AXIOM & Privacy

AXIOM AI is designed to protect your information and enable you to choose what you share.

What is Personal Data at AXIOM AI?

At AXIOM AI, we believe strongly in fundamental privacy rights — and that those fundamental rights should not differ depending on where you live in the world. That’s why we treat any data that relates to an identified or identifiable individual or that is linked or linkable to them by AXIOM AI as “personal data,” no matter where the individual lives. This means that data that directly identifies you — such as your Apple ID — is personal data, and data that does not directly identify you, but that can reasonably be used to identify you — such as your learning records and practice data — is also personal data.

Personal Data Collected by AXIOM AI

We believe that AXIOM AI can provide excellent learning experiences while effectively protecting your privacy. Given our Serverless Architecture, we limit the data we collect to the absolute minimum.

Account Identity

When you use "Sign in with Apple", we only receive your unique Apple ID identifier. This is a technical credential required for CloudKit private database synchronization. We do not request, access, or store your email address.

Profile Information (Optional)

We ask for a nickname to greet you on the app’s "Account Settings" page. This is entirely optional. If you choose to hide or not provide a nickname, the App will address you as "You" by default. This information is stored only locally on your device and in your private iCloud database; it is never uploaded to developer or third-party servers.

Zero-Tracking Commitment & Apple Diagnostics

We do not integrate any third-party behavioral tracking SDKs (such as Firebase, Umeng, or Facebook SDK). Your clickstream, browsing habits, and usage time data belong entirely to you. Regarding App crash data and performance metrics, we rely entirely on Apple's anonymous diagnostic services. Only if you opt in to "Share Analytics with Developers" in iOS system settings may we receive anonymous crash reports via Apple for bug fixing.

Learning Data

Your word library records, practice statistics, and multidimensional interaction data. These are the core elements powering our "Adaptive Intelligence Engine." This data is stored 100% in your iCloud private database. Per Apple's privacy design, even the developer cannot view the content stored in the CloudKit private database.

AXIOM AI’s Use of Personal Data

We process your personal data based on the following legal bases in compliance with the General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), Personal Information Protection Law (PIPL), and applicable laws in your region:

• Contract Performance: Processing your learning progress to provide the service functions you requested.
• Consent: Accessing the microphone for pronunciation assessment based on your explicit authorization.
• Legitimate Interests: Necessary analysis for cybersecurity, fraud prevention, and improving App experience.

Providing Our Services

AXIOM AI collects necessary personal data to power our services, which may be used for product or service improvement, for internal purposes such as auditing or data analysis, or for troubleshooting. For example, when you practice words, we record your learning progress to provide personalized review schedules and study recommendations. All such processing is done locally on your device or within your private iCloud database via Apple's CloudKit service.

On-Device Intelligence

Our core intelligent algorithms use cutting-edge cognitive science models running locally on your device to deliver personalized learning experiences. The system builds a high-precision "Dynamic Learning Profile" in real-time to provide millisecond-level personalized recommendations. Your complete learning data is stored in the iCloud private database (encrypted and managed by Apple), accessible only by you. When you actively use cloud AI features, we send only the de-identified text fragments necessary to complete the request for anonymous computation; no identity information is linked.

Voice Evaluation Service

When you use the oral practice feature, AXIOM AI invokes the Neural Engine locally on your device to analyze audio data captured by the microphone in real-time for pronunciation feedback. This process runs entirely offline on your device in a closed loop, involving no network transmission. Audio data is used solely for instant analysis and is immediately released from memory after processing; it is never saved, uploaded to servers, or used to train cloud models.

Improving Learning Experience

We use your learning data to improve App features and user experience, such as optimizing word recommendations and adjusting review intervals. This data is processed only on your device and is not sent to our servers. We do not collect or analyze your personal learning content for the developer's commercial purposes.

Security & Compliance

We use on-device security mechanisms to protect the AXIOM AI runtime environment against malicious intrusion or fraud. Because we adhere to the principle of data minimization and because core data is stored in your private iCloud container or on your local device, your personal information security is protected by Apple's rigorous system-level encryption, which even we as developers cannot decrypt or pry into.

AXIOM AI’s Sharing of Personal Data

AXIOM AI adopts a strict "Stateless" strategy for handling features requiring cloud assistance, and architecturally implements "Identity and Data Separation": only learning fragments necessary to complete requests are sent to the cloud, containing no information that can directly identify you personally. The cloud providers we partner with act solely as computational engines and are prohibited from using these fragments to build user profiles or for long-term storage; we do not provide these providers with account information that can directly identify you, developers cannot pry into your original learning content, and cloud models cannot identify you or your personal information based solely on these fragments.

Generative AI Services

When you actively use features like translation or context generation, we send de-identified text content necessary to complete the request to the cloud via enterprise-grade paid APIs (which may include but are not limited to DeepSeek, Google Gemini, ChatGPT, etc.). Under our enterprise agreements with providers, your Input data and Output content are strictly prohibited from being used to train their AI models or build any form of user profile. Relevant data is used only for the instantaneous computation of the current request and is immediately deleted from the system upon completion, with no persistent storage.

CloudKit Data Synchronization

We use Apple's CloudKit service as our sole data backend. This is not just data sharing, but data hosting: core learning data used for long-term storage actually never leaves Apple's secure ecosystem, existing only in your private iCloud database, with security and encryption managed by Apple. AXIOM AI as the developer can only read and write data through restricted system interfaces and cannot directly view your raw content.

