Privacy Policy

1. Information We Do NOT Collect

The Bluesky Alt Text Generator (including both the web application and browser extensions) is designed with privacy as the core principle. We explicitly do not collect, store, or retain:

• Your uploaded images or videos
• Generated alt text or captions
• Personal information or account details
• Usage analytics or tracking data
• IP addresses or device identifiers
• Browser history or browsing patterns
• Any form of personally identifiable information (PII)

2. How the Service Works

Web Application (alttext.symm.app)

When you use our web application:

• Your media files are processed temporarily in your browser and our server
• Files are sent to Google's Gemini AI service for analysis
• Generated alt text is returned to you immediately
• All data is automatically deleted from our servers after processing
• No logs or records of your usage are maintained

Browser Extensions (Chrome, Firefox)

Our browser extensions operate similarly but with additional privacy protections:

• Extensions only access content when you explicitly activate them
• No background data collection or monitoring occurs
• Image data is only processed when you click the extension button
• No cross-site tracking or data sharing

3. Third-Party Services

Google Gemini AI

We use Google's Gemini AI service to generate alt text and captions. Important details:

• We use a paid Google Gemini account, which means Google does not use your data for training their AI models
• Your images are sent to Google's servers for analysis but are not stored by Google
• Google's privacy policy for paid customers applies to this processing
• No user data is shared with Google beyond the immediate image analysis request

Railway Hosting

Our web application and server infrastructure are hosted on Railway:

• Railway provides secure, encrypted hosting services
• Standard server logs may be maintained by Railway for operational purposes
• No user content is permanently stored on Railway servers
• All processing is ephemeral and data is immediately discarded

4. Data Processing and Security

Your data security is paramount to us:

• All communications use HTTPS encryption
• Media files are processed in memory and never written to permanent storage
• Processing occurs in isolated, temporary environments
• No backups or copies of user content are created
• All temporary data is automatically purged after each request

5. Browser Extension Permissions

Our browser extensions request minimal permissions:

• Active Tab: To access images on the current page only when you activate the extension
• Host Permissions: To communicate with our API server for processing
• Storage: To save your preferences (theme, settings) locally on your device

We do not request permissions for browsing history, bookmarks, or background processing.

6. Local Data Storage

The only data stored locally includes:

• Theme preferences (light/dark mode)
• Extension settings and preferences
• No personal content or generated text is stored locally

7. International Data Transfers

Since we use Google Gemini AI and Railway hosting, your data may be processed in various countries where these services operate. However:

• Processing is always temporary and ephemeral
• No data is stored permanently in any jurisdiction
• All processing complies with applicable privacy regulations

8. Your Rights and Control

Since we don't store your data, there is no personal data to access, modify, or delete. You maintain complete control over:

• What content you choose to process
• When you use the service
• Your local browser settings and preferences

9. Children's Privacy

Our service does not knowingly collect any information from children under 13. The service is designed to be safe for all users, with no data collection regardless of age.

10. Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated "Last Updated" date. Since we don't collect contact information, we recommend checking this page periodically for updates.

11. Open Source Transparency

Our service is completely open source and available on GitHub. You can review our code to verify our privacy practices and data handling procedures at any time.
