Plain terms for quiet nights.

Agreeing to these terms #

These are the app-specific terms for Rain Sounds on Android and Apple devices.

These Terms of Use (“Terms”) are between you and Mustafa OZ, trading as Hello World Games & Apps (“we”, “us”, “our”). We publish under the name OZ. They cover Rain Sounds & Sweet Dreams (“Rain Sounds” or “the app”): Android version 3.0 onward, including Android TV, Wear OS and the home-screen widget, and Apple version 1.0 onward for iPhone, iPad, Apple Watch and Apple TV. Features differ by platform and release.

By using the app, you agree to these Terms to the extent permitted by applicable law. Please read them before buying the unlock. If you do not agree, stop using the app. You keep any cancellation, refund or other rights the law gives you. Our Privacy Policy explains data handling; accepting these Terms does not give blanket consent to personal-data processing.

If you lack the legal capacity to enter this agreement where you live, a parent or guardian must authorize your use as required by local law. Purchases are subject to the relevant store’s account-age rules, payment rules and parental controls. A store age rating describes content suitability; it does not override those requirements.

For Apple downloads, the software license is governed by Apple’s Standard EULA as explained in section 03. These Terms add the app-specific product and purchase information below.

The app and your license #

You receive permission to use the app and its content, subject to your store’s usage rules and your legal rights.

Android license

As long as you comply with these Terms, we grant you a personal, non-exclusive license to install and use the Android app on compatible devices that you own or control, for non-commercial use. It is non-transferable except as permitted by applicable law or the store’s rules, and may be ended only as described in section 15. It covers updates we provide unless valid additional terms accompany them. The Google Play Terms of Service also govern your use of that store.

Apple license

For an App Store download, Apple’s Standard Licensed Application End User License Agreement (“Standard EULA”) governs the software license, including its scope, permitted Apple-branded devices, usage restrictions and applicable sharing rights. We, as the app provider, grant that license.

These app-specific Terms supplement the Standard EULA with product information and commitments. They do not replace it or restrict rights granted by its usage rules. We honor the express purchase and support commitments made here, and mandatory consumer law takes precedence over any conflicting disclaimer or limitation.

The Apple Media Services Terms and Conditions also govern store use and purchases. The Privacy Policy describes the data this app actually handles, including the limited store diagnostics we may receive.

The app and sounds are licensed, not sold as copyright ownership. We and our licensors retain rights not granted to you. Store terms control store administration and billing to the extent applicable; neither these Terms nor a store policy removes a mandatory legal remedy.

Free sounds and free listening #

Three sounds are currently free. Each other sound has five minutes of preview listening.

The app includes ten sounds. By the Window, Attic Room and Under the Leaves can currently be played without a time limit or purchase. Each of the other seven sounds has a five-minute preview allowance recorded locally for that installation, usable in one session or over several sessions. Once that allowance is used, access to that sound requires the unlock.

A backup or device restore may preserve used preview time; reinstalling does not guarantee a new allowance. Local preview usage is separate on different devices. We may change the free offering or preview allowance in a future version, with appropriate notice where required. A change will not remove content you have already paid to unlock or reduce mandatory consumer rights.

The one-time unlock #

Pay once in your store to unlock all ten included sounds. No subscription or automatic renewal.

What you receive. “Unlock all sounds” is a one-time in-app purchase, treated as a non-consumable purchase on Apple devices. It removes the limits on the seven locked sounds in the current ten-sound library. You do not need to pay again to restore that entitlement in the same store. It is a license to use the included content, not ownership of the recordings or a promise of perpetual operating-system support.

Price and delivery. The checkout shows the applicable local price and taxes before you confirm. Prices may vary by country or change for later purchases; a later change does not increase a completed purchase. Access is granted when the store confirms a valid completed purchase. A pending payment, parental-approval request or unverified transaction does not yet grant access.

Stores are separate. A Google Play purchase does not unlock the Apple app, and an App Store purchase does not unlock Android. We do not have an app account or service linking those store purchases. Purchasing in one store does not synchronize settings, names, preview use or listening counts across devices.

Family use. Google Play Family Library does not share this in-app purchase. Apple Family Sharing for the unlock applies only if Apple offers it for this particular purchase and the purchase is eligible. Do not assume that joining a family group makes the unlock shareable; the store’s offer and rules determine that.

Checks and offline use. The app checks entitlement through the relevant store and caches access locally. Apple versions also respond to transaction updates, including approvals and revocations. Refunded, reversed or revoked entitlements can lock paid sounds again. The bundled sounds play offline after access is established; buying and restoring require the store and normally a network connection. Offline status does not create an entitlement or guarantee that a purchase can be restored without the store.

Payments, refunds and your right to cancel #

Ask the store that billed you about payment refunds. Contact us for app or entitlement problems.

Payments

Google Play processes Android purchases; Apple processes App Store purchases. Your transaction is subject to that store’s applicable terms and the rights the law gives you. We do not receive your store password, full card number or bank details. The purchase is not a subscription, so there is no recurring plan to cancel.

Google Play refunds

You can use Google Play’s refund process or contact us with your Google Play order reference, usually beginning “GPA.” We can review the request and, where available, process it through Google Play. Eligibility and payment timing depend on the store’s rules and applicable law.

Apple refunds

Request an App Store refund through Apple’s Report a Problem service or Apple Support. Apple administers the payment refund; we cannot directly credit an Apple payment or promise that Apple will approve a request. We can help troubleshoot the app and explain a purchase issue. This does not exclude any remedy you are entitled to claim from us under applicable law.

If a refund or revocation removes the entitlement, paid sounds lock again when the store’s status is applied. Uninstalling or offloading the app does not itself request a refund, reverse a purchase or delete store records.

Withdrawal and cancellation rights

Consumers in the EU, EEA or UK generally have a fourteen-day withdrawal right for distance contracts, subject to applicable exceptions. For immediately supplied digital content, that right can be lost only when the legal conditions are met, including prior express consent to immediate supply, acknowledgment of the resulting loss of the right, and required contract confirmation. Merely reading these Terms or downloading the free app is not that consent. The relevant store’s checkout and local law govern how this applies to your purchase. In Türkiye, the applicable distance-contract exception for immediately supplied electronic services or intangible digital goods may apply, subject to mandatory law and required information.

Faulty or misdescribed digital content

Contact us if the app or unlock does not work as described. We will investigate and provide the correction or other remedy required by applicable law. Depending on the circumstances and your law, remedies can include repair, replacement, a price reduction or a refund. Store refund procedures and withdrawal exceptions do not remove rights for faulty, unavailable or misdescribed digital content.

Health, safety and sensible use #

Rain Sounds is for relaxation and personal comfort. It is not medical care.

• Comfortable volume. Keep sound low and comfortable, particularly for long sessions or headphone use. Use the sleep timer where helpful and stop if sound causes discomfort.
• Children’s surroundings. When using the app near a baby or young child, keep the device outside the crib or bed, away from their ears, at low volume and safely out of reach.
• Awareness. Do not use relaxing audio or interact with the app while driving, operating machinery, or where it could prevent you from noticing alarms or hazards.
• Flashes and animation. Distant Thunder includes lightning effects. Use the app’s Reduce motion control, where shown, or Apple’s system Reduce Motion setting to use a still scene. Stop viewing if an effect causes discomfort.
• Overnight device use. Follow the device maker’s charging, ventilation and audio-output guidance. Keep the device on a firm, uncovered surface, away from bedding.

Mizzle, reminders and the voice #

Mizzle’s prepared messages are friendly app content. Reminders and timers are convenience features.

Mizzle is a fictional rain-cloud character. Its greetings and kind words are written in advance, not a conversation with a person, clinician or AI assistant. The app does not listen to you. Optional names personalize messages locally as described in the Privacy Policy.

Where available, speech depends on the device’s text-to-speech service, installed voices, language and accessibility settings. Speech, motion effects, reminders, widgets, haptics and controls are not identical on phones, watches and TVs. The app does not promise every feature on every supported device.

Bedtime reminders use local operating-system scheduling and can be delayed, silenced or missed because of permissions, Focus or Do Not Disturb, battery limits, a powered-off device or system behavior. Playback and sleep timers can also be interrupted by calls, audio-route changes or the operating system. They are not a reliable alarm, medication reminder, emergency service or safety system.

