Your privacy

Version 2026-10-17. This page is for you. It explains in simple words what JARVIS knows about you and how we look after it. Parents can find the longer version for grown-ups on the Privacy page. This English text is a courtesy translation. Only the Czech version is legally binding; if the two differ, the Czech wording prevails.

What we know about you

JARVIS only remembers what it needs so the app works for you and your account stays safe:

  • Your name and the nickname you sign in with.
  • Your year of birth, so we can show you things that suit your age.
  • Whether you are a boy or a girl, so the app uses the right word forms in Czech. Your parent can also choose not to say.
  • The picture you picked as your avatar. We never ask you for photos.
  • Your tasks, chores, goals and rewards, how many coins you have and what you are saving them for.
  • The days you have off from your chores, and why, for example because you were ill or on a trip.
  • What you write in the app yourself, for example a note on a finished task or an idea for a new reward.
  • Which device you sign in from and when. This helps us notice if a stranger tries to get into your account.
  • When you last opened the app, which reminders JARVIS sent you and whether they arrived. We do not write down the text of the reminders or your name with it, and we delete the record of reminders after 90 days. From this and from your age we choose how reminders are written and how often they come: when you do not open the app for a few days, they get more urgent, and when you do not open it for a long time, they stop and at most one a week arrives. If you don't react to reminders for a long time, we send you one last one and after that at most one a week. To know when the last one went out, we save the time it was sent. As soon as you open the app again, we delete that time.

We do not store your PIN the way you type it, only as a scrambled fingerprint. If someone types a wrong PIN several times, sign-in locks for a while so nobody can guess it.

Your account was set up by your parent. For kids under 15, the parent gives consent.

Who can see it

Your things in JARVIS are seen by you and the grown-ups in your family: your parent and other grown-ups your parent invited to the family.

Your real name, the names of your tasks and rewards and your notes are locked with your family's secret key. This is called encryption. Without the key, all anyone sees is a jumble of characters.

The people who run JARVIS do not read these locked family things.

When your parents get a notification or an e-mail, for example that you finished a task, it can include your name. Notifications on an iPhone are delivered by the companies Expo and Apple, e-mails are sent by the company Resend.

Reminders JARVIS sends to you can also include your name. On an iPhone they are delivered by the companies Expo and Apple.

Why we have it

We mainly keep your data so the app works for you: so we can show you your coins, tasks and rewards and so you can save up for your goals.

We keep a record of sign-ins to keep your account safe. When something in the app breaks, it sends us an error report so we can fix it.

We show you no ads and we never sell your data to anyone.

Whether JARVIS may count which screens and features your family uses is decided by the grown-up who set up the family. If a grown-up in your family allows it, your age and whether you are a boy or a girl also go into totals across all families.

On an iPhone, the app also always sends the company Expo an overview of how fast it runs and which of its features are used. None of this includes your name or anything you write in the app.

At 15 and older, you confirm it yourself

From the age of 15, it is not only your parent who gives consent for you. When you sign in, JARVIS shows you a Your data screen and you confirm yourself that you know what we store about you and why.

If you are not sure, you can talk it over with your parent first.

Your parent can download or delete your data

Your data belongs to you. That is why you have these rights:

  • You can ask your parent to show you what JARVIS knows about you. Your parent can download your data as a file.
  • You can ask your parent to fix something, for example your name or nickname.
  • You can ask your parent to delete your data. Once it is deleted, it is gone from JARVIS for good.

If something feels strange or unpleasant, tell your parent right away.

If anything comes up

If you do not know what to do, tell your parent first.

Your parent can then write to us at hey@jarvis.kids. You can write to us too.
