Terms of Service
Last updated: July 26, 2026
Introduction
Welcome to LeafSteep (“we,” “our,” or “us”). These Terms of Service (“Terms”) govern your use of our website at dayoba.com and all associated calculators, guides, and services (collectively, the “Service”).
By accessing or using the Service, you agree to be bound by these Terms. If you disagree with any part of them, please do not use the Service.
Acceptance of Terms
By accessing, browsing, or using LeafSteep, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated by reference.
We may update these Terms at any time. Your continued use of the Service after changes are posted constitutes acceptance of the revised Terms.
Brewing Aids — Taste and Adjust
LeafSteep’s calculators are brewing and reference tools. They apply standard formulas and commonly cited brewing conventions to the values you enter and round results for readability, so a result depends entirely on your input and on the assumptions of a simplified model. Nothing on the Service is professional, nutritional, or medical certification — the caffeine calculator in particular produces a rough estimate, not a laboratory measurement. Taste is subjective; treat every recommendation as a starting point to adjust to your own leaf, water, and equipment.
Description of Service
LeafSteep provides free, browser-based calculators and educational resources, including:
- A steep time and temperature guide by tea type, adjusted for elevation
- A caffeine estimator based on tea type, cup size, leaf dose, and steep time
- A tea-to-water ratio solver for Western and gongfu-style brewing
- A tea tasting wheel and flavor-note finder
- A gongfu multi-infusion brew timer
- A water hardness calculator and brewing guidance
- Guides, explainers, and reference content on tea and tea culture
All tools are provided free of charge. We may modify, suspend, or discontinue any part of the Service at any time.
Your Responsibilities
When using the Service, you agree to:
- Use the tools in good faith for learning, brewing, or personal reference
- Enter values in the correct units and treat results as a starting point, not a fixed rule
- Not disrupt, overload, or attempt to compromise the website
- Respect intellectual property rights
You are responsible for exercising your own judgment and for confirming any result that matters to you, including caffeine estimates, before relying on it.
Accuracy and Disclaimers
While we aim for sound formulas and reasonable conventions, we cannot guarantee that every calculation matches your specific tea, water, or equipment. Results are estimates based on standard methods and the figures you provide, and are rounded for display. LeafSteep makes no warranties, express or implied, including implied warranties of merchantability, fitness for a particular purpose, or non-infringement.
Intellectual Property
All content on this website — text, graphics, logos, tools, calculators, and software — is the property of LeafSteep or its content suppliers and is protected by applicable copyright and other laws. You may use the tools for personal and educational purposes; you may not copy, resell, or reverse engineer them, or remove proprietary notices.
Limitation of Liability
In no event shall LeafSteep or its suppliers be liable for any damages (including, without limitation, a spoiled brew or other losses) arising out of your use of, or inability to use, the Service, even if we have been advised of the possibility of such damages.
Third-Party Links and Ads
The Service may link to third-party websites and displays third-party advertisements. We do not control and are not responsible for their content, and inclusion of a link or ad is not an endorsement. Your use of any third-party site is at your own risk.
Governing Law
These Terms are governed by and construed in accordance with the laws of the United States, and you submit to the exclusive jurisdiction of the courts located there.
