ChallengeSphere Privacy Policy

Effective date: June 26, 2026

This Privacy Policy explains how ChallengeSphere and Ironside collect, use, share, and protect information when you use the ChallengeSphere app or website.

Developer and privacy contact

ChallengeSphere is provided by Ironside. If you have questions, requests, or concerns about this policy or your data, contact us at ironside-dev@challengesphere.com.

Information we collect

  • Account and profile details such as your name, username, email address, phone number, date of birth or age, gender, bio, profile photo, and account preferences.
  • Challenge activity such as challenges you create or join, submissions, proof photos, comments, glories, leaderboards, streaks, followers, following, invites, and reports.
  • Integration data that you choose to connect, including sign-in information and coding platform handles or solved-problem summaries for services such as LeetCode and Codeforces.
  • Device and app data such as device type, app version, push notification token, log data, diagnostics, crash reports, and actions needed to keep the app reliable and secure.
  • Website analytics and interest-list information such as page visits, referral source, approximate device/browser details, waitlist form details you submit, and interactions with app download or interest buttons.
  • Contacts or invite-related information only when you grant permission or use an invite feature. You can deny or revoke device permissions from your device settings.

How we use information

We use information to create and secure your account, show challenges and profiles, process submissions, power followers and following, send notifications, personalize your experience, and provide support.

We also use information to detect abuse, prevent spam or unsafe behavior, debug performance issues, improve app reliability, and comply with legal obligations.

If you join the website interest list, we use your submitted details and basic website analytics to understand demand for ChallengeSphere, contact early users, and improve launch planning.

Photos, submissions, and public content

ChallengeSphere is a social challenge app, so some content is meant to be visible to other users. Depending on the challenge, your privacy settings, and app features, your username, profile photo, submissions, proof photos, comments, rankings, follower lists, and challenge activity may be visible to other users.

Please avoid uploading sensitive personal information in photos, comments, challenge descriptions, or submissions. If you believe content should be removed, contact us at ironside-dev@challengesphere.com.

How we share information

We do not sell your personal information. We may share information with service providers that help us run ChallengeSphere, such as cloud hosting, storage, authentication, messaging, notifications, analytics, crash diagnostics, and customer support providers.

We may also share information when required by law, to protect users and the app, to investigate abuse or security issues, or as part of a business transaction such as a merger, financing, or acquisition.

Security

We use reasonable technical and organizational safeguards to protect your information. No internet service can guarantee perfect security, so please use a strong password and contact us quickly if you believe your account has been compromised.

Data retention and deletion

We keep information for as long as needed to provide ChallengeSphere, maintain security, meet legal obligations, resolve disputes, and improve the service.

You can request deletion of your account and associated data through our account deletion page or by contacting ironside-dev@challengesphere.com. Some content may remain in backups, logs, moderation records, or other safety records for a limited period after deletion. Public content copied, saved, or shared by other users may not be fully removable by us.

Your choices and rights

You can update account details in the app, change notification preferences, disconnect supported integrations, manage device permissions, and choose what you share in challenges and comments.

You can request access, correction, deletion, or export of your personal information by contacting ironside-dev@challengesphere.com. We may need to verify your identity before completing a request.

Children and minors

ChallengeSphere is not intended for children under 13 or the minimum age required in your location. If you are a minor, use the app only with permission from a parent or guardian when required by law. If you believe a child has provided personal information without proper consent, contact us and we will review the request.

International processing

Your information may be processed and stored in countries other than where you live. When we transfer or process information, we take steps designed to protect it according to this policy.

Changes to this policy

We may update this policy as ChallengeSphere evolves. If changes are material, we will provide notice in the app or by another reasonable method. The updated policy will apply from the effective date shown on this page.
