Privacy Policy

Last updated: November 3, 2026

The short version: Crimson Sector collects nothing.

No account, no sign-in, no analytics, no advertising, and no tracking of any kind. Your learning activity stays on your device.

01

Overview

This Privacy Policy explains how Crimson Sector handles information when you use the app and visit this website. We designed the app to work without collecting personal information.

02

What we collect

Crimson Sector does not collect personal information. You do not need to create an account or provide your name, email address, or any other identifying details to use the app.

The app includes no analytics, advertising, or tracking tools.

03

Where your data lives

Your custom wheels, experiments, spins, predictions, lesson progress, achievements, and settings are saved in a local database inside the app on your device.

This information never leaves your device through the app and is not sent to us or to anyone else.

04

Network activity

The app works fully offline and makes no network requests. An internet connection is not required to use its lessons, wheels, experiments, or analysis tools.

05

Third parties

The app includes no third-party analytics, advertising services, or software kits. It does not share information with third parties because it does not collect information in the first place.

06

Website and contact form

This website does not use cookies, analytics, or tracking scripts. The contact form is a preview only: it does not transmit or store the information entered into it.

The website loads fonts from Google Fonts. When those fonts are requested, your browser connects to Google's servers, which may receive technical information such as your IP address. Google's own privacy policy governs that processing.

07

Email support

If you choose to contact us by email, we receive your email address and the information you include in your message. We use it only to respond to your request and provide support.

Please do not include sensitive personal information in support emails.

08

Deleting your data

You control the information stored on your device. In the app, open Settings → Your data to reset:

  • lesson and practice progress;
  • experiments and predictions;
  • custom wheels; or
  • all app data.

Deleting the app removes its local data from the device. You can request deletion of a support conversation by contacting us at the email address below.

09

Children's privacy

Crimson Sector is suitable for learners of all ages and does not knowingly collect any information from anyone, including children under 13.

If this policy changes, the new version will appear on this page with a new “Last updated” date. Material changes may also be reflected in the app's privacy information.
