2.1 Account Information
When you create an account, we collect information provided by your OAuth provider (Google or Apple), which may include your email address and display name.
2.2 Chat and Content Data
We store messages you send and receive within the Service, characters you create (including names, descriptions, personality traits, and images), and related metadata. This data is necessary to provide and improve the Service.
2.3 Payment Information
Payment processing is handled by Stripe. We do not store your credit card numbers or full payment details. We receive transaction identifiers and subscription status from Stripe to manage your account. Please refer to Stripe's Privacy Policy for details on how Stripe handles your payment data.
2.4 Usage and Device Data
We automatically collect certain technical information when you use the Service, including IP address, browser type, device type, operating system, referring URLs, pages visited, and interaction timestamps. We use analytics services (such as Firebase Analytics) to understand usage patterns.
2.5 Images
Images you upload (such as character reference images) and AI-generated images are stored on our cloud infrastructure (AWS S3). These images are associated with your account.
3. How We Use Your Information
We use your personal data for the following purposes:
- Provide the Service: To operate the platform, deliver chat functionality, generate AI responses, and manage your account.
- Improve the Service: To analyze usage patterns, fix bugs, and develop new features.
- AI Training: We may use de-identified and aggregated chat data to train and improve our AI models. We take reasonable measures to strip personally identifiable information before using data for this purpose.
- Safety and Moderation: To detect, prevent, and respond to violations of our Terms of Service, including prohibited content.
- Payments: To process subscriptions, credits, and related billing.
- Communication: To send you service-related notifications (e.g., account verification, security alerts, billing updates). We do not send marketing emails without your explicit consent.
4. Legal Basis for Processing (EEA/UK Users)
If you are located in the European Economic Area (EEA) or the United Kingdom, we process your personal data based on the following legal grounds:
- Contract: Processing necessary to provide you with the Service you requested (Art. 6(1)(b) GDPR).
- Legitimate Interest: Processing necessary for our legitimate interests, such as improving the Service, ensuring security, and preventing abuse (Art. 6(1)(f) GDPR).
- Consent: Where required, we will obtain your consent before processing (Art. 6(1)(a) GDPR).
- Legal Obligation: Processing necessary to comply with applicable laws (Art. 6(1)(c) GDPR).
5. Data Sharing
We do not sell your personal data. We may share your information with:
- Service Providers: Third-party vendors who assist us in operating the Service, including cloud hosting (AWS), payment processing (Stripe), email delivery (AWS SES), and analytics (Firebase). These providers process data on our behalf under contractual obligations.
- AI Model Providers: To generate text and image responses, we send relevant chat context to third-party AI inference providers. This data is transmitted for inference purposes only.
- Legal Requirements: We may disclose information if required by law, regulation, legal process, or governmental request.
- Business Transfers: In the event of a merger, acquisition, or sale of assets, your data may be transferred as part of that transaction.
6. Data Retention
We retain your data for as long as your account is active or as needed to provide the Service. When you delete your account, we will delete or anonymize your personal data within 30 days, except where retention is required by law or for legitimate business purposes (e.g., fraud prevention, legal obligations). Publicly created characters may remain visible after account deletion in anonymized form.
7. Data Security
We implement reasonable technical and organizational measures to protect your data against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the internet or electronic storage is completely secure, and we cannot guarantee absolute security.
