We set no advertising or analytics cookies, and run no trackers. Everything Setsquare stores in your browser is strictly necessary or functional, it makes the tools work and remembers your preferences. Because of that, there is no consent banner to click through; there is nothing non-essential to consent to.
| Name | Type | Purpose | Lifetime |
|---|---|---|---|
ss.theme | Local storage | Remembers light/dark theme. | Until you clear it |
ss.<tool>.doc, cb.*, ds.*, er.* | Local storage | Auto-saves your current diagram/work so it survives a reload. Stays on your device, never uploaded. | Until you clear it or start a new document |
You can clear all of the above at any time from your browser's site-data / cookie settings. Clearing the ss.<tool>.doc keys will discard any unsaved work. Nothing in the list is a third-party cookie, and none of it is shared with anyone.
