What Data Does Your Clipboard Manager Collect? A Comparison

Your clipboard manager sees everything you copy — passwords, messages, code, personal information. That makes its data practices one of the most important things to evaluate before you install it.

But most people never check. They download a clipboard manager, grant it accessibility permissions, and assume it’s handling their data responsibly. Often, it is. Sometimes, it isn’t.

Here’s what four popular Mac clipboard managers actually do with your data.

Data collection comparison

Let’s break down each one.

Paste — iCloud sync and telemetry

Paste is a polished clipboard manager with a visual interface and cross-device sync. It’s also the most data-intensive option on this list.

What it collects:

• Clipboard history is synced through iCloud, meaning your copied items are stored on Apple’s servers
• The app includes analytics and telemetry for usage tracking
• Requires an active internet connection for sync features
• Subscription model ($30/year) — your continued access depends on ongoing payment

The trade-off: Paste’s iCloud sync is genuinely useful if you work across multiple Apple devices. But that convenience comes at the cost of your clipboard data living on remote servers. If you copy a password, a confidential message, or proprietary code, it travels through iCloud.

For users who prioritize cross-device clipboard access above all else, Paste fills that need. For users who prioritize privacy, the cloud sync is a dealbreaker.

Maccy — open source and local

Maccy is an open-source clipboard manager that stores everything locally. It’s lightweight, free, and transparent.

What it collects:

• Nothing. No telemetry, no analytics, no crash reporting
• All clipboard data stored locally on your Mac
• Source code is publicly available for anyone to audit
• No network connections required

The trade-off: Maccy is excellent for privacy, but it only supports text. No images, no files, no rich text. If you frequently copy screenshots, design assets, or file references, Maccy won’t capture them. It’s also a simpler interface — functional but not polished.

For text-only workflows, Maccy is a strong, privacy-respecting choice.

CopyClip — local but ad-supported

CopyClip is a free clipboard manager available on the Mac App Store. It stores clipboard data locally, but there’s a catch.

What it collects:

• Clipboard data is stored locally on your Mac
• The app is ad-supported, which means it includes ad network SDKs
• Ad SDKs typically require network access and may track usage patterns to serve relevant ads
• The free version displays ads; a paid upgrade removes them

The trade-off: Your clipboard data itself stays local, but the ad frameworks bundled with the app introduce network connections and potential tracking. You’re not syncing clipboard data to the cloud, but you are running ad network code alongside your most sensitive data. The paid version removes ads, but the ad SDK code may still be present in the binary.

QuietClip — zero everything

QuietClip takes the most aggressive approach to privacy: zero data collection, enforced at the architecture level.

What it collects:

• Nothing. Zero telemetry, zero analytics, zero crash reports
• No network code in the binary — macOS sandbox prevents all connections
• All clipboard data stored locally using SwiftData
• No ads, no tracking, no third-party SDKs
• Under 5 MB — there’s nowhere to hide bloatware

This isn’t a privacy policy. It’s an engineering decision. QuietClip can’t collect your data because it doesn’t have the code to do so. You don’t have to trust a promise — you can verify it by checking the app’s network entitlements in macOS.

Your clipboard manager has access to everything you copy. Choose one that treats that access with the respect it deserves. For a more detailed look at QuietClip’s privacy architecture, see our privacy page.
