# Part I: Definitions

De-identification: Refers to the technical processing of personal information so that a specific natural person cannot be identified without the use of additional information.
Anonymization: Refers to the technical processing of personal information so that the personal information subject cannot be identified and the processed information cannot be restored.
IP Address: Refers to the Internet Protocol address, a unique identifier assigned to each computer or mobile device connected to the Internet, including the mobile Internet, when accessing a network. Because these identifiers are usually assigned by country or region, IP addresses can often be used to identify the approximate geographic location of the device's network connection.

# Part II: Main Body

# 1. What Information We Collect

1. Information necessary to provide services and ensure secure and stable operation

When you use our products or services, in order to provide accounting, backup and synchronization, membership benefits, troubleshooting, security protection, and other functions, we will collect or process the following information based on the functions you actually use and your authorization status. Some information is processed only when you use account login, payment, backup and synchronization, image upload, or other related network services.

Information Type	Information Fields	Collection Method	Purpose
Device information	Device model, device identifiers such as Android ID, IDFA, IDFV, OAID, etc., and, in Android/HarmonyOS versions, device MAC address and software installation list that may be obtained, subject to system capabilities and the actual collection by third-party services	Obtained through system APIs or third-party SDKs	Account security, payment risk control, service stability assurance, risk control
Network information	IP address, network type, Wi-Fi status	Obtained through system APIs or third-party SDKs	Network connection, security protection, troubleshooting
Crash and performance logs	App crash information, performance data, and other de-identified information	Firebase	Performance optimization and crash repair
Local logs	Operating system version, software version, operation logs	Written locally during App runtime	Used to assist technical customer support in troubleshooting and resolving issues when you actively provide feedback

Please note that if information cannot identify your personal identity either alone or in combination with other information, it is not personal information in the legal sense. When your information can identify your personal identity either alone or in combination with other information, or when we combine data that cannot be associated with any specific personal information with your other personal information, such information will be treated and protected as personal information under this Privacy Policy during the period of combined use.

2. Information necessary to implement additional functions

2.1 In the Android and HarmonyOS versions, we provide account registration and login functions. You may create an account for iCost products or services by email or by using a third-party account, such as WeChat. If you register by email, we will collect your email address and account password or encrypted password credential. If you log in with a third-party account, such as WeChat, we will collect your third-party account nickname and third-party account avatar. After registration, you may choose to modify or supplement your avatar, nickname, and other information. Not providing such information will not affect your use of iCost products or services.

2.2 When providing you with other additional services, in order to provide more convenient and higher-quality products or services and improve your experience, we will collect geographic location information, camera, photo album (image library/video library), device information, and other information authorized by you after obtaining your explicit consent.

2.3 When you use input, paste, copy, and related functions within the App, the App may call system clipboard capabilities to determine whether the clipboard contains text that can be pasted, or to write information that you actively choose to copy to the clipboard. For example, related clipboard capabilities may be triggered when you long-press an input field, use paste, copy a sharing link, or copy a user identifier. We do not proactively collect, store, or upload your clipboard contents.

2.4 When you use the backup and restore function, if iCloud experiences backup exceptions or certain behaviors do not occur as expected, we may, under good network conditions, use cloud storage as an auxiliary storage method to better protect data security. You can manage this function independently in the App settings.

Please be aware that if you do not agree to provide the information corresponding to the above additional functions, it will not affect your use of the basic services of iCost Expense Tracker, but you may not be able to enjoy the service experience brought by those additional functions.

# 2. How We Use Artificial Intelligence (AI) to Process Your Personal Information

To provide intelligent accounting functions, we may use third-party artificial intelligence models to process your relevant information after you actively use or enable specific functions.

1. Intelligent functions triggered through system integrations

When you use services through system shortcuts, system control center, floating buttons, accessibility services, or other system integration methods, such as "Smart Screenshot Recognition", "Smart Voice Accounting", or "Smart Text Accounting":

1.1 Function mode description: For the Smart Screenshot recognition function, if you have enabled "Auto Recognition" or related intelligent recognition configurations, the system will submit screenshot content, page recognition results, or related text content to an AI model for processing. If the relevant configuration is not enabled, processing will only be performed locally or manually, and no AI model will be invoked.

For Smart Voice and Smart Text functions, invoking the function means that you authorize us to use the relevant voice or text content for AI processing to generate bills.

1.2 Information processing flow: In AI processing mode, the screenshot, voice, text content, or page recognition results that you provide or trigger for recognition will first undergo necessary preprocessing, such as speech-to-text conversion or screenshot OCR, and then the relevant text information will be transmitted to a third-party AI model for intelligent analysis.

1.3 Function availability assurance: To help ensure that intelligent accounting functions can resume normally after a system restart or app update, the Android version may, after you have enabled intelligent accounting and auto-start permission, perform necessary function availability confirmation. This confirmation is used only to help maintain the normal operation of this App's related functions and will not be used to associate with, launch, or wake up any third-party App.

2. Intelligent functions used within the App

When you use the "Voice Memo" function within the App, you can create bills by entering voice or text, or by sending screenshots.

2.1 Authorization and processing: When you tap and use the voice input function for the first time within the App, the device system will request microphone permission. Your authorization and use of this function in this scenario means that you understand and accept: to complete accounting, the voice information you subsequently input will, after being converted into text, be processed with the assistance of the third-party artificial intelligence (AI) models described in this policy. Text or screenshot content you provide through this function will also be processed through similar procedures.

3. General instructions regarding third-party AI processing

3.1 Third-party service providers and models: When in the above AI processing mode, the relevant text information will be transmitted to a technical support environment provided by cloud service providers that meet national legal and regulatory requirements, and third-party artificial intelligence model services will be invoked for processing.

3.2 Data protection statement: We undertake that, except for the purposes necessary to implement this function, we will not use your information for other purposes, and we will require service providers by agreement to strictly protect your information.

3.3 Your control: You can control the collection and processing of information by disabling relevant system integration, accessibility, floating button, and other functions or permissions, by turning off relevant AI processing options in the App's function settings, such as "Auto Recognition" related configurations, or by managing microphone, photo album, and other permissions in the device system settings. After you disable them, we will no longer continue processing, but this does not affect processing that has already been carried out based on your prior authorization.

3.4 Statement on result accuracy: Based on the current characteristics of artificial intelligence technology, generated content may be inaccurate or erroneous. The analysis results are for reference only, and we do not provide any guarantee regarding their absolute accuracy or reliability. Please exercise judgment and verify the results when using them.

# 3. How We Use Your Personal Information

We strictly comply with laws and regulations and our agreements with users, and use the collected information for the following purposes:
