Welcome to InstaSign (hereinafter referred to as the "App"). Before using the App, please read and fully understand all the contents of these Terms of Service. If you do not agree with any part of these Terms, please stop using the App immediately. If you continue to use the App, you will be deemed to have read, understood, and agreed to accept all the contents of these Terms.

Important Notice: The App is an offline application, and we do not have a backend server. All data (including but not limited to personnel information, face feature data, attendance records, etc.) is processed and stored locally on your device, and will not be uploaded to any server. The App only uses network permissions in very limited scenarios (such as downloading images from network links for import purposes), as detailed in the Privacy Policy.

The App does not require you to register or log in to any account, nor will it create an online account for you. What you maintain in the App is only a local personnel list for attendance management.

5. Disclaimer

• 1. Face Recognition Accuracy: The face recognition functionality of the App is implemented based on existing technology and may be affected by various factors such as lighting, angle, occlusion, device performance, etc., and cannot guarantee 100% recognition accuracy. We are not responsible for any consequences caused by recognition errors or recognition failures.
• 2. Device Compatibility: Although we strive to ensure that the App functions properly on compatible devices, we do not guarantee that the App will work perfectly on all devices, nor are we responsible for any issues caused by device incompatibility.
• 3. Data Loss Risk: Since the App is an offline application and data is stored locally on your device, there is a risk of data loss due to device failure, loss, damage, system updates, app uninstallation, etc. We are not responsible for any data loss. We recommend that you regularly back up your data.

• 2. Liability Cap: Even if we are required to bear liability for violating these Terms, our total liability shall not exceed the fees you actually paid for using the App (if any).
• 3. Force Majeure: We are not responsible for the App's inability to function normally or data loss caused by force majeure (such as natural disasters, war, strikes, government actions, etc.). Since the App is an offline application and has no backend server, network failures will not affect the core functionality of the App.
