What's New
https://github.com/LeanBitLab/HeliboardL/compare/v3.6...v3.6.1/
Description
HeliboardL (Standard Version) is a fork of HeliBoard – a privacy-conscious and customizable open-source keyboard based on AOSP/OpenBoard.
This fork adds AI-powered features using the Gemini API while maintaining the original project's offline-first philosophy.
What's New in HeliboardL
- 🤖 Gemini AI Proofreading – Fix grammar and spelling with one tap (Standard only)
- 🌐 AI Translation – Translate selected text directly (Standard only)
- 🎨 Modern UI – "Squircle" key backgrounds and refined icons (incognito, etc.)
- 🕵️ Clear Incognito Mode – Distinct "Hat & Glasses" icon for better visibility
- 🔒 Privacy Choices – Choose between Standard (offline-first with opt-in AI) or Offline (network features hard-disabled) versions
- 📥 Gesture Library Downloader – Easier setup for glide typing
📦 Choose Your Version
We provide two distinct versions. Note: Both versions share the same package name (helium314.keyboardl) and signature, so only one can be installed at a time.
1. Standard Version
- Features: Full suite including AI Proofreading, AI Translation, and the Gesture Library Downloader.
- Permissions: Requests INTERNET permission (used only when you explicitly activate AI features or download libraries).
- Best For: Users who want smart features alongside strong privacy controls.
2. Offline Version
- Features: All UI/UX refinements (Squircle keys, new icons) but excludes all AI and network-related features.
- Permissions: NO INTERNET PERMISSION in the manifest. This is guaranteed at the OS level.
- Best For: Privacy purists who require a hard guarantee that no data can ever leave the device.

⚠️ Important
Privacy Notice: While HeliboardL itself is open-source and respects your privacy, using the free tier of the Google Gemini API means your input data may be used by Google to improve their models.
- Using AI features is optional.
- Do not process sensitive information (passwords, credit card numbers, private addresses) using the AI Proofreading or Translation features.
- The Offline Version completely removes this code and the associated permission.
