US Terms of Use
Free browser preview · Updated November 15, 2026
Scope and operator
These terms describe the Obmer free browser preview for users in the United States. The operator is RTK, OOO (ООО «РУСТЕСТКОНТРОЛЬ», abbreviated ООО «РТК»), Russia, tax identification number 6313564172. Contact info@rustestcontrol.ru. The preview is intended for adults planning renovation work. No purchase, subscription, contractor engagement or automatic renewal is created by using the calculator.
What the preview provides
You can enter or import dimensions, view room geometry in 3D, estimate quantities and costs from your own inputs, and download reports. It is a planning tool. It does not currently provide US contractor matching, cloud accounts, automatic retailer pricing, AI designs, payments or native app downloads.
Measurements and estimates
Verify dimensions on site and check the selected product’s coverage, package quantity, installation requirements and available stock. The editor uses the metric units shown on each field; its US unit converter makes explicit conversions. Do not enter square-foot prices in square-meter price fields. USD is the default for new US projects. Changing a currency label does not convert values. Sales tax, shipping, permits, disposal fees and other charges are not automatically included. Missing prices are not treated as a complete quotation.
Construction and safety
The diagrams are not permit-ready plans, stamped engineering documents or proof of building-code compliance. Cable and pipe layouts are conceptual; default metric pipe sizes are not US nominal pipe-size recommendations. They do not determine electrical protection, load capacity, drain slope, venting, structural adequacy or safe excavation. Have appropriately qualified local professionals review plans and work before installation. Applicable state and local rules remain relevant.
Your files and sharing
You retain your rights in your project data. Use only files you are entitled to use or share. This preview stores drafts locally for up to seven days subject to browser storage and cleanup; download backups. You choose whether and with whom to share downloaded files. We do not act as your contractor, purchasing agent or custodian of locally saved files.
Availability and limitations
The preview is provided on an as-available basis and may contain errors or change over time. We do not promise uninterrupted availability, scan accuracy or a particular project result. Verify calculations before relying on them. Nothing here excludes rights or remedies that applicable law does not allow to be excluded, or limits liability where doing so would be unlawful.
Permitted use
Do not disrupt the service, attempt unauthorized access, upload files you have no right to use, or use it unlawfully. Any future paid offering will be presented separately with its price, cancellation terms and applicable agreement.
Privacy and accessibility
Read the US Privacy Notice for this preview’s data practices. Coordinate fields and text reports provide alternatives to direct 3D interaction. The current PDF is image-based; CSV and JSON provide text/data alternatives. If an accessibility barrier prevents you from using a feature, contact info@rustestcontrol.ru and identify the feature and an alternative format you need.
Updates and contact
This page’s date identifies this version. Questions about the preview, errors or these terms can be sent to info@rustestcontrol.ru. Hosting in the United States does not itself establish a US corporation or remove applicable legal requirements.
