Your child. Your family’s information.
Privacy
Callout is a learning game for iPhone and iPad, designed for children aged 6–8 and developed by Mercury Project s.r.o. Children say numbers and picture names aloud to play. This page describes how the Callout app handles information, for the version being prepared for its first App Store release.
In short
- Spoken answers are recognized on the device. Audio is not recorded or transmitted.
- Players, answers, progress, dates and settings are stored locally on the device.
- Mercury Project receives none of this information.
- Callout has no accounts, advertising, in-app purchases or tracking, and does not use a third-party cloud speech service.
Microphone and speech recognition
Callout asks for microphone access because children answer by speaking. The microphone is used during speaking gameplay to hear the answer. Callout recognizes speech on the iPhone or iPad using Apple’s on-device speech recognition (SpeechAnalyzer) and uses the recognized words to check the answer. Audio is not recorded or transmitted, and Mercury Project receives none of it.
You can turn microphone access off at any time in iOS Settings; Callout’s speaking gameplay needs it to work.
Speech language assets
The first time Callout is played in a language, iOS may need to download that language’s on-device speech assets from Apple. This download is handled by iOS, and Apple processes it under its own privacy policy. It does not send your child’s speech to Mercury Project.
Players
Up to six players can use Callout on one device. Each player has an animal avatar and an optional nickname of up to 20 characters. A nickname does not need to be a real name. Players are stored only on the device.
Answers, progress and settings
Callout stores each player’s answers, progress and the dates of play, together with the app’s settings, locally on the device. This information is used to run the game, keep each player’s progress separate and bring earlier prompts back for review. It is not sent to Mercury Project.
Device backups
Like other app data, Callout’s local data may be included in the device’s normal backups, such as iCloud Backup or a backup to a computer, if you use them. Those backups are handled by Apple or by your computer, not by Mercury Project.
Deleting Callout data
Callout does not yet have an in-app option to delete data. To remove all of Callout’s data from the device, delete the app. Device backups made earlier may still contain it until they are replaced or deleted.
Links for grown-ups
Web links in the settings for grown-ups are behind an adult check that asks the user to read an instruction and hold a picture, so children are less likely to leave the app by accident.
No accounts, advertising, purchases or tracking
Callout does not require an account or sign-in. It does not show advertising, offer in-app purchases, include third-party analytics or tracking, or send speech to a third-party cloud speech service.
Support messages
Support email is separate from the app. If you email us, we receive your email address, your message and any attachments you send, and use them only to respond to your request. Please don’t send recordings of your child or other personal details about them unless they are needed to resolve the issue.
This website
These pages contain no analytics scripts, advertising scripts, forms or third-party fonts. The website is separate from the app: its hosting provider may process ordinary request information, such as IP addresses and server logs, to deliver and operate the site. The app does not send your child’s data to this website.
