The EdTech Proposal That Didn't Come Back with Questions

Ms Mehta is head of a 420-pupil primary. She evaluates EdTech proposals through a standard mental checklist: CPD requirement, IT overhead, data/GDPR exposure, cost, and evidence of genuine educational value. Most tools fail on at least two criteria. Several fail on three.

Kidoku came to her attention through a maths lead who had been using it in Year 5 for three weeks. She asked the routine questions. CPD required: none. The game is self-explanatory. Teachers had never asked her about it, which meant they hadn't needed support. IT overhead: none. Browser-based. No school network configuration. Her IT coordinator hadn't heard of it, which was a good sign.

GDPR: this was the question she expected to return complexity. The answer was architectural, not contractual. Kidoku doesn't collect student personal data because it doesn't use student accounts. Auto-generated usernames. Session results are ephemeral. No DPA required beyond standard processor notification because no personal data is processed. Her DPO's review took eleven minutes.

Cost: free tier for evaluation with no time limit. School pricing available if the evaluation result is positive. She didn't need to involve finance for the evaluation phase.

Educational value: the maths lead provided session data showing 94% of students completing sessions, average time-on-task of 18 minutes, and teacher reports of increased engagement in logical reasoning tasks in the following lesson. That was the evidence she needed.

She approved the expansion from one class to a school-wide free tier in week four. The only question IT asked was whether they needed to whitelist the domain. The answer was yes. It took them three minutes.

Every Item on the School EdTech Checklist

School leaders evaluate tools against consistent criteria. Kidoku was designed with each criterion in mind.

📋

CPD Requirement: Zero

Teachers use Kidoku without training. The classroom mode is a link and a room code. No instructional sessions, no video tutorials, no teacher handbook. If a supply teacher can run it in an unfamiliar classroom, your permanent staff can run it without CPD.

🖥️

IT Overhead: Whitelist One Domain

Browser-based. No install, no app management, no server. Your IT coordinator's entire involvement is to whitelist kidoku.app if your network filter requires it. Estimated IT engagement: three minutes. No ongoing maintenance.

💰

Evaluation Cost: Free

The free tier is genuinely functional — not a limited demo. Evaluate in a real classroom context with no time pressure. School pricing for expanded access is available once the evaluation period produces a decision.

GDPR-Safe Because No Data Is Collected

shield

No Student Accounts

Students don't create accounts. No name, email, age, year group, or school name is collected at any point. Auto-generated usernames (CoolFox32) are the only identifier. Session-scoped. Not stored after the session ends.

No Personal Data Processing

Without personal data, there's no data processing relationship to document in the traditional EdTech sense. Standard processor notification applies. Your DPO doesn't need to negotiate a bespoke DPA.

Safe for All Year Groups

The privacy architecture means Kidoku is safe for use in EYFS, primary, and secondary without age-differentiated data handling. No consent process, no parental opt-in, no content moderation regime required.

Free to evaluate. Zero IT overhead. Zero CPD budget. Teachers deploy it without asking for help. If it works in your school, you already know the cost of doing nothing: another lesson of disengaged students and another EdTech investment that required six months of support to run.

FAQ

Frequently Asked Questions

Everything you need to know about Kidoku Live for this use case.

Does Kidoku Live require a GDPR data processing agreement?

No DPA is typically required because Kidoku Live collects zero student personal data by design. There are no student accounts, no names, no emails, no persistent identifiers. Without personal data processing, there is no data processor relationship to formalise. Most school DPOs confirm this after a brief review of the privacy policy.

Is Kidoku Live compliant with COPPA for US schools?

Yes. COPPA compliance requires that no personal data is collected from children under 13 without parental consent. Kidoku Live collects no personal data from any user of any age. This design makes it compliant regardless of the age of the students using it.

Does deployment require IT department involvement?

No. Kidoku Live is a website, not an application. It requires no installation, no network configuration, no firewall changes, and no IT credentials. A teacher accesses it from any browser on any school device. The only IT consideration is whether kidoku.app is on the school's URL allowlist — it typically is, or can be added in minutes.

What is the cost model for schools?

Kidoku Live is free to play. There are no school subscription fees, no per-student licences, and no premium tiers required for classroom use. An optional Kidoku Plus upgrade exists for individual users but is never required for any classroom function. Schools can deploy and use it at zero cost indefinitely.

Can the head teacher set rules for how it's used in school?

The classroom mode includes teacher-controlled session settings: grid size selection, private room requirement, and session start/stop. There is no student account system to manage — students cannot create profiles or access the site outside of an active room session unless they have the URL. School ICT policy can restrict URL access at network level if required.

What does a typical DPO review of Kidoku Live look like?

Schools that have documented their DPO review typically cover: data collected (none), data stored (none), third-party sharing (none), chat/communication features (none), account creation (none). Most reviews conclude in under 15 minutes. Read our full Privacy & Safety policy for complete COPPA & GDPR compliance documentation.

GDPR-Safe EdTech for Schools — No-Data Classroom Sudoku

Head teachers evaluating educational technology face a standard set of questions from their DPO: what data is collected, where is it stored, and what is the consent process for students under 13. Kidoku Live answers all three questions before the conversation begins: no personal data is collected, no accounts exist to store data in, and no consent process is required because nothing about any individual is retained.

What Your Data Protection Officer Will Ask

The typical DPO checklist for classroom EdTech includes personal data collection, storage location, third-party data sharing, parental consent requirements, and COPPA/GDPR compliance. Kidoku Live passes each of these by design rather than policy: the platform does not request, store, or transmit any personal information about players. There is no data to breach.

IT Department Deployment — Zero Overhead

Kidoku Live requires no installation, no firewall exceptions, no SIS integration, and no staff onboarding. Teachers access it through a browser and students join with a six-character code. The school's IT department has no work to do. This is a meaningful differentiator from EdTech platforms that require months of procurement and deployment.

Curriculum Value That Justifies Board Approval

Kidoku Live is not purely recreational. Regular sudoku play develops the same constraint logic and systematic reasoning skills that underpin algebraic thinking, proof-writing, and problem-solving in mathematics. Schools that have adopted it as a structured activity report it as a measurable contribution to KS2 and KS3 reasoning outcomes.

Frequently Asked Questions

Is it COPPA and GDPR compliant?

By architecture: no personal data is collected from any player. There are no child profiles, no email addresses, no location data, and no behavioural tracking. Compliance is a consequence of how the system is built, not of a policy document.

Does it need parental consent for under-13 use?

No. Because no personal information is collected from students, GDPR and COPPA consent requirements for child data are not triggered. Students are identified only by auto-generated nicknames for the duration of their session.

Is Kidoku Live free?

Yes. The entire game — Quick Match, Grand Prix, private rooms, and all themes — is completely free to play. No subscription is needed to access any feature.

Does it require an account or sign-up?

No account is required. Players join with a 4-letter room code and are assigned a safe auto-generated username for the session. No personal information is collected.
