stiff.

Terms of Service

Last updated: April 12, 2026
Effective date: April 12, 2026

These Terms of Service ("Terms") govern your access to and use of stiff. ("the App"), operated by Magnolia Labs Limited ("we," "us," or "our"), a company registered in Hong Kong SAR. 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 form a legally binding agreement between you and Magnolia Labs Limited. Please read them carefully.

1. Eligibility

You must be at least 12 years of age to use the App. The App is rated 12+ on the Apple App Store. By using the App, you represent and warrant that you:

• Are at least 12 years old
• If you are between 12 and 17 years of age, you have the permission of a parent or legal guardian to use the App
• Have (or your parent or legal guardian has on your behalf) the legal capacity to enter into a binding contract in your jurisdiction
• Are not prohibited from using the App under applicable laws
• Will use the App only for lawful purposes in accordance with these Terms

If you are accessing the App on behalf of a minor, you represent that you are that person's parent or legal guardian and accept these Terms on their behalf. You acknowledge and agree that the App's brand voice includes passive-aggressive humor and guilt-based motivation that may not be appropriate for all users, and you have evaluated whether the App is suitable for the minor in your care.

2. What stiff. Does

stiff. is a screen time management and stretch wellness app for iOS. It monitors your screen usage, blocks selected apps after a configurable threshold, and requires you to complete a camera-verified or motion-verified stretch routine to unlock those apps. The App includes collectible shrimp characters earned through an experience point ("SP") system based on stretch activity.

All features are available during a 7-day free trial. After the trial, a paid subscription is required to continue using the App's core features including app blocking.

3. Brand Voice and Humor Disclaimer

stiff. is designed with an intentionally irreverent, passive-aggressive brand voice. The shrimp mascot's commentary, including notifications, mood text, weekly reviews, and in-app messages, is intended as humor and is not:

• Medical, psychological, or professional advice of any kind
• A genuine assessment of your physical health, mental state, or character
• An attempt to shame, humiliate, or cause distress
• A substitute for real human connection or professional support

If any humor feature causes you genuine distress, you can disable notifications, change the mascot's name to something you find less personal, or uninstall the App at any time. The App is designed to be dismissable and never attempts to prevent you from closing it or uninstalling it.

The App is not appropriate for individuals who may be sensitive to critical language, self-deprecating humor, or guilt-based motivation strategies. Please evaluate whether the brand voice is appropriate for you before the trial period ends.

4. Health and Safety Disclaimer

stiff. provides general stretch guidance for wellness purposes only. The App is not a medical device and does not provide medical advice, diagnosis, or treatment.

• Consult a qualified healthcare provider before starting any stretch routine, especially if you have injuries, chronic pain, pregnancy, recent surgery, cardiovascular conditions, or other medical conditions
• Stop stretching immediately if you experience pain, dizziness, shortness of breath, numbness, or any discomfort
• stiff. is not a substitute for professional physiotherapy, medical treatment, mental health services, or clinical advice
• We make no claims about the medical effectiveness, therapeutic benefits, or health outcomes of the stretch routines provided
• The stretches provided are general wellness activities, not prescribed exercises
• Individual results will vary and are not guaranteed
• The stretch instructions provided in the App are general guidance only and may not be appropriate for your specific body, fitness level, or medical conditions. Always modify or skip stretches that feel uncomfortable or unsafe for you. The App cannot evaluate your individual physical capabilities or detect contraindications based on your medical history

By using the App, you acknowledge that you engage in stretch activities at your own risk and release Magnolia Labs Limited from any liability related to physical injury arising from performing stretches suggested by the App.

5. App Blocking and Screen Time

stiff. uses Apple's Screen Time and Family Controls APIs to block apps you select.

• You choose which apps to block. We strongly recommend you do not block apps required for emergencies, work, communication, safety, banking, navigation, or medical purposes
• You can pause the App at any time from settings (1, 6, or 24 hours) or use the emergency unblock button on the shield itself
• You can disable stiff. entirely by revoking Screen Time permissions in your device settings
• Uninstalling the App immediately removes all shields and blocking
• In the event of trial expiry without a paid subscription, all shields are automatically removed and blocking is disabled

You acknowledge and agree that:

• stiff. is not responsible for any consequences arising from apps being blocked, including but not limited to missed calls, missed messages, missed emergencies, work disruptions, financial losses, missed appointments, delayed medical care, or any inability to access specific apps when needed
• You are solely responsible for deciding which apps to block
• You should not rely on stiff. as a safety-critical service
• The App may fail to block apps due to iOS limitations, permission changes, subscription expiry, or technical issues
• The App may fail to unblock apps in edge cases, and you should always know how to uninstall the App as a last-resort unblock method

IF YOU NEED GUARANTEED ACCESS TO ANY APP AT ANY TIME, DO NOT BLOCK IT WITH STIFF.

6. Camera and Motion Sensors

• Camera access is used solely to verify you are stretching during a session. No images or video are recorded, saved, or transmitted. Camera frames are processed in volatile memory (RAM) and discarded immediately after evaluation
• The App does not perform facial recognition and does not collect, store, or process biometric data
• Motion sensor access is used in stealth mode to verify movement without the camera. No sensor data is saved or transmitted
• Pose estimation coordinates are used transiently for real-time stretch verification and are not retained
• You can choose between camera and stealth verification modes. Both permissions are optional and can be revoked at any time in your device's Settings
• See our Privacy Policy for full details

Free Trial Eligibility

• Apple's account-level policies determine trial eligibility
• Abuse of the trial system (creating multiple accounts, using refunded purchases to re-qualify, etc.) may result in termination of access

8. In-App Gamification and Virtual Items

stiff. includes a collectible shrimp system with the following important characteristics:

• Shrimp points ("SP") are earned only through completing stretches. SP cannot be purchased with real money, cannot be transferred, cannot be redeemed for cash, and have no monetary value
• Shrimp cards are obtained through an SP-based draw system. Draws use weighted random mechanics. Specific drop odds are determined by the App and may be adjusted in future updates
• Shrimp cards and SP are virtual items for entertainment purposes only. They have no real-world value, cannot be traded, sold, or exchanged, and may be reset, modified, or removed at any time by Magnolia Labs Limited
• Progress in the shrimp collection system does not confer any real rights, benefits, or value outside the App
• If the App is discontinued, or if your subscription ends, access to the gamification system may be terminated and virtual items may become permanently inaccessible

The gamification system is a game mechanic, not a purchasable good. By using the App, you acknowledge that virtual items are not property and do not grant any ownership rights.
