Lumen Trust Notes
Claude
Claude is cloud-only with processing on Anthropic infrastructure; there is no self-hosted option, keeping privacy at Low. Anthropic's Constitutional AI framework and published safety research demonstrate a genuine ethical mission beyond commercial interest, earning a High Purpose score. A strong choice for teams needing thoughtful long-form analysis, but treat it like any managed cloud service with regard to sensitive data.
Grammarly
Text is sent to Grammarly's cloud for analysis; enterprise plans add stronger admin and data controls, but standard use is not local-first (Privacy Low). Free tier plus accessible Premium pricing support Medium parity. Purpose is High—clear productivity value without dark-pattern lock-in for basic writing help. Provenance Low due to closed models. Fine for everyday writing; disable or avoid on highly confidential documents unless enterprise terms and settings meet your bar.
