01 Introduction

This Privacy Policy applies to the SubmitKit application (referred to as "Application") for mobile devices, created and operated by SubmitKit / JayCo GK (referred to as "Service Provider"). The Application is provided as a freemium service and is intended for use "AS IS".

This policy describes what information we collect, why we collect it, how it is used, and the choices you have. By downloading or using the Application, you agree to the practices described here.

02 Data Controller

Account Information

Content You Import

When you import technique videos into the Application, we process and store:

Subscription & Payment Information

SubmitKit uses RevenueCat to manage in-app subscriptions. We do not collect or store your payment card details. RevenueCat processes subscription status, App Store transaction identifiers, and device identifiers used to restore purchases. See RevenueCat's privacy policy linked in Section 6.

04 How We Use Your Information

The Service Provider uses the information collected to:

05 AI-Powered Auto-Tagging

SubmitKit uses the Claude API, provided by Anthropic, PBC, to automatically classify technique videos when you import them. This is a core feature of the Application.

What is sent to Anthropic: When you import a video, the video URL and any available metadata (such as title or description) are sent to Anthropic's servers. Anthropic returns structured tag classifications (technique type, position, Gi/No-Gi, difficulty). Your name, email address, and other personally identifiable information are not included in these requests.

Anthropic's use of data submitted via their API is governed by their own API usage policy and privacy notice. All AI processing is performed in accordance with this Privacy Policy and applicable laws.

Your API credentials are stored exclusively on our secure backend servers and are never embedded in the Application binary distributed to your device.

06 Third-Party Access

Only aggregated, anonymised data is periodically transmitted to external services to aid the Service Provider in improving the Application. The Service Provider may share your information with third parties as described in this policy.

The Application integrates with the following third-party services, each of which has its own Privacy Policy:
