Website privacy and analytics

Optional website measurement

With your permission, this website uses Google Analytics 4 and Baidu Tongji to measure page visits and clicks on App Store links. We use these reports to understand which pages help visitors find the app. An App Store click is not an installation or purchase.

Neither provider is loaded until you allow analytics. Declining leaves the product pages and download links available. You can reopen Analytics preferences in the footer to change your choice. A previous choice covering Google alone does not enable Baidu; we ask again for the updated measurement.

Data and storage

After consent, we configure both services to measure the page address without query parameters or fragments and the referring website’s origin when available. Google receives the page title, language and App Store link position. Baidu receives the page title and a fixed event category and action with the language and link position, such as en:hero.

The providers also process connection and device information used for measurement, such as IP address, browser, device details and visitor identifiers. We do not send copied text, website account credentials, app browsing history, bookmarks or video links from inside the app. Google signals and advertising personalization are disabled; automatic form and outbound-link measurement in Google and automatic interaction-event collection in Baidu are disabled.

Your choice is stored in this browser for up to 90 days. Google Analytics cookies are limited to this website path and expire after 90 days; event-level and user-level retention in that property are set to 2 months. Baidu uses its own visitor cookies and browser storage; their scope and expiry are controlled by its script and can differ from Google’s settings. Both providers may retain reports separately under their policies. Baidu’s dashboard currently states a default data retention period of one year.

Change your choice

Choose Analytics preferences below or in the product-page footer. Declining stops future measurement and removes this site’s Google Analytics cookies and Baidu site-specific cookies and browser storage that this page can access. It does not delete data already received by the providers or third-party cookies on their domains.
