Privacy Policy
Last updated October 15, 2026
Who we are
GlintAd (glintad.yuanasi.com) is run by Shenzhen YuanASI Technology Co., Ltd. ("we", "us"), Room 276, North 2F, Building 23, Keyuan West, No. 1 Kezhi West Road, Keji Yuan Community, Yuehai Street, Nanshan District, Shenzhen, Guangdong, China. We decide how the data described here is used. Contact us about anything in this policy at co@yuanasi.com.
GlintAd is currently a demand test: a free video check and a waitlist for a paid product we haven't built yet.
What we collect, why, and how long we keep it
| Data | Why | Where and how long |
|---|---|---|
| Your video file | To run the check | Never uploaded. Your browser reads the file information and samples frames on your device. |
| Still frames (one per second, small JPEGs, plus sharper copies of up to 8 of them for comparing the product), the audio track, and any product photos you add | To produce your report | Sent to our check service and passed to an AI model provider for that one review. We don't write them to storage; they're discarded as soon as the report is built, or immediately if processing fails. |
| Your report: the results text and up to 6 small thumbnails of frames used as evidence | So you can open and share the report link | Cloudflare R2, at a link that can't be guessed. Deleted after 30 days, or right away when you press "Delete report". |
| Answers on the check form (placements, which parts used AI, optional brand name, category, size, feature title) | The rules depend on them | Used for the review. The report keeps only the results they led to, for its 30 days. Our usage log keeps the placements, which AI boxes you ticked, the video's length, file type and size, and how many product photos you added. |
| "Wrong?" feedback: the report and check it's about, what the report said, your optional note | To find and fix wrong results | Cloudflare D1, 90 days. Screenshots only if you tick the box, deleted after 30 days. |
| Waitlist: email address, chosen plan, and the optional questions (where you sell, monthly ad spend, a link to an ad you'd want yours to be like) | To email you about GlintAd if we launch. The optional answers help us decide what to build; we don't open the link automatically. | Cloudflare D1, until you unsubscribe or ask us to delete it. If we stop the test, we'll email you once and delete the list within 30 days. |
| Usage events: for example "check started", "check completed", pricing clicks, which page, and the campaign tags (UTM) in the link you arrived from | To measure whether the test works | Cloudflare D1, 12 months. No IP address, no cookies, no device or browser ID. |
| Your IP address | Only to limit free checks to 5 per day | Stored as a keyed hash that changes every day, never as the address itself, and deleted after about 24 hours. |
| Page views | To see which pages and sources bring visitors | Cloudflare Web Analytics, which counts visits without cookies and without identifying you. |
We don't use cookies, and we don't store tracking IDs in your browser.
AI review and training
Frames, audio and product photos are reviewed by AI models we reach through OpenRouter: Alibaba's Qwen, and Z.ai's GLM as a backup. We ask OpenRouter to route only to providers that don't train on the data they receive, and we don't use your content to train models ourselves. A model provider may keep a request for a limited time under its own terms, for example to detect abuse.
Who processes data for us
- Cloudflare: hosting, the check service, database (D1), report storage (R2) and Web Analytics.
- OpenRouter, and the model provider it routes each review to: the AI review.
- An email delivery service, if we email the waitlist. We'll add it here before we do.
Where data is processed
Our company is in China. The services above run in the United States and other countries where Cloudflare and the model providers operate. Your data is not stored on servers in China.
Your choices and rights
- Delete a report at any time with the "Delete report" button on it.
- Ask us what we hold about you, to correct it, or to delete it, and unsubscribe from the waitlist, by emailing co@yuanasi.com from the address you signed up with.
- Joining the waitlist is optional and based on your consent; you can withdraw it at any time. Rate limiting and usage measurement rely on our legitimate interest in keeping the free check available and knowing whether the test works.
- If you're in the EU or UK, you can also complain to your data protection authority.
Children
GlintAd is for businesses and isn't meant for anyone under 18.
Changes
If we change this policy, we'll update the date above. If a change affects how we use your email, we'll tell the waitlist first.
