Privacy. What this site counts about a visit, and what it never sees.
What stays in your browser
A figure that takes your photos works on your device. Your photos are never uploaded or saved. The analytics tools learn only that you added photos, and how many: 1, 2 to 5, or 6 or more. They never see what you type into a form.
Tools without cookies
- Cloudflare Web Analytics counts page views and how fast pages load.
- Umami counts visits: the page, the site you came from, your country, your type of device and browser, and the reading events below.
Neither tool sets a cookie or follows you to other sites.
Tools with cookies
- Google Analytics counts the same visits and events, for deeper reports. It sets
_gacookies. Ad features are off. - The X pixel counts visits that came from an ad on X, and sign-ups after them. It sets the
_twclidcookie. When you subscribe on a page where it runs, X receives a one-way hash of your address to count the sign-up.
In the EEA, the UK and Switzerland, these two tools load only after you choose "Allow". Elsewhere they load with the page.
Videos
The talks on the About page come from YouTube. Nothing loads from YouTube until you press play. Then the video plays from youtube-nocookie.com, and YouTube sees your visit as it does on its own site.
The reading events
- How far you read a post, and which parts of a long read you reach.
- Which "Under the hood" blocks you open, and which contents items and links you click.
- Whether you try a photo figure, with your photos or with the samples.
- Whether you send the sign-up form or the contact form, and whether you download the CV.
- Which talk videos you play.
The contact form sends your message and address to my inbox. The sign-up form keeps your address on a list stored with Cloudflare. I use an address only to answer you or to tell you about a new post. To leave the list, write to me through the contact form.
