プライバシーポリシー

1. Introduction

JerkMotion ("we", "us", "our") operates jerkmotion.com and related domains (the "Service"). This Privacy Policy explains what information we collect when you use the Service, how we use it, and the choices you have. By using the Service, you agree to the practices described here.

2. Age Requirement

The Service is restricted to adults. You must be at least 18 years old, or the age of majority in your jurisdiction if higher, to access or use the Service. We do not knowingly collect personal information from anyone under this age.

3. Information We Collect

Account information. If you create an account, we collect a username, email address, and a hashed password. We never store your password in plain text.

Contact form submissions. If you contact us (including DMCA takedown requests), we collect the name, email address, and message you provide.

Usage and technical data. We automatically collect data such as your approximate country (derived from your connection; we do not store raw IP addresses long-term), browser/device information, pages viewed, and viewing activity (e.g. which videos were watched, for view-count and recommendation purposes).

Cookies and local storage. We use cookies and browser local storage to run the Service. See Section 5 below.

4. How We Use Information

• To provide, operate, and maintain the Service (accounts, favorites, watch later, history, downloads).
• To remember your preferences (language, theme, age verification).
• To respond to contact and DMCA requests.
• To detect and prevent abuse, fraud, and rate-limit automated requests.
• To measure and improve Service performance through analytics.
• To serve and measure advertising, including through third-party ad networks.

5. Cookies & Local Storage

We use the following categories of cookies and browser local storage:

• Strictly necessary — session/auth token, language preference, age-verification flag, layout preferences.
• Functional — theme preference, recent searches, "new content" indicators.
• Advertising — cookies used to help deliver and measure ads, including some set directly by our advertising partners (see Section 6).
• Analytics — cookies/identifiers used by our analytics services (see Section 7).

You can control or delete cookies through your browser settings. Blocking certain cookies may affect Service functionality (e.g. staying logged in).

6. Advertising Partners

We display advertising to keep the Service free. We work with a number of third-party advertising networks. When these networks serve an ad, they may set their own cookies or use similar technologies to measure ad performance and, depending on your settings and location, personalize ads. We do not control these networks' data practices directly. A list of our current advertising partners is available on request via our Contact page.

7. Analytics

We use one or more analytics services to understand aggregate traffic and usage patterns. Analytics data is used in aggregate and is not used to make decisions about individual users.

8. Data Retention

We retain account data for as long as your account is active. Contact form submissions are retained as long as necessary to handle the request and for record-keeping (e.g. DMCA compliance history). Usage/analytics data is generally retained in aggregate or anonymized form after a limited period.

9. Data Sharing

We do not sell your personal information. We share data with third parties only: (a) with advertising and analytics providers as described above, (b) with service providers who help us operate the Service (e.g. hosting and infrastructure, security and anti-abuse providers), (c) if required by law or to respond to valid legal process, or (d) to protect the rights, safety, or property of JerkMotion, our users, or the public.

10. Your Rights

Depending on where you live, you may have rights to access, correct, delete, or export your personal data, and to object to or restrict certain processing (for example under the GDPR in the EU/EEA, or the CCPA in California). To exercise these rights, contact us using the form on our Contact page. You can delete your account and associated personal data at any time from your account settings, or by contacting us.

11. Content Hosting

Some video and image content is hosted on our own infrastructure; other content is embedded or mirrored from third-party partner sites. This section concerns content, not personal data — see our Terms of Service for details, and our Contact page for our DMCA policy.

12. Security

We use reasonable technical and organizational measures to protect your information, including access controls on protected content and safeguards against abusive or automated access. No method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

13. International Users

The Service is accessible globally and available in multiple languages. Your information may be processed on servers located outside your own country. By using the Service, you consent to this transfer and processing.

14. Changes to This Policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last updated" date above. Continued use of the Service after changes take effect constitutes acceptance of the revised policy.
