Lumen Trust Notes
ChatGPT
ChatGPT is fully cloud-based with no local processing; all inputs are handled on OpenAI servers, making data sovereignty low. Its mission centres on broadly beneficial AI, with transparent safety research and a strong free tier that democratises access. Recommended for general productivity, writing, and research — avoid sharing sensitive PII or confidential commercial data.
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.
