Is Maccy Safe? A 2026 Security Review

Quick answer: Yes, Maccy is safe for most Mac users. It is open source, stores clipboard history locally, and is designed to run without cloud sync or accounts. The real risks are not malware but the nature of a clipboard manager: it keeps what you copy, unencrypted, on your disk. Used with sensible ignore settings, the risk is small and manageable.

What does « safe » mean for a clipboard manager?

A clipboard manager sees everything you copy: passwords, API keys, bank details, private messages. So « safe » really means four separate questions:

  1. Can I trust the code and the person shipping it?
  2. Does anything leave my Mac?
  3. What does the app store, and where?
  4. What can I do to limit what it captures?

The rest of this review takes them in order.

Can I trust Maccy’s code and developer?

Maccy App is an open-source project hosted on GitHub under the MIT license, created and maintained by Alex Rodionov (p0deje) . Open source does not guarantee safety, but it changes the trust model: you, or a security researcher, can read what the app does, and changes are visible in the public commit history.

Two practical ways to get Maccy Mac:

  • GitHub releases or Homebrew (brew install maccy): free, built from the public project.
  • Mac App Store: a paid listing that supports development .

Whichever you choose, install from the official repository or the App Store listing, not from a third-party download site. Fake « free download » pages for popular Mac utilities are a far bigger real-world threat than the app itself.

Does Maccy send my clipboard anywhere?

Maccy Clipboard is built as a local-first tool. It has no account system and no cloud sync, so your history is not designed to leave your machine. Don’t just take that on trust, though. You can verify it yourself:

  • Check outbound connections with a firewall such as Little Snitch or LuLu while using Maccy normally. You should see nothing related to clipboard content.
  • Read the source for network calls. The one expected category is update checking in non-App Store builds .

An update check is not the same as clipboard exfiltration, but a careful reader should know the difference and confirm it.

What does Maccy store, and where?

Maccy keeps your history in a local database inside your user account’s data. The exact path and storage format have changed between major versions, so check the current location on your own machine . Two facts matter more than the path:

  • It is not encrypted by Maccy itself. If it is on disk, treat it as readable by anything running as you. FileVault protects it when the Mac is off or locked, not from a process already running in your session.
  • It stores what it captures. Anything that reaches the clipboard and is not ignored can end up in history.

This is true of nearly every clipboard manager, and it is the honest core of the risk.

How does Maccy handle passwords?

Well-behaved password managers mark their clipboard writes as concealed or transient so clipboard tools know to skip them. Maccy respects that convention . In practice, that means most mainstream password managers will not leak into your history. Don’t assume it, though. Test it:

  1. Copy a password from your password manager.
  2. Open Maccy with its hotkey.
  3. If the password appears, add that app to Maccy’s ignore list.

Text you copy from a website, a terminal, or a notes app is not marked at all, so Maccy will record it.

Which permissions does Maccy need?

Permission Why it’s needed Risk if granted
Accessibility Pasting the selected item directly into the active app Broad capability (can send keystrokes), so it is worth granting only to software you trust. Revoke it and Maccy falls back to copying only .
Network (outbound) Update checks in direct-download builds Low, and you can block it with a firewall.
Full Disk Access Not required for normal use Don’t grant it.

On recent macOS versions, the system also adds its own clipboard-access privacy controls, which can show a prompt when an app reads the pasteboard in the background . If you see one for Maccy, that is the OS doing its job, not a sign of misbehavior.

What are the real risks?

Risk Likelihood What to do
Sensitive text captured in history Moderate Ignore sensitive apps; clear history regularly; use clear-on-quit.
Another process or user reads the history file Low on a single-user, FileVault-protected Mac Keep the Mac updated; don’t run untrusted software.
Shoulder-surfing via the popup Situational Clear history before screen sharing.
Fake or tampered download Real, but avoidable Install only from the official GitHub repo, Homebrew, or the App Store.
Maccy itself being malicious Very low (open source, public history) Skim the source or watch network traffic if you want certainty.

How to lock Maccy down

  1. Open Maccy → Settings → Ignore and add password managers, banking apps, and any tool where you handle secrets .
  2. Reduce history size so less sits on disk.
  3. Enable clearing on quit if you want history to end with the session .
  4. Clear history before screen shares or demos.
  5. Enable FileVault in System Settings so the database is encrypted at rest.
  6. Restrict updates or network with a firewall if you want zero outbound traffic.

Maccy vs. cloud-synced clipboard managers

The key difference is the threat model. A cloud-synced manager moves your clipboard through someone else’s servers, adding a company, an account, and a network path to trust. Maccy removes those layers, so the remaining risk is local: the disk and your own habits. If you do want sync across devices, that trade is a real one, and Maccy is not designed to offer it.

Verdict

For a tool that sees everything you copy, Maccy’s design is about as conservative as it gets: open code, no accounts, no sync. What it can’t do is keep you from copying a secret in the first place. Treat its history like a notepad on your desk: useful, and best kept short and out of reach of sensitive material.
