Effective date: April 1, 2026 · Last updated: August 3, 2026
These Terms of Service ("Terms") are an agreement between you and Filip Kowalski, trading as Slo ("we," "us," or "our"), and govern your use of the Slo application for iOS, Android and Mac (the "App"), distributed through the Apple App Store (including the Mac App Store) and Google Play. By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree, do not use the App.
These Terms are between you and us alone. Apple and Google are not parties to them and are not responsible for the App or its content.
The App provides ambient sounds for general relaxation and entertainment purposes only. The App is not a medical device and is not intended to diagnose, treat, cure, or prevent any medical condition, including but not limited to insomnia, tinnitus, anxiety, or other health conditions.
You acknowledge that the sounds and features provided are not a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of a qualified healthcare provider with any questions regarding a medical condition. If you have a sleep disorder or any medical condition that may be affected by ambient sounds, consult your healthcare provider before using this App.
You must be at least 13 years of age (or 16 in the EEA) to use the App. If you are under the age of majority in your jurisdiction, you may only use the App with the consent of a parent or legal guardian.
We grant you a limited, non-exclusive, non-transferable, revocable license to use the App for personal, non-commercial purposes in accordance with these Terms.
You agree not to:
The App is free to download and use. The free tier is supported by advertising served through Google AdMob, and some content is available only to subscribers or by watching a rewarded ad. Ads are not shown during the first three days after installation. A paid subscription removes advertising.
How your data is handled in connection with advertising, including consent and your choices, is described in our Privacy Policy.
The App offers optional premium features through subscription plans and one-time in-app purchases, sold and billed by Apple through the App Store or by Google through Google Play. We are not the merchant of record.
All content in the App, including but not limited to sounds, music, graphics, text, icons, logos, and software, is the property of Slo or its licensors and is protected by copyright, trademark, and other intellectual property laws.
The ambient sounds are licensed for personal listening through the App and through the player on slonoise.com. You may not extract, download, record, or redistribute the audio content for any purpose.
Some sounds are third-party recordings used under their own licences, including Creative Commons licences from Freesound. Those recordings remain the property of their creators, who are credited in the App and on our sound credits page, and their own licence terms govern any use outside the App and the website.
The App integrates with third-party services including Google AdMob (advertising and advertising consent), Google Analytics for Firebase (analytics), Firebase Crashlytics (crash reporting), RevenueCat (subscription management and install attribution), and Apple's Ad Services and the Google Play install referrer (advertising attribution). Sound files are streamed from our audio host. Your use of these services is subject to their respective terms and privacy policies, and what each one receives is set out in our Privacy Policy.
The App has no user accounts. What we collect, who receives it, and how to ask us to delete it is described in our Privacy Policy, which forms part of these Terms.
The App is provided on an "AS IS" and "AS AVAILABLE" basis without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement.
We do not warrant that the App will be uninterrupted, error-free, or free of harmful components. We make no guarantees regarding the effectiveness of the sounds for sleep, relaxation, focus, or any other purpose. Audio playback depends on your device's operating system and battery settings, and some devices stop background playback in ways we cannot control.
Nothing in these Terms excludes or limits any statutory rights you have as a consumer that cannot be excluded or limited under the law of your country of residence.
To the maximum extent permitted by applicable law, Slo and its affiliates, officers, employees, and agents shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, or goodwill, arising out of or in connection with your use of the App.
Our total aggregate liability for any claims arising from your use of the App shall not exceed the amount you paid for the App and its in-app purchases in the 12 months preceding the claim.
You agree to indemnify and hold harmless Slo and its affiliates from any claims, damages, losses, or expenses (including reasonable attorney's fees) arising from your use of the App or violation of these Terms.
We may suspend or terminate your access to the App at any time, with or without cause, and with or without notice. Upon termination, your license to use the App will immediately cease. Terminating your access is not the same as deleting your data; to have your data deleted, follow the process in our Privacy Policy.
The following applies where you obtained the App from the Apple App Store, and is required by Apple.
These Terms are governed by the laws of Spain, without regard to conflict of law principles. The courts of Spain have jurisdiction over any dispute arising from these Terms. If you are a consumer resident in the European Union, the United Kingdom, or another jurisdiction whose law grants you the right to bring proceedings in your own country's courts, that right is unaffected.
We may update these Terms from time to time. We will notify you of material changes by posting the updated Terms in the App or on this page with a revised "Last updated" date. Your continued use of the App after changes constitutes acceptance of the updated Terms.
If any provision of these Terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.
