What local processing means
Choosing an image for conversion is different from publishing it. The Web creative workflow processes it locally and does not automatically make it public. The separate WeChat product has different platform services and is outside this Web-specific explanation.
Why a saved work can disappear
Site data can be removed by clearing storage, browser cleanup or using a temporary browsing session. A different browser, device or domain has separate storage. Save important chart exports before making those changes; a material CSV alone does not preserve the pixel layout.
The website still makes network requests
Cloudflare serves the site and a language endpoint chooses a default language by request country. Normal hosting requests are not the same as uploading your selected picture. Following material-shopping links sends you to third-party stores, some with affiliate attribution.

Common questions
Will my patterns appear on another device?
Not automatically. Work is stored in the current browser and domain. Do not rely on logging into another device to restore it.
Is clearing browser data safe for saved patterns?
It can remove the data used by the work library. Export important work first and verify that the exported files are saved outside the browser.
