Terms of Use
Last updated: 2026-06-15.
Acceptance
By using SourdoughHydration you agree to these terms. The site is free, requires no account, and is provided for personal, informational use. If you do not agree, please do not use the site.
Guidance, not guarantees
The calculators and reference pages are educational tools that compute baker's-percentage math and summarize commonly-cited technique and ingredient data. Results are guidance only. Flour absorbency, ambient conditions, and individual equipment vary — always use your own judgement and adjust as you bake.
Food safety
Content here does not replace authoritative food-safety guidance. For fermentation, preservation, and any safety-sensitive step, follow primary sources such as the National Center for Home Food Preservation and your local food-safety authority. You are responsible for the safety of anything you make.
Affiliate links
Some outbound product links are affiliate links: as an Amazon Associate, SourdoughHydration earns from qualifying purchases at no extra cost to you. Affiliate links are marked and never change the price you pay. We link only to gear we consider genuinely useful; we do not display prices (they change) and make no representations about third-party products or merchants.
Advertising
The site may display ads via Google AdSense. See our Privacy Policy for how advertising cookies and personalization work and how to manage them.
Intellectual property
Site content, layout, and original data compilations are © SourdoughHydration. You may quote or cite pages with attribution and a link. Do not scrape, republish, or mirror the site wholesale without permission.
No warranty & limitation of liability
The site is provided "as is", without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, or uninterrupted availability. To the maximum extent permitted by law, SourdoughHydration is not liable for any loss or damage arising from use of the site, its calculators, or any linked third-party site.
Changes
We may update these terms; the "last updated" date above reflects the current version. Continued use after a change constitutes acceptance.
Governing law & contact
