Effective Date: September 30, 2025
By downloading, installing, or using the XCalc application (the "Service"), you agree to be bound by these Terms of Service. If you disagree with any part of the terms, you must not use the Service. These terms apply to all visitors, users, and others who wish to access or use the Service.
Local Storage: XCalc stores all user-generated data (files, photos, videos, recordings, passwords) **exclusively on your local device**. We do not host, back up, or have access to any content or data created within the app.
Password and Security: Any passwords or security credentials you set are **encrypted locally** on your device. XCalc developers cannot recover your password. **You are solely responsible for protecting your password** and maintaining the security of the data stored on your device. We are not liable for any loss of data due to forgotten passwords, device failure, or device loss.
Permissions: The App uses **Camera, Microphone, Photo Library, and Biometrics (Face ID/Touch ID)** only to enable user-requested features (e.g., taking a photo, recording audio). This access is controlled by the operating system, and the captured data remains on your device.
XCalc is provided to you free of charge and is supported by advertising. We integrate third-party services for advertising and analytics:
These third-party providers may collect device-level identifiers for personalized advertising purposes, subject to your explicit consent via the **App Tracking Transparency (ATT) framework**. You agree to the display of advertisements within the Service.
We reserve the right to modify or replace these Terms at any time. We will provide at least 30 days' notice before any new terms take effect. By continuing to access or use our Service after those revisions become effective, you agree to be bound by the revised terms.
