Privacy Policy

Last updated: May 18th, 2025

This Privacy Policy explains how Pioneer Stack LLC ("we," "us," or "our") collects, uses, and protects your personal information when you use any of our mobile applications under the Pioneer Stack brand, including but not limited to terraSTACK, and related services ("Apps").

By using our Apps, you agree to the terms of this Privacy Policy.

Website Mailing List

If you sign up for updates on piostack.com, we store your email address, the form you used and the time you signed up. We use it only to send occasional news about our products. We do not sell or share it. The list is kept in our database provider, Supabase. To be removed, email principal@piostack.com.

Start a project form

If you use the Start a project form on the Site to ask about client work, we store:

• your name and email address,
• what you tell us about your project,
• your timing, if you choose one (this is optional), and
• the date and time you sent the form (created_at).

This is stored in a database run by our provider Supabase, hosted in the United States. The Site can add entries but cannot read them back. We use what you send only to reply to you about your project. We do not add you to the mailing list, and we do not sell, rent or share it for advertising. You can also write to us directly instead of using the form.

To have your inquiry deleted, email principal@piostack.com from the address you used. If we go on to work together, the information needed for that project is handled under our written agreement with you.

Our Apps are not intended for use by children under 13, and we do not knowingly collect personal information from users in that age group. If we learn we've collected data from a user under 13, we will promptly delete it.

However, no system can be 100% secure. You use the Apps at your own risk.
