FOR PARENTS & GROWN-UPS

Privacy, plainly explained

This explains the Dino Letter Hunt iPhone and iPad app, this informational website, and the separate web beta.

Updated 18 September 2026

The iPhone and iPad app

The iPhone and iPad app stores learning progress, collected dinosaurs and pictures, and preferences locally on the device. It does not require an account and does not include advertising or app-added analytics. The app does not request microphone, camera, or location access. The app does not transmit this learning progress to us.

Hope’s prepared voice recordings, pictures, and hatch animations are included in the app. The native app does not send a child’s speech to a voice service or use a browser voice. Learning progress does not sync between devices or transfer from the web beta.

Resetting progress starts a new collection on the device. It is not a secure-erasure tool: local recovery data may remain. Deleting the app removes its app data from that device, though device backups are managed separately by Apple and your device settings. Apple may separately process installation, diagnostic, and TestFlight feedback information under Apple’s policies. Avoid including children’s identifying information in feedback.

This informational website

The website explains Dino Letter Hunt and links to the separate playable beta. It has no signup form, advertising, added analytics, or account system. The website’s own code does not store a visitor profile or ask for a child’s name.

Images, fonts and scripts are served with the website. Viewing a page or following the play link still makes a normal network request to the relevant host.

The separate web beta’s local explorer book

The web beta saves completed letters, visits, collected pictures, completion dates, practice information such as misses or hints, and sound, motion and learning preferences in this browser’s local storage. The game does not ask for a child’s name, email address, microphone, camera or location.

The game code does not send this saved progress to an account or analytics service. It stays with this browser and device; it does not sync across devices. If storage is unavailable, a session may only keep progress temporarily.

Audio in the separate web beta

The web beta plays prepared recordings, including letter sounds. It downloads these audio files from the game’s host; it does not create a new voice recording while your child plays.

For some ordinary words or narration, the game can fall back to the browser’s speech service if a recording cannot play. The browser or operating system may use a local or a remote voice. A remote voice service may receive the fixed text being spoken and connection information. The child is never asked to speak or send an audio recording. Letter phonemes use recorded clips rather than an unverified browser pronunciation.

Hosting and technical information

Both web pages are currently hosted through ChatGPT Sites, with Cloudflare infrastructure. The hosting and security services may process technical information such as IP addresses, browser details, requested file paths, timestamps, and security cookies needed to deliver and protect the sites. We cannot promise that visiting a hosted website involves no data processing.

We have not added third-party advertising, tracking pixels or analytics to either site. Provider security and operational records are separate from the explorer book saved by the game. Their retention is controlled by those providers, not by the game’s reset button.

Your choices

• Use the game’s speaker button to turn sound off, and Grown-ups settings to adjust animation and learning options.
• In the iPhone and iPad app, use the parent-gated reset in Grown-ups to start a new collection. Resetting needs confirmation. In the separate web beta, hold to review a reset or choose “Reset using confirmation,” or clear the game’s site data through your browser.
• Clearing site data, switching browsers, or ending a private-browsing session can remove or hide the web beta’s saved progress. Dino Letter Hunt has no account-based recovery or developer-operated cloud sync.

Questions and changes

A parent or grown-up can contact Marcello Cavallo about support or privacy at support@dinoletterhunt.com. If you email us, your email address and the message you choose to send are used to respond to your request. Please do not send a child’s name, photo, voice recording, or other identifying information. The parent help page explains what is useful in a technical report. TestFlight testers can also use Send Beta Feedback.

We delete support emails within 90 days after the request is resolved. We also honor requests to delete a support conversation; email support@dinoletterhunt.com to request deletion.

We will update this page if the app’s data handling changes. The app is currently available for testing through TestFlight; its public App Store release is being prepared.
