It is done on our own server with no cookies and nothing that identifies you, and it respects &quot;Do Not Track&quot;. You can switch it off on the privacy page.</li></ul> https://ordinate2d.com/changelog#v0.7.8 2026-10-30T12:00:00Z <ul><li><strong>Clearer terms:</strong> a short refund policy page, and rewritten terms, privacy statement and marketplace terms.</li></ul> https://ordinate2d.com/changelog#v0.7.7 2026-10-30T12:00:00Z <ul><li><strong>Safer sign-in:</strong> the bot check on the sign-in page is switched on.</li></ul> https://ordinate2d.com/changelog#v0.7.6 2026-10-30T12:00:00Z <ul><li><strong>Safer sign-in:</strong> the sign-in page can now run an invisible bot check before it sends a code by email.</li></ul> https://ordinate2d.com/changelog#v0.7.5 2026-10-29T12:00:00Z <ul><li><strong>Forum moderation:</strong> a moderator can hide or show a whole thread, remove it (the author is told why by email) and move it to another category, besides pinning and locking.</li></ul> https://ordinate2d.com/changelog#v0.7.4 2026-10-29T12:00:00Z <ul><li><strong>Dialogs:</strong> questions that used to appear in the browser's own grey box (deleting a forum post, signing out everywhere, reporting or withdrawing a marketplace item, a moderator's reason for removing or rejecting) now open in a dialog that looks like the rest of the app, light or dark. Escape cancels, Enter confirms.</li></ul> https://ordinate2d.com/changelog#v0.7.3 2026-10-29T12:00:00Z <ul><li><strong>Fixed:</strong> selecting text in a dialog's field and letting go of the mouse outside the dialog no longer closes it.</li></ul> https://ordinate2d.com/changelog#v0.7.2 2026-10-29T12:00:00Z <ul><li><strong>Save:</strong> Save (the button, File → Save and ⌘S) updates the item in My Assets when the scene came from there; any other scene asks once whether to save to My Assets or download a file.

The vertical frame follows the mechanism, not the floor.</li><li><strong>New example:</strong> Warren Truss under a changing load.</li><li><strong>Marketplace safety:</strong> a new author's first item is read by a moderator before it is public; later items and versions are public at once unless something is flagged; a Report button on every item, and items reported by several accounts are hidden until a moderator looks.</li><li><strong>Heavy scenes:</strong> Play and Step now ask before running a scene whose bodies overlap in more than 20,000 pairs, and a run pauses itself when one step takes over a second, so a pile of overlapping bodies cannot freeze the tab.</li><li><strong>Fixes:</strong> a scene file can no longer ask for more solver substeps than the studio offers; the website and marketplace headers fit a phone.</li></ul> https://ordinate2d.com/changelog#v0.6.10 2026-10-26T12:00:00Z <ul><li><strong>Community forum:</strong> plain-text threads and replies in Announcements, Help, Ideas, Show your scene, Bugs and Other.
