Does Clip send your clipboard to the cloud?
No. Clip by Zaweba keeps your clipboard history in a local file on your PC, with no account and no telemetry, and it can encrypt that file.

No. Clip by Zaweba keeps your clipboard history in a local file on your own PC. There's no account, no cloud copy and no telemetry. What you copy stays on your computer, and you can choose to encrypt the stored history as well.
For something that sees everything you copy, that's the point.
Why it matters for a clipboard
Think about what passes through your clipboard in a normal day. Addresses and phone numbers. Bits of emails and documents. Account numbers, order references, perhaps a medical note or a contract clause. A clipboard history is, by its nature, a record of private things.
Some clipboard tools sync your history between devices through an online account. That's convenient, but it means your copied text is stored somewhere else. Clip takes the other approach: it stays offline, and the history never leaves the machine.
Where your history lives
Clip stores its history in a local SQLite database in your Windows profile. Pins, snippets and settings are kept locally too. Nothing is uploaded, and there's no sign-in, so there's nowhere for the data to go.
That also means your history survives a restart. With Start Clip when I sign in turned on, it's back as soon as you sign in.
Protecting the file itself
Keeping data local is the first step. Settings > Storage lets you go further and encrypt the history. When it's on, text, payloads, previews, fingerprints, program names and snippets are sealed with Windows DPAPI for your Windows user. Switching encryption on or off converts what's stored and compacts the file, so no plain-text pages are left behind.
Secure delete is on, so deleted items are overwritten on disk rather than just marked as gone.
Keeping things out in the first place
Local storage protects what Clip records. Its privacy rules decide what it records at all.
Content that password managers flag as private is skipped before Clip reads any of it. Clip also keeps a list of excluded programs, which comes pre-filled with common desktop password managers; anything copied in those is ignored entirely. You can add more on the Privacy page, by typing a name or picking from the running programs.
Password managers that run as browser extensions can't be detected, so pause recording while you use one. Pause recording is on the tray menu, it's remembered across restarts, and the tray icon turns grey with a pause mark while it's on.
If you want something gone, delete it from the History page. Clear history removes everything except your pins, and Clear everything removes the lot after a confirmation.
Using it on more than one computer
Because there's no cloud, nothing syncs between computers by itself. Clip also comes for macOS and Linux with the same history file and settings, but each computer keeps its own history unless you move the file yourself.
The short version
Clip by Zaweba is free software that runs offline, without an account. Your clipboard history is a file on your PC, optionally encrypted, with password-flagged content skipped and chosen programs excluded. Nothing is sent anywhere.
