1. How We Collect and Use Your Personal Information

We follow the principles of legality, legitimacy, and necessity to collect your information for the following purposes:

(1) Account Registration and Basic Services

  • Credentials: When you register an account, we collect your email address or phone number for account creation, identity verification, and compliance with cybersecurity regulations.
  • Profile Information: You may choose to provide your name and contact details so that we can offer personalized support.

Unless you choose to save it to the cloud “Capsule,” audio streams will not be retained on our servers beyond the processing period.
  • Document Materials: When you upload PPTs, PDFs, or screenshots, we collect the file content. These materials are used only for algorithm analysis, terminology weighting, and key point prediction. These files remain your private property, and we strictly process them within your authorization.

(3) Automatically Collected System and Security Information

  • Log Data: Includes your IP address, browser type, request date/time, and interactions with the website.
  • Usage Data: To optimize product performance (e.g., improving audio capture algorithms for specific learning environments), we collect your device model, operating system, unique device identifiers, time zone, and version information.

2. How We Use Cookies and Similar Technologies

Cookies are small text files placed on your device to enhance user experience:

1. Authentication

Remember your login status to avoid repeated logins.

2. Personalization

Store your language settings, accent filters, or academic terminology preferences.

3. Analytics

In the event of mergers, acquisitions, or bankruptcy, if personal information is transferred, we will require the new entity to continue complying with this policy.

We may disclose necessary information as required by laws, regulations, judicial authorities, or government mandates.

Capsu adopts industry-leading security measures:

1. Encrypted Transmission

SSL/TLS encryption ensures that audio and documents are securely transmitted between your device and our servers.

2. Physical Data Erasure

When you delete data or your account, we perform not only logical deletion but also physical erasure of storage media to prevent data recovery.

For algorithm training or system improvements, we apply strict anonymization to ensure data is completely detached from personal identity.
