Privacy policy
Last updated: October 29, 2026
Who runs this site
This site is run by Christian Costa, from Brazil. You can contact us at [email protected].
What information we handle
- Email messages. If you email us, we receive your address and whatever you write, including any file you attach.
- Technical information. This site is hosted on Cloudflare Pages. Cloudflare may process technical information when a page is requested, such as IP address, time, page requested, and browser type. Cloudflare's privacy policy describes how it handles this information.
What we do not use
The site has no accounts, no comments, and no contact forms. We do not run our own analytics tools; the only measurement is the Cloudflare Web Analytics script described below.
Pages load a Cloudflare Web Analytics script for page-view measurement and a Cloudflare script that protects email addresses shown on the page. Cloudflare's privacy policy describes how it handles the information it processes.
How we use information
We use email messages only to reply to you and to handle corrections or removal requests. Cloudflare also receives page-view measurement requests, as described above.
How long we keep email messages
We keep an email only while it is still needed to answer you or to keep a record of a correction or removal request. We review stored emails once a year and delete those that are no longer needed for either purpose.
Sharing
We do not sell personal information. We share it only with the service providers needed to run the site: Cloudflare, which hosts the site, the provider of our email address, and Google, which serves advertising through AdSense.
Advertising
This site shows advertising served by Google AdSense. Google and its partners use cookies and similar technologies to show ads, and may use information about your visits to this and other sites to show ads that are more relevant to you. You can learn how Google uses this information and manage ad personalization at adssettings.google.com. For more information, see how Google uses information from sites that use its services.
For visitors in the European Economic Area, the United Kingdom, and Switzerland, we show a consent message through Google's consent tool before personalized ads are used. You can change your choice at any time through the privacy options link provided by that tool.
Links to other sites
Our guides may link to other companies' tools and websites. Those sites have their own privacy policies. We do not control them.
Your rights
You can ask what personal information we hold about you, ask us to correct it, or ask us to delete it. Write to the email address above. Depending on where you live, you may have other rights under local law, and this page does not limit them.
Changes
We may update this page. The date at the top shows the latest version.
