Your notes go blank when you look away.

oofPad protects against:

• other people reading the window when you have switched away;
• screen sharing, screenshots and recordings, when Hide the Window from Screen Capture is on, including its menus and dialogs;
• someone reading the saved session from disk: unsaved tabs are stored encrypted for your Windows account, or under your password when you set one.

It does not protect:

• text on screen while you are working in the window;
• a screen share made on another computer: when oofPad runs in a remote session, the computer you connect from captures that session as a picture;
• the program's memory while it runs, or other programs running under your Windows account, which can read the text through Windows' accessibility features, also while it is hidden;
• files you save yourself: those are ordinary text files.

Without a password, unsaved tabs are encrypted for your Windows account. With one (Set Password in the menu), they are encrypted under it (Argon2id and AES-256-GCM), and oofPad asks for it at start, and optionally again after the text was hidden for a number of minutes.

• There is no way to recover a forgotten password. "Forgot It..." at the password prompt starts oofPad empty and keeps the old data aside as backup files, in case the password comes back to you.
• Files you saved yourself are never affected; the password only covers oofPad's own session.

oofPad is one signed program file. Start it from anywhere, a USB stick or your Downloads folder, and it runs. If you want it in the Start menu, choose Install oofPad... in its menu: it copies itself to your user profile, adds a Start menu entry and an entry in Settings > Apps to uninstall it. No administrator rights are needed.

• Either way, settings and tabs are kept in %APPDATA%\oofPad on the computer you use it on.
• To update an installed oofPad, run the new version and choose Update Installed oofPad....
• For a rollout: oofpad.exe --install --quiet installs without any window, --uninstall --quiet removes it again; the exit code is 0 on success.

oofPad contacts guilderworks.com only to check for updates, and only if you allow it. It asks once, at first start, and you can change your answer in Check for Updates.

• The check downloads a public list of versions and compares it on your computer. Nothing about you, your computer or your notes is sent. As with any web request, the server sees the IP address the request comes from.
• It runs at most once a day. oofPad never downloads or installs anything by itself; when there is a newer version, it opens a window that links to the updates page.
• For a rollout, an administrator can answer the question in advance by setting the value UpdateCheck to on or off under HKCU\Software\GuilderWorks\oofpad.

oofPad has no account, no telemetry and no activation. Your notes stay on your computer. The only contact with guilderworks.com is the update check above, if you allow it.
