The sounds are recordings bundled in the App, so they should play without an internet connection. Volume and notification settings are the usual cause. Check these in order:

1. Make sure your phone is not on silent or vibrate. In the App's Settings → sound settings you can turn on playing sound in silent or vibrate mode.
2. Turn up the media volume specifically. Press a volume key and check the "Media" slider — raising only the ringtone volume will not help. The sound settings also let you play sound when media volume is 0.
3. Turn off Do Not Disturb if it is on.
4. If earphones or a Bluetooth speaker are connected, the sound may be going there. Disconnect them and try again.
5. Sound may be skipped or delayed during a phone call. On the Home screen, check that detection is on and that the delivery app is among your chosen apps.
6. An app reopened during a block goes silently back to the home screen — that is expected.
7. Check in the voice list that the voice whose turn it is has not been switched off (at least one voice must stay on).
8. If it still fails, email us with your device model and Android version.

Some manufacturers (Samsung, Xiaomi, OPPO, vivo and others) kill background services to save battery. These steps fix it in most cases:

1. Android Settings → Accessibility → turn Hey Spike back on.
2. Settings → Apps → Hey Spike → Battery → choose "Unrestricted" or "Don't optimise".
3. Lock (pin) Hey Spike in the recent-apps list so it is not swiped away automatically.
4. On Samsung devices: Settings → Battery and device care → Battery → Background usage limits, and remove Hey Spike from "Sleeping apps" and "Deep sleeping apps".
5. After a reboot, check the permission again — some devices disable accessibility services on restart.

For reference, the accessibility service reads only the package name of the app in front; it never reads on-screen text, conversations, what you type, or notification contents. See Privacy Policy, section 1.

Known delivery apps found on your phone are suggested first. If yours is missing, use "Find in installed apps" (설치된 앱에서 찾기) on the app-picking screen to add any other installed app. Phone, messaging, contacts, Settings and package-installer apps cannot be picked.

The names of the apps you choose are used on your device only and are never sent to a server.

• Sending you home works only if you turned on "Send Home after 1 minute" on the main screen (off by default). Accessibility must be connected and detection on.
• The action sends you to the home screen. It does not force-stop the target app or stop playback, so apps with background playback may keep making sound. It may not work on some devices or Android versions. During a phone call it waits until the call ends, and while only a VoIP call is active it waits at most 2 minutes.
• If you also turned on "Keep it closed afterwards", reopening a chosen app during the block time you picked (15 minutes, 30 minutes, 1, 4, 12 or 24 hours) silently sends you back home. Tap "Unblock" (막기 풀기) for an app on the blocked card on the main screen to lift it at once; it also ends by itself when the time is up.
• To stop everything, switch detection off on the main screen or turn the service off in Android Settings → Accessibility.

See the safety notice in Terms, section 2.

Voice packs (KRW 1,500 each, KRW 3,300 for the three-pack bundle) are Google Play in-app products. They are not subscriptions: you buy once and keep them.

1. Make sure you are signed in to Google Play with the same Google account you bought with.
2. In the App open the sound-pack store and tap "Restore purchases" (구매 복원). This also works on a new phone or after reinstalling; the App checks automatically at start-up, too.
3. Voices from a pack you own are added to the rotation automatically, and each can be switched on or off in the voice list.
4. You need an internet connection to load your purchases from Google Play. If it still fails, email us with your Google Play order number.

Refunds follow the Google Play refund policy and are requested in Google Play → Payments & subscriptions → Budget & order history. A refunded pack locks again at the next check. If you have trouble, email us with your order number.

From Season 2 the App has no accounts.

Records on this device
App → Settings → "이 기기 기록 지우기" (Erase this device's records). This clears usage history (opens, time spent, times scolded), the diagnostic log, unsent statistics and the install ID used for anonymous statistics. To remove your chosen apps and settings too, uninstall the App or clear its data in Android Settings → Apps → Hey Spike → Storage. (Usage records are kept for at most 90 days or 2,000 records anyway.)

Anonymous statistics on the server
They are stored under the install ID only and are not linked to any person, so they cannot be picked out and deleted on request. Turning "익명 사용 통계 보내기" (Send anonymous usage statistics) off or erasing records discards the ID on your phone so later statistics are not linked to earlier ones, and server statistics are deleted automatically after 180 days.

An account from an earlier version
Accounts and server data created by signing in with an earlier version (0.4.x or older) can be deleted as described on the account and data deletion page: email [email protected] from your registered address with the subject "야 정신차려 계정 삭제 요청" (Hey Spike account deletion); after verifying your identity we complete the request and reply within 7 days.

Retention periods and exceptions are set out in Privacy Policy, section 10.

Season 2 has no subscriptions. If you paid for a Premium subscription in an earlier version, you must cancel it in Google Play yourself; uninstalling the App or deleting your account does not cancel it.

1. Open the Google Play app and tap your profile icon (top right).
2. Go to Payments & subscriptions → Subscriptions.
3. Select Hey Spike and tap Cancel subscription.

Cancel at least 24 hours before the next billing date to avoid the next charge. Refunds follow the Google Play refund policy; if you have trouble, email us with your order number.

No. The accessibility service checks only the package name of the app in front. On-screen text, messages and chats, passwords you type, taps, notification contents and screenshots are never collected, stored or transmitted, and the App never records your microphone.

The only thing sent to our server is anonymous usage statistics, which you can turn off in settings:

• A random install ID (unrelated to device identifiers or accounts) and the app version
• When a visit started or ended and how many seconds it lasted, which sound of which voice played, whether you were sent home or reopened a blocked app, settings changes, first-run setup steps, whether accessibility is connected, and voice-pack previews and completed purchases (pack ID only)
• Never the name or package name of the apps you chose, screen contents, or your name, email or phone number. Server rows are deleted automatically after 180 days.
