Terms

Terms of use

Use Havenivo as a planning aid, not as a substitute for project-specific professional advice.

Planning estimates

Calculator results depend on the measurements and supplier values entered by the user. Confirm quantities, coverage, increments, availability, prices, and delivery requirements with the relevant supplier or contractor before purchasing materials.

No professional engineering advice

Havenivo does not provide engineering, structural, legal, or other licensed professional advice. Projects involving safety, drainage, structures, utilities, permits, or code requirements may require qualified local guidance.

Reasonable limitation

Havenivo aims to make its formulas clear, but cannot guarantee that an estimate fits every material, supplier, site, or project condition. Users remain responsible for checking the information used for purchasing and installation decisions.
