Privacy Policy

Livrarte is an educational app for curriculum practice, exam preparation and the creation of teaching materials.

Data processed may include email, name, nickname, date of birth, optional school, preferred country, game progress, educational metrics, created content and tutor interactions.

In Sportsathon, a student can separately authorise encrypted storage of WHO reference sex, height, weight and measurement date for a private educational chart. These data appear only in the account, can be removed in account options and are not used in rankings, cards, the tutor, advertising or Analytics.

In the Parenting option, an adult who declares they are the legal guardian of minors or have permission from adult children can separately authorise recording a private name or nickname, date of birth, WHO reference sex, and each child’s weight, height/length, measurement position and date. Profiles are encrypted and linked to the responsible adult’s authenticated account. They are not student accounts, are not automatically linked to schools and are not sent to WHO, OpenAI, brands, rankings or Analytics. Calculations run on the device using official tables included in the app. A measurement, a profile or all parenting data can be deleted in settings. Turning the mode off only hides profiles; it does not delete them. This educational guide does not provide diagnoses, diets or adult-height predictions and does not replace clinical care.

When Family reports become available, a copy will only be stored after specific acceptance of the information shown when each report is created. A report may include an encrypted copy of the selected measurements, date of birth and reference sex, together with the date, interval and versions of the reference and consent. CDC reports will also store confirmation of full-term birth. Calculations will run on the device. Up to three reports can be saved and individually deleted. Deleting the child’s profile or all Family data deletes the associated reports; when deleting a measurement, reports containing it can also be deleted. The copy remains until deleted. Technical copies may remain for a limited period after deletion.

Optional educational preferences (sport interest and chosen topic) are stored in the same encrypted profile with the consent date and version. Age and these choices select cards intended for parents; weight, height, sex and percentiles do not select brands, treatments or training plans. At age 18, specific confirmation of the adult child’s permission is required and can be withdrawn without deleting the history. Card answers and session progress remain temporarily on the device and are cleared when leaving the page; they are not sent to AI models or rankings. References and company examples do not imply sponsorship or a purchase recommendation.

When a bibliography reference is marked as useful, livR stores the reaction linked to a pseudonymised account identifier and publishes only the aggregate count. It does not send the reaction to Facebook or show who reacted.

These data are used for authentication, educational personalisation, continuation of games, tutor improvement, management of content created by teachers or Prime accounts, security and technical operation of the platform.

Conversations may be processed by technical services used by the platform, including Firebase and OpenAI, solely to operate the product and improve the educational experience.

Do not enter unnecessary sensitive data in game conversations.

For minors, use must comply with the applicable school, family and data-protection framework.

Requests to access, correct or delete data should be sent to examesnacionais@livrarte.org.
