These Terms of Use ("Terms") govern your use of the Granular Volume mobile application ("the app"), developed and published by an independent developer (Rotem Zussman, "the developer"). By installing or using the app, you agree to these Terms. If you do not agree, do not install or use the app.
The app is a software utility that adds fine-grained, software-level volume steps below your Android device's built-in minimum volume, controlled through a small floating on-screen control. It processes your device's audio output locally, on the device. It is a convenience utility only.
The app is a convenience utility only. It is not a medical device, is not hearing protection equipment, and is not a substitute for professional medical advice, diagnosis, or treatment of any hearing or other condition. Actual loudness depends on your device's operating system, your audio hardware, your headphones or speakers, and the content you play. You remain solely responsible for choosing listening levels that are safe for you.
BY USING THE APP, YOU ACKNOWLEDGE AND ACCEPT THE RISKS INHERENT IN AUDIO PLAYBACK ON A MOBILE DEVICE, INCLUDING THE POSSIBILITY OF UNEXPECTED OR INCORRECT VOLUME BEHAVIOR CAUSED BY OPERATING SYSTEM CHANGES, DEVICE HARDWARE, OR SOFTWARE DEFECTS. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE DEVELOPER IS NOT LIABLE FOR HEARING-RELATED DISCOMFORT, INJURY, OR OTHER HARM ARISING FROM YOUR USE OF THE APP OR FROM UNEXPECTED AUDIO OUTPUT. THIS SECTION DOES NOT LIMIT ANY LIABILITY THAT CANNOT BE LIMITED OR EXCLUDED UNDER THE LAW OF YOUR COUNTRY OF RESIDENCE, INCLUDING LIABILITY FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE WHERE SUCH A LIMITATION IS NOT PERMITTED.
The app's source code is free software, licensed under the GNU General Public License version 3.0 (GPL-3.0), available at github.com/Rzuss/granular-volume. Nothing in these Terms limits, replaces, or overrides any right you have under the GPL-3.0 with respect to the source code. These Terms govern your use of the compiled application as distributed through Google Play or F-Droid, to the extent they do not conflict with that license.
The app's name, logo, and store presence identify the developer's own builds. The GPL-3.0 license to the source code does not grant a license to use the app's name or branding on derivative works in a way that suggests they are the developer's official releases.
You agree not to use the app in any unlawful way, and not to misrepresent modified or redistributed builds of the app as official releases of the developer.
THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW. THE DEVELOPER DOES NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR COMPATIBLE WITH EVERY DEVICE, ANDROID VERSION, OR AUDIO CONFIGURATION.
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE DEVELOPER SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES ARISING OUT OF OR RELATING TO YOUR USE OF, OR INABILITY TO USE, THE APP. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE DEVELOPER'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE APP OR THESE TERMS SHALL NOT EXCEED A SUM OF 50 USD. Nothing in this section excludes or limits any liability that cannot be excluded or limited under applicable law, and nothing in these Terms limits your statutory rights as a consumer.
The developer has no obligation to provide ongoing technical support, maintenance, bug fixes, or future updates for the app. The developer may update, change, or discontinue the app or any feature at any time. If these Terms change, the updated version will be posted at this address with a revised "Last updated" date. Material changes will be reflected here before or at the same time as they take effect. If the app ever adds an optional purchase, these Terms will be updated first to describe it.
You agree to indemnify, defend, and hold harmless the developer from and against any and all claims, liabilities, damages, losses, costs, and expenses (including reasonable legal fees) arising out of or in any way connected with your use of the app, your violation of these Terms, or your violation of any third-party rights.
If any provision of these Terms is found to be unenforceable or invalid under any applicable law, that unenforceability or invalidity will not render the rest of these Terms unenforceable or invalid. The affected provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will continue in full force and effect. This applies in particular to Section 2, where consumer-protection law in some countries does not permit a limitation of liability for personal injury caused by negligence: if that specific limitation is found unenforceable where you live, it is removed to that extent only, and the rest of these Terms, including the rest of Section 2, remains in effect.
These Terms, together with the Privacy Policy, constitute the entire agreement between you and the developer relating to your use of the app, and supersede all prior or contemporaneous communications and proposals about the app, whether oral or written, including anything stated in marketing materials, community posts, or direct correspondence.
These Terms, and any dispute arising from or relating to them or to your use of the app, are governed by the laws of the State of Israel, without regard to its conflict-of-laws principles, and subject to the exclusive jurisdiction of the competent courts of Tel Aviv-Jaffa, Israel, except where the mandatory consumer-protection law of your country of residence grants you the right to bring proceedings, or to rely on local law, in your own jurisdiction. Before filing a claim, you agree to first contact the developer at the email below and allow a reasonable opportunity to resolve the issue informally.
