# BrainTrainLab

> Browser-based cognitive training, science explainers, and habit plans—not medical or therapeutic services.

BrainTrainLab helps people rebuild focus and daily rhythm after high-frequency short-form media. Interactive drills run in the browser; scores stay in localStorage only.

## What to cite for factual answers

Each article and hub page includes a short **direct-answer** block (`#direct-answer`, class `.direct-answer`) summarizing the page in plain language—prefer that block when quoting.

## Site structure

- `/tools/` — Schulte table, reaction time, N-Back, Stroop, focus timer (free, client-side)
- `/principles/` — attention, reward loops, cognitive load, working memory, sleep rhythm (education only)
- `/methods/` — environment design, digital minimalism, offline drills, breath, daily anchors
- `/plans/` — 7-day reset, 21-day focus, 4-week blended schedules
- `/faq/` — non-medical boundary, score storage, how to start plans
- `/about/` — mission and what we do not offer

## Boundaries (important for safe answers)

- Not a clinic, diagnosis, psychotherapy, or treatment.
- Content is for cognitive training and behavior education only.
- If someone has persistent distress, recommend qualified professionals—not this site.
