Privacy Policy

Information We Collect

The HCC2D website allows users to generate QR and HCC2D images. Content submitted through the website is processed on the server to generate PNG output. Generated files are stored temporarily on the server for up to 1 hour and are then removed automatically.

When you request an API key through the website, we collect your name, email address, intended use description, and optionally a website or project URL. This information is used to review your request and deliver the key by email. It may be retained for audit and abuse-prevention purposes.

API keys are stored only as a SHA-256 hash. The raw key is shown once at delivery and is not stored in plain form on our servers.

Server and API Logs

To operate, secure, and troubleshoot the website and API, we may log technical metadata such as request timestamps, IP addresses, response status, and basic user-agent information. These logs are used for rate limiting, abuse prevention, security monitoring, and service reliability.

How We Use Information

Information is used only to provide the requested website and API functionality, including server-side generation of QR and HCC2D images, evaluation of API key requests, delivery and management of API keys, and protection of the service against misuse.

Data Sharing

We do not sell personal data. Content submitted to the generator is processed only to generate the requested code image. Information submitted for API key requests is not shared with third parties except when required to operate, secure, or comply with the law.

Security

We take reasonable measures to protect the website and the data processed through it. However, no method of transmission or storage is completely secure.

Your Choices

You may stop using the website at any time. You may also decide whether to submit an API key request and what information to provide in that request.
