Data & security

The short version: your code stays in your repos, your credentials stay in your systems, and nothing is retained after handoff.

#The principles

  • NDA-friendly. Happy to sign yours before anything sensitive changes hands.
  • Scoped access. I take the least access needed for the engagement, and it’s revoked at the end.
  • Your systems of record. Code stays in your repos; credentials stay in your secret manager; automations run in your accounts.
  • Nothing retained. After handoff I don’t keep copies of your data or code.
  • Evaluation data. Golden sets and eval fixtures live in your repo, versioned next to the code — you own them.

#Where your data actually lives

The design goal is that sensitive material never leaves systems you control. Concretely, by asset class:

AssetWhere it livesMy access
Source codeYour Git hostLeast-privilege collaborator, revoked at handoff
Secrets / credentialsYour secret manager (Vault, Doppler, cloud KMS)Never copied locally; referenced, not held
Production dataYour infrastructureScoped, read-where-possible; no bulk export
Eval / golden setsYour repo, versionedYou own them — they ship with the code
LLM prompt dataYour chosen providerProvider chosen for a no-train data policy; documented per engagement
On LLM providers specifically: the model vendor is selected so that your prompt and completion data is not used to train anyone’s model, and the exact provider + data-processing terms are named in the engagement’s SOW — not left vague.

#Retention & deletion

After handoff I remove local clones, revoke every access grant, and delete any transient working copies. What remains is entirely in your systems: the code in your repo, the runbook in your docs, and the eval fixtures versioned next to your tests. There is no Sage-Ideas-side copy of your data to breach.
