Calculators and guides

Calculators run in your browser. Entered values and calculated results are not submitted to a calculation service or saved by the tool interface. The website serves application files and reference images.

Images opened in the angle tools are decoded locally. Images and landmarks remain in memory and are not uploaded or saved in browser storage. Downloads are created on your device. Closing or reloading the page clears the measurement session.

Contact enquiries

The contact form sends your name, email, topic, subject and message to a private Cloudflare D1 database for follow-up by RadSetu. Earlier enquiries may remain on our original server. Short-lived, hashed network identifiers are used to limit spam; raw IP addresses are not stored by the contact service. Do not include patient details or medical images. Contact support to request deletion of an enquiry.

Favourites and recent tools

The shared directory saves tool identifiers in this browser, alongside appearance preferences. It does not put calculator values or report text into the favourites or recent-tools list. Clear these lists using the directory's “Clear favourites & recent” control.

Files and exports

Image decoding, measurements and calculations run in this browser. Exports and clipboard copies are created on your device; you control subsequent sharing. These copies are not removed when the page is closed.

Website requests and external links

Hosting and, when used, Cloudflare Tunnel receive ordinary network request information, such as an IP address and requested file path. External method and licence links open the relevant third-party website when selected. Do not include patient identifiers in tool search queries or support messages.

Tool usage metrics

We collect aggregate counts of tool opens, completed operations, exports and technical errors. Event payloads contain only an approved tool identifier, event name and an optional coarse 3D loading-time band. They never include images, filenames, entered clinical values or results. Short-lived hashed network identifiers limit abuse; raw addresses are not saved by this endpoint. Aggregate counts are retained for up to 90 days. Browser performance analytics is provided by Cloudflare.
