Lingle ("we," "our," or "us") respects your privacy. This Privacy Policy explains what information the Lingle iOS app processes, how it is used, and your choices regarding that information.
1) Scope
This Privacy Policy applies to the Lingle iOS application and related services.
2) Information We Process
A. Information You Provide
Depending on how you use Lingle, we may process:
- Profile details (such as first and last name)
- Optional profile photo selected from your device
- Learning content you enter, including:
- journal entries
- translation responses
- quiz answers and written exercises
B. Learning and Progress Data
The app stores learning-related state, including:
- language preferences
- levels, XP, streaks, and challenge completion
- saved vocabulary and saved articles
- tutorial completion status
C. Device Permissions (Optional)
- Photos access (only if you choose to upload a profile image)
- Notifications (only if you enable reminders)
D. Technical and Network Data
When the app communicates with remote services, standard technical information such as IP address, device type, and request metadata may be transmitted as part of normal internet operation.
3) How We Use Information
We use processed information to:
- operate core learning features
- generate journal feedback and translation validation
- create AI-based exercises and benchmarking results
- store and restore your progress
- improve reliability and performance of the app
- send reminder notifications when enabled
4) AI Processing and Third-Party Services
Lingle uses third-party service providers to deliver certain features.
A. AI Processing (OpenAI)
For features such as journal analysis, translation validation, benchmarking, and AI-generated exercises, user-submitted learning content is transmitted securely to OpenAI via its API.
- Only the minimum necessary content required to generate a response is transmitted.
- OpenAI may retain API data for a limited period for security, abuse detection, and reliability purposes in accordance with its policies and applicable law.
OpenAI acts as a data processor for this content.
B. External Content Sources
When the app fetches news or article content from third-party websites, those external sites may independently collect technical information according to their own privacy policies.
5) Data Storage
- On-device storage: Profile data and learning progress are primarily stored locally on your device.
- Remote processing: Content submitted for AI-based features is transmitted to backend services for processing.
6) Data Sharing
We do not sell personal information.
We share data only with service providers necessary to operate the app (such as AI processing providers and infrastructure services).
7) Data Retention
- Locally stored data remains on your device until you delete it or uninstall the app.
- Content transmitted for AI processing may be temporarily retained by service providers for security and reliability purposes.
- We retain backend logs and operational data only as long as reasonably necessary for security, legal compliance, and service integrity.
8) International Data Transfers
Because Lingle relies on cloud-based infrastructure and AI processing services, information may be processed in countries outside your own. We rely on service providers that implement appropriate safeguards consistent with applicable data protection laws.
9) Children
Lingle is not intended for children under 13 (or the minimum age required by local law). We do not knowingly collect personal information from children in violation of applicable law.
10) Your Choices
- You may choose what profile information to provide.
- You may disable notifications in iOS Settings.
- You may avoid submitting content to AI-based features.
- You may uninstall the app to remove locally stored data.
11) Security
We use reasonable administrative and technical safeguards intended to protect processed information. However, no system is completely secure.
12) Changes to This Policy
We may update this Privacy Policy from time to time. The updated version will be posted with a revised “Last updated” date.