What you may not do #

Use the app for personal listening and respect the content and purchase rules.

Except to the extent applicable law, an open-source license or the relevant store’s usage rules permits it, you must not:

• copy, extract, redistribute or publish the app’s recordings, artwork, animations, software or Mizzle character, or incorporate them in another product or work;
• broadcast, stream, publicly perform or commercially use the sounds, including in published videos or podcasts or business premises, without our written permission;
• sell, rent, sublicense or transfer the app or unlock outside permitted store or legal arrangements;
• bypass purchase checks, preview limits or security controls, or access paid content without a valid entitlement;
• reverse engineer, decompile, disassemble or modify the app where such restriction is legally enforceable;
• infringe rights, break applicable law or remove copyright and license notices.

Nothing here limits lawful interoperability, accessibility, security research or other rights that cannot be restricted by contract. Apple users must also comply with the Standard EULA’s applicable export and sanctions restrictions and with relevant third-party agreements.

Our content and intellectual property #

The app, its recordings and Mizzle belong to us or the people who license them to us.

The software, sounds, text, scenes, artwork, animations, names and design are protected by intellectual-property laws. Your purchase permits use as described above; it does not transfer copyright or grant permission to use our branding to suggest sponsorship or endorsement.

Open-source components remain governed by their own licenses. Fraunces and Figtree are used under the SIL Open Font License 1.1. Available notices can be read in the app’s Open-source licenses or Licenses screen. These Terms do not reduce rights granted by those licenses.

If you voluntarily send a suggestion about the app, you permit us to use that suggestion to improve it without payment, provided we respect applicable law and your privacy. This permission does not transfer ownership of unrelated works or authorize publication of your private support correspondence.

Stores and other services #

Stores and device services have their own terms. We remain responsible for our app as the law requires.

Google Play or the App Store supplies downloads, checkout, restoration and store controls. Android, Apple operating systems, device makers, speech engines, backup services and audio-output providers supply other parts of the experience. You must comply with applicable third-party agreements. Availability and behavior can change, and a network connection, compatible hardware or provider account may be needed for some services.

Apple’s role

We provide the Apple app and its software license. Under the Apple Media Services Terms and Conditions, we are responsible for our app’s content, maintenance, support, applicable warranties and product-related claims, subject to local law. Apple operates the App Store and has its own store and payment responsibilities; Apple is not responsible for maintaining or supporting our app except as required by applicable law. Those store terms also recognize Apple’s right to enforce the applicable EULA as a third-party beneficiary. App Store payment refunds follow the process in section 06.

For app-specific support, use our email in section 19. For store billing, use the relevant provider’s process in section 06. Nothing in this section shifts responsibility that applicable law places on us.

Updates, changes and availability #

Compatibility and availability depend on the device, release and store listing.

The current minimum versions are Android 8.0 for phones, tablets and TVs; Wear OS 3 or later for watches; iOS/iPadOS 18 or later; watchOS 11 or later; and tvOS 18 or later. Check your store listing before downloading or purchasing: requirements, countries and supported models may differ by release. A listed platform does not guarantee a version is available in your country or on every device.

We may supply updates to fix faults, maintain security, improve the app or comply with legal or platform requirements. You may need an update to keep particular functions or purchases working. We will provide updates required by applicable consumer law. Future minimum operating-system requirements may change.

We may change features or stop offering new downloads or optional support, subject to existing contractual obligations and mandatory law. We do not promise indefinite support or compatibility with future operating systems. An installed copy may continue working offline, but later reinstallation or purchase restoration depends on store availability. If a change or withdrawal materially impairs paid content, we will provide notice and any continued access, termination right, price reduction or refund required by law. This section does not authorize arbitrary removal of an existing paid entitlement.

Disclaimers #

We provide the app with reasonable care, but cannot promise uninterrupted playback or a sleep result.

Subject to express promises, the Standard EULA where applicable, and rights the law does not allow us to exclude, the app is supplied “as is” and “as available”. To the extent permitted by law, we exclude other implied warranties, including merchantability, fitness for a particular purpose and non-infringement. We do not guarantee error-free operation, uninterrupted availability, compatibility with every device or service, or a particular relaxation or sleep outcome.

