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.
Google Gemini
Gemini runs fully in Google's cloud with no local or self-hosted option for the consumer and Workspace products, so data sovereignty is Low. Google offers a genuinely usable free tier and broad accessibility, supporting High parity, while the product's clear productivity mission inside Workspace earns High purpose. Closed models and limited training-data transparency keep Provenance Low. Strong for Google-centric workflows; treat sensitive data under your organisation's Google Workspace and AI data-processing settings.
