Privacy
How the website handles searches, page visits and contact messages.
Project and contact
World in Stats is an independent data website operated by Martim Abreu. For privacy questions or requests about information sent to us, email [email protected].
Searches and page visits
The application does not require a World in Stats account, collect contact forms. Search matching runs in your browser over the published catalogue. Search terms and comparison selections appear in page URLs and may be retained in your browser history or shared when you copy a link.
Filtering the catalogue runs locally. Opening or reloading a URL sends a request to the hosting service, including the requested URL and any search or comparison parameters in it. Do not put sensitive personal information into search terms or shared links.
Hosting and external websites
The website is hosted on Cloudflare Pages. Serving a page involves processing technical request information, such as the IP address, requested URL and browser request headers. Hosting logs and retention depend on the hosting service and its configuration. External source links lead to websites with their own privacy practices.
Email messages
The contact link opens your email application. If you send a message, your email address, message and any attachments are delivered to the project’s Gmail inbox. Please include only what is necessary to explain your question or correction and avoid sensitive personal information. This website does not submit a contact form on your behalf.
Our contact-email retention policy is to delete resolved correspondence and its attachments within 12 months after the enquiry is closed. A longer period may be necessary for a documented legal obligation or an ongoing dispute; only the relevant material should be retained. This policy is administered by the operator, not by an automatic deletion feature in this website.
Cookies and tracking
The website uses Cloudflare Web Analytics for audience and performance measurement, not advertising. It does not store searches in cookies or local storage. Page URLs may contain search and comparison parameters; do not enter sensitive information. See the Cookies notice for the distinction between application behaviour and hosting services.
Cloudflare Web Analytics
We use Cloudflare Web Analytics to understand visits and page performance and improve the website. Its JavaScript beacon measures page views and browser performance, including loading and Core Web Vitals. Cloudflare describes the service as privacy-first and cookie-free. It does not track visitors across websites. The beacon is enabled through our hosting configuration; no additional analytics component is installed in the application. See Cloudflare’s Web Analytics documentation.
Reports include page paths, referrers and breakdowns such as country, browser, operating system and device type. Cloudflare states that Web Analytics does not log URL query strings. This is separate from the technical requests processed to serve the website.
Google AdSense site verification
The website includes the official Google AdSense script to connect the site to our publisher account for review. Loading it sends a request to Google, including technical request information such as your IP address and browser headers. This is also the AdSense advertising script, not a separate cookie-free verification service. No ad units are configured in the application; automatic advertising and messaging depend on the publisher account settings. See How Google uses information from sites that use its services. Advertising and consent settings must be reviewed before ads are enabled.
Measurement retention
Cloudflare documents retaining unsampled beacon data for seven days and subsequently aggregating it to around 10% of the original volume. Web Analytics reports can be accessed for the previous six months. A reporting window is not a guaranteed deletion deadline for all provider records. We have not confirmed a separate retention period for hosting logs. See Cloudflare’s Web Analytics FAQ.
Operator-specific information
This notice describes the application’s current behaviour. The operator is Martim Abreu. The applicable grounds for processing and the retention arrangements for hosting logs have not yet been confirmed for publication. This is not a complete operator-specific privacy policy. For questions or privacy requests, use the contact email above.
Your privacy requests
You can contact Martim Abreu at the email above to request access to, correction of or deletion of personal information you have supplied. Depending on the applicable conditions, you may also have rights to restrict or object to processing, data portability and withdrawal of consent where processing relies on consent. These rights are not absolute.
You may lodge a complaint with a competent data protection authority. The European Commission’s guide to individual rights explains these rights and their conditions.
Service providers
Consult Cloudflare’s privacy policy for hosting-provider processing and Google’s privacy policy for Gmail. These provider notices do not replace this website’s own obligations. The operator’s applicable international-transfer arrangements and retention settings still need confirmation.
