Privacy

Privacy policy.

Last updated October 12, 2026

This page explains what information this website collects, why, and what you can ask me to do with it. I'm Michael Casten, a developer based in Negros Occidental, Philippines, and I run this site myself. I handle personal information in line with the Philippine Data Privacy Act of 2012 (Republic Act No. 10173).

The short version

This site has no sign-up, no forms, no cookies, no analytics and no ads. I don't track you or build a profile of you. The only personal information I receive is what you choose to send me when you get in touch.

Browsing this site

The fonts, images and code on this page are served from this site itself, so viewing it does not contact Google or any other third party.

Like every website, the hosting provider that serves these pages may automatically record basic technical details of each visit, such as your IP address, browser type, the page requested and the time. The host keeps these logs for security and to keep the site running. I don't use them to identify you.

When you contact me

If you message me on WhatsApp or by email, I receive your name, number or address and whatever you write. I use it only to reply and to discuss the work you asked about. I don't sell it, share it for marketing, or add you to a mailing list.

I keep these conversations while we're talking or working together, and for a reasonable time after in case you come back to the project. You can ask me to delete them at any time.

WhatsApp (Meta) and my email provider (Google) carry these messages and handle them under their own privacy policies.

The project demos

The demos linked from the Work section are copies of real systems that run entirely in your browser on invented sample data. They are not connected to any real business's data, and nothing you type into them is sent to me or saved on a server.

  • The demos save their sample data and settings in your browser's local storage so they work while you click around. That stays on your device; clear this site's data in your browser to remove it.
  • The demos load their fonts from Google Fonts, so opening one sends a request, including your IP address, to Google.

GitHub activity

The contribution calendar shows public information from my own GitHub profile. It is read when the site is built, not from your browser, so viewing it does not contact GitHub.

Links to other sites

This site links to GitHub, WhatsApp and the websites of projects I've built. Those sites have their own privacy policies, which apply once you leave this one.

Your rights

Under the Data Privacy Act you can ask what personal information I hold about you, have it corrected, ask me to delete it, or object to how it's used. Email me and I'll reply as soon as I can.

If you believe your information has been mishandled, you can also complain to the National Privacy Commission of the Philippines at privacy.gov.ph.

Changes to this policy

If the site starts collecting anything new, I'll update this page and its date before it does.
