Privacy Policy

Last updated: September 29, 2026

1. General

This policy applies to the API gateway service and website (smart.funkits.cn) provided by HeySmart ("the Service"). We collect as little data as possible — only what is necessary to run and improve the service.

2. What data we collect

  • Account data: registration email, username, and password hash (we never store plaintext passwords). Used for sign-in, authentication and account recovery.
  • Service usage data: API call timestamps, models, token usage, billing records and response status codes. Used for billing, quota control and troubleshooting. We do not store your request bodies or model outputs.
  • Traffic source data: the referrer on first visit, UTM parameters, page paths and coarse-grained device info (browser/OS category). Used to measure which channels bring visits and to improve the product. We do not store your IP address in raw form, use no device fingerprinting, and do no cross-site tracking.

3. How we use data

  • To provide, maintain and safeguard the service (authentication, billing, rate limiting, troubleshooting);
  • To produce aggregated statistics on visits and usage for product and content improvement (aggregate results only);
  • To answer your inquiries when you contact us.

We never sell your data to third parties, and we never use request content for model training.

4. Data storage and protection

Data is stored on servers under our control, protected with access controls and credential encryption. Traffic-source statistics are retained for no more than 180 days, then aggregated or deleted. Account and billing data are retained for the lifetime of the account.

5. Your rights

You can delete or deactivate your account in the console at any time, or contact us via the channels below to request access to, correction of, or deletion of your personal information. After account deletion, billing records required by law and for reconciliation are retained.

6. Contact us

If you have any questions about this policy, open a ticket via the console Ticket Center and we will respond as soon as possible.
