Antikey is a keyboard that turns your speech into neat text. This page explains what happens to your voice and your words.
When you dictate, the sound from your microphone is sent while you speak to Soniox, which turns it into words. The words are then sent to Anthropic's Claude, which tidies them up (and translates them, if you ask). Both act only to do this for you.
If "Use the text box for context" is on, the text already in the box you are typing into (up to about 1,000 characters before the cursor and 300 after) goes with your voice, so names and the topic come out right. It is never taken from password boxes. You can turn it off in Settings.
Antikey's own server passes the tidy-up request to Claude and hands your phone a one-time key for Soniox. It does not keep your recordings or your text.
On your iPhone: your history of dictations, your settings, modes, dictionary and snippets. Delete the app to remove them.
On Antikey's server: for each subscription, how many seconds of dictation were used each month, how many dictations were made, and what they cost, so the fair-use limit can be applied. A subscription is known only by the anonymous number Apple gives it, never by your name or Apple Account.
Typing: what you type on the Antikey keyboard stays on your iPhone. Learning new words for spelling suggestions happens on the phone.
No advertising, no tracking across apps or websites, no selling or sharing of your data, and no account to sign up for.
Subscriptions are handled by Apple. Antikey never sees your payment details.
If this policy changes, this page will show the new version and its date.
