Every guide on this site belongs to a track, and every track has an order that was chosen for a reason. This page shows how far through each one you are.
How it remembers
In your browser, and nowhere else.
Marking a guide complete writes a single entry to localStorage under one key. There is no account, no email address, no identifier, and nothing is transmitted — not to this site, not to an analytics service. The site records that *a* guide was marked complete, never which browser marked it.
The honest trade is worth stating plainly: because it is stored locally, it does not follow you to another device or another browser, and clearing site data clears it. That is the cost of not asking you to create an account, and it seemed the better side of the bargain for something that is a reading list rather than a qualification.
If you are in a private window, or your browser blocks site data, the controls do not appear at all. A button that pretends to remember and then forgets is worse than no button.
What "complete" means
Whatever you want it to mean. Nothing checks up on you, and there is no certificate at the end.
A guide is marked complete for the whole site rather than per track, so a guide that appears in two tracks is ticked in both once you have read it. Reading it once is reading it once.
Saved for later
Separate from completion, and deliberately so. "Save for later" is for the guide you want to come back to; "Mark complete" is for the one you have finished. Conflating them would make both less useful.
My Projects
Progress is one thing; the work is another. My Projects keeps what this site helps you make for a specific website — generated checklists, audit prompts, lab results, a task list — next to the guides you have read here. The first time you open it, your saved and completed guides are copied across; this page keeps working exactly as before.
