    Child safety

    A bedtime app has to earn a spot in the child's room. That means being explicit about what is not in there: no third-party ads, no ad tracking or profiling of a child, no open chat, no shortcut to the outside internet. Here is what safety looks like inside Wunderli.

    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 kids actually see

    A single, calm home screen with a big "make a story" button, plus their story library. No feed, no infinite scroll, no push notifications aimed at children. Once a story starts, the screen can be turned off. That is the point: audio, not another screen.

    What sits with the parent

    • 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

    An audio story asks a child to picture things rather than watch them, needs no screen light once it starts, and lets siblings share the same story without crowding a display. That is a design choice we made, not a health claim: if you want the evidence on screens before bedtime, read the guidance from your own paediatric association.

    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 writes a free-form prompt to the AI.

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

    Very little. Kids pick a few options, then the phone can be put away and the story plays as audio, with the screen dark.
