NômKey does not collect, store, transmit, or sell any personal data. Your keystrokes never leave your device.
The NômKey keyboard may ask for “Full Access” for one reason only: haptic (vibration) key feedback, which iOS does not allow keyboard extensions to produce without it. Granting Full Access is optional — the keyboard is fully functional without it.
Even with Full Access granted, the keyboard extension makes no network requests whatsoever — it contains no networking code and cannot send anything you type anywhere, to us or to anyone else. Converting Telex/VNI to Vietnamese, suggesting Hán-Nôm characters, and swipe typing all happen entirely on your device.
To improve suggestions over time, the keyboard remembers a few things locally on your device only: characters you choose most often, words you pick after swiping, and which characters tend to follow one another. This learning is stored on your device, is never uploaded, and is removed if you delete the app.
Your preferences (input method, display options) are stored locally on your device using Apple’s standard on-device storage.
The NômKey app includes a character browser. When — and only when — you open a character’s detail view, the app fetches that character’s etymology and meaning from the public Wiktionary websites (en.wiktionary.org and vi.wiktionary.org). These requests contain only the single character you are looking up. No personal information, and nothing you have typed, is included. Wiktionary is operated by the Wikimedia Foundation under its own privacy policy.
NômKey contains no analytics, no advertising, and no third-party tracking SDKs. It does not use the Advertising Identifier and does not track you across apps or websites.
NômKey does not knowingly collect any data from anyone, including children.
If this policy changes, the updated version will be posted at this page.
