Teachers don't need more data. They need clarity.

The problem isn't effort. It's arithmetic.

Teachers already do an extraordinary amount of work, and almost all of them can tell you which students are struggling. What no one can do by hand is work out why — at the concept level, for thirty students at once, every week.

That is not a workload that can be solved by working harder. It is more information than a person can hold — which is exactly the kind of problem software should be taking off a teacher's hands.

And the cost of not doing it is specific. When the analysis can't be done, the response defaults to re-teaching the topic where the mistake appeared. For a student whose real problem is a foundational gap two years upstream, that intervention is effortful, well-intentioned and almost entirely wasted.

What Sublogy does for a class

Sublogy gives every student practice matched to what they have already mastered, with a worked example behind every question and a study assistant when they get stuck. Underneath, CUBALE reads every response as evidence about concepts, traces weak concepts down to the earliest idea that isn't secure, and adapts each student's practice accordingly.

What reaches the teacher is not thirty dashboards. It is the short list of things worth acting on.

The point is triage. A teacher with thirty students and one free period does not need more data; they need to know which three students and which one concept to spend it on.

What teachers get

One thing Sublogy deliberately does not do is decide for the teacher. CUBALE identifies patterns and detects likely gaps; it recommends areas for reinforcement. What to do about a particular child is a teaching judgement, and the person in the room can see things the data cannot.

What students get

• Work at the right level. Questions are chosen to match what the student has already mastered, so the work stays hard enough to be interesting and easy enough to finish.
• A worked example behind every question. Not just the answer, but the steps, written the way a teacher would explain them.
• Help when they're stuck, from a study assistant kept to the lesson in front of it and built to help them understand rather than hand over answers.
• Visible progress. Belts, White through to Black, so effort turns into something a student can see.
• The foundation fixed, not the symptom. If the real gap is two years upstream, that's what they get to work on.

Coverage: classes 6 to 10 — Mathematics, Science, English Grammar, Vocabulary, Reading Skill, Spoken and Written Expression, and Reasoning, plus Maths, Science and English Olympiad preparation.

How a school rollout works

1. The school creates the accountsThere is no sign-up inside the app. The school provides the information needed to create accounts and decides who is authorised to use the service, and for how long.
2. Students sign in with a school-issued usernameSublogy runs as a web application and as iOS and Android apps, so it works in a computer lab, on a shared tablet, or on a phone at home.
3. Teachers are mapped to their classesA teacher sees the progress of students in their own classes — not the whole school.
4. Students practise; CUBALE builds the pictureThe concept-level view fills in as evidence accumulates. It gets more useful the more a class uses it, because a concept is judged on patterns rather than single answers.
5. Teachers act on the short listConcepts needing attention, students affected, and where a period of teacher time is likely to be worth most.
6. Accounts end when the school says soAn account lasts as long as the school's subscription. When a school ends its subscription, or asks us to remove a student, that student's personal data is deleted within 90 days.

Data, privacy and safeguarding

Sublogy is used by children, and the product is restrained accordingly. This is the section worth forwarding to whoever signs off on software in your school.

• No advertising of any kind, and no advertising software in the app.
• No behavioural tracking or profiling. No analytics tools following students across other apps or websites.
• No selling or renting of personal data — to anyone, for any purpose.
• No in-app purchases, and no payment details collected in the app.
• No social logins or sharing features, and no student-to-student messaging.
• Minimal collection. Name, class, school and username; answers, scores, time taken and progress; and basic technical records. No phone number, home address, photograph, date of birth or location. The app does not use the camera, microphone, contacts or location, and never asks permission to.
• Data is stored in India, encrypted in transit and at rest.
• The AI assistant is constrained. Sublogy Buddy is restricted to the lesson being studied, its replies are screened for material unsuitable for children before they are shown, nothing identifying the student is sent with a question, conversations are not stored on our servers, and our agreement with the AI provider does not permit Sublogy data to be used to train its models.
• The school stays in control. Schools create and manage accounts and can ask us at any time to show, correct or delete a student's data.

The complete detail is in the privacy policy. There is more on how the AI is used, and where its limits are, on AI-powered learning.
