Terms of Use
Last updated: November 8, 2026
By using the DIYAmount website and app you agree to these terms.
Purchases
Purchases and renewals are handled by Apple. The app is licensed under Apple's standard EULA.
Estimates only
DIYAmount gives material estimates from the numbers you enter and from typical bag yields. Actual yield varies by product, mixing and site conditions. Estimates don't replace engineering advice, building codes or the instructions on the bag. Check your bag and local requirements before ordering.
No warranty
The site is provided "as is". We don't guarantee that it is error-free or always available.
Limitation of liability
To the extent the law allows, we aren't liable for indirect or consequential damages, or for material, labor or project costs that result from using an estimate.

We may update these terms; the date above shows the latest version. Using the site after a change means you accept the new terms.
