AI Caption Studio by AN Studios ("we", "our", "us") is committed to protecting your privacy. This policy explains how we collect, use, and safeguard your information when you use our mobile application.
When you create an account, we collect your email address, display name, and authentication credentials via Supabase Auth. Google Sign-In users share their Google profile information.
Images you upload for caption generation are processed temporarily in-memory, converted to base64, and sent to our AI providers (OpenRouter API) for analysis. Images are NOT stored on our servers.
Captions generated by AI are saved to your account in our Supabase database so you can access your history.
We collect basic usage analytics including caption generation counts, preferred styles, and language preferences to improve the service.
We may collect device type, operating system, and app version for debugging and compatibility purposes.
Your images are sent to OpenRouter AI vision models for analysis. The AI generates a text description of the image content.
Based on the image description, AI generates styled captions (funny, emotional, stylish, inspirational, romantic) in your chosen language (English, Bengali, or Hindi).
When you select a non-English language, captions are translated using AI translation models.
Your images and captions are NOT used to train AI models. They are processed in real-time and not retained by AI providers beyond the API request lifecycle.
Your account data and caption history are stored securely in Supabase (PostgreSQL) with row-level security (RLS) policies ensuring only you can access your data.
All data is encrypted in transit (TLS/SSL) and at rest. Authentication tokens are securely managed by Supabase Auth.
App preferences (notification settings, language) are stored locally on your device using SharedPreferences and Hive.
Images are processed in-memory only. They are never written to disk on our servers or stored in our database.