These qualifications do not remove statutory guarantees, our duty to supply conforming digital content, required security updates, or remedies for a product that is faulty or not as described. Mandatory consumer protections apply wherever you live, including in the EU, EEA, UK, Türkiye, Australia and New Zealand where applicable.

Limitation of liability #

Any limits apply only where the law permits them.

Nothing in these Terms excludes or limits liability for fraud, willful misconduct, gross negligence, death or personal injury caused by our negligence, or any liability or consumer remedy that cannot legally be excluded or limited.

Where lawful, we are not liable for indirect, incidental, special, consequential or punitive losses, or business losses such as lost profits, goodwill or commercial opportunity. For claims governed by these app-specific Terms, our total liability is limited, where that limit is lawful, to the greater of the total amount you paid us for the app and unlock or USD 50 (or its local-currency equivalent).

If you are a consumer, these exclusions and the cap do not apply to the extent they would reduce mandatory remedies or liability for losses the law requires us to cover. For example, where applicable consumer law makes us responsible for reasonably foreseeable loss caused by a breach of contract or a failure to use reasonable care and skill, that protection remains. The Standard EULA’s own provisions govern matters within the Apple software license, subject to the same mandatory-law protections.

Ending these terms #

You may stop using the app at any time. Paid rights are subject to the protections above.

You can stop using the app and remove it from your devices. Uninstalling does not by itself cancel or refund the unlock, and a valid store entitlement can normally be restored with the same store account on a compatible available version.

We may end the Android license or suspend rights under these app-specific Terms for a material or repeated breach, such as intentionally bypassing purchase controls, or where required by law. Where reasonable and legally permitted, we will notify you and allow a reasonable chance to fix a remediable breach. Apple license termination is governed by the Standard EULA. We do not operate a remote app-account suspension service.

Ending these Terms does not remove accrued consumer remedies, lawful refund rights or obligations that by their nature continue, including ownership and dispute provisions.

Governing law and disputes #

Turkish law governs these app-specific Terms, subject to mandatory protections where you live.

Please contact us if a problem arises so we can try to resolve it. You are not required to complete an informal process before exercising a statutory right or seeking an urgent remedy.

These app-specific Terms are governed by the law of the Republic of Türkiye. Subject to mandatory jurisdiction rules, the courts and enforcement offices of Çanakkale have jurisdiction over disputes under these Terms. Apple’s Standard EULA has its own governing-law provisions for matters it governs.

• If you are a consumer, you retain the mandatory protections of your country of habitual residence and access to any court or dispute-resolution body available under applicable law. This choice of law does not take those rights away.
• Consumers in Türkiye may apply to the competent Consumer Arbitration Committees (Tüketici Hakem Heyetleri) or Consumer Courts, including those available where they live, subject to the applicable rules and monetary limits.

These Terms do not impose binding arbitration or waive a collective-action right available under mandatory law.

Changes to these terms #

Material changes need appropriate notice and cannot rewrite completed purchases retroactively.

We may revise these Terms for app changes, legal requirements or reasonable operational needs. We publish revisions here with an updated date and provide appropriate advance notice of material changes through the app or relevant store listing. Where the law requires express agreement, we obtain it; continued use alone does not replace that requirement.

Changes apply prospectively. They do not remove a completed purchase, an accrued claim or a mandatory right. If you disagree with a change, you may stop using the app and use any termination or refund remedy provided by applicable law. Apple administers changes to its Standard EULA and store terms separately.

General #

These terms work alongside the store license and the rights you cannot waive.

• Agreement. These Terms describe the app-specific agreement with us. The Privacy Policy describes information handling; relevant store terms and the Standard EULA apply as explained in section 03. Specific purchase descriptions and binding consumer promises are not excluded.
• Invalid provisions. If a provision is unenforceable, the rest continues to apply to the extent the law allows. A provision is not replaced in a way that reduces mandatory consumer rights.
• No waiver. A delay in enforcing a right does not by itself give up that right.
• Transfer. We may transfer our rights and duties with the app or business only as permitted by law and without reducing your rights. We will give notice where required. Your ability to transfer or share a license follows applicable law and the store rules.
• Language. English is the source text for these Terms. Any local-language interpretation, disclosure or consumer protection required by law prevails over a conflicting language-priority provision.
