Local AI conversation requires a compatible iOS device and an available on-device model; it is currently unavailable on Android. Local mode keeps practice content off cloud AI. Keyboard input is available on both platforms.
Scope
This Privacy Policy applies to the EnChat English speaking practice app, related services, and this website (together, the “Services”). EnChat is operated by the ThinkView team. Third-party services such as Apple, iCloud, and DeepSeek may have their own privacy policies and terms.
Information we process
To provide the Services, we may process:
- Learning content: transcripts, messages, corrections, mastery items, practice history, streaks, and weekly reports that you create or ask EnChat to generate.
- Account and entitlement data: an anonymous identifier, session tokens, and subscription entitlements verified through Apple StoreKit or Google Play. EnChat does not collect your payment card details.
- Technical and security data: information needed for authentication, quotas, and abuse prevention, such as IP address, request time, and optional Apple device-integrity signals.
- Website logs: our hosting provider may generate necessary request, error, and security logs when you visit this website. The website does not offer public profiles, comments, or ad tracking.
Voice, transcription, and third-party AI
iOS uses Apple speech recognition; Android uses the system speech service selected on the device. Whether recognition runs on the device depends on the system, device and service settings. Raw recordings are not sent by EnChat to its own AI server. Cloud transcription upload is currently unavailable.
The app presents consent before cloud AI is enabled. Cloud conversation and coaching send recognized or typed text and necessary context; Privacy Enhanced mode reduces the history sent. Local AI conversation requires a compatible iOS device with an available model. On Android, turning off cloud AI stops new replies; existing records and review remain available.
Conversation and coaching may use DeepSeek or Qwen; synthetic speech may use Speechify or Qwen, depending on the service configuration. Providers process the necessary text under their own policies. Do not include passwords, payment details, identity numbers or other unnecessary sensitive information in practice.
How we use information
- To provide conversation, coaching, shadowing comparison, mastery loops, reminders, and reports;
- To retain your learning progress and sync it across devices if you enable iCloud;
- To verify subscription entitlements, enforce practice quotas, prevent abuse, and protect the Services;
- To troubleshoot, improve reliability, and comply with legal obligations.
We do not sell your learning content or use it for targeted advertising.
Local storage and backup
Learning records are stored on the device first. iOS can use iCloud sync subject to device, subscription and account requirements. Android offers optional system backup; backup timing and restoration depend on the device, Google account and system settings. This is not live sync and does not provide unified iOS/Android record syncing.
Retention and your choices
EnChat may retain server-side conversation and reply text audits for up to 90 days for quality and security review. You can withdraw cloud AI consent and delete local records. Deleting local records or uninstalling the app does not delete server text or system backups. Contact smile@thinksview.com for server data or deletion requests.
Children, transfers, and security
EnChat is not directed to children under 13. We use reasonable access controls, token protection, encryption in transit, and data minimization, but no internet service can promise absolute security. The Services may use infrastructure in different countries or regions; information may therefore be processed across borders, subject to applicable law.
Changes and contact
We may update this policy when our features, operations, or legal obligations change. The new version will be posted here with a new date, and material changes will be highlighted in the app or by another reasonable method. Your continued use of the Services means you accept the updated policy.
Contact: smile@thinksview.com. Nothing in this policy limits rights you may have under applicable data protection law.
