Hello! Welcome to the StellKey Privacy Policy.

Vaqstar Sas (“Vaqstar”), a Paris based French company, operates the StellKey Apps and the StellKey websites (www.stellkey.com) (together the “Service”) and is committed to protecting your privacy.

This Privacy Policy (“Privacy Policy”) details the personal data Vaqstar receives about you, how we process it and your rights and obligations in relation to your personal data. Vaqstar, a company registered at 6 rue D’Armaillé, 75017 Paris, France, is the data controller for the purposes of the General Data Protection Regulation (“GDPR”) and any relevant local legislation (“Data Protection Laws”).

By using or accessing the Service, you agree to the collection and use of information in accordance with this Privacy Policy as well as to our Terms and Conditions of Service. As Vaqstar is a company based in the European Union, you also agree that your information could be transferred there.

Information Collection and Use

For a better experience, while using the Service, we may require you to provide us with certain personally identifiable information, including but not limited to name, email and age.

We have limited the number of personnal information collected to a strict minimum to operate the Service efficiently. Our practices with regards to data relating to children are very strict. Altough most data collected are about parents, we also collect your kid’s age to tailor their experiences of the Service. The app does use third party services that may collect information used to identify you but do not include any third party advertising. You can request a copy to review and delete the information Vaqstar has collected about you anytime through an email to privacy@stellkey.com.

We do not collect any information from children. Our website uses “cookies” to collect information and improve the Service.

Child privacy protection

We built our mobile applications in order to comply with the Children’s Online Privacy Protection Act (“COPPA”) and the General Data Protection Regulation (“GDPR”). We don’t knowingly collect personal information from children, unless we previously obtain specific parental consent. We also strongly believe that ads and in-app purchases should not be part of the children’s experience.

Vaqstar allows parents/guardians to set up family account and create profiles for themselves and their children.

Persons under the age of 13 (or any higher age in the jurisdiction where that person resides) are not permitted to create a family account on our Service unless their parent/guardian has consented. If you become aware that your child has provided us with Personal Information without your consent, please contact us. We do not knowingly collect Personal Information from children under 13. If we become aware that a child under 13 has provided us with Personal Information, we will take steps to remove such information and terminate the Child’s Account.

Our App is not directed to individuals under the age of 13, and individuals under 13 are prohibited from downloading our App. Although our App is designed to also be used by a child, our licensee with respect to the App is to the parent/guardian who has downloaded the App and who uses the App.

With regards to the Children’s Online Privacy Protection Rule (“COPPA”), Vaqstar only collects personal information from children under the age of 13 for the sole purpose of performing internal operations of the Service. If we discover that we have unknowingly collected additional personal information from these children we will delete it. If you believe this to be the case, please contact us at privacy@stellkey.com.

Service Providers

We may employ third-party companies and individuals with access to anonymous information for the following reasons:

  • To facilitate our Service;
  • To provide the Service on our behalf;
  • To perform Service-related services;
  • To assist us in analyzing how our Service is used; or
  • To develop new functionnalities and services.

We do not share your information for marketing purposes.


We value your trust in providing us your Personal Information, thus we are striving to use commercially acceptable means of protecting it. But remember that no method of transmission over the internet, or method of electronic storage is 100% secure and reliable, and we cannot guarantee its absolute security.
