The Soap Bench works without an account. Recipes you build while signed out stay in your own browser and never reach a server.
If you sign in, we store your email address (used only to send sign-in codes), your saved recipes, and basic usage counts such as page visits, calculations, and saves. These counts help us see whether the site is useful. We do not sell personal information.
Cookies and local storage. The site uses your browser's local storage to keep your sign-in session, your theme choice, and your unsaved draft recipe.
Advertising. We show ads through Google AdSense. Google, as a third-party vendor, uses cookies to serve ads based on your visits to this and other websites. You can read how Google uses data from partner sites at policies.google.com/technologies/partner-sites and manage ad personalization at adssettings.google.com.
Feedback. Messages sent through the contact page are stored so we can read and answer them, along with the email address you choose to include.
Deleting your data. Use the wizard below to delete your account, your saved recipes, and your usage history in one step. It works right away and there is no waiting period.
