Terms of use

Plain terms for the site and the app. Reviews and coordination work are agreed separately, in writing, for each project.

Who we are

Undersite. Contact: hello@undersite.app.

Reviews and coordination work

A campus review, ongoing coordination or a team license is agreed in a written quote or contract for that project: scope, price, dates and what we deliver. Where that contract and these terms differ, the contract wins.

The review guarantee

If a campus review finds fewer than 10 conflicts worth fixing, you do not pay for that review. It applies to a campus with at least five utility models between 30% and 90% design, sent in full at the start of the review. What counts as a conflict worth fixing is a conflict with the clearance, cover or design rules agreed for the review that needs a change to a model or a decision from the design team.

What Undersite is, and is not

Undersite checks modelled utilities against each other and against a ground surface, using the rules you set or agree with us. It helps a coordination team find and track conflicts. It does not replace:

• an 811 call and the locates required before any excavation,
• a utility survey or subsurface utility engineering (SUE) investigation,
• the design responsibility and judgement of the engineers of record.

Results depend on the models and surfaces given to it. A model that is wrong, incomplete or out of date gives results that are too.

Using the app

• Use it for lawful work, with models you have the right to use.
• Do not try to break, overload or get around how it works, or to reach other people's shared projects.
• Keep your passcodes and publish keys to yourself. Anyone with a link and its passcode can open what it shares.

Your data and ours

Your models, conflicts and documents stay yours. You give us only the rights needed to do the work you ask for. Undersite, the app, the site and their design are ours.

Warranty and liability

The site and the app are provided as they are, without a warranty that they suit a particular purpose or are free of errors. To the extent the law allows, we are not liable for indirect or consequential loss, such as lost profit, delay or damage on site, and our total liability for the site and the app is limited to what you paid us for them in the 12 months before the claim. Nothing here limits liability that cannot be limited by law. The liability for reviews and coordination work is set in the contract for that work.

Law and disputes

These terms are governed by Polish law. Disputes go to the courts competent for Kraków, Poland, unless a contract for a project says otherwise.

Changes

We may change these terms. The date at the top shows the latest version; continued use after a change means you accept it.
