Copybook saves the text you copy so you can find it again. That text stays
on your computer. It is never transmitted, and the developer cannot see it.
What is stored
When you copy or cut text on a web page, Copybook records:
the text you copied
the address and title of the page you copied it from
the time you copied it
This is written to chrome.storage.local, which lives on your
own computer inside your browser profile. Older clips are deleted
automatically to stay within a fixed storage budget.
Where your clips go
Nowhere. Your clips are never uploaded. There is no account and no server
holding them, nothing is sold or shared, and none of it is visible to the
developer or to anyone else.
Anonymous usage statistics
Copybook does send a small number of anonymous events, so the developer can
see which features are actually used. This is the only thing it ever sends,
and you can switch it off.
What is sent
that the extension was installed, and that the panel was opened
that a copy was captured, roughly how long it was, and which category
it fell into — link, email, code, number, colour or plain text
that a clip was used, and whether it was pasted or copied
that a search happened, and that clips were exported, imported,
deleted or cleared, with counts
a random identifier made when you install, the version, and which
browser
your approximate location — country, region and city — worked out
from the network address the event arrives from, the same way any
website can see roughly where a visitor is
What is never sent
the text of any clip
the address or title of any page you visit or copy from
anything you type, including what you search for
your name, email or any account identifier — there is no account
your precise location: nothing uses GPS or device location
The identifier is random and made on your device. It is not derived from
anything about you or your machine, so it cannot be matched back to you or
joined to any other dataset. Events are processed by PostHog on the
developer's behalf and for no other purpose.
To turn it off: open the panel, click the ⋯ menu and
untick Share anonymous usage. Nothing is sent from then on.
Export files
Choosing Export writes a JSON file to your normal downloads folder. That
file is yours and is not uploaded anywhere. It contains your clip text, so
treat it the way you would treat any file holding things you have copied.
Deleting your data
Delete a single clip with the button on that clip, or remove everything
with Delete all. Uninstalling the extension deletes all of its stored data
along with it.
Permissions, and why each one exists
Storage — to keep your clips on your computer. This is
the only place they are held.
Side panel — to show the history in the browser's side
panel, which is the extension's entire interface.
Scripting — used once, at install, to start watching
tabs you already had open. Without it, copying would do nothing in those
tabs until each was reloaded. It runs only the code included in this
extension.
Access to websites you visit — a copy can happen on any
page, so the script that notices copying has to be able to run on any
page. It reads the text of the copy you just made, plus that page's
address and title. It also notes which text box you last clicked into, so
that selecting a clip can paste into it — it never reads what that box
already contains. It does not read page content or browsing history.
Children
Copybook is not directed at children and collects no personal information
from anyone.
Changes
If this policy changes, the date at the top changes with it. The list of
events above is exhaustive; any future version that sends more than what is
listed there would say so plainly here first.
