coax

Your writing stays yours. Here is exactly what that means.

Most writing tools keep your manuscript on their servers. coax doesn't — and that changes what this page has to say.

Last updated 9 August 2026 · WhyTwo Consulting Ltd

Your manuscript lives in a folder you own, on your own machine and in your own cloud storage if you choose one. coax has no copy of your book. There is no database of manuscripts to breach, sell, or lose.

What coax stores about you

Only what an account needs to work:

What	Why	Where
Your email address and sign-in identity	So you can sign in and get back to your work	Firebase Authentication (Google)
Your beta status — whether you've signed up for updates, applied, or been approved	To run the beta and let you in	Firestore (Google)
Usage records: date, which AI model ran, how many tokens, what it cost, your plan	To bill accurately and show you what you've spent	Firestore (Google)
Payment records	To take payment	Stripe — coax never sees or stores your card details

Usage records count tokens, not words. They record that a request happened and how large it was. They do not contain any part of what you wrote.

What coax never does

Never stores your manuscript. Your chapters, characters and notes are files on your disk. coax reads them to do its job and writes changes back; it keeps no server-side copy.
Never trains on your writing. Nothing you write is used to train any model, ours or anyone else's.
No analytics, no tracking, no behavioural telemetry. coax does not watch how you use it. This is a deliberate product decision, not an oversight — it is why feedback has to be something you choose to send.
No advertising, and no selling or sharing your data with anyone for their own purposes.

The AI part, plainly

coax is a writing coach built on AI models it does not own. To answer a question or draft a passage, the relevant part of your work has to be sent to the company that runs the model.

Who sees your text, and when

Service	What it receives	When
Anthropic (Claude)	The passage, chapter or story documents relevant to what you asked for	Whenever coax answers, reviews, drafts or rewrites
Google (Gemini embeddings)	Short extracts, converted into a numerical form used to find related passages	When signed in, to power recall across your project
Google (Cloud Text-to-Speech)	The text being read	Only when you ask coax to read your draft aloud

These companies process that text to return a result. coax does not send them your whole book — only what the task needs.

Bring your own key

If you supply your own Anthropic API key in Settings, requests go directly from your machine to Anthropic under your own account, and coax's servers are not involved at all.

What the AI writes is marked as the AI's

coax records which words it wrote and which are yours, and keeps that distinction as you edit. That is a craft feature rather than a privacy one, but it matters here too: coax can always tell you what it contributed.

Your choices

Where your files live — your own machine, or iCloud, Dropbox or Google Drive if you connect one. That is your storage, under your account, subject to that provider's terms.
Whether to use the AI at all — the editor works without it.
Whose AI account pays — ours, or your own key.
Updates — if you signed up for updates, every email has an unsubscribe link, and asking us to delete you removes the record.

Your rights

coax is run by WhyTwo Consulting Ltd in the United Kingdom. Under UK GDPR you can ask for a copy of the personal data held about you, ask for it to be corrected, or ask for it to be deleted. Deleting your account removes your sign-in record, beta status and usage history.

Your manuscript is unaffected by any of that — it is on your own disk, and deleting your coax account does not touch it.
