Terms of Use

Effective date: 17 September 2026

1.The app

SleepTight ("the app") is a sleep tracking application for iOS and Android that runs entirely on your phone. It is provided by SleepTight ("we", "us"). It plays sleep sounds, listens for loud sounds through the snore and scream detectors, shows a nightstand clock, and produces a morning report, trends, and logs from what it measured and estimated overnight.

2.License

When you obtain the app through the Apple App Store or Google Play, we grant you a personal, non-exclusive, non-transferable, revocable license to install and use the app on devices you own or control, for your personal, non-commercial use, in accordance with these terms and the applicable store's terms of service.

3.One-time purchase

The app is sold as a one-time purchase of $9.99. There is no subscription, no account, and no in-app purchase needed to unlock any feature. Payments, refunds, and billing are handled by Apple or Google under their policies. Any refund request is subject to the rules of the store where you bought the app. A purchase on one store does not include the app on the other.

4.Not medical advice

The app is not a medical device and does not provide medical advice. Time in bed and consistency are measured from when you start and end a night. Sleep onset, awakenings, efficiency, disturbance, and the score are estimates derived from sound and motion, and the app labels them as estimates. A phone cannot see brain activity, so the app provides no sleep-stage information of any kind and makes no claim about any stage of sleep.

The snore and scream detectors respond to sound level. They can miss events and they can trigger falsely, for example on rain sounds, traffic, a partner, or a pet. The night-terror log is a diary that you keep; the app links it to loud events but does not interpret them. Nothing in the app diagnoses, screens for, or monitors sleep apnoea, parasomnias, or any other condition.

Do not use the app as a baby monitor, a medical alarm, or a safety device. Do not rely on it for any medical decision. If you are concerned about your sleep or someone else's, consult a qualified clinician. You use the app and its estimates at your own risk.

5.Alarm and reminders

The alarm, bedtime reminders, and wind-down prompts depend on your phone's notification and audio settings, on Focus and Do Not Disturb modes, on battery and power management, and on the operating system keeping the app alive overnight. Any of these can silence or delay them. Do not rely on the app as your only alarm when waking on time matters. Set a second alarm on the phone's own clock or another device.

6.Recordings

When a detector is on, the app can save short audio clips on your phone. You are responsible for complying with the laws that apply where you are when recording audio, including any duty to tell, or get consent from, other people who share the room. You are also responsible for anything you choose to share: once you export a clip, that copy is outside the app and outside its encryption.

7.Your data and your responsibility

Your data is stored only on your phone. If you turn on the optional lock, it is protected by a PIN, and optionally biometrics, that you set. You are responsible for remembering your PIN and any backup passphrase. Because we never receive your data, your PIN, or your passphrase, we cannot recover your data, reset your PIN, or open a backup for you. We recommend creating an encrypted backup and keeping its passphrase somewhere safe.

8.Acceptable use

You agree not to reverse engineer, decompile, or attempt to extract the source code of the app except to the extent this restriction is prohibited by law; not to use the app to record anyone unlawfully; and not to use the app in any unlawful way or to infringe the rights of others.

9.Intellectual property

The app, its name, logo, design, and content are owned by us and protected by intellectual property laws. These terms do not grant you any rights in our trademarks or branding.

The app includes third-party audio. The rain loops are used under the Pixabay Content License and CC0, and the white, pink, and brown noise is generated by the app. Credits for each recording are listed in the app's About screen. The DSEG seven-segment typeface used on this website is by keshikan under the SIL Open Font License.

10.Warranty disclaimer

The app is provided "as is" and "as available", without warranties of any kind, whether express or implied, including fitness for a particular purpose, accuracy, or non-infringement, to the fullest extent permitted by law. We do not warrant that the app will be uninterrupted or error-free, that the detectors will catch every event or ignore every non-event, that the alarm will sound, or that estimates will be accurate.

11.Limitation of liability

To the fullest extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, missed alarms, or missed events, arising from your use of or inability to use the app. Where liability cannot be excluded, it is limited to the amount you paid for the app.

12.Changes

We may update these terms from time to time. Material changes will be posted on this page with a new effective date. Continued use of the app after a change means you accept the updated terms.
