Frequently asked questions
How do I install the browser extension?
On the Chrome Web Store (or Edge Add-ons / Firefox Add-ons) search "Benlai Calendar" and click Add to install. In mainland China, reaching the Chrome Web Store requires a network environment that can access Google services; if that is inconvenient, use the PWA web app on this site directly.
How do I unlock the full version / premium?
Open the extension or PWA, go to the membership center, and subscribe via Paddle checkout. Your entitlement syncs across devices.
Where can I use my subscription?
The full version is available on the Chrome / Edge / Firefox extension and the PWA. The WeChat mini-program uses its own in-app purchase separately.
Refunds
Digital content cannot be "returned", but we offer a full refund within 14 days of purchase, no questions asked. Email benlaicalendar@gmail.com with your purchase email and payment reference. Refunds are processed by Paddle.com, our Merchant of Record.
Time zone & lunar data
Times such as moonrise, moonset and daylight are computed for Beijing time by default; you can switch the time zone in settings. Lunar and solar-term data are calculated astronomically.
Data & privacy
We store only local preferences (time zone, language, membership state). We do not collect personal data or share it with third parties except service providers (Cloudflare hosting, Paddle payments). See our Privacy Policy.
