BBSTelnet

BBStelnet is a minimalist BBS terminal for Android — bring PTT, Bahamut, Hanachan and other classic BBS sites back to your pocket with familiar colors and the rhythm of typing one character at a time.

— Why BBStelnet —

Zero bloat. Zero tracking. The interface is just the terminal plus your site list and a floating side keyboard — every pixel is given back to the content itself.

— Full protocol support —

• Telnet (raw TCP) — works with PTT (ptt.cc) and most classic BBS hosts
• WebSocket (ws / wss) — for PTT WebSocket and modern proxies

Each site can be configured independently: default encoding (UTF-8 / BIG5), auto-login, anti-idle, URL detection.

— Bopomofo input with chain suggestions —

Built-in Bopomofo (Mandarin phonetic) IME with chain prediction — type 我 ("I") and it suggests 我愛你, 我們, 我想你. Runs entirely offline; nothing is uploaded.

— Custom quick keys —

The floating side keyboard holds your most-used commands, kaomoji, arrow keys, and Ctrl combos. 10 slots by default; expandable in +10 packs (with folder pages for free reordering).

— Multi-site management —

5 site slots by default. Expand with +5 packs; group by folder (sites sharing a name auto-group). Long-press to drag; swipe to switch pages.

— Immersive ambient sounds —

Upgrade to BBStelnet Pro to unlock 10 procedurally synthesized ambient soundscapes — deep rainfall, thunderstorm night, ocean waves, campfire, waterfall, fan white noise. Plays in the background, continues on lock screen.

— BBStelnet Pro (one-time purchase, permanent) —

• Remove all banner and interstitial ads
• Unlock 10 reading ambient soundscapes
• Unlock data export / import (sites, quick keys, settings, with optional password encryption)
• Encryption format is compatible with the iOS version — import/export both ways

— Expansion packs —

• Quick keys +10 / +20 / +30 slots (stackable)
• Site slots +5 / +10 / +15 slots (stackable)
• Restore purchases on the same Google account (Android entitlement cloud sync ensures consistency)

— Privacy first —

• Telnet / WebSocket connections go directly from your device to the BBS host. The developer cannot access and does not record any connection content.
• Site lists, quick keys, and settings are stored locally on the device.
• When you purchase Pro or expansion packs, only the IAP entitlement state (booleans and counters) is synced to Google Firebase for cross-device restore. No personal data is included.
• Third-party SDKs (Google AdMob / Play Billing / Firebase) handle data per their own policies — see Privacy Policy.

— Requirements —

Android 8.0 (API 26) or higher. Landscape main UI, portrait for input templates.
