WristAI+ Privacy Policy

Last updated: April 18, 2026

Key statement: WristAI+ is a network-enabled AI assistant app. To provide sign-in, chat, subscription, and iPhone to Apple Watch sync features, we process the data necessary to operate those features. We do not sell your personal information and we do not integrate third-party advertising SDKs.

1. Data We May Process

When you use WristAI+, we may process the following categories of data:

Account information: such as username, email address, and Apple sign-in credentials used to create or access your account.
Authentication data: access tokens and refresh tokens stored securely on your device and, after you sign in, synced to your watch to maintain sign-in state.
Conversation content: your prompts, selected model, web search preference, generated replies, chat titles, and conversation history.
Subscription and purchase data: App Store transaction identifiers, subscription tier, expiration time, and quota information used to validate purchases and provide entitlements.
Local preferences: such as language settings, watch favorites, and certain local usage states.

2. How We Use Data

To provide registration, sign-in, password reset, and identity verification.
To send your prompts to AI services and return responses.
To save and display conversation history, favorites, model information, and quota status.
To sync sign-in state and language preference between iPhone and Apple Watch.
To validate App Store subscriptions, restore purchases, and manage subscription benefits.
To handle errors, protect service security, and keep the app functioning properly.

3. Storage and Transmission

WristAI+ communicates with our backend services over the internet, so relevant input content is transmitted for processing. Authentication tokens are stored in the device Keychain. Some data, such as watch favorites, is stored locally on your device. If you use Apple Watch, sign-in state and language settings are synced between your devices through Apple's WatchConnectivity framework.

4. Third-Party Services and System Frameworks

We use Apple-provided system frameworks for certain features, including:

Sign in with Apple: for Apple account sign-in.
StoreKit: for in-app subscriptions and purchase restoration.
WatchConnectivity: for syncing data between iPhone and Apple Watch.

The current version does not include third-party advertising SDKs and does not integrate cross-app tracking SDKs for advertising purposes.

Regarding AI service data processing: When providing AI chat features, WristAI+ sends your prompt content to AI service providers for processing to generate responses. However, we do not send your personal data (such as account information, device identifiers, or other information linked to your identity) to any third-party AI service providers. We only transmit the question content necessary for the conversation, and communications with AI service providers do not carry any personally identifiable information or identifiers.

5. Children and Teens

If a minor uses the app, we recommend use under parent or guardian guidance. Because the app includes network-enabled AI chat functionality, guardians should supervise account use, submitted content, and subscription purchases.

6. Managing Your Data

You can delete messages, delete conversations, and remove favorites within the app.
You can sign out to clear sign-in state from your device.
When you uninstall the app, locally stored device data is typically removed by the system.

7. Changes to This Policy

If our data practices, feature scope, or use of third-party capabilities changes in the future, we will update this page. For material changes, we may also provide an in-app notice.
