We do not keep your messages

What happens to your text

When you press the button, the text you typed goes from your browser to our server, and from there to the language model that produces the rewrite. That is the only reason it travels at all.

It is not written down anywhere, neither what you typed nor what came back. Once the answer is on screen, both are gone from our side.

The two cookies

mic_device holds a random identifier with no meaning attached to it. It counts the free rewrite and finds your credits. It lasts a year.

mic_session only exists once you sign in, and holds nothing but a session id. It lasts two months, and disappears when you sign out.

That is all of them. No advertising cookie, no third-party tracker, and therefore no banner to click.

What we keep in the database

Your IP address, hashed with a server-side salt. The hash recognises a visitor who keeps going; it does not say where you are. The address itself is never stored.

Usage metadata: timestamp, direction, tone, requested language, number of characters. Never the content.

If you buy credits: the email address Stripe passes on, your balance, and a record of the purchase, which also serves as an accounting document.

If you create an account

The account is created after payment. The free rewrite never asks for one, and it exists so your balance does not depend on a cookie.

We then keep your address, a fingerprint of your password computed with scrypt (the password itself is never stored and cannot be read), and your choice about emails.

The box for receiving emails is unchecked by default and separate from everything else. You can change your mind by writing to us, and every send carries an unsubscribe link.

The extension

Your account has a key, shown on your Account page. The extension keeps it on your computer and sends it with each rewrite, because a session cookie does not travel that far.

That key spends your credits, so keep it to yourself. Write to us to revoke it; doing so does not sign you out of the site.

Inside Gmail the extension reads the message field at the moment you click, nothing else, and nothing leaves without that click.

Payment

Payment is handled by Stripe. No card data passes through our servers and we never have access to it.

Analytics

If audience measurement is enabled on this deployment, it is cookie-free and aggregate: page views, clicks, funnel steps. Never the text you type, never what comes back.

No advertising pixel, from Meta or from Google.

Who sees what

The model provider sees your text for as long as it takes to produce the rewrite. The call is made from our server, so no API key ever reaches your browser.

Stripe sees your payment and your email address. Our email sender sees your address when we send a recovery or confirmation link. The server host sees traffic, as any host does.

Nobody else. Nothing is sold, nothing is shared for advertising.

How long

The abuse counters expire on their own within hours or days.

Usage rows and purchase records are kept as long as accounting and support need them, then deleted.

The cookies last a year for the device, two months for the session.

Your rights

You can ask for access, correction or deletion of anything about you, and for your account to be closed, by writing to contact@polstudio.fr. The account email is the only handle we have.

The wall of examples

Every before-and-after on this site is written by us. No visitor message has ever appeared there and none ever will without explicit, separate consent.

Children

This site is not aimed at children. The language on the homepage should make that self-evident.