Your Privacy Rights at AXIOM AI

At AXIOM AI, we respect your ability to know, access, correct, transfer, restrict the processing of, and delete your personal data. We provide these rights to our global user base and if you choose to exercise these privacy rights, you have the right not to be treated in a discriminatory way nor to receive a lesser degree of service from AXIOM AI. You have the right to withdraw your consent at any time where you have previously given your consent to the processing of your personal data by AXIOM AI.

You can exercise your privacy rights by:

• Right to Access: View your learning data, favorite records, and flag lists via various pages within the App.
• Right to Correction: Update your nickname and avatar photo in the Settings page.
• Right to Deletion: Delete your account in the Settings page to permanently remove all personal data and learning records.
• Right to Portability: Export corresponding vocabulary as CSV files from flag lists and favorite pages.
• Right to Withdraw Consent: Revoke permissions (e.g., microphone, photo library) in iOS system settings, or turn off sound and haptic feedback in App settings.

Since we rely on the CloudKit private database architecture, your learning data is actually stored in your iCloud account. You can also access or delete your iCloud data via Apple's Data & Privacy portal.

If you have any questions about exercising your privacy rights, please contact us at support@axiommuse.com. You also have the right to lodge a complaint with the applicable data protection authority.

Protection of Personal Data at AXIOM AI

AXIOM AI believes that great privacy rests on a foundation of great security. We use administrative, technical, and physical safeguards to protect your personal data, taking into account the nature of the personal data and the processing, and the threats posed. We are constantly working to improve on these safeguards to help keep your personal data secure.

Our security measures include:

• Using HTTPS encryption for all network data transmission.
• Storing learning data in iCloud private databases (security and encryption managed by Apple).
• Not collecting personal information beyond what is necessary for functionality.
• Processing the vast majority of learning data locally on-device; sending only necessary content in an anonymous, minimized form for computation when you actively use cloud AI features.
• Not storing any user personal data on our own servers.
• Using "Sign in with Apple" to secure your account.

Children and Personal Data

AXIOM AI is designed for users aged 13 and older. We understand the importance of protecting the personal data of minors, so we use the account system provided by Apple to ensure compliance.

Reliance on Apple Family Sharing

We rely entirely on Apple's "Sign in with Apple" and "Family Sharing" mechanisms to handle accounts for minors. If a child under 13 needs to use this App, a parent can create a child Apple ID for them via Apple Family Sharing. Child account creation, parental consent, and privacy controls are managed by the Apple system; we do not collect additional personal information from children at the App level.

Managed Accounts for Education

Educational institutions enrolled in Apple School Manager can create Managed Apple IDs for students. Privacy settings and parental consent flows for these accounts are managed jointly by the institution and Apple, and we adhere to the same data protection principles.

We do not proactively identify or distinguish between child and adult accounts. All user data is protected according to the same standards described in this Privacy Policy. If a parent needs to manage a child's account data or exercise privacy rights, they can do so by logging into the child's account via the App's settings page, or via Apple Family Sharing parent controls.

Transfer of Personal Data Between Countries

AXIOM AI products and offerings connect you to the world. To make that possible, your personal data may be transferred to or accessed by entities around the world for the processing activities described in this Privacy Policy in connection with your use of our products and services. AXIOM AI complies with laws on the transfer of personal data between countries to help ensure your data is protected, wherever it may be.

Your learning data is stored in your iCloud private database via Apple's CloudKit service. According to Apple's privacy policy, your data may be transferred by Apple to Apple data centers worldwide. This cross-border transfer and storage is managed and protected entirely by Apple as a system-level service.

When you use cloud AI features such as translation or voice evaluation, de-identified text or audio fragments necessary to complete the request may be temporarily transferred to third-party provider servers located in other countries/regions. We require all service providers to adhere to strict data protection standards, using these fragments solely for the anonymous computation of the current request and deleting them immediately upon completion, prohibiting their use for model training or user profiling.

Data Retention

AXIOM AI retains personal data only for so long as necessary to fulfill the purposes for which it was collected, including as described in this Privacy Policy or as required by law. We will retain your personal data for the period necessary to fulfill the purposes outlined in this Privacy Policy. When assessing retention periods, we first carefully examine whether it is necessary to retain the personal data collected and, if retention is required, work to retain the personal data for the shortest possible period permissible under law.

Since your learning data is stored in your iCloud private database, the retention of data is entirely under your control. You can delete your account and all data at any time via the App's settings page. Upon deletion, data is permanently removed from your iCloud private database and cannot be recovered.

For data temporarily sent to third-party providers (such as text for translation), this data is used only for real-time computation of the request; per our enterprise interfaces and service terms, such data will not be used to train models or build user profiles and is deleted from the system immediately after service completion, with no persistent storage.

Local Storage Technologies

Similar to cookies on websites, AXIOM AI uses on-device local storage technologies (such as UserDefaults, SwiftData, and filesystem caching) to implement core functionality.

Strictly Necessary Storage

To record your word mastery and save your preferences (e.g., themes, sound effects), we must write this data (including core algorithm model parameters) locally to your device. If this data is cleared, the App won't function properly or progress will be lost.

Performance Caching

To save your data usage and improve loading speeds, we temporarily cache generated audio files or images in your device sandbox. The system may automatically clear these caches when storage is low, or you can clear them completely by reinstalling the App.

Changes to Privacy Policy

We may update this Privacy Policy from time to time. Updated policies will be published within the App and marked with the update date. If we make material changes to this Privacy Policy, we will notify you via App notification or other appropriate means. Continued use of the App indicates your acceptance of the updated policy. We encourage you to review this page periodically for the latest information.
