Privacy Policy

1. Introduction

Stacdin ("we", "our", or "us") operates stacdin.com and provides an AI-powered LinkedIn content creation and scheduling platform. This Privacy Policy explains how we collect, use, store, and protect your information when you use our service.

By using Stacdin, you agree to the practices described in this policy. If you do not agree, please do not use our service.

2. Information We Collect

2.1 Account Information

When you register, we collect your name, email address, and a password (stored as a secure hash).

2.2 LinkedIn Data (via OAuth)

When you connect your LinkedIn account, we receive and store:

• Your LinkedIn profile ID, name, and profile picture
• An access token to publish posts on your behalf
• Posts you choose to import for AI voice training

We access LinkedIn only with the permissions you explicitly grant during OAuth authorization. We do not access your LinkedIn connections, messages, or any data beyond what is needed to operate the service.

2.3 Content You Create

We store the posts, drafts, templates, and writing samples you create or import within Stacdin. This content is used to power your AI voice profile.

2.4 Usage Data

We collect standard usage logs including pages visited, features used, and error reports to improve our service.

2.5 Payment Information

Payments are processed by a third-party payment provider. We do not store your full credit card details on our servers.

3. How We Use Your Information

• To provide and operate the Stacdin platform
• To train your personal AI voice profile based on your writing samples and published posts
• To schedule and publish posts to LinkedIn on your behalf
• To send you product updates, notifications, and support communications
• To improve our AI models and product features
• To detect and prevent fraud or abuse
• To comply with legal obligations

AI Training: Your writing samples and posts are used to build your personal AI voice profile. This data is used solely to personalize the AI for your account. We do not use your content to train shared or generic AI models accessible to other users.

4. LinkedIn API Compliance

Our use of LinkedIn data is governed by the LinkedIn API Terms of Use. Specifically:

• We only access LinkedIn data for the purpose of providing you our service
• We do not sell or share your LinkedIn data with third parties for advertising
• You can revoke LinkedIn access at any time via your LinkedIn account settings
• We store LinkedIn access tokens securely and do not expose them to unauthorized parties

5. Data Sharing

We do not sell your personal data. We may share data with:

• Service providers: Hosting, database, and payment processors who operate under confidentiality agreements
• AI providers: We may use third-party AI APIs (e.g., OpenAI) to generate content. Prompts sent to these services may include your writing style information but not your personal identifying details
• Legal requirements: If required by law, court order, or to protect our rights

6. Data Retention

We retain your data for as long as your account is active. If you delete your account, we will delete your personal data within 30 days, except where retention is required by law or for legitimate business purposes (e.g., billing records).

You may request deletion of your AI voice profile and writing samples at any time without closing your account by contacting us at support@stacdin.com.

7. Your Rights

Depending on your location, you may have the right to:

• Access the personal data we hold about you
• Correct inaccurate data
• Request deletion of your data
• Export your data in a portable format
• Withdraw consent for data processing
• Lodge a complaint with a supervisory authority (EU/UK users)

To exercise these rights, contact us at support@stacdin.com.

8. Security

We implement industry-standard security measures including encrypted connections (HTTPS), hashed passwords, and access-controlled infrastructure. However, no system is completely secure. We encourage you to use a strong, unique password for your Stacdin account.

9. Cookies

We use essential cookies required to keep you logged in and maintain your session. We do not use tracking or advertising cookies.
