Lumen Trust Notes
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.
n8n
n8n's self-hosted option means organisations can run the entire platform on their own infrastructure with zero data leaving their environment, earning a rare High privacy score. Its fair-code open-source model, transparent codebase, and free self-hosted tier make it the most sovereignty-respecting automation platform in this directory. Strongly recommended for data-sensitive organisations, regulated industries, and any team that needs full control over automation data flows.
