Pasteroll

Yes. Pasteroll is open source under the MIT or Apache-2.0 licence, your choice.

No. Your clipboard and history never leave your computer: no account, no sync, no telemetry. Text recognition (Extract text) runs on your computer too. The only things that can use the internet are two optional steps on Windows. The update check is off until you say yes: once a day it fetches a short signed note from GitHub that names the newest version; GitHub sees your IP address and the Pasteroll version, nothing else, and nothing is downloaded. Downloading an update happens only when you click Download and install and confirm.

It is built so that GitHub, the network and anyone who can edit a release page cannot make Pasteroll run something the maintainer did not sign: each release has a signature made with a key kept offline, and Pasteroll checks it, the version and the file's checksum before running anything. There is no paid code-signing certificate, so Windows SmartScreen does not vouch for it,, and whoever holds the signing key could publish an update. The key fingerprints, and what this does and does not protect against, are listed in SECURITY.md.

On Windows from 0.1.0-beta.9, when the update check is on and a newer version exists, the tray menu offers Download and install (Settings has Check for updates now); a single update window shows what is new, and when you click Download and install in it, Pasteroll downloads it with a progress bar (you can cancel), checks its signature and checksum, installs it and starts again, keeping your history and settings. Nothing is downloaded or installed without that click. You can also update by hand: quit Pasteroll from the tray icon and run the new Setup, or extract the new portable ZIP over the old folder. Older beta.7 and beta.8 copies, and Linux, update by hand. If Download and install says that the pasteroll-update folder "is not Pasteroll's update folder" (a leftover from an earlier update, fixed in 0.1.0-beta.17), delete that folder inside your Pasteroll data folder once (it holds only an old installer) or install by hand.

Yes, on Windows in the Complete look (from 0.1.0-beta.11). Press the Multi-paste button beside the filter and click each clip you want, or hold Ctrl and click (Ctrl+Shift+click chooses a range). Then click where they should go, or press Enter: the text clips are pasted one per line, in the order you chose them. To choose from the keyboard, press Ctrl+M, then hold Shift and press Down or Up (or Ctrl with the arrows, Space, or Ctrl+A for all). Hold Ctrl while you click where they should go (or press Ctrl+E) to open options first: what joins them (new line, space, comma, tab or nothing), a list style (plain, numbered, bulleted) and the order, with a preview. Ctrl+C, or right-click and Copy, puts them on the clipboard without pasting. Pictures cannot be joined into text and are left out. The pasted result is also kept in history as one clip with a small badge (not while recording is paused). While Multi-paste is on, or any clip is chosen, the tall card of the clip shown shrinks into a one-line row, so about a dozen rows are on screen; clear the choice and it opens again. While the carousel is pinned open (Windows, from beta.18), the mouse is enough: choose clips, then press Paste. Linux does not have this in a release yet.

Yes: make a clip a favorite (Ctrl+F in the carousel, or the star) and it is kept until you remove it. In the expanded viewer Ctrl+F still finds text, so use the star there. On Windows (from 0.1.0-beta.16, Complete look) favorite clips also show as small square tiles above the list. Click one to paste it, rest the pointer on it for a second to see the whole clip, or right-click it to paste, remove the favorite or give it a colour. The colours are kept in a small file in your data folder that holds only a clip's number and a colour code. Linux does not have the tiles in a release yet. Pins were renamed Favorites in beta.18; existing favorites are kept.

Rolls are separate collections of clips you roll through left and right, with a slide between them (Windows, new in beta.18). Main is your history and new copies always land there; LEFT and RIGHT are built in on either side, and Settings can hide them. Make your own rolls, place each one on the left or right of Main and order them in Settings, and move clips into one with right-click → Move to roll, or name a new roll from the same menu. Settings can also add a Most used roll and an Images roll. Roll with Ctrl+Left / Ctrl+Right, the footer, or the sideways clicks of a tilt wheel; clips in a custom roll are not removed by the limits, and deleting a roll returns its clips to Main.

Yes, on Windows (new in beta.18). Press an empty part of the carousel and drag it; it stays inside the usable area and follows the pointer across monitors. Click the pin in the search bar, or press Ctrl+K, to keep it above other windows while you use them. While it is pinned open, the keyboard and wheel belong to the other window, the wheel over the carousel turns it, and its Paste button pastes into the window in front. The pin button closes it.

In a database on your disk, in %LOCALAPPDATA%\Pasteroll on Windows and ~/.local/share/pasteroll on Linux. A portable.txt beside the executable keeps data in an adjacent data folder instead. Every clip is encrypted before it is written.

Copies that password managers mark as sensitive are skipped, and you can exclude any program by name in Settings. Even so, a clipboard history is a risk worth knowing about, which is why Pasteroll encrypts it and lets you set how much is kept and for how long.

Beta.4 offers experimental native Wayland support on GNOME 46 with a Pasteroll Shell companion. Mouse activation needs an optional administrator-enabled host helper; keyboard mode uses Ctrl+Shift+Space. Mixed-scale display, viewer and editor checks passed on one Pop!_OS setup. Further manual acceptance, including physical mouse-helper, login/lock and suspend checks, is deferred. Other GNOME versions and Wayland desktops are not supported; use an X11 session for the standard Linux packages. There is no macOS version.

For Windows Setup installs, use Settings > Apps > Pasteroll. History is kept unless you choose to delete it. For a Linux archive install, use ./install.sh --uninstall, or sudo ./install.sh --system --uninstall for a system install. Remove the Debian package with sudo dpkg -r pasteroll; its history and settings stay on disk. Quit a portable copy before removing its extracted folder.
