# Barometer: Mood Journal App

Barometer is a private mood journal. You record your mood on a 1–5 scale together with the day's conditions, see a weather reference, and get a personal outlook only after enough records pass a check.

The app is built around a simple question: what was going on during the days that felt hard? You keep short records, look back at days with similar conditions and at the small actions you tried, and make your next choice with more of your own context. Barometer does not tell you what to do.

## Core concepts

- **Actual mood:** A 1–5 number you record for a date. It is stored separately from conditions, notes, and outlooks, and the app never turns a condition score, weather, or cycle date into a mood.
- **Conditions:** Things you choose to track, such as sleep, stress, and activity, or your own scale, yes-or-no, or numeric conditions. Numbers are the main record; units and scale labels are optional.
- **How the mood was known:** Each mood keeps its source: felt directly, heard from someone, observed, or unspecified. Outlooks only use records from the same source.
- **Weather reference:** When automatic weather is on for a location you chose, the app shows a 1–5 weather reference calculated from temperature, precipitation, and wind with a fixed rule. It is not a mood prediction and is never stored as a mood.
- **Outlook:** At first, an outlook is the average of your earlier mood records. A personal outlook appears only after enough comparable records exist and it beats simple baselines on your own past records. Outlooks stay separate from the mood you record.
- **Record books:** Each record book keeps its own conditions, moods, notes, actions, weather, cycle dates, consent, outlooks, and learning data. Linking two books only shows entries from the same date side by side.

## What Barometer is not

Outlooks, weather references, and action comparisons are reference information from your own records. They are not medical advice, proof of causation, or a guarantee of accuracy. The app does not infer another person's feelings, and recording a mood does not confirm anyone's inner state.

## Privacy and data

Records stay on your device by default and basic use needs no account. You can export a JSON backup (optionally password-encrypted) or a CSV ZIP for your own analysis. Optional cloud backup requires sign-in and is encrypted with your backup password before upload. Analytics stays off until you explicitly allow it.
