Installing outside the Play Store: enable "Install unknown apps" for your browser or file manager when prompted, then open the APK. It installs in place over any earlier BASTION build — your library, maps, and settings are kept.

What's in 1.0

• Library — import PDF, EPUB, and MOBI (open‑with, folder import, or linked in

place); read with highlights and bookmarks that persist; full‑text search.

• Maps — fully offline. Load your own map packs, drop and share waypoints, draw

annotations and layers. Ships with a built‑in base map.

• Tools — a customizable shelf of your field apps, organized into loadouts and

categories, with quick pins to the Emergency screen.

• Sync — SFTP, hosted HTTPS (ptgbastion.com), and device‑to‑device peer‑to‑peer.

Cherry‑pick exactly what you share. Enterprise units get per‑team roles and self‑provisioning share lanes.

• Emergency — a multi‑region blood chit (translated for EUCOM, AFRICOM, and

INDOPACOM) and one‑tap access to your pinned critical items.

• Security & EMCON — PIN and biometric lock, an encrypted (SQLCipher) database,

encrypted portable backups, and a network gate ("Go Dark") for emissions control. BASTION holds no INTERNET permission of its own — it only talks to a server you point it at, over a transport you choose.

Notes

• This is a stability milestone: no functional changes from 0.20.8 — the 0.x

series is now promoted to a released 1.0 line.

• Enterprise licensing is optional; core personal use is free.
