How it works

Three steps. Then we get out of the way.

You shouldn't have to audit a device every night. Gakudo works in the background and only speaks up when something deserves your attention.

01Link

Connect the first phone in 3 minutes.

Scan a QR from your kid's device. Nothing to root, nothing installed behind their back — everything in the open.

02Configure

Rules that make sense, per child.

School hours, breaks, quiet nights, web filtering. Age-based templates to start from; you fine-tune the rest.

03Accompany

One daily digest, not constant notifications.

A calm summary every evening. If an unusual pattern shows up, we tell you with context — never with fear.

Product

Three things we do. And many we don't.

We decided what not to build before deciding what to build. The result: a tool that understands your kids are people, not projects.

01 · Patterns, not content

We detect risk without reading messages.

We evaluate frequency, intensity and context of device usage. Never the literal text of a chat, never a screenshot.

  • On-device analysis when possible, cloud when not.
  • Clear signals: "calm day", "rhythm change", "unusual pattern".
02 · Family rules

Screen time that respects real life.

Templates by age and routine; fine adjustments per child. School time, dinner, the night — the device knows when it's not its moment.

  • App blocking by time window, not by day.
  • Explicit exceptions: homework, calls to grandma, trips.
  • No confusing dialogs: if you enable it, it applies now.
03 · Calm, not alerts

One daily digest. When something matters, it comes with context.

Constant notifications create anxiety and rarely help. We send one digest at the end of the day and only interrupt when it matters.

  • At most one push notification a day, barring emergencies.
  • Every signal includes "what changed" and "what you can do".
  • No vanity dashboards. No metrics you'd never use.
Privacy by design

Your family is not our business model.

We charge a fair subscription. We don't sell data, we don't train general models on children's conversations, and we don't share metrics with ad networks. Period.

We never read content

We work with usage metadata: when, how much, how often. Never the text of a message, never what was watched.

FAQ

What parents ask us most.

Missing something? Write to hello@hiramekistudios.com. Humans answer, not templates.

Is this a spy app?
No. A spy app reads device content behind the child's back. Gakudo is installed with the child's knowledge, doesn't access message text or photos, and always shows what it's observing. The verb is accompany, not surveil.
Which devices and operating systems do you support?
iOS 16 or later, Android 12 or later, and a desktop browser for the family console. Coming next: managed Chromebooks and Nintendo Switch.
How do you handle my child's data?
We only process usage metadata (time, frequency, app categories), stored encrypted on EU servers. Consent from children over 14 is mandatory; between 7 and 14, informed consent is requested and documented in the family account.
How many kids can I link?
The free plan includes 1 child and 2 devices. The Family plan includes up to 4 children and 8 devices, plus co-parents with differentiated permissions.
Can I cancel and delete everything?
Yes, anytime from Settings → GDPR. Cancellation is immediate with no penalty; full deletion runs within 72 hours and backups expire after 30 days.
