Lumen Trust Notes
DeepL
Translations are processed on DeepL's infrastructure; Pro plans emphasise that texts are not used to train models—still cloud-based, so Privacy is Low for free/default use and Medium-leaning only with Pro contractual assurances (scored Low for consistency with cloud-only rules). Strong free tier supports High parity. Purpose is High for accurate cross-language communication. Provenance Low. Prefer Pro for confidential documents and review DeepL's enterprise DPA.
Microsoft 365 Copilot
Copilot processes prompts and organisational content in Microsoft's cloud; enterprise controls and compliance certifications exist, but there is no local-first option for standard M365 Copilot, keeping Privacy Low. Per-seat business pricing and licence prerequisites limit access parity for individuals and small teams. Purpose is High—it meaningfully accelerates real office workflows inside apps people already use. Closed models and opaque training details keep Provenance Low. Best for Microsoft-centric orgs with clear data-governance policies.
