# Settings and Data

## Where everything lives

A `data/` folder is created **next to `OpsLog.exe`**:

- **Config** (SQLite): settings, profiles, rigs/antennas, cluster nodes, lookup
  cache, award lists, QSL templates. Always local, so the UI is instant.
- **Local logbook** (SQLite): QSOs, when the profile logs locally.
- `data/qsl/templates/…` — QSL card templates and their photos.
- `data/qsl/outbox/…` — sent QSL card JPEGs.
- Recordings folder (configurable) — per-QSO WAV/MP3.
- Backups.

Back up your setup by copying `data/` (and keep it with the exe). See
[[Profiles and Databases]] for local-vs-MySQL logbooks.

## Settings map

| Section | What |
|---------|------|
| **General** | language, theme, Main-view panes, live-status publish |
| **Station** | your callsign, grid, name, address (my-station ADIF) |
| **CAT** | radio backend + connection ([[CAT Control]]) |
| **Lookup** | QRZ.com / HamQTH credentials |
| **FlexRadio** | per-band RX/TX antennas |
| **Audio** | DVK / recorder devices, PTT, gains, RX monitor |
| **CW Keyer** | WinKeyer / Icom / TCI engine + macros |
| **External services** | LoTW (TQSL), QRZ, eQSL, ClubLog, HRDLog, POTA |
| **Email** | SMTP for eQSL-by-email |
| **PowerGenius / Antenna Genius / Rotator / Ultrabeam** | station hardware |
| **Backup** | database + ADIF backup at shutdown |

## Appearance & language

Four themes (Warm light, Warm dark, Graphite dark, High contrast) plus **Auto**
(follows the OS). Full **English / French** UI with a first-run flag chooser and
a switcher in Settings → General.

## Integrations (outbound UDP)

Push the current frequency to **PstRotator**, radio info in **N1MM `RadioInfo`**
format, or an **ADIF record on each logged QSO** — so external tools stay in sync.

## Other

- **Autostart** external programs (WSJT-X, JTAlert, rotator control…) at launch,
  skipping any already running.
- **Update check** at startup (toggleable).
- **Anonymous usage telemetry** — a once-a-day heartbeat (random install ID +
  version + OS; no callsign or QSO data). Opt out in Preferences.
