Cookie Policy
Last updated: August 22, 2026
The Deyin website uses a minimal set of cookies. We do not use advertising or cross-site tracking cookies.
1. What we use
Essential storage — a small local record of your cookie-banner choice so we stop asking. No personal data is included.
Optional analytics — with your consent, anonymous, aggregated page-view counts help us understand which pages are useful. These never identify you individually.
2. What we don't use
No advertising cookies. No cross-site trackers. No fingerprinting. No selling or sharing of visitor data.
3. Managing your choice
You can change your choice at any time by clearing this site's storage in your browser settings; the banner will reappear and you can pick again. Browsers also let you block or delete cookies entirely — the site works fine without them.
4. The desktop app
This policy covers the website only. The Deyin desktop app and CLI do not set browser cookies; their data handling is described in our Privacy Policy.
