    Child safety

    The parent manages Wunderli, chooses how a story is shaped and starts playback. The app has no third-party ads, no ad tracking, no open chat and no links that send a child to the wider internet. This page sets out each control and limit plainly.

    No third-party advertising

    No ad network, no ad units, no sponsored characters, and no links out of the app.

    No child profiling

    We do not track children across the internet or build ad profiles from their choices.

    A curated catalogue

    Hero, place, theme, length and level are chosen from a fixed list. The only free-text field is a character name.

    Automated safety check

    Every story passes our own multi-stage safety check before it is narrated.

    What appears during use

    The app opens to story creation and the personal library. There is no feed, infinite scroll or push notification aimed at children. The parent makes the choices with ideas from their child, starts the story and can then turn the screen off while the audio continues.

    What the parent controls

    • The account itself. Sign-in is an adult account, and there are no child profiles.
    • Sharing, reporting and account actions, which are behind a parental gate.
    • Billing, which runs through your App Store or Google Play account and its purchase authentication.
    • Deleting the account and its data, in one flow.

    Privacy by design

    Wunderli is built in Switzerland by a Swiss company. We collect the minimum needed to generate a story and run the account. Where that data is processed, and which safeguards apply when it leaves Switzerland, is set out in the Privacy policy. Delete account explains how to remove it.

    Why audio, not video

    Once an audio story starts, the screen can be switched off. Siblings can listen together without sharing a display, and nothing else begins automatically when the story ends. This is a product choice, not a health claim.

    Try Wunderli safely

    Frequently asked questions

    There are no third-party ads, no ad tracking, no profiling of a child and no open chat. Purchases run through the parent's App Store or Google Play account. Every story goes through our own multi-stage safety check before it is narrated.

    A character name, up to 30 characters, and nothing else. Hero, place, theme, length and language level are all picked from a fixed catalogue we curate, so a child never types a free-form instruction.

    Only the choices needed to produce a story: hero, place, theme, length, language level. No profiling for advertising.

    Very little. A parent picks a few options with their child, then the phone can be put away and the story plays as audio, with the screen dark.
