Language preference
When you choose a language manually, this website stores a language-preference cookie named site_locale for up to one year. It contains only the selected language.
Display preference
When you choose light or dark mode manually, this website stores the selection in your browser under site_theme. Choosing System removes that saved value, so the website follows your device setting. This preference is not sent to our server.

The quotation helper works entirely in your browser. Information you enter is used to prepare a message and is not submitted to, or stored by, this website.
External services
When you open WhatsApp or your email application, your message is handled by that external service under its own terms and privacy practices.
Analytics and advertising
This release does not use third-party analytics, advertising cookies, marketing pixels, user accounts or a lead-storage database.
