Opt-Out of Personalized Advertising

You have control over personalized advertising:

1. In-App Setting: You can disable personalized ads directly in the app by going to Settings → Legal & Privacy → Personalized Ads. When disabled, you will still see ads, but they will not be personalized based on your interests.

2. Device Settings: You can also limit ad tracking using your device settings:

   • Android: Settings → Google → Ads → Opt out of Ads Personalization

Note: Opting out of personalized ads does not stop ads from being displayed, but it may make them less relevant to your interests.

Ad-Free Version

You can upgrade to the premium version of Stash2Go to remove all advertisements, including Google AdMob and Unity Ads. The premium version provides an ad-free experience and additional features. When you upgrade, all advertising-related data collection by Google AdMob and Unity Ads will cease, as these services are completely removed from the premium version of the app.

To enable synchronization of your app preferences across multiple devices, Stash2Go stores certain preference data on our servers. This includes:

• Unit preferences (metric/imperial, weight units, length units)
• Color theme preferences
• Appearance settings
• Other app configuration settings

Purpose: This data is stored solely to enable cross-device synchronization and to restore your preferences if you reinstall the app or use the app on a new device.

Data Storage: Preferences are stored securely on our servers and are associated with your Ravelry username. The data is encrypted in transit and stored in a secure database.

Your Rights:

• You can export your preferences at any time via Settings → Legal & Privacy → Export Preferences (sends preferences as JSON via email)
• You can delete all server-stored preferences at any time via Settings → Legal & Privacy → Delete Server Preferences
• Deleting server preferences will remove them from our servers but will not affect your local device settings

Data Retention: Server-stored preferences are retained until you delete them or until your account is deleted.

We collect anonymized usage events (screens viewed, features accessed, session duration, and interaction context) to understand and improve how the App performs for the community. These anonymized events are sent to https://api.stash2go.com/api/events for internal usage analysis and product quality reporting. The payloads do not include your name, email, credentials, or other direct identifiers; the data is aggregated to prevent identification of individual users.

Usage analytics are enabled by default (full tracking). You can opt out at any time from within the App by visiting Settings → Legal & Privacy → Usage Analytics. When you disable usage analytics, event reporting to api.stash2go.com stops immediately and no new usage events are sent while tracking remains turned off.

If you opt in to AI-powered features, we may process the following data:

AI Search:

• Your search queries and search history
• Session context and search patterns
• This data is sent to OpenAI to provide intelligent search suggestions

Preference Footprint:

• Your Ravelry projects, favorites, queue, bundles, library, and stash data
• This data is aggregated and sent to OpenAI to generate a personalized preference footprint that improves search results

These features are opt-in only and require your explicit consent. You can enable or disable these features at any time in the App settings. When disabled, no data is sent to OpenAI for these purposes.

Additional AI Features:

• AI Stashing: Helps organize and categorize your yarn stash using AI analysis
• AI Yarn Search: Provides intelligent yarn search suggestions based on your preferences

These additional AI features also send relevant data to OpenAI when enabled. You can control each feature individually in Settings → AI Features.

To help us identify, diagnose, and fix bugs and performance issues, our app uses Sentry for error tracking and performance monitoring.

• Performance data (10% sample rate in production for performance monitoring)
• Session information (session duration, app state)
• IP address (for approximate region)

How This Information Is Used:

This data enables us to:

• Identify and fix bugs and crashes
