2. Collecting and Using Your Personal Data

Types of Data Collected

Data from TikTok OAuth

When you authorize via TikTok OAuth, we access only the following information from your TikTok profile, as explicitly permitted by TikTok's authorization screen:

1. Open ID (a unique identifier for your TikTok account)
2. Display name (your TikTok username)
3. Avatar URL (your profile picture)
4. Video content you choose to generate and publish through our Service
5. Usage Data

We do not collect email addresses, phone numbers, physical addresses, or any other personal information beyond what TikTok provides through its OAuth scope.

We do not store passwords. All authentication is handled by TikTok's OAuth system.

Usage Data

Usage Data is collected automatically when you interact with the Service. This may include your IP address, browser type and version, pages visited, time and date of visits, time spent on pages, and basic diagnostic information needed to operate the platform.

Information from Third-Party Social Media Services

You can authorize the Service through TikTok OAuth. We only request the permissions necessary to generate and publish videos on your behalf:

1. TikTok (via OAuth 2.0)

When you grant access via TikTok OAuth, we receive only the public profile information you have authorized (open_id, display_name, avatar). We do not access your private messages, following list, or any data beyond the OAuth scope you approve.

Our API client also uses the YouTube API Service for certain video processing features. If you use the YouTube API Service, we recommend reviewing Google's Privacy Policy. You can review or revoke access permissions in your Google Account at any time.

Siweite's use of information received from Google APIs and its transfer to any other application will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

We do not share your data with third-party AI tools, and we comply with every social media platform's data rules.

3. Cookies

We use only essential cookies that are necessary for the technical operation of the Service. We do not use tracking cookies, advertising cookies, or third-party analytics cookies. Specifically:

1. Session Cookies. These are temporary cookies that expire when you close your browser. We use a single session cookie to maintain your OAuth authorization state while you are actively using the platform.
2. No Tracking or Persistent Cookies. We do not deploy web beacons, pixel tags, or any other tracking technologies. We do not track your browsing behavior across other websites.

Because tkshark does not create system accounts, we do not use cookies for authentication, login persistence, or user preference storage. The session cookie is deleted automatically when you close your browser. You can configure your browser to block cookies, but this may prevent the OAuth flow from functioning correctly.

4. Use of Your Data

The Company may use the data we access through TikTok OAuth for the following limited purposes:

1. To generate AI-powered short videos based on the text you provide.
2. To publish videos to your TikTok account when you explicitly request it.
3. To display your TikTok profile information (name and avatar) within the Service for identification purposes.
4. To improve and maintain the quality of our video generation Service.
5. To respond to your support inquiries or requests.
6. For business transfers — in the event of a merger, acquisition, or sale of assets, your data may be transferred as part of that transaction.
7. To comply with legal obligations and enforce our policies.

We do not use your data for marketing, advertising, or profiling purposes. We do not sell your personal information.

5. Retention of Your Data

We retain the minimal data accessed via TikTok OAuth only as long as necessary to provide the Service. Video generation data is retained temporarily during processing and may be cached for performance. You can revoke tkshark's access to your TikTok account at any time through your TikTok settings, after which we will no longer be able to access your profile information.

6. Transfer of Data

Your information is processed at the Company's operating offices and through cloud infrastructure providers we engage. By using the Service, you consent to this transfer. We ensure that any third-party processors adhere to data protection standards consistent with this policy.

7. Your Rights

Since tkshark does not maintain a system account for you, there is no stored profile to delete. However, you may revoke tkshark's OAuth access at any time via your TikTok account settings. If you have questions about data we may hold, you can contact us and we will address your request promptly.

8. Disclosure of Data

We do not sell, trade, or share your personal data with third parties except as necessary to provide the Service (e.g., cloud processing) or as required by law. If the Company is involved in a merger, acquisition, or asset sale, your data may be transferred. We may also disclose data in response to valid legal requests from public authorities.

9. Security

We take reasonable technical and organizational measures to protect any data processed through the Service. All communications are encrypted via HTTPS. OAuth tokens are stored securely and never exposed. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

10. Children's Privacy

Our Service is not directed at anyone under the age of 13. We do not knowingly collect information from children under 13. TikTok's own terms require users to be at least 13 years old, and we rely on TikTok's age verification.

11. Links to Other Websites

Our Service may contain links to websites not operated by us, including TikTok, YouTube, and other third-party platforms. We have no control over and assume no responsibility for the content, privacy policies, or practices of those sites.

12. Changes to This Privacy Policy

We may update this Privacy Policy periodically to reflect changes in our practices or legal requirements. We will notify you of material changes by posting the updated policy on this page with a revised effective date.
