Privacy

Short version: the instant checks and the prompt builder run entirely on your own machine and send nothing anywhere. The optional AI review is the one exception — it sends your prompt to our server and on to an AI provider to be graded and rewritten. We store no prompts and set no cookies of our own. The site is funded by Google advertising, which does set cookies.

What we do with your prompt

The instant checks stay on your machine. The nine checks are JavaScript running in your browser. Your prompt is not transmitted to us for them, and there is nothing to transmit it to — the pages are static files on a CDN. You can verify this: open your browser's developer tools, go to the Network tab, and type a prompt. No request carries it.

The prompt builder stays on your machine too. Building a prompt from the guided questions happens entirely in your browser.

The AI review is different, and this is the part to read. When you click "Get the full review", your prompt is sent — to our own server (/api/review), which forwards it to our AI provider, Together AI, to grade and rewrite. The result comes back to your screen.

• We do not store your prompt or the review. Our server processes the request and keeps nothing.
• Together AI processes the prompt to generate the review, under their privacy terms. We do not send them your name, email, or any account information — we have none.
• Because your prompt leaves your browser for this feature, do not use the AI review on anything genuinely confidential. The instant checks, which never transmit it, remain available for that.

The chat hand-off works by clipboard and a new tab. When you click "Open Claude" or "Open ChatGPT", we copy the prompt to your clipboard and open their site. Whatever happens next is between you and them, under their privacy policy.

What our server keeps

So that the free AI review cannot be abused, our server keeps two short-lived counts — never your prompt:

• Counts of requests per IP address — one that resets every minute, one every day — used only to stop any single source from flooding or draining the service. Both expire automatically.
• A running daily total of all reviews, used to enforce a spending limit.

These are numbers. They contain no prompt text and identify no person beyond a transient IP address used to rate-limit and then discarded.

Cookies and advertising

We show advertisements from Google. That is how the site stays free.

Google's advertising code runs on the pages of this site, including the ones where you type a prompt. Their script is third-party code we cannot audit. As with any web page carrying third-party code, do not paste anything genuinely confidential.

Google and its advertising partners set cookies on this site. They are used to serve ads, to measure whether ads were seen, and — depending on your settings and where you live — to personalise which ads you see.

• If you are in the EU, UK, or Switzerland, you will see a consent banner before any personalised advertising cookie is set. You can refuse, and you can change your mind later.
• You can control or opt out of personalised advertising at any time at Google's Ads Settings, regardless of where you live.
• Google's own explanation of how it uses data from sites like this one is at policies.google.com/technologies/partner-sites.

We set no cookies of our own. Every cookie on this site belongs to Google.

Analytics

We use Vercel Web Analytics, which is deliberately the least invasive option available:

• It is served from our own domain, not a third party's.
• It sets no cookies.
• It creates no cross-site identifier, so you cannot be followed from here to elsewhere.

It records that a page was viewed, roughly what part of the world from, and which anonymous events happened — a check was run, a review was requested, a guide was opened. Those events carry only fixed values: a task type, a rule name, a success-or-failure reason. They never carry your prompt or any part of it. That is enforced in the code rather than by policy: the analytics module accepts only a closed set of values, so there is no way to pass it your text even by accident.

What we store

No prompts, no accounts, no database of your content. The only things our server retains are the short-lived abuse-prevention counts described above. We have nothing to lose, sell, or be compelled to hand over about what you typed, because we never keep it.

Your rights

We hold no personal data about you beyond the transient rate-limiting counts. Google may — see their policies above, which govern what they collect through their advertising. Together AI processes prompts you submit to the AI review under their terms, linked above.

If you believe we hold something about you, get in touch and we will look into it.

Changes

If this policy changes materially, the date below changes with it.
