Rungs / App privacy

Privacy in the Rungs app

There is no account and no server. The plan, your child's requests and the records of what happened on the phone are kept on the two phones themselves, and a parent reads them on the child's phone. We never receive them, so we cannot lose them, sell them or hand them over.

This page covers the Rungs app. The website has its own page. Last updated 23 September 2026.

Who is responsible

Humble Loop, a one-person software studio, makes Rungs and is responsible for it. Write to info@ajansmba.com about anything on this page.

What the parent's phone keeps

  • Your child's first name and date of birth, used to work out every date in the plan.
  • The ladder you chose, the house rules you left on, and any rules your child wrote for you.
  • The names of the adults who signed, and the date you signed.

All of it stays in the app's own storage on that phone. Deleting the app deletes it.

What the child's phone keeps

  • The plan that came across from your phone: the name, the date of birth, the dates.
  • The list of apps installed on that phone, read from the phone itself so the home screen can be drawn. It is never sent anywhere.
  • Whether an app that is not open yet in the plan was opened another way, using Android's usage access. This is what tells a parent the plan was worked around.
  • Whether the phone stopped opening with Rungs, and whether it started in safe mode.
  • What your child asked for and the reason they gave, and your answer.
  • The parent PIN, kept as a salted hash — the number itself is not stored — and whether it was entered wrong.
  • What your child made their own: the wallpaper they picked, the colour, the name of the phone.

Nothing on the child's phone connects to us or to anyone else. A notification stays on that phone the whole time Rungs is running; tapping it shows your child the same list a parent sees.

What Rungs never looks at

Messages, calls, photos, what is searched for, what is watched, what is typed, and where the phone is. Rungs does not read them, does not store them and has no way to send them. There is no screen recording, no keyboard logging and no location tracking anywhere in the app.

How the plan gets to the other phone

As a square code on your screen that the other phone's camera reads. The camera is used for that one moment and the picture is not kept. Nothing is uploaded, and the two phones never talk to each other again — later changes mean showing the code again.

What does leave a phone

  • The subscription. Paying happens on the parent's phone through Google Play. Our payment helper, RevenueCat, receives a random identifier for that installation and the receipt Google gives it, so the app can tell whether the subscription is active. It does not receive your name, your child's name or anything from the plan, and no advertising identifier is collected. Nothing on the child's phone uses it.
  • Files you share yourself. The agreement as a PDF and the plan as a calendar file are made on your phone and go only where you send them.

That is the entire list. There is no analytics, no crash reporting, no advertising and no third-party tracking in the app.

Notifications

Reminders are worked out and scheduled on the phone itself, from dates that are already in the plan. There is no push service, so no message about your family passes through anyone's servers.

Children

The customer is the parent; the child uses the phone. We do not ask a child to make an account, because Rungs has no accounts, and nothing a child does in the app is collected by us. What is recorded on that phone is shown to the child as well as to the parent: Rungs is built so a child can always see what is seen.

Deleting everything

Uninstalling removes it all, on either phone, and there is nothing left on our side to remove. The full steps, including the subscription, are on the data deletion page.

Changes to this page

If Rungs ever starts collecting something new, this page says so before that version is released, and the date at the top changes.
