Security & Compliance
Your data, our posture
SubjectLab processes the inputs you submit for analysis. This page states, plainly, what we handle and what we do not claim.
What we handle
campaign briefs you paste to score subject variants.
Data handling commitments
- Submissions run the product pipeline and are retained only as long as needed for your audit log (paid tiers) or until you delete the run.
- We apply access controls consistent with GDPR Art. 32 (security of processing) where personal data is processed.
- BYOK keys (Enterprise), when offered, are stored server-side only and never exposed to the browser.
Honesty rule: SubjectLab scores subjects. It does not guarantee opens, clicks, or deliverability.
Our compliance posture
- SubjectLab is decision-support, not a law firm, clinic, or certified auditor.
- For binding advice, consult a qualified professional in the relevant domain.
Subprocessors & payments
- Payments are processed by Waffo Pancake (merchant of record).
- See Privacy and Terms for full terms.
