Keep Tossing Lab., Inc.
Effective date: September 10, 2026

Keep Tossing Lab., Inc. ("KTL," "we," "us," or "our") operates b4. This Privacy Policy explains how we collect, use, disclose, and protect personal information when you use the b4 application (the "App"), our website at b4-app.com, and related features and services (collectively, the "Services").

Our Terms of Use / End User License Agreement govern use of the Services. Accepting those terms or using the Services does not replace any separate consent required for a particular use of personal information.

1. Information we collect

Account and profile information. We collect information you provide when creating or managing an account, such as your name, username, email address, login credentials, and profile information.

Videos and sharing information. When you choose to upload a video for sharing, we collect the selected video and the information you include with it, such as a caption or baseball performance results. A video may include people's images, voices, and other identifying details. We also process the sharing choices you make, including your decision to publish a public share page. This does not mean that every video recorded on your device is automatically uploaded.

Other information you provide. We collect information you send in support requests, feedback, consent records, or other communications, and information you choose to submit through available account or baseball-performance features.

Technical and usage information. When you use the Services, technical information may be collected, including IP addresses, device and browser information, app version, access times, and interactions with the Services. The App also uses Adjust as described in Section 4. Technical identifiers and usage records may constitute personal information; we do not assume that they are anonymous simply because they do not include your name.

2. How we use information

We use personal information to:

Create and manage accounts and provide the features you request.
Host and deliver videos and related information that you choose to share.
Publish and operate public share pages at your direction.
Provide support, respond to requests, and communicate service or policy updates.
Maintain the reliability and security of the Services and investigate misuse.
Measure app activity and advertising performance through Adjust, subject to applicable permissions.
Record and respect sharing choices, permissions, and withdrawal or deletion requests.
Comply with legal obligations and protect lawful rights.

We process uploaded videos to provide the sharing you request. We do not treat your decision to share a video as permission for KTL to use it in promotional materials. Any such use requires the separate permission described in Section 3.

Where applicable law requires a legal basis for processing, we rely on the basis appropriate to the activity, such as providing a service you request under our agreement, complying with legal obligations, or our legitimate interests in security and service administration where those interests are not overridden by your rights. We obtain consent where required and allow it to be withdrawn.

3. Sharing choices and public pages

Sharing at your direction. You may choose the recipients, platforms, or other destinations to which you share your videos and results. You are responsible for having the rights and permissions needed for the audience and destination you select.

Public share pages. If you choose to publish a public share page, the video and information you include on that page become publicly accessible. Other people may view the page, forward its link, or save and redistribute its content. Do not publish information you do not want others to access. A public page should not be treated as private merely because you initially send its link to a particular person.

Sharing with a coach, team member, or other selected person does not by itself make content public. However, if you send that person a link to a public page, the underlying page remains public.

People appearing in videos. Before uploading or sharing another person's footage or information, you must obtain any required permission for that activity and audience. For minors, this includes parental or guardian consent where required. Private coaching permission does not automatically include permission for public posting or promotional use.

Optional promotional use. If KTL wishes to use a reel in its own promotional materials, we will request separate, optional permission identifying the reel and intended uses and channels, as described in the Terms of Use. You may decline without losing ordinary sharing access and may withdraw that permission by contacting us.

Deleting shared content. We will promptly remove public access to content covered by a deletion request and complete deletion as described in Section 7. We cannot guarantee deletion of copies independently saved or reposted by other people or services outside our control. We will take any further steps required by applicable law concerning recipients or public copies.

4. Adjust and app advertising measurement

We use Adjust in the App to help measure app installations, app activity, and advertising performance. This Adjust integration applies to the App, not our website.

Depending on device permissions and the enabled features, Adjust may process device and app information, IP addresses, installation and session information, app interaction events, and identifiers permitted by your device settings and applicable law. This information helps attribute app activity to advertising campaigns. Where enabled, relevant measurement information may be exchanged with advertising partners, subject to applicable consent and sharing controls.

Where this activity constitutes tracking under Apple's rules, we request permission through Apple's App Tracking Transparency framework before tracking. We respect your choice if you decline. You can manage the App's tracking permission in your device settings. Declining tracking does not prevent ordinary use of the App.

Sharing a video does not authorize us to provide its contents to Adjust or advertising partners. Our video-sharing permission is separate from advertising and tracking permissions.

For further information, see Adjust's Privacy Policy. We remain responsible for the way Adjust is configured and used in our App and for coordinating applicable privacy requests with it.

5. Website cookies and communications

Our website may use cookies and similar technologies to support its operation and remember preferences. You can manage cookies through your browser, although disabling them may affect some website features. We obtain consent for non-essential cookies where required. Deleting a browser cookie does not necessarily erase information already held by a service provider.

