A small form.
A clear purpose.
Jianming Duan operates this website and controls the information submitted through its update and reservation forms.
What we collect
We store your email, signup type, optional intended use and price preference, consent version and submission time in Cloudflare D1. We generate a private cancellation token. We do not request recordings or a Block application. When purchasing opens, Stripe will collect payment details on its hosted checkout; this site will store the order ID, email, payment/refund references, amount, consent version and deadline, but no card number. Avoid placing sensitive information in the optional use-case field.
Why and where
We use these details to send the updates you requested, understand intended workflows and contact potential testers. Cloudflare provides website hosting and database processing. Its infrastructure may process data outside your country. We do not sell the list or send it to Block. Order confirmations and refund notices will be transactional and separate from optional release updates. Purchasing remains disabled until sending and refund checks pass.
Security and abuse prevention
The website uses HTTPS and restricts public database access. A daily changing hash derived from your network address is used for submission limits; the application does not store the raw address in the subscription table. Cloudflare may process network and request metadata for service operation and security. We do not install advertising or audience analytics cookies.
Retention and your choices
We review inactive signups after twelve months. Use the private cancellation link shown after a new signup to stop future updates, or email duanjianming1981@gmail.com from the subscribed address to request access, correction or deletion. Cancellation records may remain to prevent unwanted re-enrollment; a deletion request is handled separately. You can withdraw consent without buying anything. Transaction records and refund notices are separate from marketing subscriptions and are retained as necessary for fulfillment, refunds and accounting; contact the seller for a data request.
External links and support
Following a publisher link takes you to that service’s own policies. Email sent directly to our contact address is processed by Gmail. Do not send private recordings or credentials. This site is intended for adults. Material changes to these practices will be described on this page before a new use of signup data.
