Keycap for macOS, by Vista Mobile Limited.

Last updated 29 August 2026.

What Keycap does with your keyboard

Keycap plays a sound when you press a key, so it has to know that a key was pressed. macOS puts that behind the Input Monitoring permission, which you grant explicitly and can revoke at any time.

Here is exactly what happens, and what cannot happen:

• Keycap creates a listen-only event tap. macOS hands it a read-only copy of each key event. It cannot modify, block, swallow or inject a keystroke — the interface it uses provides no way to do so.
• The only value read from an event is the virtual key code: which physical key moved. That number selects one of twelve audio samples, and is then discarded.
• Keycap never assembles characters. It has no text handling of any kind, so it cannot distinguish the letters of a password from anything else you type.
• No keystroke, and nothing derived from a keystroke, is written to disk, kept in a log, or sent over a network. There is no history to leak, because none is ever created.
• Keycap runs inside the macOS App Sandbox, which limits what it can reach on your Mac.

If you revoke Input Monitoring, Keycap keeps working — it simply stops making sound and tells you why.

What is stored on your Mac

Two things, both local to your computer and both removed when you delete the app:

• Your settings — selected switch, volume, whether release sounds are on, launch at login, and the address of the sound library. Stored in the app's own preferences.
• Sound packs you download — audio files, kept in the app's Application Support folder.

None of this is transmitted anywhere, and none of it identifies you.

Network use

Keycap makes network requests for exactly one purpose: fetching the list of available sound packs, and downloading the packs you choose. Those files are public and hosted on GitHub. No account, token or identifier is sent, and no information about you or your typing is included in the request.

To be complete: like any web request, this reveals your IP address to the host serving the files (GitHub), which may record it in its own standard server logs under its own privacy policy. We neither receive nor have access to those logs. If you never open the Library tab and never download a pack, Keycap makes no network requests at all, and the app is fully usable that way.

What we do not do

• No analytics, telemetry, crash reporting or usage statistics.
• No advertising, and no advertising identifiers.
• No third-party SDKs of any kind.
• No accounts, sign-in, email collection or newsletters.
• No selling, sharing or transferring of personal information, because none is collected.

Our App Store privacy declaration is Data Not Collected, and it is accurate.

Purchases

Keycap is a paid download with no in-app purchases. The purchase is handled entirely by Apple. We never see your payment details, and Apple's own privacy policy governs that transaction.

Children

Keycap is not directed at children and collects no data from anyone, including children. It is rated suitable for all ages.

Your rights

Data protection law gives you rights of access, correction, deletion, portability and objection. Because we hold no personal data about you, there is nothing for us to look up, correct, export or erase. If you would like this confirmed in writing, email us and we will reply.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new date. If a future version of Keycap ever collected data — it does not today, and we have no plans for it — we would say so here and ask for your consent in the app before doing anything.
