Privacy Policy
Last Updated: April 18, 2025
CapWords (“we”, “our”, or “the App”) is a privacy-first language learning application designed for personal use without requiring any account registration. We do not operate any proprietary servers, nor do we store any personally identifiable information (PII). All data processing is conducted locally on your device or via system services provided by Apple Inc.
This Privacy Policy outlines how we process your information in compliance with applicable data protection laws, including the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and relevant local privacy frameworks.
What Information We Collect and Why
Content you create or provide to us
CapWords is built to minimize data collection. We do not collect or store any personal identifiers such as names, email addresses, phone numbers, precise location, or device identifiers (e.g., IDFA).
During your use of the app, the following technical data may be temporarily processed to enable core features:
a. Camera Access
Purpose: To allow you to capture real-world objects for language recognition.
Data Use: Images are used only once for immediate object recognition and are not saved to your device’s photo library or uploaded to any server.
Storage: No local or remote retention.
b. Image Recognition via Third-Party APIs
Service Providers: OpenAI Vision API and Google Gemini Vision API
Purpose: To identify objects in your captured image.
Data Flow: Images are securely transmitted over TLS-encrypted connections to the selected provider for one-time processing; results are returned immediately to CapWords.
Data Retention: CapWords does not store images. OpenAI and Google each retain request data for up to 30 days solely for abuse-monitoring and safety auditing, after which it is deleted. In neither case are your images used to train their models unless you have explicitly opted in through a separate agreement.

c. Text-to-Speech (TTS)
Provider: Apple iOS AVSpeechSynthesizer (built-in system service)
Purpose: To provide local audio playback of vocabulary
Processing: All synthesis is handled entirely on-device, with no network transmission
d. iCloud Storage via CloudKit
Purpose: To optionally sync user progress (e.g., flashcard history, preferences) across Apple devices
Data Control: Data is stored only in your personal iCloud account, governed by Apple’s privacy terms.
Access: We do not have access to, nor do we control, any iCloud-stored data.
