Privacy Policy
Effective July 2026 · applies to the Halcyra iOS app and this website
The short version
Halcyra is local-first. Your logs, streak, triggers, money, and your "why" are stored on your device and never sent anywhere. There is no account, no ads, and your data is never sold — there's nothing to sell.
What stays on your device
Everything you enter or log: nicotine use, cravings, timestamps, triggers, costs, goals, and settings. Backups are files you create and hold yourself (for example in Files or iCloud Drive) — we never see them.
Anonymous usage (optional)
If "Share anonymous usage" is on (Settings → Usage data), we receive anonymous, behavioural events only — which screens and features get used — processed in the EU (PostHog, Frankfurt) with IP addresses discarded at ingestion. Never your logs, times, triggers, amounts, money, notes, or the nicotine product you use. Turn it off anytime; the app works identically.
Notifications
Reminders are optional, scheduled on your device, and never leave it.
Deleting your data
Settings → Delete removes every log, streak, and setting from the device immediately. Because we hold nothing, there's nothing to ask us to delete.

Not medical advice
Halcyra supports general wellness. It isn't a medical device and doesn't provide medical advice — for medical help, talk to a doctor or call 1-800-QUIT-NOW (US).
