Copaky is an independent, open-source keyboard for iOS, built on azooKey (MIT) with credit to the original project. It supports Japanese input (flick and romaji) and English QWERTY with long-press accented characters, plus an offline clipboard history. Copaky is 100% offline: it contains no networking code.

Go to Settings → General → Keyboard → Keyboards → Add New Keyboard, and select Copaky. Then, in any text field, tap and hold the globe key — or tap it repeatedly — to switch to Copaky.

iOS keyboard extensions are sandboxed by default; Apple's Full Access permission is required to read the system clipboard — used by the optional clipboard history — and it also unlocks keyboard haptics and the paste key. Full Access is off by default and entirely optional — without it, Copaky still works completely: typing, Japanese conversion, themes, and everything else, except clipboard history. Full Access or not, Copaky has no networking code at all, so nothing it reads is ever sent anywhere.

Clipboard history is opt-in: turn it on from the Copaky app (it is off by default). Once enabled, a new item is captured only when you tap the capture control in the keyboard's clipboard tab — never automatically or in the background. Pin an item to keep it; anything unpinned is deleted automatically after 7 days. Password and other secure fields are never captured. Everything stays on your device.

That is a system-level prompt from iOS itself, shown whenever any app or keyboard reads the system clipboard — Copaky does not control or generate it. With Copaky, the clipboard is only read after you take an explicit action, such as tapping the capture control, never silently in the background.

iOS always replaces third-party keyboards with the built-in system keyboard in secure text-entry fields (passwords, PINs, and similar). This is a security behavior built into iOS itself, and it applies to every third-party keyboard — not something specific to Copaky.

Japanese (azooKey's kana-kanji conversion), English, and Italian — Italian has its own predictive candidates on the Latin tab, including accented forms and the auto-accent on space, and is on by default on phones whose first system language is Italian. Long-press still types accented Western-European characters (è, é, à, ü, ñ, ç, and more) for languages such as French and Spanish; full predictive input for further languages is on the roadmap.

No. Copaky's App Store privacy label states Data Not Collected, and the app contains no networking code — you can verify this yourself, since it is open source. See the Privacy Policy for details.
