Privacy Policy

Last updated 26 August 2026

Strongcopy collects nothing. It never reads what you copy, writes no files, keeps no logs, and makes no network connections of any kind. The rest of this page explains that in detail, because a claim to collect nothing is easy to make and worth being able to check.

What Strongcopy reads

macOS keeps a counter on the system pasteboard that increases by one every time anything is written to it. Strongcopy reads that counter five times a second and shows the badge when the number changes. It never asks the pasteboard for the item itself, so the text, image, or file you copied is never handled by the app.

To place the badge, Strongcopy also reads the pointer location at the moment of the copy. That coordinate positions the panel on screen and is discarded straight after.

What Strongcopy stores

Nothing. There is no preferences file, no database, no cache, and no log. Choosing Open at Login asks macOS to register Strongcopy as a login item; that registration is held by macOS, and turning the setting off removes it.

Network connections

Strongcopy makes none. It contains no analytics, no crash reporting, no advertising, and no third-party SDKs, and it does not check for updates. Nothing leaves your Mac, because nothing is ever sent.

Data sharing

No data is collected, so none is shared, sold, or disclosed to anyone, including the developer. This applies equally to children: Strongcopy collects nothing from any user, of any age.

Permissions

Strongcopy asks for neither Accessibility nor notification permission. The Mac App Store build runs inside Apple's App Sandbox and requests no sandbox exceptions.

Checking this yourself

Strongcopy is open source under the MIT license, and the clipboard watching is seventy lines you can read in a minute: ClipboardMonitor.swift. The only pasteboard API it touches is changeCount.

This website

strongcopy.mahata.org is served by GitHub Pages. It sets no cookies and runs no analytics or tracking scripts. GitHub records requests to its servers, including IP addresses, as part of delivering the site; that processing is described in the GitHub General Privacy Statement.

Changes to this policy

If this policy changes, the revised version will be posted here with a new date. Every past revision stays visible in the repository history.
