Help for Coda on Google Play. Most questions are answered below — for anything else, we read and answer every email.

• How does the program work? Coda is an 8-week routine of respiratory myofunctional exercises for the tongue, mouth, and airway, designed by ENT physicians. Each session guides you through a set of movements with a timer and a repetition count.
• How long does a session take? A few minutes. Consistency matters more than duration — the program is built around training a little every day.
• Is my training record backed up? No. It is stored only on your phone. Uninstalling the app or clearing its data erases it, and there is no sync to a new device.
• Does the app listen to me snore? No. Coda has no microphone permission and cannot record. It plays bundled audio cues during exercises; that is all the audio it touches.
• Can I start the program over? Yes — use Reset in the app. That clears your progress and streak so you can begin week one again.
• Is this a substitute for seeing a doctor? No. Coda is an exercise app, not a medical device. If you suspect sleep apnoea, have breathing pauses during sleep, or have any medical symptom, see a clinician.

Turn the daily reminder on in Settings. Android asks for notification permission at that moment — the rest of the app works normally if you decline. To change it later, use Settings inside Coda, or Android Settings → Apps → Coda → Notifications.

Coda is a paid app bought once on Google Play. There are no in-app purchases and no subscription, so there is nothing to restore and nothing to cancel.

• Reinstalling on a new phone: sign in to the Google account you bought with, then Google Play → profile icon → Manage apps & device → Library, and install Coda. You are not charged again. Your training record does not carry over — it lived on the old device.
• Order history and refunds: Google Play → profile icon → Payments & subscriptions → Budget & order history, or play.google.com/store/account. Refunds follow the Google Play refund policy.
• Redeeming a promo code: Google Play → profile icon → Payments & subscriptions → Redeem code.

• Reminders are not arriving: check that notifications are allowed in Android Settings → Apps → Coda → Notifications, and that battery optimisation is not restricting the app.
• Progress looks wrong after a reinstall: progress is stored on the device only, so a reinstall starts fresh. There is no way to recover a record from a previous install.
• The app crashes or will not open: force-stop it from Android Settings → Apps → Coda, then reopen. If it persists, email us your device model and Android version.
