Thank you for using "Super Calculator" (hereinafter referred to as "this App"). We deeply understand the importance of user privacy and adopt strict technical measures to protect your personal information. This Privacy Policy is intended to clearly and transparently explain how we handle your data. Please read it carefully before using this App.
1. Data Storage and Processing Principles
This App is a completely offline calculation tool that adheres to the following core principles:
1. Local Calculation and Storage: All numbers, expressions, and calculation results you input are stored only on your local device, and in the iCloud account associated with your Apple ID (if you enable iCloud sync). We never upload any of this data to any server operated or controlled by us.
2. No Backend Servers: This App has no backend servers. This means we cannot collect, store, process, or access any of your calculation data, history, or preferences. All calculations are performed locally on your device.
3. Data Ownership: You fully own and control all your calculation data and history. You can delete or manage your data through this App's features or directly through Apple's iCloud settings.
Core Commitment: We never collect, upload, or analyze any numbers or calculation expressions you input. Your calculation process remains entirely yours.
2. Information We Collect
For the basic operation and functionality of this App, we only access information in the following necessary circumstances, in compliance with Apple's (iOS/iPadOS) standard practices:
1. iCloud Read/Write Permission (Optional): When you enable iCloud sync, this App requests system access to the storage space allocated for this App within your iCloud Drive, allowing cross-device synchronization of your calculation preferences, history, or saved constants. This process is fully managed by Apple's system. We cannot access other data in your iCloud, nor can we read the specific numerical content you sync.
2. Anonymous Diagnostic Data (Optional): Based on your system settings, Apple may provide us with completely anonymous, personally unidentifiable aggregated data through its "App Analytics" feature, such as app crash reports, performance metrics, and feature usage frequency (e.g., statistics like "number of times scientific calculator mode was opened," which never includes any input numbers or calculation results). You can choose whether to share such data with app developers by going to "Settings" > "Privacy & Security" > "Analytics & Improvements" on your iOS/iPadOS device.
What We Never Collect: We never collect your identity information (such as name, email, Apple ID), device unique identifiers, location information, nor do we ever collect the specific content of any numbers, formulas, or calculation history you input.
3. Data Security
1. Local Security: Your calculation data stored locally on your device is protected by system-level security measures such as device passcode and biometric lock. Since data never leaves your device, the risk of interception during network transmission is fundamentally avoided.
2. iCloud Sync Security (if enabled): If you choose to enable iCloud sync, encrypted transmission of your data during cross-device synchronization is fully managed and handled by Apple Inc., adhering to its globally leading security standards.
3. Our Measures: Since we do not operate any servers or transmit your data to our systems, the risk of data interception, leakage, or unauthorized analysis on our end is fundamentally eliminated.
4. Third-Party Services
The optional sync feature of this App relies on Apple iCloud Service. Your use, storage, and security of iCloud data are also subject to Apple's iCloud Terms and Conditions and its Privacy Policy. We recommend reviewing Apple's policies to understand their data handling practices.
Apart from Apple iCloud, this App does not integrate any other third-party analytics, advertising, social, or data collection SDKs. We have no advertising networks or data broker partners.
5. Your Rights
You always have full control over your own data:
• Access and Modification: You can directly access and modify all calculation records and saved values within this App.
• Delete Data: You can clear individual or all calculation history within the App. To permanently delete synced data stored in iCloud, you can go to "Settings" > "[Your Name]" > "iCloud" > "Manage Account Storage" > "Super Calculator" on your iOS/iPadOS device.
• Stop Sync: You can turn off iCloud sync for this App at any time within the App's settings or the system's iCloud settings. Once disabled, new data will only be saved on the current device.
• Decline Anonymous Diagnostics: You can always turn off the "Share with App Developers" option in "Settings" > "Privacy & Security" > "Analytics & Improvements". This will not affect any core calculation features of this App.
6. Children's Privacy
This App does not knowingly collect any personal information from users of any age. Since we do not collect names, contact information, or any identifiable information, and all calculation data remains on the user's local device, we cannot and do not need to distinguish users by age. We encourage parents and guardians to guide children in using calculation tools safely and responsibly.
7. Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes in law, technology, or our operational practices. The updated policy will be posted on this page with an updated "Last Updated" date. For material changes (such as fundamental changes to data processing methods), we will notify you through a prominent notice within the App. We recommend that you review this policy periodically.
