A calm-response system of 22 protocols, 2 deep-dive guides, and 6 tools, designed to help parents stay calm in the hardest 30 seconds with their child.

Kidley is built for ages 2 to 10. That's the developmental window where the "warm-and-firm" method actually works.

• 2 to 4 years: language is exploding, first big tantrums, sleep regressions, potty-training. The child can hear scripts but can't self-regulate yet, which is precisely when calm parental scripting matters most.
• 5 to 7 years: rule-testing, drop-off anxiety, sibling rivalry, screen battles. Anchor sentences and predictable limits become the spine of the household.
• 8 to 10 years: independence-seeking, friendship complications, lying, big feelings dressed up as attitude. Repair scripts and longer conversations replace short ones.

Why not under 2? Pre-verbal regulation is a different toolkit (mostly attunement and routine).

Why not over 10? Tween years need a different approach focused on autonomy and identity. Both are on the roadmap but not in v1.

Every protocol includes age-band nuance so the language adapts to your specific child within that 2-10 window. The deep-dive guides (Potty, Sleep) start younger; the daily content (game, question, word, cultural practice) auto-adjusts to your child's age once you tell us in onboarding.

Books teach. Kidley prompts. The four moves and the 22 protocols are practised before the room gets loud, then surfaced at the moment you need them, with the exact one-sentence script and the five-step sequence. Books live on a shelf. Kidley lives in the pocket you reach for at 6pm.

A guided box-breath (4 in, 4 hold, 6 out, 2 rest) that runs for 5 minutes. Tap the orange orb to start and pause. Liu meditates in the centre as a visual anchor. Open it from the homepage pill, the Tools page, or any protocol's "Start 5-min reset" button.

No. Kidley is content, not a service. For health, behaviour, or developmental concerns, please consult your paediatrician, GP, or a licensed mental-health professional.

Everything you have in the playbook on day one stays yours forever, whether or not you keep Kidley+.

All purchases are final. Read the sample protocols and the Foundations chapter on this site before you buy, so you know what you're getting. See Terms →

Today, your profile and saved library live in the browser of the device you set them up on. Cross-device sync (so your library follows you from phone to laptop) arrives in the next release. Your access to all the content works on any device immediately.

For the founding launch, one purchase grants access to one household. Both parents (and any other primary caregivers) can open the app on their devices. Once accounts and sync go live, we'll formalise this into a clean "family plan" model that doesn't cost extra for founding members.

In your own browser's local storage. We don't have a server-side copy. We don't sell or share your data. See Privacy →

No analytics, no advertising trackers, no third-party scripts beyond Netlify hosting and a read-only Google Sheet for the daily content. Nothing about your behaviour leaves your device.

Your local profile and saved library are gone. The content itself is unaffected, you just go through onboarding again and start saving. Once cross-device sync is live (next release), this stops being a concern.

Anything modern: Safari 14+, Chrome / Edge / Firefox latest. Mobile Safari (iOS 15+) and Chrome Android (latest) are fully supported. The app works offline once it's loaded, you can run the breathing tool on a plane.

Not yet. Kidley's warm palette is part of how it communicates calm, most calming-content apps don't ship dark mode for the same reason. If founding members ask for it, we'll add a properly designed dark theme.

From the homepage's search bar, if you type something we don't have a protocol for yet, you'll see a "Request a protocol" button. We read everything submitted. Or email hello@kidley.app.
