Privacy Policy

Last Updated: August 21, 2026

1. Introduction

Third Half, Inc. ("we," "us," or "our") operates the Sideline mobile application. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our application.

2. Information We Collect

Personal Information

We may collect personal information that you provide directly to us, including but not limited to:

  • Name and username
  • Email address
  • Profile information
  • User preferences and settings

Usage Data

We automatically collect certain information about your device and how you interact with our application, including:

  • Device information (model, operating system)
  • App usage statistics
  • Log data and analytics

YouTube API Services

Sideline uses YouTube API Services to help display YouTube videos, channels, metadata, thumbnails, and other YouTube content in the app where those features are available. By using Sideline features that include YouTube content, you also agree to be bound by the YouTube Terms of Service.

When Sideline uses YouTube API Services, we may access, collect, store, and otherwise use limited YouTube API data such as video IDs, channel IDs, titles, descriptions, thumbnails, publish dates, playback/embed availability, and related public metadata. If you connect a Google or YouTube account through OAuth, we may also process authorized YouTube account data only within the scopes you approve on Google's consent screen.

Our use of information received from YouTube API Services is also subject to the Google Privacy Policy. Sideline does not request, collect, or store your YouTube login credentials.

Cookies, Device Storage, and Similar Technologies

Sideline and third parties that provide services to us may store, access, collect, or recognize information directly or indirectly on or from your device or browser. They may do this through cookies, mobile software development kits (SDKs), local storage, caches, pixels, device or app identifiers, and similar technologies.

These technologies may store or access authentication and session information, OAuth state, an anonymous installation ID, a push-notification token, app preferences, cached content and metadata (including YouTube content and metadata), analytics identifiers, and device, browser, network, and usage information. We use them to keep you signed in, remember settings, provide and secure Sideline and its YouTube-related features, deliver notifications, diagnose problems, prevent abuse, and understand use of our services.

Our service providers may collect this information on our behalf. In particular, Google Analytics may place or access cookies and similar technologies on our website. When a YouTube player or other YouTube content is loaded or used in Sideline, Google and YouTube may directly place, access, or recognize cookies, identifiers, or similar technologies on your device or browser and may receive device and browser information, IP address, and activity relating to that content. Google's collection and use of this information is governed by the Google Privacy Policy and its information about cookies and similar technologies.

You can control cookies through your browser settings and certain identifiers, permissions, and local app data through your mobile operating-system settings. You can also use the Google Analytics opt-out described below and revoke Google or YouTube account access as described in Section 5. Blocking technologies required for authentication, security, preferences, or media playback may cause parts of Sideline not to function properly.

Android Age Signals

On Android, we may receive limited age-related signals from Google Play where required by applicable law or platform rules. These signals may include an age range, an age verification status, and, for supervised Google Account installs, a Play-generated install ID used for revoked approval compliance.

We use Google Play age-related signals only for legal compliance and age-appropriate experiences. We do not use these signals or install IDs for advertising, marketing, analytics, profiling, personalization, or general user identity.

Website Analytics

Our website uses Google Analytics, a web analytics service provided by Google LLC. Google Analytics uses cookies and similar technologies to collect information about your use of our website, including:

  • Pages visited and time spent on pages
  • Browser type and version
  • Device type and screen resolution
  • Geographic location (country/city level)
  • Referral source (how you arrived at our site)

This information is transmitted to and stored by Google on servers in the United States. Google will use this information to evaluate your use of our website, compile reports on website activity, and provide other services relating to website activity and internet usage. For more information on how Google uses data, visit How Google uses data when you use our partners' sites or apps.

You can opt-out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

3. How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve our services
  • Communicate with you about the app and updates
  • Respond to your requests and support needs
  • Analyze usage patterns and improve user experience
  • Ensure security and prevent fraud
  • Comply with legal obligations and provide age-appropriate experiences where required
  • Show, organize, and refresh YouTube videos and related metadata in supported Sideline experiences

Age-related signals from Google Play are handled separately from general analytics and product personalization. We do not persist age ranges or age verification status unless required for legal compliance. If we store a supervised install ID, we retain and use it only as needed for revoked approval compliance.

We use YouTube API data only to provide user-facing YouTube-related features, maintain those features, troubleshoot errors, protect the service, and comply with applicable YouTube API Services requirements. We do not use YouTube API data to create unrelated user profiles or for advertising.

4. Information Sharing

We do not sell your personal information. We may share your information only in the following circumstances:

  • With your consent
  • With service providers who assist in our operations
  • To comply with legal obligations
  • To protect our rights and safety

When you view or interact with YouTube content, YouTube and Google may receive information as described in Google's and YouTube's terms and privacy policies. We do not sell YouTube API data or share authorized YouTube account data with third parties except as needed to operate Sideline, comply with law, or with your consent.

5. Data Retention, Deletion, and Revocation

We retain account information while your Sideline account is active. The account deletion process and optional retention period are described below.

If Sideline stores YouTube API data, we refresh or delete it in accordance with the YouTube API Services Developer Policies. Public, non-authorized YouTube API data is not stored for more than 30 days without being refreshed or deleted. Authorized YouTube API data is kept only while needed for the purpose you approved and for no longer than 30 days unless refreshed under an active authorization.

You can delete your account from the Account tab on your Sideline profile by following the steps on our account deletion page. By default, account deletion is scheduled and account data is retained for 30 days before permanent deletion. You may instead opt into immediate, unrecoverable deletion. If you cannot access the app, the account deletion page also explains how to contact support.

After deletion, the device remains registered as an anonymous Sideline installation. Its anonymous installation ID and push token are not linked to the deleted account. Targeted account notifications stop, but the device may continue to receive general broadcast notifications. Installation preferences such as theme and timezone remain on the device.

If you authorized Sideline to access Google or YouTube account data, you can revoke that access from your Google security settings at https://security.google.com/settings/security/permissions. After revocation, we will delete YouTube API data stored pursuant to that authorization as soon as possible and within the timeframes required by the YouTube API Services Developer Policies.

Deleting data from Sideline does not delete data stored by YouTube. To delete content or account data from YouTube itself, use YouTube's own applications, settings, or an authorized YouTube client that supports that action.

6. Data Security

We implement appropriate technical and organizational measures to protect your personal information. However, no method of transmission over the internet is 100% secure.

7. Your Rights

You have the right to:

  • Access your personal information
  • Correct inaccurate data
  • Request deletion of your data
  • Opt-out of certain data processing
  • Revoke Google or YouTube account authorization through Google security settings

8. Children's Privacy

Our service is not directed to individuals under the age of 13. We do not knowingly collect personal information from children under 13.

Where applicable law or platform rules require age-related compliance measures, we may process limited Google Play age-related signals on Android as described in this Privacy Policy.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last Updated" date.
