By downloading or using Round Rush (the “App”), you agree to these Terms of Service (“Terms”). If you do not agree to these Terms, please do not use the App.
Round Rush is an interval timer app designed to help users manage workout sessions using rounds, workout time, and rest time in a clean, minimal interface. The App may include features such as:
Round-based interval timer setup (rounds / workout time / rest time)
Session running screen with clear progress and remaining time
Sound cues and/or vibration for phase changes and session completion
Presets, favorites, and recent configurations (if available)
Local history of sessions (stored on-device, if enabled)
Optional background operation with notifications when a session ends (if available)
Optional export/share features (for example, saving or sharing session results via system share features, if available)
The App is provided “as is” for personal and non-commercial use.
Round Rush is designed to work without requiring account sign-in. Depending on your device and enabled features, the App may request access to certain device permissions, such as:
Internet access (to fetch remote content such as ads, analytics, or optional resources)
Notifications (to alert you when a timer phase or session ends, if supported and enabled)
Alarm/background related capabilities (to keep timers reliable depending on OS rules, if applicable)
Photos/Media/Storage access (only if the App provides save/export/share features that require file access)
If you deny required permissions, some features may not function properly or may be unavailable.
You agree to use the App only for lawful purposes and in accordance with these Terms. You must not:
Reverse engineer, decompile, or modify any part of the App
Use the App to distribute malware, spam, or harmful content
Attempt to gain unauthorized access to the App’s data or systems
You are solely responsible for how you use the App and any content you choose to save or share from the App.
Round Rush provides timing guidance for convenience only and does not provide medical, health, or professional training advice. Timer behavior may vary depending on device performance, battery optimization settings, OS restrictions, notification settings, and background limitations.
You are responsible for using the App safely, including verifying timing when necessary and stopping exercise if you feel unwell. Flowbit Labs is not responsible for decisions or outcomes based on the information shown in the App.
The free version of the App may display advertisements through Google AdMob or similar third-party networks. We may also offer:
In-app purchases to remove ads or unlock premium features (if applicable)
Rewarded ads that may temporarily unlock benefits (if applicable)
All purchases are handled through the official Google Play Store billing system, and refunds are processed according to Google’s policies. We do not provide direct refunds outside of what is supported by Google Play.
The App is provided “as is” without warranties of any kind, express or implied. We do not guarantee that the App will always function without interruption, error, or defect, or that any issues will be corrected immediately. Use of the App is at your own risk.
To the fullest extent permitted by law, Flowbit Labs is not liable for any direct, indirect, incidental, or consequential damages resulting from:
Your use or inability to use the App
Any loss of local history, presets, cached data, or settings due to device issues, OS updates, storage limitations, permission changes, battery optimization, or app crashes
Any timer interruptions, missed notifications, delays, or inaccuracies caused by system restrictions or background limitations
Any actions or failures of third-party services such as advertising networks, analytics providers, sharing components, or billing services
Some jurisdictions do not allow certain limitations of liability, so some of the above limitations may not apply to you.
We may suspend or terminate your access to the App at any time, without prior notice, if you violate these Terms or misuse the service. You may also stop using and uninstall the App at any time.
We may update or modify these Terms from time to time. The updated version will take effect once it is posted with a new “Last updated” date. Continued use of the App after such updates means you accept the revised Terms.
We may also update the App itself (for example, new features, bug fixes, timer reliability improvements, sound updates, or UI changes).
These Terms are governed by and construed in accordance with the laws of the Republic of Korea, without regard to its conflict of law principles.
