This page explains the limits of the content provided by Jiamei Hub ("we", "us", "the site"). By accessing or using the site you confirm that you have read, understood and accepted this disclaimer in full.

1. Calculator results are estimates

• Our calculators for paint, tile, concrete, mulch, sod, gravel, drywall, flooring and roof shingles produce estimates only. They are intended to help you judge quantities before you buy.
• Actual quantities depend on the product brand, application or installation method, surface condition, workmanship, waste and many other factors. Always rely on the values printed on the product you purchase, the manufacturer's technical data, and the on-site judgement of your contractor.
• Our content does not constitute engineering, construction, cost-estimating, financial or any other professional advice, and it does not replace an assessment by a qualified professional. We accept no liability for any loss arising directly or indirectly from use of our calculator results.

2. Accuracy of information

• We make reasonable efforts to keep content accurate and current, but we do not guarantee that all information is complete, accurate, up to date or suitable for your particular situation.
• Formulas, coverage values and waste percentages may change as industry practice or manufacturer data is updated. We aim to keep pace but cannot promise immediate updates.
• Third-party brands, product names and trademarks mentioned on the site are used only to explain coverage or as data references, and belong to their respective owners.

• Some pages contain links to third-party platforms, such as cloud-storage share pages or third-party download addresses.
• We do not host, store or proxy any third-party app installer or copyrighted work file. We only organise publicly available information and point to where it can be found.
• The content, availability, safety, legality and privacy practices of external links are the responsibility of the relevant third party. We do not control them and make no guarantees about them.
• Any risk in downloading, installing or using third-party software is yours. Confirm the source is trustworthy and run your own security checks before installing.
