What you can do in Inkpass on the web
The whole unit catalog, not just the 63
399 parks, monuments, battlefields, seashores, memorials and historic sites, grouped into the nine official passport regions exactly the way the blue book is.
Stamp-by-stamp, station-by-station
A park with six stamping stations gets six entries — each with the station name, the date on the dater, the ink colour, a bonus/special-event flag and a note.
Region rings and closest-to-done
A progress ring per passport region plus a banner naming the region you are nearest to closing out, so the next road trip plans itself.
State-by-state coverage
Every state and territory ranked by how much of its passport you have collected, with the fully closed-out ones sealed.
Trip journal
Bundle an outing into a trip — dates, who came, free-form notes — and every stamp collected on it lists under the parks you hit.
Collecting pace and ink mix
A twelve-month bar chart of cancellations collected and a donut of the ink colours filling your book.

Questions
Is the web version of Inkpass free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the Inkpass iPhone app?+
The iPhone app photographs each impression as a real backup of the page. The browser version keeps the written record — station, date, ink, bonus flag and note — but no photo. The bundled catalog is the 399 units the iPhone app ships. There is no way to add a unit that is not in it here. Everything is stored in this browser. There is no account, no sync with your phone and no server copy — export the JSON or CSV backup to move your book.
