Fengcen Privacy Policy

Introduction

Fengcen ("we," "us," or "our") provides websites, software applications, online services, integrated AI features, account and billing features, and customer support under the Fengcen brand (collectively, the "Services"). Sliprail is one of Fengcen's products. This Privacy Policy explains how we collect, use, store, share, and protect information when you access or use the Services.

Some Fengcen features run locally on your device. Other features, especially account, subscription, cloud, sharing, online AI, and support-related features, require information to be processed on our servers or by third-party providers. Please read this Privacy Policy carefully before using the Services.

1. Information We Collect

1.1 Information You Provide Directly

We may collect information that you choose to provide, including:

• Account information, such as your email address, display name, and other information associated with your Fengcen account
• Subscription, order, transaction, invoice, refund, credit-related, and billing information, such as purchase records, subscription status, payment status, and usage records
• Communications you send to us, such as customer support requests, feedback, survey responses, business inquiries, or other messages
• Content you choose to submit through online features, such as AI prompts, uploaded files, images, screenshots, shared content, synced settings or content, and other materials you submit while using Sliprail or other Fengcen products with cloud features

1.2 Information We Collect Automatically

When you use the Services, we may automatically collect:

• Technical and device information, such as IP address, browser type, operating system, app version, device identifiers, crash information, and diagnostic logs
• Usage information, such as the features you use, access times, models selected, credit consumption, interaction frequency, sync status, and basic performance metrics
• Cookies, local storage, and similar technologies used for authentication, security, preference storage, analytics, and website functionality

1.3 Information We Do Not Automatically Collect

We do not automatically collect the contents of your local files, screenshots, clipboard items, camera or microphone data, or continuous keyboard input just because you install, access, or use a Fengcen product.

Such data is only transmitted when you actively choose a feature that requires it and intentionally submit, capture, sync, or share the relevant content, such as AI conversations, file analysis, screenshot workflows, cloud sync, shared links, or support submissions.

1.4 AI Features and Third-Party Providers

When you use AI or other online features in Fengcen Services:

• Your prompts, uploaded files, images, screenshots, conversation content, and related metadata may be transmitted to Fengcen servers and to third-party providers that help us process your request
• These providers may include AI model providers, hosting providers, search providers, payment providers, and tool providers you connect through supported integrations
• Fengcen does not use the specific content you submit to AI features to train Fengcen's own AI models
• Third-party providers process data according to their own terms and privacy policies, and their retention or usage practices may differ from ours
• Even where a feature is described as temporary, ephemeral, or non-persistent on our side, we cannot guarantee that a third-party provider will not retain records under its own policies

2. How We Use Your Information

We may use the information we collect to:

• Provide, maintain, authenticate, and secure the Services
• Enable local and cloud features, including accounts, syncing, sharing, AI, subscriptions, refunds, and billing
• Process purchases, manage subscriptions, handle credits, and maintain usage history
• Respond to support requests, feedback, business inquiries, and other communications
• Monitor reliability, diagnose problems, prevent abuse, and improve performance and user experience
• Develop, maintain, and improve existing or new features using feedback and aggregated, de-identified, or statistical usage information
• Comply with legal obligations, enforce our terms, and protect the rights, property, or safety of Fengcen, users, and others
• Send service-related notices, billing reminders, security alerts, updates, and other important communications
• Send marketing or promotional communications where you consent or where otherwise permitted by applicable law

3. How We Share Information

We do not sell your personal information. We may share information only in the following circumstances:

3.1 Service Providers and Infrastructure

We may share information with service providers that help us operate the Services, such as hosting, storage, analytics, payment, customer support, and security providers. These providers may access information only as reasonably necessary to perform services for us.

3.2 AI, Search, and Connected Tool Providers

If you use AI, web search, third-party integrations, sharing, syncing, or other connected features, the content and data required to fulfill your request may be sent to the relevant third-party providers that power those features.

3.3 Sharing Initiated by You

If you choose to create a shared link, publish content, collaborate, or otherwise disclose content through the Services, the information you choose to share may be accessible to other people who receive that content or link.

3.4 Legal, Safety, and Business Transfers

We may disclose information if we believe it is reasonably necessary to:

• Comply with law, regulation, legal process, or valid government requests
• Enforce our agreements and protect the security or integrity of the Services
• Detect, prevent, or address fraud, abuse, security issues, or illegal activity
• Protect the rights, property, or safety of Fengcen, our users, or the public
• Support a merger, acquisition, financing, reorganization, sale of assets, bankruptcy, or similar transaction

3.5 With Your Consent

We may share information for other purposes with your consent or at your direction.

4. Data Security, Storage, and Retention

We use commercially reasonable technical, administrative, and organizational measures to protect information. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

Some Service data may be stored on servers located in the United States or other jurisdictions involved in providing the Services. In addition, third-party providers you use through the Services may process data in the jurisdictions where they operate.

We retain information for as long as reasonably necessary to provide the Services, maintain accounts and subscriptions, process transactions, resolve disputes, enforce our agreements, comply with legal obligations, and support security, backup, and recovery needs.

Information that you keep only on your local device may remain only on that device unless you choose to upload, sync, share, or otherwise transmit it. If you delete content or close your account, some information may still remain in backups, logs, or records retained for technical, legal, accounting, fraud prevention, or compliance purposes for a limited period.

5. Your Rights and Choices

Depending on your jurisdiction and how you use the Services, you may have rights to:

• Access, review, or update certain account information
• Request deletion of your account or certain personal information
• Object to or restrict certain processing where required by law
• Withdraw consent where processing is based on consent
• Manage cookies or browser storage through your browser or device settings
• Manage shared content, synced content, marketing preferences, or conversation history where the relevant product feature provides those controls

If you are a resident of certain jurisdictions, you may have additional privacy rights under applicable law. We may need to verify your identity before fulfilling certain requests.

6. Children's Privacy

The Services are not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe that a child under 13 has provided personal information to us, please contact us so that we can take appropriate action.

7. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. If we make material changes, we may notify you through the Services, by email, or by other appropriate means. Your continued use of the Services after the updated Privacy Policy becomes effective means that the updated policy applies to your continued use of the Services.
