How WreathMargin handles your data.

Calculator use

Calculator math runs in your browser. Inputs are sent to WreathMargin only when you choose to save a calculation by email or save it to an account.

Accounts and saved work

When you create an account, WreathMargin stores the name and email address you provide, a one-way hashed password credential, saved product costing models, profitability records, and account-plan information needed to provide the service.

Email and saved links

If you request a saved calculation or product update, WreathMargin stores the submitted email address and relevant calculator payload so it can provide the requested link or follow-up. Private saved-calculation tokens should not be shared publicly.

Analytics and affiliate clicks

WreathMargin uses self-hosted Matomo analytics to understand page and tool usage. Supply-link redirects may record the link, source page, target, a one-way hash derived from the request IP address, and user-agent information. Some supply links may be affiliate links.

Your controls

Signed-in users can download a private account-data archive or permanently delete their account and associated product records from the account data controls.
