Cookies and advertising
We do not set any cookies of our own and we show no advertising. We never sell your data or use it for marketing.
Read aloud only uses voices installed on your device, so the text never leaves your browser.
Cloudflare
The site is delivered through the Cloudflare content delivery network (CDN), which makes pages load quickly and protects the site from attacks. To do this, Cloudflare processes technical information such as your IP address, browser type and the pages you request. Cloudflare may set strictly necessary security cookies, for example to tell visitors apart from harmful bots.
We use Cloudflare Web Analytics to count visits and see which pages are most useful. It does not use cookies or local storage and does not follow you across other websites. We only see totals, such as the number of page views, countries and browser types, never who you are.
You can read more in Cloudflare's privacy policy.
Server logs
Like every website, our servers keep short-lived technical logs (such as the page requested and the time) to keep the site running and secure.
Emailing us
If you email us, we use your email address and your message only to reply to you. We do not use them for marketing, and we delete them when they are no longer needed.
Your rights
You can ask us to see, correct or delete any message you have sent us. Email [email protected] and we will reply as soon as we can.
Changes to this policy
We may change this privacy policy at any time. Changes apply as soon as they are published on this page, and the date at the top shows when it last changed.
