LexiJump is designed for children aged 4–9. We do not collect any personal information that could identify your child. We collect only anonymous, aggregated usage data to improve the learning experience.
LexiJump ("the App") is a vocabulary learning application for children, operated by WonderYears LLC ("we", "us", "our"). This Privacy Policy explains what information we collect, how we use it, and how we protect it. We comply with the Children's Online Privacy Protection Act (COPPA) and applicable child privacy laws.
LexiJump does not collect any personally identifiable information. Specifically, we do not collect:
To understand how the App is used and improve the learning experience, we collect the following anonymous, non-personal usage data:
| Data | Purpose |
|---|---|
| Age band (e.g., "4–6" or "7–9") | Ensure content is age-appropriate |
| Words viewed and video completion | Understand which content is most engaging |
| Quiz answers (correct/incorrect) | Measure learning effectiveness |
| Session duration | Monitor healthy usage patterns |
| Content category browsed | Improve content organization |
| App version | Diagnose technical issues |
| Random session identifier | Group events within a session (not tied to any device or person) |
Important: The session identifier is a randomly generated ID created by the App. It is not derived from any device identifier, Apple ID, or personal information. It cannot be used to identify any individual user.
We do not collect the child's exact age — only a broad age band (4–6 or 7–9). We do not use any third-party analytics SDKs, advertising frameworks, or tracking technologies. All analytics are sent directly from the App to our own servers.
We use the anonymous usage data solely to:
We do not sell, share, or transfer this data to any third party. We do not use this data for advertising or marketing purposes.
Anonymous usage data is transmitted via encrypted HTTPS and stored on secure servers provided by Amazon Web Services (AWS) in the United States. Data is automatically deleted after 12 months. We implement appropriate technical safeguards to protect the data we store.
The App stores the following data locally on your device only:
This local data is not transmitted to us or any third party. You can delete it at any time by deleting the App or using the "Reset Progress" feature in Parent Settings.
The App downloads educational content (word definitions, icons, and videos) from our content delivery servers (Amazon CloudFront). These are standard HTTPS content downloads. We do not log or retain IP addresses or any identifying information from these requests.
LexiJump is designed for use by children aged 4 to 9, under parental supervision. We are committed to complying with the Children's Online Privacy Protection Act (COPPA) and take the following measures:

These reports contain technical information about the crash (e.g., which line of code failed) and do not include personal information. This is governed by Apple's Privacy Policy.
LexiJump may offer optional subscription purchases. These transactions are processed entirely by Apple through the App Store. We do not receive, process, or store any payment information. Apple's privacy policy governs the handling of payment data.
LexiJump does not integrate any third-party SDKs for analytics, advertising, or user tracking. The services we use are:
