1. What we collect
This is a corporate information and technical-documentation site. We collect data in only three situations:
- Business enquiries you submit: the name, company, contact details and message you leave on ourcontact page. This is used solely to respond to your enquiry. We do not sell, rent or share it with unrelated third parties.
- Referral statistics: when a visit arrives from an AI answer engine or a search-engine crawler, we record the date, the source name, the path visited and the User-Agent string, in order to measure how our content is cited. We do not record IP addresses, set tracking cookies, or build cross-site profiles.
- Delivery and open status of business email: for business email we send, we record whether it was opened and how many times, so we can throttle sending and avoid contacting the same person repeatedly. No IP address or location is recorded. Every message carries one-click unsubscribe, honoured immediately.
This site loads no third-party advertising or analytics trackers (no Google Analytics, no ad pixels). Public pages set no cookies for visitors; a single session cookie exists only in our internal admin backend, for staff sign-in.
2. Retention and deletion
Business-enquiry records are kept for no more than 24 months after the opportunity closes; referral statistics and email-status data retain only the minimum fields needed for aggregation and counting. You may emailmingxin@agentmail.toat any time to access, correct or delete information about you. After verifying your identity we complete the request and reply in writing within 30 days.
3. How we use YouTube API Services
We operate an internal-only publishing tool that uses YouTube API Services to upload our own technical videos to our own YouTube channel (@mingxinstorage). We state its data boundaries explicitly:
- The tool is not publicly accessible: there is no sign-up and it accepts no third-party user logins.
- It is authorised against our own channel only, using the single OAuth scope
youtube.upload, granted by a Google account owned by the company. - We do not collect, obtain or store any other YouTube user's data. We do not read viewer information, comments, subscription relationships or audience data, and we create no derived metrics.
- The only content the tool transmits to YouTube is the video file itself, its title, description, tags, and the required disclosure that the content is AI-generated.
Use of YouTube API Services is governed by theYouTube Terms of Service, and the associated data is handled by Google under theGoogle Privacy Policy. We can revoke the tool's access at any time via theGoogle security settings page; on revocation the stored credentials on our machine are deleted along with it.
4. AI-generated content disclosure
Some articles on this site, and the narration and visuals of our videos, are AI-generated, and this is labelled prominently on the relevant page. Every performance figure comes from a signed or officially issued third-party test report and is never generated by AI. The reports themselves are in theEvidence Library, and the benchmark suite is open source and reproducible.
5. Changes and complaints
If this policy changes materially we will update the "last updated" date at the top of this page. If you disagree with this policy or with how we handle data, emailmingxin@agentmail.toand we will answer you straight. See also ourTerms of Service.
