Who operates CalcSlope?
CalcSlope is operated by the individual identified in the operator and contact section. CalcSlope is the website brand; it does not describe an incorporated company.
Use the official email for questions about the service or the handling of personal information. The operator is based in Bangladesh; providers may process information in other countries.
Required identification and responsibility
CalcSlope is an independent website operated by MD Abrar Hasan, an individual web developer based in Bangladesh. Official communication and privacy inquiries are handled through [email protected].
This website provides informational geometry tools and educational guides. It does not offer professional engineering certification, building-code licensing, or architectural structural planning. Results must be independently verified for physical construction.
Measurements and engineering limitations
Use rise and horizontal run from the same straight slope, or another supported independent pair. A two-slope calculation solves each side independently and does not assume equal pitches or halve the full span. An inclination alone cannot determine lengths.
Results describe geometry. Geometric rafter length excludes overhangs, cuts, connections and construction allowances. Display rounding and diagrams do not replace accurate measurements. No roof area, material quantity, structural sizing, load assessment, living-area calculation or building-code approval is provided.
Construction and roofing decisions need project-specific checks and appropriately qualified judgement. The existing geometry disclaimer remains available and is part of the service explanation.
Dates and changes
This information may change when the service, providers, purposes or storage practices change. The update date shown above identifies the current text.
Material changes to optional collection will be explained before activation. New consent will be requested where required by applicable law.
