Terms of Use

About these Terms

These Terms apply when you access or use the HomDera website, its calculators and published content. They explain the purpose and limits of the information, permitted use of website materials and the responsibilities that remain with each user.

HomDera is an independent online project based in Ukraine. For questions about this Privacy Policy or information submitted directly to HomDera, contact support@homdera.com.

Information and professional advice

Before making an important purchase or starting work, check the actual property conditions, manufacturer documentation and requirements that apply in your location. Seek professional advice when the decision depends on an inspection, technical design or regulated work.

Calculators and estimates

HomDera calculators produce estimates from the values, units and settings selected by the user. The result is only as reliable as the measurements, product information and assumptions entered.

• Check measurements, units and manufacturer information before relying on a result.
• Actual quantities, prices, runtime and equipment performance may differ from an online estimate.
• Calculator outputs are not technical designs, professional quotations or certified specifications.
• Expensive, permanent or safety-critical decisions require an appropriate independent check.

Safety-critical work

Some work cannot be assessed safely through a general article, photograph or calculator result. This includes permanent electrical or gas installations, structural changes, major demolition and high-capacity battery or inverter systems.

• Do not begin work when you do not have the required skills, tools or legal authority.
• Follow manufacturer instructions and the safety rules that apply in your location.
• Use an appropriately qualified professional when work requires inspection, certification or specialist knowledge.

Availability and liability

We take reasonable care when preparing HomDera content, but the website may occasionally contain an error, become temporarily unavailable or contain information that is not suitable for a particular property or product.

To the extent permitted by applicable law, HomDera is not liable for losses caused by using an estimate without checking the entered data, actual property conditions, manufacturer documentation or the need for professional assessment.

HomDera does not control the actions, statements, products or services of contractors, retailers, manufacturers, advertisers or external websites. Nothing in these Terms excludes or limits a right or responsibility that cannot lawfully be excluded.
