Information not collected
Meimay does not use access analytics and does not send usage activity, answers, chemical names, or chemical structures to an operator analytics service. No account is required.
Information stored on this device
Learning history, mistake review, display settings, and Mechanism Studio recovery data are stored in the current browser. They are not automatically synchronized across devices.
External communication
Normal learning features do not submit user answers; they only load published learning content. If the user explicitly performs an external name or SMILES lookup in Mechanism Studio, the entered search term may be sent to that search service.
Deleting data
Browser data can be removed with feature reset controls or the browser’s site-data controls. It can also be lost when browser data is cleared, a device fails, or a private-browsing session ends.
Saving and export
Mechanism Studio keeps local recovery data while you work. Completed drawings can be exported to the user’s device as PNG. Meimay does not provide operator-hosted cloud project storage.
