Privacy policy

The short version

• The app works offline. It has no server and sends no data to us or to anyone else.
• The microphone is used only during games. The sound is processed on the device and never recorded.
• We never ask for a child's name, photo, location or contact details.
• There are no ads, no analytics and no trackers, in the app or on this website.
• Parents can see, export and delete everything stored on the device.

1. Who we are

Hoplavox is created by Georges Byona and published through the LosingTek studio (losingtek.com), referred to as "we" in this policy. For any question about privacy, write to hello@hoplavox.com.

2. What this policy covers

This policy covers the Hoplavox app on Android, iPhone and iPad, and the website hoplavox.com. The stores you download the app from (Google Play and the App Store) have their own privacy policies, which apply to your store account and purchases.

3. What the app keeps on the device

To work and to show progress to parents, the app saves the following information in its private storage on the device:

• Settings: the app language, the game language, and options such as tolerant checking, the microphone bar and unlocked levels.
• A label for each child, such as "Child 3 · 4 years", made of a number from 1 to 8 and an age from 3 to 10. Never a name.
• Stars earned per child, game, stage and level.
• The results of each answer: the game, stage and level, the date, the expected answer, what the speech engine understood (a few words as text, or a measure such as a breath length or a note accuracy), whether it was right the first time, and the response time.

This information never leaves the device unless a parent chooses to export it. We have no way to access it.

4. What the app never collects

• Audio recordings of any kind.
• Names, photos, videos, email addresses or phone numbers.
• Location, contacts, calendars or files from the device.
• Advertising identifiers or device identifiers used for tracking.
• Usage analytics, crash reports sent to a server, or any data sold or shared with third parties.

5. The microphone

The app asks for the microphone permission because children play with their voice. The microphone is open only while a game waits for an answer. It is closed while the frog speaks and released as soon as the game ends or the app leaves the screen.

The sound is analyzed in real time, in the device memory, by a speech recognition engine built into the app. It is turned into text or into a measure (a note, the length of a breath), then discarded. No audio is ever written to storage or transmitted.

If you refuse the permission, the voice games cannot be played, and you can allow it later in the device settings.

6. The motion sensor

The balance game reads the tilt of the device from its accelerometer, which needs no permission. The tilt is used live to move the little man and is not saved; only the result of each crossing is kept in the results.

7. No internet, no third parties

The speech models, voices, sounds and drawings are all inside the app. The app does not connect to the internet to work, and on Android the released app does not request internet access.

The app contains no advertising, no analytics, no social network integration and no third-party tracking code. Open-source components used by the app, such as the speech recognition engine, run entirely on the device.

8. Children

Hoplavox is designed for children aged 3 to 10 and for the adults who look after them. We do not knowingly collect any personal information from children, and the app is built so that no personal information about a child leaves the device.

Hoplavox is designed to meet the US Children's Online Privacy Protection Act (COPPA), the European General Data Protection Regulation (GDPR) and its rules on children's data, and the requirements of the Google Play Families program and of the Kids category of the App Store.

The settings and the parent dashboard are protected by a parental gate. No purchase can be made from inside the child's games, and no external link is offered to the child.

9. Your control and your rights

Because all the data stays on the device, parents control it directly:

• See: the parent dashboard shows every result, per child, language, game and day.
• Export: the results can be exported as a JSON file, which you decide where to keep or share.
• Delete: the clear button in the dashboard deletes every result, and uninstalling the app deletes all its data.

Depending on where you live, you may have rights to access, correct, delete or move personal data, and to complain to a data protection authority. Since we receive no data from the app, we hold none to give back, but we will answer every request sent to hello@hoplavox.com.

10. Security and retention

The data is kept in the private storage of the app, protected by the operating system, which other apps cannot read. We recommend protecting the device itself with a lock code.

The data is kept until a parent clears it or the app is uninstalled.

11. This website

hoplavox.com has no analytics, no advertising and no tracking cookies. If you switch the language of the site, a small cookie named NEXT_LOCALE remembers your choice for one year; it is strictly necessary for the feature you asked for and contains nothing else. The "play on your phone" card remembers that you closed it in your browser's local storage, which never leaves your browser.

The site is hosted by Vercel, which processes technical data such as IP addresses in its server logs to deliver the pages and protect them from attacks, for a short period and under its own privacy policy. We do not use these logs to identify or follow visitors.

12. When you write to us

If you send us an email, we use your address and your message only to answer you. We keep them as long as needed to follow up, then delete them. We never add you to a mailing list without your clear consent, and we never share your message. Please do not send recordings of your child or their full name: we do not need them.

13. Future features

A family backup between devices may be offered later. If it is, it will be optional and off by default, turned on only by a parent behind the parental gate, and this policy will be updated before the feature is released, explaining exactly what is sent, where and why.

14. Changes to this policy

If this policy changes, we will update the date at the top of this page, and announce any important change in the app or on this website before it applies.
