Lumen Trust Notes
Wispr Flow
Wispr Flow processes speech in the cloud rather than fully on-device, so data sovereignty is limited unless Privacy Mode is on and cloud sync is disabled. Enterprise customers get stronger guarantees (SOC 2 Type II, ISO 27001, enforced Privacy Mode, SSO). The free tier and broad device support improve access, but unlimited dictation requires a paid plan. Suitable for everyday writing and coding workflows; treat sensitive dictation like any cloud voice service and enable Privacy Mode for confidential content.
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.
