What this site collects

This site collects about as little as a website can while still knowing whether anyone read it. No cookies are set, no advertising networks are present, and nothing you do here is sold or shared with data brokers. What follows is the detail, including what changed and when.

Who is responsible

Know Your Mouth operates this site and is the data controller for it. For anything on this page — including a request to see, correct or delete data — write to privacy@knowyourmouth.com.

Analytics

We use Umami, an open-source analytics tool that we host ourselves on our own server rather than handing your visit to a third-party advertising company.

• No cookies are set. Not for analytics, not for anything else. This is why the site has no cookie consent banner — there is nothing to consent to.
• Your IP address is not stored. It is converted into a one-way hash on our server to count unique visits for a single day, and the address itself is discarded.
• No cross-site tracking. Umami cannot follow you to other websites, and does not try to build a profile of you.
• What is recorded is aggregate: which pages were viewed, roughly where in the world the visit came from, screen size, and which site linked you here.

We also do not keep web server access logs for this site, so there is no second copy of your IP address sitting in a log file.

Third parties your browser contacts

Loading any page here causes your browser to make requests to these parties. We are listing them because a privacy page that only mentions the convenient ones is not worth reading.

• Fonts — no longer a third party. This site used to load its typefaces from Google, which transmitted your IP address to Google on every page load. As of 8 August 2026 the fonts are served from this site's own server, so that transfer no longer happens at all. Nothing about the typography reaches Google.
• Cloudflare — provides DNS for this domain and forwards mail sent to our addresses. Cloudflare does not proxy the website itself.
• ClickBank — only if you click the affiliate link on our ProDentim review. At that point you have left this site and their privacy policy applies, not ours. Nothing is shared with them unless you click.
• YouTube — only if you press play on a video. Some article pages carry a still from one of our videos. The still is an image served from this site, so showing it contacts nobody. Pressing play — and only pressing play — loads a player from youtube-nocookie.com. That player then fetches the video, its images and its fonts from other servers run by Google, YouTube’s owner; when we checked, those were googlevideo.com, ytimg.com, ggpht.com, gstatic.com, google.com and googleapis.com. From that moment your browser is talking to Google, and Google sees those requests, including your IP address. YouTube describes that domain as one that does not set identifying cookies until a video plays; pressing play starts the video, so treat YouTube’s own privacy policy as applying from that moment. We cannot see or control what it stores. Nothing else on the page contacts YouTube, and if you never press play, nothing does. Each video also has a plain link to watch it on YouTube instead.

The newsletter

If you subscribe, we hold your email address for the purpose of sending the newsletter, and for nothing else. It is not sold, rented, or shared. Every email carries an unsubscribe link, and unsubscribing deletes the address.

The newsletter is run on Brevo, a mailing provider based in France, so your address is stored and processed inside the EU — there is no transfer to a country outside it. Brevo acts as our processor and does not use your address for anything of its own.

Signing up is double opt-in: we email you a link and you are only added if you click it. That means nobody can put your address on the list without access to your inbox, and it gives us a dated record that you actually asked — which is what the GDPR expects us to be able to show.

The signup form on this site posts directly to Brevo. It loads no Brevo script, stylesheet or font, so nothing about your visit reaches them unless you actually submit the form.

What we never do

• No advertising networks, retargeting pixels, or social media trackers.
• No selling or sharing of personal data. There is no arrangement under which this could happen.
• No fingerprinting, and no attempt to identify you personally.
• We do not knowingly collect anything from children.

Your rights

Under the GDPR you may request access to your personal data, ask for it to be corrected or erased, object to processing, or ask for a copy in portable form. In practice we hold very little: unless you have subscribed to the newsletter or emailed us, we almost certainly hold nothing that identifies you.

Write to privacy@knowyourmouth.com and we will respond within one month. If you are not satisfied, you have the right to complain to your national data protection authority.