We may send service messages about your account, support requests, or changes affecting the Services. Where permitted and with consent where required, we may also send marketing communications. You can opt out of marketing emails through an available unsubscribe option or by contacting us. Necessary service messages are separate from marketing communications.

6. When we disclose information

We disclose personal information in the following circumstances:

Your sharing instructions: to recipients and platforms you select, or publicly when you choose to publish a public share page.
Service providers: to providers performing functions for us, such as hosting, storage, communications, and technical support, subject to appropriate contractual restrictions and safeguards.
Adjust and advertising measurement partners: as described in Section 4 and subject to applicable permissions.
Affiliates: where necessary to help provide or support the Services, subject to appropriate restrictions and this Policy.
Business transactions: in connection with a merger, acquisition, restructuring, or asset transfer, subject to applicable privacy requirements and appropriate safeguards.
Legal and security matters: where necessary to comply with law, respond to lawful requests, enforce our terms, prevent fraud, or protect rights and safety.
Separate permission: for another purpose where we have explained the proposed disclosure and obtained any required consent.

Third-party websites, social platforms, and services you independently choose may handle information under their own privacy policies. Their practices are outside the scope of this Policy.

7. Retention and deletion

We retain personal information only for as long as needed for the purposes described in this Policy, taking into account the features you use, your sharing choices, and applicable legal obligations.

Account and content deletion. You may initiate account deletion through the App. You may also request deletion of specific uploaded content through available controls or by contacting us. We may take proportionate steps to verify your identity or authority before acting on a request.

We will promptly remove public access to the content covered by your request. We will permanently delete the relevant account information and uploaded content without undue delay and no later than 30 days after receiving your request, or sooner where applicable law requires. During processing, we will not continue publishing or otherwise using the content except as necessary to complete deletion or comply with law. We will confirm completion of an account-deletion request.

No retained backup copies. We do not retain backup copies of deleted account information or uploaded content after deletion is completed. The 30-day period includes deletion of any such copies held by us or by service providers acting on our behalf. We coordinate applicable deletion requests with our service providers, including Adjust for relevant app-measurement records.

Legally required records. If law requires us to retain a particular record, we retain only what is required for that purpose and period, restrict its use, and explain the exception where permitted. This is not a general right to retain deleted videos or backup copies.

Deleting your b4 account does not necessarily cancel an App Store subscription. Manage any subscription separately through your Apple Account settings.

8. Children and adult-managed sharing

Individuals must be at least 13 years old to register for or independently access the Services, subject to any additional age or parental-agreement requirements in the Terms of Use. We do not knowingly permit accounts for children under 13 or knowingly collect personal information directly from them.

Parents, guardians, and authorized adult coaches may upload footage of a minor only with the permissions required for the intended uses. Required parental or guardian consent must cover the upload and intended sharing audience, including public access where selected. The adult providing the footage must have authority to do so and maintain evidence of the required permission. Any optional promotional use requires the applicable separate permission.

If you believe information about a child has been collected or shared without the required permission, contact us. We will investigate and take appropriate steps, including removing public access and deleting information where required. An adult may not use these provisions to bypass the minimum account age or other requirements applicable to children's information.

9. Your choices and privacy rights

You may use available account controls to review or update information, choose how to share content, manage permissions, or initiate account deletion. You may also contact us about information that cannot be corrected through the interface, including calculated or uploaded records.

Depending on where you live and the laws that apply, you may have rights to access, correct, delete, or obtain a copy of personal information; restrict or object to processing; withdraw consent; or opt out of certain advertising-related uses or disclosures. You may also have a right to complain to a privacy regulator. We handle these requests within applicable deadlines and do not deny rights merely because a particular control is unavailable in the App.

Where processing relies on consent, you may withdraw that consent. Withdrawal does not invalidate processing lawfully carried out before withdrawal. Withdrawing permission necessary for a particular sharing feature may mean that we can no longer provide that feature for the affected content.

10. Security and international processing

We use reasonable technical and organizational measures to protect personal information. No system is completely secure. You should protect your account credentials and contact us if you suspect unauthorized access.

KTL is based in Taiwan. Information may be processed in other countries where our affiliates or service providers operate. Where applicable law requires safeguards for international transfers, we apply the required safeguards. You may contact us for information about the processing or safeguards relevant to your personal information.

11. Changes to this Policy

We may update this Policy to reflect changes in the Services or applicable requirements. We will update the effective date and provide notice of material changes through the App, website, or other appropriate means. Where additional consent is required for a change in processing, we will obtain it before making that change. Continued use alone does not replace legally required consent.
