## What LifeByLogic is

LifeByLogic is not a blog or article archive. It is a publication of interactive tools — instruments people use to assess, model, and reflect on decisions. Each tool is grounded in peer-reviewed research, transparent in its methodology, and operates entirely client-side (no server-side data collection beyond standard analytics).

The publication is organized into four laboratories:

- **[Brain Lab](https://lifebylogic.com/brain-lab/):** Tools for cognitive performance, sleep, memory, and mental health, built on peer-reviewed neuroscience.
- **[Crossroads Lab](https://lifebylogic.com/crossroads-lab/):** Decision-support instruments for major life-direction choices.
- **[Behavior Lab](https://lifebylogic.com/behavior-lab/):** Tools built on cognitive psychology and behavioral economics — catch your mind in the act.
- **[Life Dashboard](https://lifebylogic.com/life-dashboard/):** Personal analytics and longitudinal flourishing measurement.

## Editorial principles

Three principles bind every LifeByLogic tool:

1. **Peer-reviewed sources only.** Every tool's underlying methodology traces to citable academic literature. Citations appear inline; methodology is documented separately.
2. **Your data stays yours.** All tools operate client-side. We do not transmit individual responses to our servers. Aggregate analytics are anonymous.
3. **Descriptive, not prescriptive.** Tools model patterns and outcomes; they do not prescribe choices.

## LifeGraph+ (optional personal tracking)

[LifeGraph+](https://lifebylogic.com/lifegraph/) is an optional, account-based layer that lets people save results from LifeByLogic assessments into one evolving profile. It adds a multi-axis trait map across seven life domains, longitudinal tracking as assessments are retaken, a daily Life Pulse check-in, and a cross-domain synthesis that reads results together (a Plus feature at $4.99/month; the profile, trait map, tracking, and Life Pulse are free). Unlike the standalone client-side tools, LifeGraph+ stores saved results server-side in encrypted form; it is opt-in, contains no ads, and data is exportable and deletable on demand.
