files, repository metadata, terminal output, diagnostics, chat history, user identity, telemetry, and feedback. Classify whether each type may contain secrets, customer data, personal data, or protected intellectual property.

Validate controls and contracts

Check default and configurable retention, training use, subprocessors, processing locations, encryption, access logs, deletion, and enterprise agreements. Confirm whether local or self-hosted modes still call external services.

Control day-to-day use

Create rules for allowed repositories and data classes. Configure ignore files and organization policies, but test them: an exclusion feature is useful only if it covers chat, indexing, agent tools, and diagnostics consistently.

Practical checklist

Data types inventoried
Retention known
Training use confirmed
Subprocessors reviewed
Deletion tested
Repository policy enforced
