0xAlex Check is run by Alex, an individual in Europe. This page explains what the site collects and why.

Contact form

When you send a message, I store your name, email address, the topic you chose, the link you added and your message. I use them only to read and answer your message and to consider your project for a review. I don't sell them, share them or add you to a mailing list.

Messages are stored in a database hosted by Supabase in the EU (Frankfurt). The site runs on Vercel. To stop spam, your IP address is turned into a one-way code that is used only to limit how many messages can be sent; the address itself is not stored.

Visiting the site

The site doesn't use analytics, advertising or tracking cookies. The hosting provider keeps standard server logs for security and reliability.

Your choices

You can ask me to see, correct or delete your message at any time by emailing 0xnull.dev@gmail.com. I delete messages that are no longer needed.

The separate research tool privacy policy covers my private Google Ads research tool.
