This policy describes how the Stack 21 app for iPhone, version 1.0, handles information. It also describes, separately, how this website handles information. Stack 21 is published by Doleman Enterprises LLC.

Information stored on your device
Game information, such as your high score, is stored locally on your device so the app can show it to you. It is not sent to us.

Selling and sharing
Stack 21 does not sell or share personal information, because the app does not collect personal information.

This website
This website is separate from the Stack 21 app. Nothing described in this section happens inside the app.
Hosting and security
This website is delivered through Cloudflare, which provides hosting, delivery, and security services for it. When you visit, Cloudflare processes technical information about the request, such as your IP address, browser and device type, the page requested, the referring page, and the date and time. This is used to deliver the pages, protect the site from abuse, and keep it running reliably. Cloudflare's security services may set a cookie where one is needed for security.
Performance measurement
Separately from hosting and security, this website uses Cloudflare Web Analytics, also called Real User Measurement, to measure how the site performs for visitors, such as page load times and which pages are viewed. It works through a small script loaded from Cloudflare. According to Cloudflare's documentation, this script does not store or access cookies, local storage, session storage, IndexedDB, or other browser storage. We use these measurements to operate and improve the website. We do not use them for advertising, and we do not sell them.
Not connected to the app
The Stack 21 app does not contain website analytics, and we do not use website analytics to track activity inside the app.
Advertising
This website does not show advertising.
Contacting us
If you contact us for support, we receive whatever you choose to send, such as your email address and your message. We use it only to respond to you.
