Strutrix Studio Privacy Policy

In short

• Engineering work on your own computer needs no account. Modelling, analysis, steel design, the calculation report and the model files you save on your computer work offline, and nothing about them is sent to us.
• Signing in is optional. Signing in adds cloud projects and opens the Pro features. What you save to the cloud is stored by our service; a model that holds premium inputs (a tapered tube) is saved to the cloud only, never to a local file.
• An AI assistant reaches your cloud projects only if you connect one, with your own account, and can do nothing the program would not do for you. We log what it does, never what it was given.
• No advertising, no analytics, no telemetry, and we never sell information. The program sends us nothing on its own: no usage data, no crash reports, and nothing about where your computer is.

Information that stays on your computer

• Model files you save locally. They are not sent to us unless you save the model to the cloud.
• Settings: theme, units, how the model is drawn, editing tolerances, window layout, and report preferences, including a company name, a tagline and a logo file location if you enter them.
• A sign-in cache, when you sign in, encrypted by Windows for your Windows account alone, so the program can keep you signed in between sessions.
• An error log, written to your Windows temporary folder if the program meets an unexpected error. It stays on your computer unless you choose to send it to us with a support request.

Information we receive when you sign in

• Your account. Sign-in is provided by Microsoft Entra External ID. We receive an account identifier, your name and your email address, and keep them in a profile together with each program's tier and the date its free trial started, the organizations you belong to, and any company name, license number or display name you add.
• What you save to the cloud, and only that: the job's details (project name and number, engineer, client name, address and telephone, site address and coordinates, scope of work, dates), your structures and the versions saved of them, their descriptions, and your client list. A structure saved after an analysis that is still its own carries that analysis's support reactions with it. While a structure is open for editing, the name of the person editing it is shown to others who can open it.
• Searchable descriptions. The description you give a design and the scope of work you give a job are sent to Microsoft's Azure AI service to compute a search index entry for each, so that designs and jobs can be found by meaning. They are the only parts of your cloud projects that are sent there.
• Maps and addresses. When you look at a job's map or search for an address, the program sends the address you type, or the coordinates and the map area, to Esri's ArcGIS location services to find the place and draw the map. Esri handles them under its own privacy statement. The map shows the job's site, not your computer's location.
• An AI assistant you connect. You can let an AI assistant of your own (Claude, for one) work with your cloud projects by signing it in with your account through the cloud's assistant connector. It then acts as you, within what the program does for you: it can list, read and search your jobs and the designs in them, create jobs, create a building frame (saved unrun), and search the User's Manual. What it reads from your cloud passes through the assistant's provider under that provider's own privacy terms, as does everything you tell the assistant; the provider is your choice, not our service provider, and we send it nothing ourselves. We keep a log of each action an assistant takes: your account identifier, the assistant's identifier and name, the action asked for, the job or design concerned, and how it ended. The log never holds the inputs themselves. A design an assistant creates is recorded as created through an assistant.

How we use it

To sign you in; to store, version, restore and share your cloud projects; to hand a saved structure's support reactions to FoundaTrix Studio or PileAxis when you, or someone you share the job with, read them there; to decide which capabilities your account opens; and to answer you when you contact us. We do not use it for advertising or profiling, and we do not sell or rent it to anyone.

Who else can see it

• Your organization: members of an organization you belong to can see the jobs and designs you share with it, and can read a shared structure's reactions in FoundaTrix Studio or PileAxis. Nothing you save is public.
• Our service providers, who process it only to run the service: Microsoft (Entra External ID for sign-in, Azure App Service, Azure SQL Database and Azure AI, in the United States) and, when you use maps or address search, Esri.
• An AI assistant's provider, only if you connect one: what the assistant reads from your cloud passes through that provider (Anthropic, for Claude) under the provider's own terms. The assistant reads on your behalf; we send the provider nothing.
• The law: we disclose information when the law requires it.

How long we keep it

• Cloud projects are kept until you delete them.
• Saved versions of a design are kept for six months.
• Deleted jobs and designs stay in the recycle bin for thirty days, where you can restore them.
• The support reactions saved with a structure are kept until it is next saved or a version of it is restored, which replaces or removes them.
• The log of an AI assistant's actions is kept for 180 days.
• After those periods, old versions, recycle-bin items and log entries are removed when old records are next cleared, which may be some time after the period ends. Write to us if you want something removed sooner.
• Your profile is kept while your account exists. Write to us to have your account and its cloud data deleted.
• Everything on your own computer is yours to keep or delete. Uninstalling the Microsoft Store edition removes its settings and sign-in cache with it.

Security

Information travels to and from our service encrypted (HTTPS). Cloud projects are reachable only through a signed-in session, by you and by the organizations you share with. The sign-in cache on your computer is encrypted by Windows. An AI assistant you connect signs in through the same Microsoft Entra sign-in page as the program, with your own account, and never holds a password of yours.

Children

Strutrix Studio is professional engineering software and is not directed to children. We do not knowingly collect information from children under 13 (or under 16 where the law sets that age).

Your choices and rights

You can use the program without an account at all. If you sign in, you can sign out at any time, and you can delete any cloud project yourself; a model that holds premium inputs can be kept only in the cloud, so deleting it there deletes it. If you connect an AI assistant, you can withdraw its access at any time by removing the connector from the assistant's settings, and you can ask us to revoke it. You can ask us for a copy of the information we hold about you, to correct it, or to delete it. Depending on where you live (for example in the European Union, the United Kingdom or California), the law gives you these and other rights, and we honour them for everyone.

Changes to this policy

We will post any change here, with a new effective date, and describe significant changes in the program's release notes.
