Privacy,

Who this policy covers

Effective September 5, 2026. This policy applies to DojoStack, the DojoGo mobile app, our websites, and related services operated by DojoStack Labs LLC (collectively, the “Service”). A martial arts school may also have its own privacy practices for information it manages through the Service. When a school controls that information, direct school-specific requests to the school first.

Information we collect

Depending on how you use the Service, we may collect:

• Account and profile information, such as name, email address, profile photo, age or birth information, dojo affiliation, household relationships, rank, and membership details.
• Training and activity information, such as attendance, schedules, goals, progress, achievements, journal entries, and interactions with Sensei AI.
• Content and communications, including posts, comments, reactions, announcements, messages, photos, videos, support requests, and notification preferences.
• Transaction information, such as purchases, subscriptions, and order history. Payment card details are handled by payment providers and app-store platforms rather than stored directly by us.
• Device and usage information, including IP address, device and app identifiers, operating system, app version, approximate location inferred from IP address, logs, diagnostics, crash information, and interactions with the Service.

We receive information directly from you, from the dojo or family account that manages your profile, automatically from your device, and from service providers that help operate the Service.

How we use information

We use information to provide and personalize the Service; connect members with their dojo community; process memberships, purchases, and subscriptions; deliver announcements and notifications; support safety and account administration; respond to support requests; prevent fraud and abuse; troubleshoot and improve performance; comply with legal obligations; and, for eligible adult Free-tier users, support advertising.

Advertising and consent choices

DojoGo may display Google AdMob advertisements to eligible adult users on the Free tier. We do not display ads to child profiles, paid subscribers, or eligible dojo-sponsored users.

The Google Mobile Ads SDK may process device and advertising identifiers, IP address, app interactions, diagnostic information, and related technical data to deliver, limit, measure, secure, and report advertisements. DojoGo does not send your martial arts profile, training history, posts, messages, photos, videos, or precise location to Google as ad-request targeting data.

DojoGo currently requests non-personalized ads. Where personalized advertising is enabled in the future and legally permitted, it will be subject to the consent and opt-out choices available for your region. Eligible users can review available controls from Settings > Privacy choices. Learn more about how Google uses information from partner apps.

When information is disclosed

We disclose information only as reasonably necessary to operate the Service, including to:

• your dojo, authorized instructors or administrators, and household members according to account permissions;
• other users when you choose to publish or share community content;
• hosting, analytics, communications, support, payment, app-store, security, and advertising providers acting for us;
• law enforcement, regulators, or other parties when required by law or necessary to protect rights, safety, and the integrity of the Service; and
• a successor in connection with a merger, financing, acquisition, reorganization, or sale of assets, subject to appropriate safeguards.

Children and family profiles

Child profiles must be created or managed through an authorized parent, guardian, or dojo relationship. DojoGo does not serve advertising to child profiles. Parents and guardians may contact us or the associated dojo to request access to, correction of, or deletion of a child’s information, subject to applicable law and legitimate recordkeeping requirements.

Your privacy choices

You may update certain profile and notification settings in the Service, manage regional advertising choices through Settings > Privacy choices, or request access, correction, deletion, or a copy of information associated with your account. To delete a DojoGo account, use More > Settings > Delete account in the app or follow the instructions on our account deletion page. You may also have rights to restrict or object to certain processing and to appeal a denied request, depending on where you live.

We may need to verify your identity and authority before completing a request. Authorized agents may submit requests where permitted by law. We will not discriminate against you for exercising applicable privacy rights.

Retention, security, and transfers

We retain information for as long as reasonably necessary to provide the Service, maintain legitimate business and safety records, resolve disputes, enforce agreements, and meet legal obligations. Retention periods vary by the type of information and the reason it is used.

We use administrative, technical, and organizational safeguards designed to protect information. No storage or transmission method is completely secure. Information may be processed in the United States and other countries where we or our service providers operate, subject to protections required by applicable law.

Questions and requests

We may update this policy as the Service changes. Material updates will be identified by a revised effective date and, where required, additional notice.

For privacy questions or requests, contact support@dojostacklabs.com. Please include enough information for us to identify the relevant account and request without sending sensitive credentials or payment information.
