Privacy Policy
Last updated: March 10, 2026
1. Introduction
Welcome to Twin Pics (“we,” “our,” or “us”). Twin Pics is a daily AI image generation game where players craft prompts to create images that match a mystery challenge image as closely as possible. This Privacy Policy explains how we collect, use, store, and protect your information when you play.
2. Information We Collect
Account & Session Data
When you first play, we automatically create an anonymous account so we can track your game progress, scores, and leaderboard position. You can optionally sign in with Google or email to preserve your data across devices. If you sign in, we store your name, email address, and profile image.
Game Data
When you play, we store the text prompts you submit, the AI-generated images created from those prompts, and the similarity scores your images receive. This data powers the daily leaderboard and lets you see your past attempts.
Technical Data
Like most web applications, our hosting provider automatically collects basic request information such as IP addresses, browser type, and access timestamps. This data is used for security monitoring and is not linked to your game activity.
3. AI Services & Third-Party Processing
Twin Pics relies on third-party AI services to deliver the core game experience. When you submit a prompt, the following happens:
- 1Image Generation (Runware) -- Your text prompt is sent to Runware's AI image generation API to create your game image. Runware processes the prompt and returns the generated image. We do not send any personal data to Runware beyond the prompt text itself.
- 2Image Scoring (Google Gemini) -- Your generated image and the daily challenge image are sent to Google's Gemini AI to compute a visual similarity score (0--100). No personal data accompanies this request.
- 3Email Communications (Loops) -- If you create an account with an email address, your email, name, and subscription plan status are shared with Loops.so, our email marketing platform. Loops sends lifecycle emails such as welcome messages and account updates. You can unsubscribe from marketing emails at any time using the link in each email.
These services process data in accordance with their own privacy policies. We encourage you to review Runware's Privacy Policy and Google's Privacy Policy, and Loops' Privacy Policy for details.
4. Data Storage
Your data is stored across the following infrastructure:
Images
Generated images are stored on Vercel Blob, a secure cloud object storage service.
Game Records
Prompts, scores, and session data are stored in a Neon PostgreSQL database hosted in the cloud.
All data is transmitted over HTTPS and stored with industry-standard encryption at rest. We retain game data indefinitely to maintain leaderboard history, but you may request deletion at any time.
5. How We Use Your Information
- Provide the daily challenge game experience
- Generate and store AI images from your prompts
- Score your images against the daily challenge
- Display leaderboard rankings
- Maintain your game history across sessions and devices
- Send lifecycle email communications to registered users (e.g. welcome emails, account updates)

6. What We Don't Do
- ×We do not require an email address or social login to play -- anonymous accounts work automatically
- ×We do not sell or share your data with advertisers
- ×We do not use your prompts or images for AI model training
7. Cookies & Analytics
We use cookies for authentication and analytics:
- Session cookies maintain your login state (anonymous or signed in) and are required for the game to function
- We use Vercel Analytics and PostHog to understand how the game is used and to improve the experience
- Analytics data is aggregated and not linked to your personal identity
- Cookies do not track you across other websites
If you clear your cookies without first signing in with Google or email, your anonymous account and game history will no longer be accessible.
8. Your Rights
You have rights regarding your data:
- Request a copy of any data associated with your account
- Request deletion of your account, images, prompts, and scores
- Sign in to preserve your data, or clear your cookies to disassociate from an anonymous account
9. Children's Privacy
Twin Pics is designed for a general audience. The core game experience — generating images from prompts, viewing scores, and browsing the leaderboard — is available to everyone without creating an account or providing any personal information.
Account registration, which requires a name, email address, or Google sign-in, is intended for users aged 13 and older. We do not knowingly collect personal information from children under 13 through account registration. Anonymous sessions use only a session cookie necessary for game functionality and do not collect names, email addresses, or other identifying information.
If you are a parent or guardian and believe your child has created an account with personal information, please contact us and we will promptly delete the account and associated data.
10. Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date at the top of this page. We encourage you to review this policy periodically.
