These Terms of Use (“Terms”) govern your use of Sloth, a mobile alarm
application for climbers (“the App”, package name com.sloth.app), operated
by Luca Gudermann (“we”, “us”, “our”). By downloading, installing, or using the App,
you agree to these Terms. If you do not agree, do not use the App.
1. About Sloth
Sloth is an alarm clock that requires you to complete a physical camera-verified challenge before the alarm can be silenced. Challenges may include hangboard holds, push-ups, pull-ups, or sit-ups. The App uses on-device pose detection to verify that you are performing the selected exercise.
Sloth is a wake-up tool, not a medical, coaching, or training programme. Climbing and bodyweight exercises carry risk of injury. You are solely responsible for exercising safely, warming up appropriately, using properly installed equipment, and stopping if you feel pain or discomfort.
2. Eligibility
You must be at least 16 years old to use the App, or the minimum age required in your country if higher. If you are under 18, you confirm you have permission from a parent or guardian.
3. Your responsibilities
When using Sloth, you agree to:
- Use the App only for lawful personal purposes
- Provide accurate information when creating an account or subscription
- Ensure your hangboard, pull-up bar, phone mount, and training area are safe and secure before each use
- Inspect holds, anchors, and mounting hardware before relying on them during a wake-up challenge
- Not use the App while operating vehicles, machinery, or in any situation where distraction could cause harm
- Not attempt to bypass, disable, or cheat the alarm or camera verification systems
- Grant only the device permissions needed for the features you choose to use
4. Camera verification and AI limitations
Sloth uses automated, on-device analysis to detect exercise postures. This technology is imperfect. Verification is based on body pose heuristics, not professional coaching judgment or medical measurement. The App may:
- Fail to detect a valid exercise in poor lighting or with a partially obscured body
- Accept a posture that does not meet your personal training standards
- Behave differently across devices, camera angles, and room setups
You acknowledge that camera verification is a convenience feature to help you wake up, not a guarantee of correct exercise form or training quality.
5. Alarms and device reliability
We design Sloth to fire alarms reliably using native platform scheduling (including exact alarms on Android and system alarms on supported iOS versions). However, alarm delivery can still be affected by factors outside our control, including:
- Denied or revoked permissions (notifications, exact alarms, battery optimisation)
- Operating system restrictions, Do Not Disturb, Focus modes, or silent mode behaviour
- Device reboot, low battery, or manufacturer-specific power management
- App updates, crashes, or network issues during first-time model download
Do not rely on Sloth as your only alarm for critical appointments (medical procedures, flights, employment, exams, etc.). Use a backup alarm.
6. Accounts
Sign-in is optional. If you create an account via Google, Apple, or email through Firebase Authentication, you are responsible for maintaining access to that account and for activity under it.
7. Subscriptions and payments
Some features require a paid subscription (“Sloth Pro” or similar). Subscriptions are sold through the Apple App Store or Google Play and managed via RevenueCat. Payment terms, billing cycles, renewals, cancellations, and refunds are governed by the applicable app store’s policies.
- Subscriptions renew automatically unless cancelled before the renewal date
- Manage or cancel subscriptions in your Apple ID or Google Play account settings
- We do not control app store refund decisions
- Free trials or promotional pricing, if offered, will be described in the App or store listing
8. Free and premium features
We may change which features are free or premium over time. If you have an active paid subscription, you will retain access to the premium features included in your plan for the paid period, subject to these Terms and store policies.
9. Intellectual property
The App, including its design, code, branding, and content, is owned by Luca Gudermann or our licensors. We grant you a limited, non-exclusive, non-transferable, revocable licence to use the App for personal, non-commercial purposes in accordance with these Terms. You may not copy, modify, reverse engineer, resell, or redistribute the App.
10. Prohibited conduct
You may not:
- Use the App to harm yourself or others
- Interfere with or disrupt the App’s operation
- Attempt to access data or systems without authorisation
- Use automated tools to scrape or abuse the service
- Misrepresent your identity or affiliation
11. Disclaimer of warranties
The App is provided “as is” and “as available” without warranties of any kind, whether express or implied, including fitness for a particular purpose, uninterrupted operation, or error-free performance. We do not warrant that alarms will always fire on time, that AI verification will always be accurate, or that the App will meet your training goals.
12. Limitation of liability
To the maximum extent permitted by applicable law, Luca Gudermann shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including lost profits, missed appointments, injury, or property damage arising from your use of the App or reliance on its alarms or exercise verification.
Where liability cannot be excluded, our total liability for any claim relating to the App is limited to the amount you paid us for the App in the twelve (12) months before the event giving rise to the claim, or EUR 50, whichever is greater.
Nothing in these Terms limits liability for death or personal injury caused by negligence where such limitation is not permitted by law, or for fraud or intentional misconduct.
13. Indemnity
You agree to indemnify and hold us harmless from claims, damages, and expenses (including reasonable legal fees) arising from your misuse of the App, violation of these Terms, or injury resulting from your training activities while using the App.
14. Termination
You may stop using the App at any time by uninstalling it and cancelling any active subscription through your app store account. We may suspend or terminate access if you violate these Terms or if required for legal or security reasons.
15. Changes to the App and Terms
We may update the App or these Terms from time to time. Material changes will be posted at this URL with an updated date. Continued use after changes take effect constitutes acceptance of the revised Terms.
16. Governing law and disputes
These Terms are governed by the laws of Germany, excluding conflict-of-law rules. If you are a consumer resident in the EU, you also benefit from mandatory protections of your country of residence. The courts of Berlin, Germany shall have jurisdiction where permitted by law.
