Data processing
Who handles a draft.
13 October 2026. These are the product rules for processing. They are not legal advice. Plainvoice does not claim a certification, a seal, or a compliance badge.
Plain Voice, part of Prestons Creek Capital, publishes Plainvoice. Write to hello@plainvoice.ai. The site does not print a street address or a registration number.
Plainvoice processes the draft you paste, the phrases you lock, style samples you save, your account email, your plan, and the monthly word count. A paid plan also stores a Stripe customer id. The no-account demo is processed to return a rewrite and is not written to the database. Plainvoice does not train on your text.
Supabase stores signed-in drafts, rewrites, style samples, the word count, and the account email. Plan and billing fields on the profile are not writable from the browser.
Stripe bills Writer and Studio by card. Plainvoice stores the Stripe customer id. It does not store the card number. Free needs no card. Stopping renewal keeps a paid plan through the current UTC month. Unused words are not refunded.
Sign-in is Google, or a link sent to your email. There is no password. If you use Google, Google handles that sign-in.
When a rewrite is sent to the model, the server calls xAI. xAI keeps that API request for about 30 days for abuse review. Zero data retention is not turned on. If the server has no model key, the draft is not sent.
If analytics is enabled, public pages load a cookieless, EU-hosted analytics script operated by Prestons Creek Capital, which counts pageviews without cookies or personal identifiers. It does not set a cookie, does not fingerprint the browser, and does not store the raw IP address.
From the account page you can delete saved drafts, rewrites, and style samples. Deleting text does not reset the words already counted this month.
Questions: hello@plainvoice.ai. The privacy page and the terms use the same rules.
