Night Window – Terms of Service
Last updated: October 2026
Welcome to Night Window (眠窗, "the app"). Please read these Terms of Service ("Terms") before using the app. By using the app you agree to these Terms. If you do not agree, please do not use the app.
1. The service
The app plays white noise and sleep sounds together with ambient scene visuals. Free content can be used without signing up. Some scenes require a membership (subscription or one-time purchase); what is included is shown on the in-app purchase screen.
The app is not a medical device and does not provide medical diagnosis, treatment or advice. Its sounds are only a relaxation and sleep aid and cannot replace professional care. If you have ongoing sleep problems or other health concerns, please see a doctor.
2. Accounts (optional)
Current version: sign-in / account features are still in development and are not yet available in the app, consistent with our Privacy Policy. This section describes the rules that will apply once accounts launch.
You can use all free features without signing up. If you choose to sign in (to sync your membership and data across devices), you agree to:
- provide a real, valid email address or phone number (or use a third-party sign-in) and keep your sign-in credentials secure;
- be responsible for all activity under your account, including purchases;
- contact us immediately if you notice unauthorized use of your account.
Except where an account is compromised because of a security flaw in the app itself, we are not liable for losses caused by someone else using your credentials. Details on linking, unlinking and deleting accounts are in the Privacy Policy.
3. Subscriptions, one-time purchases and billing
The app offers the following paid plans. Actual prices are those shown on the in-app purchase screen at the time of purchase and may vary by region and promotion:
- Monthly subscription — renews automatically every month; cancel anytime.
- Yearly subscription — renews automatically every year; cancel anytime. It may include a free trial (length shown on the purchase screen).
- Lifetime — one-time payment that permanently unlocks current and future membership benefits. You are never charged again.
- Diamond 💎 — one-time payment that includes everything in Lifetime plus Diamond-only benefits such as exclusive themes and exclusive sound recipes. You are never charged again. The exact benefits are listed under "See all Diamond benefits" on the purchase screen.
About future content: while your membership is active (monthly, yearly, Lifetime or Diamond), you can use members-only scenes we add later, not just those available when you bought. Lifetime and Diamond simply mean you pay once and keep this benefit without ongoing payments. We keep adding content but do not promise a specific amount, frequency or theme. Diamond's extra benefits (exclusive themes, sound recipes, etc.) do not take anything away from Lifetime or subscription members.
Automatic renewal
Subscriptions renew automatically before the end of each period at the price you bought at (we will notify you in advance of any price change), unless you cancel at least 24 hours before the current period ends. Auto-renewal is never pre-selected to trick you: choosing a subscription plan is your choice of that renewal type, and we never use pre-checked boxes, bundling or hidden terms.
Before each auto-renewal charge, we aim to remind you at least 5 days in advance through an in-app notice or notification, so you have time to decide. We apply this minimum to all users worldwide.
Free trials
Some subscriptions may include a free trial. If you do not cancel before the trial ends, the regular subscription price is charged automatically. The price and trial length are clearly shown on the purchase screen before you buy.
Starting immediately and your right of withdrawal (EU / UK / EEA)
When you buy a subscription or start a trial, we unlock members-only content immediately. This does not automatically remove your 14-day right of withdrawal. Article 16(m) of the EU Consumer Rights Directive (2011/83/EU) allows that right to be lost for "digital content" once supply begins with your consent, but in its judgment of 9 July 2026 in Case C-234/25 (Sky Österreich Fernsehen), the Court of Justice of the EU distinguished "digital content" (which does not change after supply) from "digital services" (which adapt to how you use them), and only the former can rely on that exception. Night Window's live-mixed sounds, switchable scenes and saved mixes/logs are closer to a digital service, so we take the approach more favourable to you:
If you ask to withdraw (refund) within 14 days of purchase, we will in principle process it even if you have started using the service. Under Article 14(3) of the Directive we may deduct a proportionate amount for the service you actually used and refund the rest — we will not simply refuse, and the deduction will be reasonable, not punitive. If you have not used any members-only content at all, you will receive a full refund.
How to cancel
Subscriptions must be cancelled through the store you bought from; the app cannot cancel for you:
- Google Play: open the Google Play Store app → profile icon → Payments & subscriptions → Subscriptions.
- App Store: Settings → [your name] → Subscriptions.
