By downloading or using SPEC, you agree to these Terms. If you don't agree, please don't use the app.
SPEC is a mobile app that helps interior designers estimate materials (such as drapery, shade, wallpaper, and upholstery yardage) and reference on-site checklists and design guidelines.
This is the most important section of these Terms. Please read it carefully.
SPEC's calculators — including but not limited to the Drapery Calculator, Shade Calculator, Wallpaper Calculator, and Upholstery Estimator — produce estimates only. All output generated by SPEC is intended as a professional starting point and planning aid. It is not a guarantee of material quantity, cost, or suitability for any specific project.
Calculated estimates are based solely on the measurements and specifications you enter. SPEC cannot account for variables including but not limited to: workroom-specific requirements, fabrication tolerances, pattern matching allowances beyond what is entered, installation conditions, or supplier-specific yardage standards.
Before placing any fabric, material, or product order, you must independently verify all quantities with your workroom, fabricator, or supplier. Final yardage and material requirements should always be confirmed by a qualified workroom professional based on actual samples, confirmed measurements, and their specific production requirements.
By using SPEC, you acknowledge and agree that:
If SPEC allows you to save or sync project information, you're responsible for the accuracy of what you enter and for keeping any login credentials secure.
SPEC is currently free to download and use. If we introduce a paid subscription tier in the future, pricing, billing terms, and cancellation details will be presented to you before purchase and added here.
SPEC, its logo, and its in-app content are owned by us. Using the app doesn't give you ownership of any part of it.
SPEC is provided "as is." We work to keep it accurate and available, but we don't guarantee it will be error-free or uninterrupted.
To the extent permitted by law, we are not liable for indirect, incidental, or consequential damages arising from your use of SPEC, including material or cost losses from estimate inaccuracies.
We may update these Terms as SPEC evolves. Continued use of the app after an update means you accept the revised Terms.
