Collector Catalog
Reading your catalog…
Connection settings
These are the app's own connection details. They are already set — changing them will stop it working. Only alter them if you are running your own copy against your own Google project.
Catalog what you collect.
A proper catalog for a serious collection — makers, marks, provenance, photographs and what you paid — searchable in a second, on your desk or in your pocket.
New to this? Read how it works first — it takes about five minutes to set up, and you need a Google account.
What it does that a spreadsheet can't
Finds anything instantly
Search maker, item, catalog number or notes across every collection at once, or
narrow to one and sort it.
Photographs that belong to the piece
Several per item, taken straight from your phone or chosen from your photo library,
shown full size and kept for the next time — not squeezed into a cell.
Fields that fit what you collect
A call has no ISBN and a book has no rig mates. Choose what each collection shows,
and add fields of your own.
Built for a collection, not a list
Makers kept once and shared across items, provenance, what you paid against what
it's worth, wish lists and things you've sold kept separate from what you own.
Yours in your pocket
Add it to your phone's home screen and it behaves like an app — at a show, at an
auction, in a barn with one bar of signal.
Prices stay private
What you paid and what it's worth are hidden until you ask for them, so you can
hand someone your phone.
It lives in your Google Drive
Your catalog is an ordinary Google Sheet in your own Drive, with the photographs in a folder beside it — stored by Google, under your account, exactly like your other files there. We keep no copy and run no database: there is nothing on our side to be lost, sold, or broken into.
What signing in allows
Google is asked for one narrow permission, called drive.file. It covers
the files this app creates and any file you hand it through Google's own picker.
It cannot list the rest of your Drive, open documents you have not chosen, or reach
your mail or photos — and you can withdraw it at any time.
Nothing is locked in
Underneath, your records are kept in a plain spreadsheet — not as the thing you use, but so they are never trapped in a format only we can read. Print them, export them, back them up, or hand them to an appraiser, an insurer, or whoever inherits the collection.
Collections that don't match
Calls, decoys, books and advertising are not the same thing and do not want the same fields. Each collection carries its own, you can add fields of your own, and the things you don't own — a wish list, what you have sold — stay out of the count.