- Other payment methods (where offered): use the subscription management link in your receipt, or contact us.
Uninstalling the app does not cancel your subscription. Subscriptions are tied to your store account, not to the app on your phone. If you want to stop being charged, cancel first, then uninstall.
After cancelling, you keep your membership until the end of the period you already paid for. We follow the principle that cancelling should be as easy as subscribing: we never hide the cancel option or make you call or email us. Before sending you to your store's subscription settings, we may ask once, in one sentence, whether you'd like to see other plans — but the "Go to subscription settings" button is always just as visible as any other button and takes you there with one tap. (This is a standard we choose to follow voluntarily; the EU's proposed Digital Fairness Act discusses similar rules but was not yet law when these Terms were last updated.)
Refunds
- Google Play purchases: refunds are handled by Google — request one from your Google Play order history.
- App Store purchases: refunds are handled by Apple at reportaproblem.apple.com.
- Other payment methods (where offered): contact us and we will handle your request under applicable consumer protection law.
EU / UK / EEA statutory 14-day withdrawal right: see "Starting immediately and your right of withdrawal" above. If you think a deduction we made is unreasonable, contact us and we will recalculate it as the law requires.
Other regions: any additional mandatory cancellation, withdrawal or other consumer rights under the law where you live are not affected by these Terms.
Before buying Lifetime or Diamond
If you currently have a monthly or yearly subscription and buy Lifetime or Diamond, your existing subscription is not cancelled automatically — they are separate transactions. Please cancel your subscription as described above to avoid further charges. If you are already a Lifetime or Diamond member, you do not need a lower plan; the purchase screen will block such purchases so you don't spend money by mistake.
4. Price changes
We may change prices. If the price of an active subscription goes up, we will notify you in advance as required by the store, and you can cancel before the new price applies. Completed one-time purchases are not affected by later price changes.
5. Intellectual property
The sound synthesis, scene visuals, interface design and text in the app belong to the developer (or are used under license). A membership gives you a license to use this content inside the app; it does not transfer any intellectual property. You may not record, download, redistribute or commercially use the app's sounds or visuals without permission.
6. Prohibited conduct
You may not:
- bypass payment restrictions or membership verification by reverse engineering or modifying the app;
- use the app for anything that breaks the law where you live;
- attack or interfere with the app's normal operation, including its servers and download infrastructure.
7. Disclaimer and limitation of liability
The app is provided "as is". We do not guarantee that it will be uninterrupted, error-free or meet your particular needs. To the maximum extent permitted by law:
- we are not liable for losses caused by network problems, device compatibility, or outages of third-party platforms (Apple, Google or payment providers);
- our total liability (if any) will not exceed the amount you actually paid for the app in the 12 months before the dispute arose;
- nothing in these Terms excludes or limits liability that cannot be excluded or limited by law (for example, for intentional misconduct or gross negligence, or mandatory consumer rights).
Specific service commitments described in the Diamond benefits (such as support response times, price locks or future ad-free guarantees) are goals we commit to within our capacity to keep operating the app. If the app stops operating entirely, these commitments cannot continue; they are not unlimited guarantees outside these Terms.
8. Account termination
If you seriously breach these Terms (for example, by cracking the payment system or attacking our services), we may suspend or terminate your account. You can also request account deletion at any time as described in the Privacy Policy.
9. Changes to these Terms
We may update these Terms from time to time and will post the new version on this page. Significant changes (such as changes to billing) will be announced in advance in the app or through the contact details you gave us. Continuing to use the app means you accept the updated Terms.
10. Users in the United States
There is currently no single federal automatic-renewal law in force in the US (the FTC's 2024 "Click-to-Cancel" rule was vacated by the Eighth Circuit in July 2025, and the FTC restarted its rulemaking in March 2026). Many states have their own automatic renewal laws, with California's generally regarded as the strictest. Wherever you live in the US, we apply California's standard: cancelling is as easy as subscribing, price changes are notified in advance, and renewals are reminded in advance. For subscriptions bought through Google Play or the App Store, billing, cancellation and store-side reminders are operated by Google or Apple under their own policies; we make sure the in-app purchase flow and price display meet our obligations as the developer.
11. Your local consumer rights
Nothing in these Terms excludes or limits the mandatory consumer protection rights that the laws of your country or region of residence give you.
