Linberry Privacy Policy
What Linberry does
Linberry helps you study languages, save learning points, practice, create audio lessons, and work with selected text through its sharing and translation extensions. Linberry does not require a Linberry account. You connect your own AI services. Linberry does not include advertising or an analytics SDK, and does not use your data for cross-app advertising tracking.
Data stored on your device
Linberry stores your conversations, selected-text captures, saved learning points, review progress, study preferences, user memories, generated files, podcast scripts and cached audio in its app storage or its shared App Group. The App Group lets Linberry and its sharing and translation extensions use the same settings, consent choices and learning data. New extension conversations are currently retained separately from the main conversation history. API keys and service connection tokens are kept in the system Keychain on iOS and macOS. Device backups managed by Apple or by you may include app data; Linberry does not provide its own chat cloud-sync service.
iCloud synchronization
In Settings > Sync, you can enable Knowledge synchronization to store learning points, notes, review progress and learning preferences in your private CloudKit database under your Apple iCloud account. When iCloud is available, supported non-secret AI provider connection settings synchronize automatically in a separate private CloudKit zone. API keys are not stored in CloudKit. Optional API key synchronization uses iCloud Keychain after a separate confirmation. Subscription login tokens and local server credentials remain on the device. Conversation history, generated media and podcast audio are not synchronized by these options. Apple processes iCloud data under its own privacy practices. Turning Knowledge or API key synchronization off stops that optional syncing; it does not erase copies already stored in iCloud or on other devices. Deleting a learning point while Knowledge sync is enabled synchronizes that deletion.
Saved user memories
Manual memory is unavailable in this version, and automatic Agent memory is not enabled. Previously saved memory files are retained locally and are not used for new memory recall. Saved conversation text may still contain information discussed previously; hiding memory does not erase conversation history.
When data leaves your device
Before sending learning content to AI services, Linberry asks for explicit permission and identifies the services. Your selected AI service receives your submitted messages, relevant conversation history, learning preferences and relevant saved learning points. Supported attachments and referenced images may be sent to the configured service when you use the corresponding capability. Text selected in another app is used when you explicitly send it through Share or Translate. The shipping app does not include the experimental keyboard and does not monitor everything you type in other apps.
Vocabulary image search sends necessary search phrases, language and domain hints to Wikimedia Commons or ARASAAC when enabled. Their image servers receive picture requests and normal connection information. Image descriptions, not picture bytes, are returned to the selected text AI service for matching.
Optional web search sends search queries to the configured search service, such as Exa. Tool queries can contain information from your request or learning context. Pronunciation and audio lessons send the text to be spoken to Microsoft's Edge read-aloud service. Other agent speech and image tools use the providers you configure. Your chosen local model server receives the requests sent to its address. A local server can itself use remote services, depending on your configuration.
Service credentials are used to authenticate requests to the relevant service. Network services necessarily receive connection information, such as your IP address. Linberry does not send your study archive to a developer-operated Linberry server. Third-party services can have their own logging, retention, training and deletion practices. Review the policy for each service and your account settings before connecting it; avoid sending sensitive information you do not want that service to process.
Camera, microphone, photos and files
Linberry requests camera or microphone access only when you choose to capture media for language practice. It can use the system photo or file picker to attach items you select. Saving an image to Photos requests add-only photo-library permission. Selecting or recording a file does not itself mean that an AI service can understand it; only supported content is processed. A local-model connection may request local-network access. You can manage these permissions in system Settings.
Your choices and deletion
You can cancel the AI permission prompt before content is sent. In Settings, open Policy and choose Revoke AI data sharing permission to clear the saved consent; the next AI request asks again. Revocation does not recall requests already sent or erase a provider's records. Stop any active request if you no longer want it to continue.
You can delete saved learning points, inactive conversations and podcasts using the app's controls. You can export your study data from Settings > Your data on iOS or Export Study Data on Mac. Exported files and copies you share with other apps are controlled by you and those apps. Local generated files and caches can remain in app storage. On iOS, removing the app removes its local app container. On macOS, moving the app to Trash can leave its local data. Shared App Group data, iCloud data and Keychain items can remain after removing an app; disconnect providers and manage cloud data separately. For deletion of data held by an AI, search, speech or image provider, use that provider's account controls or contact it directly.
Support requests
If you email [email protected], Flamesilk LLC receives the information you choose to include, such as your email address, app version, error details and screenshots. It is used to answer your request and investigate the issue. Do not include API keys, passwords or private conversations. Support correspondence is retained for resolving and following up on requests; contact the same address to request deletion, subject to applicable recordkeeping obligations.
Children and AI output
Linberry is a general language-learning tool and is not designed specifically for children. AI responses can be inaccurate or inappropriate. Check important explanations and translations, and report a concern to [email protected] without including unnecessary personal information.
Policy updates
This policy can be updated when the app's data practices change. The effective date identifies the current policy. Material changes to the services or content shared require appropriate disclosure and permission. Contact [email protected] with privacy questions.
