No account, no cloud, nothing to sell. Your data stays on your device. The only thing that leaves is anonymous diagnostics — and that's the whole story.
Last updated: 27 June 2026
Your habits, check-ins, and reminders live only on your iPhone, and reminders are scheduled locally. None of it is sent to us or anyone else, and deleting the app deletes it for good.
nag sends anonymous diagnostics via Sentry to stay stable and fast: crash reports and a sampled amount of performance and technical data — for example, spotting when the app stalls or is slow to open. It never includes your habits, notes, or any personal information, and is never used to identify or track you.
No accounts, ads, analytics, behavioural or cross-app tracking, data selling, or access to your location, contacts, photos, microphone, or camera.
