Privacy policy for the Yo Bro app
Last updated:
This policy is about the Yo Bro app for iPhone, iPad and Android. The website you are reading is covered by the Savage Software privacy policy.
In short
- Yo Bro has no account, no advertising, and no analytics or tracking.
- We receive no personal data from the app. There is no Yo Bro server.
- Word lists, scores, badges and settings are stored only on your device.
- A backup file is yours to make, and notifications stay off until you switch them on.
Who we are
Savage Software is the sole proprietorship of Sebastiano Bellinzis, registered with the Dutch Chamber of Commerce (KvK) under number 87535718. Savage Software makes the app and is the controller for it. You can reach us at [email protected].
What stays on your device
Your word lists, your picture lists, scores, badges, how far along every maths chapter is, and your settings are stored only on your device. They are not sent to us or to anyone else. Deleting the app deletes them — unless you made a backup file yourself (see below).
Camera and photos
The camera is used only to photograph word lists and to scan list codes. The picture is read on the device, and it is not stored or sent anywhere.
If you pick a picture from your photo library, the app reads only that picture, and it reads it on the device.
Text recognition
On iPhone and iPad, the words are recognised with Apple’s Vision framework, on the device. Nothing leaves the device.
On Android, the words and list codes are recognised with Google’s ML Kit, which runs on the device through Google Play services. The photo and the words are not sent anywhere.
ML Kit itself does send Google diagnostic information, such as the device model, the operating system version, the app’s package name and version, performance and error data, and an identifier for each installation. Google uses it to keep ML Kit working and to improve it. Savage Software does not receive this information. Google explains what is collected in its ML Kit data disclosure.
Battles
In a battle, phones on the same local network connect directly to each other. The words of the list, the answers and the animal each player chooses go only between those phones. Nothing goes over the internet. On iPhone and iPad, the app asks for permission to use the local network for this.
Sharing a list with a QR code
When you share a list with a QR code, the list is inside the code itself. Nothing is uploaded.
A backup file
Settings can put everything the app knows about you into a single file: your lists with their words, how far along every word is, your badges and your settings. You make that file, and you decide where it goes — your own storage, your mail, a chat. We never see it; the app sends it nowhere. It is plain text, so you can read it yourself. Putting it back on another phone brings everything back without anything having been stored along the way.
Your phone's own backup may also carry the app's data, so that a new phone gets your lists back. That is your phone's doing, with your Apple or Google account, under their terms.
Notifications
The app can tell you one thing: that a list you gave a test date to is tested tomorrow. One message, the evening before. It never sends any other notification.
This is off until you switch it on in Settings. Only at that moment does the app ask your phone for permission, and if you say no it stays off. The alarm sits in your phone: no server is involved and nothing about you or your child leaves the device. Switch it off again and the scheduled messages are removed at once.
Reading words aloud
Words are read aloud by your phone’s built-in text-to-speech. Some voices offered by the phone’s maker may use the internet; that is between you and that provider.
The subscription
The Yo Bro Pro subscription — by the year or by the month — is handled entirely by the App Store or Google Play. We never see your payment details. The app only keeps, on the device, whether a subscription is active, and the store confirms that every time the app starts.
Children
Yo Bro is made for school children, and it collects no personal data from them. Parents can require their approval for purchases in the store’s family settings: Ask to Buy on Apple devices, Family Link on Android.
Your rights
Because we hold no data about you, there is nothing for us to show you, correct or delete. For data that Apple or Google process, their own privacy policies apply: the Apple Privacy Policy and the Google Privacy Policy.
