Privacy Policy

This Privacy Policy explains how we collect, use, and share information when you use Sentence Master (the “Service”).

Information We Collect

• Account data (optional): email, display name, profile photo (if you choose to add one).
• Learning data: practiced patterns, examples, answers, scores, streaks, reminders, in‑app preferences.
• Content you submit: sentences you type or speak for exercises and any feedback messages you send us.
• Voice & microphone: if you enable speaking practice, audio samples are processed to do speech recognition and pronunciation scoring. Audio may be handled on‑device or sent to our servers or processors strictly to provide the feature.
• Device & diagnostics: device model, OS, app version, anonymous identifiers, event logs, crash reports, and performance data.
• Purchase info: receipts and status from Apple/Google necessary to unlock premium features (no full card details).
• Website data: standard web logs and cookies or similar technologies for basic operations and analytics.

How We Use Information

• Provide and personalize practice, review scheduling, and progress tracking.
• Operate AI features (grammar feedback, pattern suggestions, speech analysis).
• Measure performance, fix bugs, and improve reliability and usability.
• Send service communications (e.g., changes, security notices). You can opt out of non‑essential emails.
• Comply with law and enforce our Terms.

Processing Locations & International Transfers

We may process data in countries different from where you live. When transferring personal data internationally, we use appropriate safeguards where required by law.

Sharing and Disclosure

• No selling of personal data.
• Service providers: hosting, analytics, crash reporting, messaging, and speech/AI processors — bound by confidentiality and data‑use limits.
• Legal and safety: if reasonably necessary to comply with law, protect individuals, or maintain the security of the Service.
• Business transfers: in a merger, acquisition, or asset sale, data may transfer as permitted by law, with notice where required.

Retention

We keep personal data only as long as needed for the purposes in this Policy, including providing the Service, complying with legal obligations, resolving disputes, and enforcing agreements. You can ask us to delete your data at any time.

Your Choices & Rights

• Access, correction, deletion: email smile@thinksview.com.
• Opt‑outs: disable analytics/crash reporting where available in settings; unsubscribe from non‑essential emails; manage reminders in your OS settings.
• Do Not Track: because there is no common industry standard, we do not respond to DNT signals.

Region‑Specific Notices

EEA/UK (GDPR)

We process personal data under these legal bases: performance of a contract (providing the app), legitimate interests (security, improvement), consent (optional features, such as certain analytics or voice processing modes), and legal obligations. You may have rights to access, correct, delete, or port your data and to object or restrict certain processing.

California (CPRA)

We do not “sell” personal information as defined by CPRA. California residents may request access, correction, or deletion of personal information and may limit the use and disclosure of sensitive personal information subject to applicable exceptions.

Children

The Service is not directed to children under 13 (or the minimum age in your country). If we learn we collected personal data from a child without verifiable parental consent, we will delete it.

Security

We use reasonable technical and organizational measures to protect personal data. No method of transmission or storage is completely secure.

Changes to This Policy

We may update this Policy from time to time. If changes are material, we will provide notice in‑app or by email when appropriate. The “Effective date” above will reflect the latest version.
