AI data use
Last updated: 25 October 2026
This states how customer material is sent to a model.
Customer drawings are not used to train a StructBy model
There is no training job. A drawing, a question or a draft is stored so the customer can see it again, and it is sent to a model provider only to produce the result the customer asked for. We do not use it to train a model of our own.
What is sent
A question, a draft, extracted text from an uploaded file, and, where a feature reads a page, the page image, are sent to Anthropic on the Messages API. If a route uses an OpenAI model, that call goes to OpenAI instead. When embedding search uses OpenAI, the text to be embedded is sent to OpenAI. When the local embedder is selected, that text is not sent to OpenAI.
Anthropic
Anthropic's Messages API has no per-request switch that stops retention. Anthropic's commercial terms say retained data is not used to train models without permission. Zero data retention for Anthropic is to be confirmed before launch.
OpenAI
We ask OpenAI not to store chat requests. Embeddings are not covered by that request. OpenAI's API data-usage policy is that API data is not used to train models unless the organisation opts in. Zero data retention for OpenAI is to be confirmed before launch.
How long we keep it
| What | How long |
|---|---|
| A file you delete | 30 days, then the object and the row are deleted |
| A project you delete | 30 days after deletion, once its files are gone. The date is recorded at deletion, so a later change to the setting does not move it. Documents stay with the project and are removed with it. They are not copied onto a personal list. A signed check keeps the project for at least 7 years |
| A workspace project another member still uses | Not deleted when one person closes their account |
| An account you close | 14 days, then personal data is erased. What is kept is held under a de-identified account |
| That de-identified record | 7 years, then deleted |
| Product events | 13 months |
The privacy policy states the 14-day and 7-year periods.
A daily job removes what has passed its date.
Taking a copy
Settings, under Legal, asks for a copy of your own projects, documents and their versions, design values, files, questions, StructCheck runs, site assessments and your own audit entries. The download link lasts 10 minutes. The original file is included when it is still in storage. Rendered page images are not. This is not every record the service holds. A workspace owner or admin can ask for that workspace separately. Another member is a display name.
