Privacy policy

Tanklessly has no accounts, comments or mailing list. The planners run in your browser: your fixtures, inlet temperature and other inputs are not sent to us.

Our hosting provider may keep standard server logs, such as IP address and the pages requested, for security and reliability.

When you follow a link to a seller, that seller's privacy policy applies, and an affiliate program may set a cookie so a purchase is credited.

Privacy questions: [email protected].
