Introduction
Captio ("we", "our", "the app") is a video subtitle generator developed by codeBage. This privacy policy explains how we collect, use, and protect your information.
Information We Collect
Data processed locally (on your device):
Videos you select from your device gallery
Audio extracted from videos for speech-to-text processing
Subtitle text generated by the Whisper AI model
Subtitle styling preferences and project data
This data stays on your device and is never uploaded to our servers.
Data sent to third-party services:
Google Gemini API: When you use the translation feature, subtitle text is sent to Google's Gemini API for translation. This data is processed according to Google's privacy policy.
Google AdMob: We display advertisements through Google AdMob, which may collect device identifiers, IP address, and usage data for ad personalization. You can opt out of personalized ads in your device settings.
Google Play In-App Review: We may prompt you to rate the app using Google Play's review API after multiple uses.
Data We Do NOT Collect
We do not create user accounts
We do not collect personal information (name, email, phone)
We do not upload your videos to any server
We do not store your data on any cloud server
We do not track your location
How Your Data Is Stored
All project data (videos, subtitles, preferences) is stored locally on your device using Android's app storage. When you uninstall the app, all data is automatically deleted.
Speech-to-Text Processing
Subtitle generation uses OpenAI's Whisper model running entirely on your device. Your audio is never sent to any server for transcription. The AI model is downloaded once and works offline.
Translation
When you translate subtitles, the subtitle text (not your video or audio) is sent to Google's Gemini API over an encrypted connection. Google's privacy policy applies to this data: https://policies.google.com/privacy
Advertising
We use Google AdMob to display ads. AdMob may collect:
Device advertising ID
IP address
General usage data

Children's Privacy
Captio is not directed at children under 13. We do not knowingly collect information from children.
