How email subscriptions work, and which analytics tools run on the production site.

Email subscription

After you submit an address, you receive a confirmation email. Unconfirmed addresses are not subscribers and do not receive later mail.

Delivery uses Plunk. Subscription data is not sold and is not used for advertising.

Unsubscribe from any message, or email hello@zhanghe.dev to ask for deletion.

Site analytics

The production site at zhanghe.dev loads Google Analytics and Microsoft Clarity for page usage and session replay. Form fields and other sensitive content are masked by default. Admin pages, preview, and local development do not load Clarity.
