Privacy Policy

Last updated: March 2026

1. Introduction

ComicInk ("we", "us", or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our website, mobile applications (including our iOS app), and related services. Please read this policy carefully. By using ComicInk on any platform, you consent to the practices described in this Privacy Policy.

2. Information We Collect

Information You Provide

  • Account Information: When you create an account, we collect your name, email address, and password. If you sign in with Apple, we receive the information you choose to share (name and email address, which may be a private relay address if you choose to hide your email).
  • Payment Information: On the web, our payment processor (Stripe) collects payment card details. In our iOS app, purchases are processed by Apple through the App Store — we receive transaction confirmation and product identifiers but do not receive or store your payment card details. We do not store your full credit card number on any platform.
  • Content You Create: We store the comics, characters, stories, prompts, and other content you create using our Service.
  • Communications: If you contact us, we collect the information you provide in your messages.

Information Collected Automatically

  • Usage Data: We collect information about how you use our Service, including pages visited, features used, and actions taken.
  • Device Information: We collect information about the device you use to access our Service, including device type, operating system, browser type, and on mobile devices, device model and OS version.
  • Log Data: Our servers automatically record information including your IP address, access times, and referring URLs.
  • Cookies and Local Storage: On the web, we use cookies and similar technologies to maintain your session and remember your preferences. On mobile, we use secure on-device storage for authentication tokens and preferences.

3. How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve our Service
  • Process transactions and send related information

  • Monitor and analyze usage patterns and trends
  • Detect, investigate, and prevent fraudulent or unauthorized activity
  • Personalize and improve your experience

4. AI Processing and Your Content

ComicInk uses artificial intelligence to generate images based on your prompts and content. Here's how your data is handled in this process:

  • Prompt Processing: Your text prompts are sent to AI service providers to generate images. These providers may temporarily process your prompts but do not retain them for training purposes under our agreements.
  • Generated Images: AI-generated images are stored on our servers and associated with your account.
  • Character and Story Data: Information about your characters, worlds, and stories is used to generate consistent content and may be included in prompts sent to AI services.
  • No Training on Your Content: We do not use your content to train our own AI models, and our agreements with AI providers prohibit them from using your content for training.

5. How We Share Your Information

We may share your information in the following circumstances:

  • Service Providers: We share data with third-party vendors who help us operate our Service, including:
    • Supabase (database and authentication)
    • Stripe (web payment processing)
    • Apple (App Store in-app purchase processing)
    • AI image generation providers
    • Cloud hosting providers (Vercel)
    • PostHog (analytics — with your consent on web; used on mobile for product analytics)
    • Google Analytics and Google Ads (web usage analytics and advertising — with your consent)
    • Sentry (error tracking and application monitoring on web and mobile)
  • Published Content: If you choose to publish your comics, they become publicly accessible.
  • Collaborators: If you invite collaborators to your comics, they can access the shared content.
  • Legal Requirements: We may disclose information if required by law or in response to valid legal requests.
  • Business Transfers: If we are involved in a merger, acquisition, or sale of assets, your information may be transferred.

6. Data Security

We implement appropriate technical and organizational measures to protect your information, including:

  • Encryption of data in transit using TLS/SSL
  • Encryption of sensitive data at rest
  • Regular security assessments and updates
  • Access controls limiting who can access your data
  • Secure authentication mechanisms

However, no method of transmission over the Internet or electronic storage is 100% secure. While we strive to protect your information, we cannot guarantee absolute security.

7. Data Retention

We retain your information for as long as your account is active or as needed to provide you services. We will retain and use your information as necessary to comply with legal obligations, resolve disputes, and enforce our agreements. If you delete your account, we will delete or anonymize your personal information within 30 days, except where we are required to retain it for legal purposes.

8. Your Rights and Choices

Depending on your location, you may have certain rights regarding your personal information:

  • Access: You can request a copy of the personal information we hold about you.
  • Correction: You can request that we correct inaccurate or incomplete information.
  • Deletion: You can request that we delete your personal information.
  • Data Portability: You can request a copy of your data in a portable format.

9. Cookies, Tracking Technologies, and Mobile Analytics

We use cookies and similar tracking technologies across our platforms for different purposes. We categorize these into two groups:

Necessary (Always Active)

  • Keep you signed in to your account (cookies on web, secure on-device storage on mobile)
  • Remember your preferences and settings
  • Sentry: We use Sentry on both web and mobile to monitor application errors and crashes. This helps us identify and fix bugs quickly. Sentry collects error data, stack traces, and basic device information. It does not track your browsing behavior or build a profile of you. This is always active as it is essential for maintaining service reliability.

Analytics

On the Web (Requires Your Consent)

The following services are only activated after you accept analytics cookies via our consent banner:

  • PostHog: We use PostHog for product analytics and session recording. PostHog tracks page views, feature usage, and may record your browsing session (with all form inputs masked) to help us understand how users interact with ComicInk and improve the experience. PostHog data is hosted in the United States.
  • Google Analytics & Google Ads: We use Google Analytics to understand website traffic and usage patterns, and Google Ads to measure advertising effectiveness. Google may use this data in accordance with its own privacy policy.
  • Sentry Session Replay: When you consent to analytics, Sentry may also record session replays when errors occur, helping us reproduce and fix bugs. All form inputs are masked in these recordings.

On Mobile

  • PostHog: We use PostHog in our mobile app to collect product analytics such as feature usage and user actions. This helps us understand how users interact with the app and improve the experience. PostHog on mobile does not record sessions or screen recordings.
  • Sentry: We use Sentry in our mobile app to capture crash reports and error data, helping us maintain app stability.
  • No Ad Tracking: Our mobile app does not use advertising identifiers (IDFA) and does not track you across other apps or websites.

Your Choices

On the web: When you first visit ComicInk, you will see a consent banner asking you to accept or decline analytics cookies. You can change your preference at any time by clearing your browser's local storage for our site and revisiting, which will display the consent banner again. You can also control cookies through your browser settings. Declining analytics cookies does not affect your ability to use ComicInk.

On mobile: You can limit data collection by adjusting your device privacy settings. On iOS, you can disable analytics sharing in Settings > Privacy & Security > Analytics & Improvements. Uninstalling the app will stop all data collection.

10. Children's Privacy

Our Service is not intended for users under 18 years of age. We do not knowingly collect personal information from children under 18. If we learn that we have collected personal information from a child under 18, we will take steps to delete that information promptly. If you believe we have collected information from a child under 18, please contact us immediately.

11. International Data Transfers

Your information may be transferred to and processed in countries other than your country of residence. These countries may have data protection laws that are different from the laws of your country. By using our Service, you consent to the transfer of your information to the United States and other countries where we and our service providers operate.

12. California Privacy Rights

If you are a California resident, you have additional rights under the California Consumer Privacy Act (CCPA):

  • The right to know what personal information we collect, use, and disclose
  • The right to request deletion of your personal information
  • The right to opt-out of the sale of your personal information (we do not sell personal information)
  • The right to non-discrimination for exercising your privacy rights

13. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
