By using Drift you agree to these terms. They're short on purpose.
Drift is a private sleep journal and educational tool. It teaches published cognitive-behavioural-therapy-for-insomnia (CBT-I) techniques — sleep-window planning, stimulus control, and sleep-education content — as a guided plan you follow yourself. Drift is not a medical device, not a diagnosis, and not a substitute for clinical care. Reducing time in bed can increase daytime sleepiness: never drive or operate machinery while drowsy. If your insomnia is severe, persistent, or accompanied by daytime safety risk, please consult a clinician.
One account per person, 18 or over. Sign in with Apple, or use the private on-device journal without an account. Don't try to elicit medical advice from the coach — it is educational only and will decline.
Drift Pro is $9.99/month or $59.99/year, with a 7-day free trial on the annual plan. Subscriptions auto-renew via Apple unless cancelled at least 24 hours before the period ends. Manage or cancel any time: in-app via Settings → Manage subscription, or iOS Settings → Apple ID → Subscriptions. Subscribers who joined at an earlier price keep that price.
Apple controls refunds. Visit reportaproblem.apple.com.
The free tier includes the morning diary, the sleep-efficiency trend, stimulus-control education, and your first computed sleep window including your first weekly review. Pro continues the weekly reviews and adds the coach, sound analysis, the pink-noise engine, and sleep stories. We may rate-limit obvious abuse of the coach endpoint.
We may update these terms; the date at the top reflects the most recent change. Material changes to billing or data handling will be surfaced in-app before they take effect.
