Our Commitment to Children's Privacy

Protecting the privacy of young children is especially important. If GeoGebra learns that personally identifiable information of children has been collected on the Website without parental consent, then GeoGebra will take the appropriate steps to delete this information. If you are a parent or legal guardian and discover that your child has a registered account with the Website without your consent, then you may alert GeoGebra at and request that GeoGebra delete that child's personal information from its systems.
In particular, we never share the personal information of any user with third parties.
It's important to remember that you do not need to register or sign in to the Website in order to use the GeoGebra software and access millions of GeoGebra resources.

Compliance with COPPA

GeoGebra complies with COPPA, the Children’s Online Privacy Protection Act (COPPA) which is a United States federal law designed to protect the privacy of children under 13.

Our services offered at are intended for use by students, also including students under the age of 13. GeoGebra does not collect personal data without the permission of a parent, school etc. Please get in touch with us via if you think that GeoGebra has accidentally collected personal data from a child younger than 13 and we will make sure that the stored information is removed.

Compliance with FERPA

The Family Educational Rights and Privacy Act (FERPA) is a federal law that protects the privacy of student education records. FERPA requires education institutions and agencies to obtain written permission from the parent or eligible student in order to release any information from a student’s education record. Here are some recommendations how our policies can help those institutions and agencies to meet the requirements under FERPA:

GeoGebra products can be used by any individual and GeoGebra is not notified when our products are used.

Student's work is only saved on GeoGebra when the student (or student's parents for age under 14) has created a GeoGebra account. This work can be accessed by parents and eligible students under FERPA. If you are a parent and discover that your child has a registered account without your consent, then you may request that GeoGebra deletes that child's saved work and account.

Google reCAPTCHA v3: This website uses "Google reCAPTCHA" (hereafter "reCAPTCHA"). Provider is Google Inc., 1600 Amphitheater Parkway, Mountain View, CA 94043, USA ("Google"). With reCAPTCHA we want to check if the data entry on our websites (for example in a contact form) is done by a human or by an automated program. For this, reCAPTCHA analyzes the behavior of the website visitor based on various characteristics. This analysis begins automatically as soon as the website visitor enters the account registration process. For analysis, reCAPTCHA evaluates various information (for example, the IP address, the website visitor’s visit time on the website, or user mouse movements). The data collected during the analysis will be forwarded to Google.
The reCAPTCHA analyzes are completely in the background. Site visitors are not advised that an analysis is taking place.
The data processing is based on Art. 6 para. 1 lit. f GDPR. The Web site operator has a legitimate interest in protecting its web sites from abusive automated spying and SPAM.
