Privacy and your data

Where your reading is stored, what ever leaves your machine, and how to delete all of it.

Reading along means seeing what is on your screen, which is a serious thing to ask for. This page is the practical side of that: where your reading is kept, what ever leaves your machine, and how to remove any of it. The complete technical account is in How capture works.

Where your reading lives

Everything CogniPage captures is written to a single folder on your own computer:

macOS — ~/Library/Application Support/io.CogniPage.CogniPage
Windows — %APPDATA%\CogniPage\CogniPage

That folder holds the local database (materials, passages, notes, cards, review history), your preferences, the diagnostic logs, and — only if you ever used a watch-along — the downloaded speech model. Diagnostic logs never contain your reading text.

What leaves your device

Text leaves it in exactly two situations, both of which you control:

You use an AI feature

The relevant passage is sent to our backend and our AI provider, solely to produce that one result.

You enable sync

Your materials and progress travel over an encrypted connection so another device can pick them up.

Both require an account. Without one, CogniPage still captures, schedules and lets you review — offline, on that machine only. Your content is never used to train AI models, and it is never sold.

What CogniPage never does

No keystroke logging. It asks only how many seconds have passed since your last input of any kind, to tell whether you are still reading — never what that input was.
No microphone access, ever. It requests no microphone permission at all.
No stored screenshots or page photographs.
No capture of passwords, credentials or payment fields.
No bundled software, toolbars, extensions or advertising.
No changes to your browser, search engine, home page, proxy, certificates or hosts file.
No autostart. It runs when you open it.

The controls you have

To…	Do this
Stop all new capture right now	Settings → Tracking → Track nothing.
Stop capturing one site or document	Find it in Settings → Tracking and block or forget it.
Withdraw a system permission	Turn it off in your OS privacy settings — no need to uninstall.
Delete one thing you read	Delete the material in Materials, or a single passage in its Segments view.
Stop sending anything to us	Sign out. Capture and review carry on locally.
Delete everything, locally and in the cloud	Settings → Developer → Clear all data.
Delete your account entirely	Email support@cognipage.io.

Clear all data cannot be undone.

It permanently deletes your local database rows and, if you are signed in, your synced content on our servers. There is one confirmation step, and nothing after it.

Removing the app as well

See Removing CogniPage for uninstalling and deleting the data folder by hand.
