Caffeine respects its users’ privacy. It never collects any personal information.
People often rely on Caffeine for mission-critical tasks. Because of that, the app has a mechanism for monitoring its stability and performance (e.g. crash and response rate). The data sent by Caffeine is not personalized, used exclusively for software improvement, and never shared with third parties. It cannot be used for tracking or ad purposes.
