# LipiFlow > LipiFlow is an AI-powered keyboard for Android by Dev Pixels Studio LLC. It fixes grammar, rewrites tone, and translates text as you type — natively supporting English and Hinglish (romanized Hindi), plus 20+ languages for translation. AI runs only on explicit user action; everyday typing stays on-device. ## What LipiFlow does - **Grammar Fix (✨):** One-tap correction of typos, grammar, and punctuation. Context-aware — it reconstructs what the user meant ("let go party night today" → "Let's go to the party tonight."). - **Tone:** Rewrites a message in 14 tones (professional, friendly, casual, polite, funny, romantic, confident, and more) while keeping the user's language. - **Fix & Translate:** Fixes grammar first, then translates into 20+ languages (Hindi, Spanish, French, German, Japanese, Arabic, Bengali, Tamil, and more). - **Hinglish-native:** Fixes code-mixed Hinglish text while keeping it in Latin script — never force-converts to Devanagari, never translates unless asked. - **Full keyboard:** gesture typing, adaptive autocorrect, next-word/phrase prediction, emoji, GIF search, stickers, clipboard suggestions, voice typing, themes, one-handed mode. ## Privacy model - Everyday typing, suggestions, and the personal dictionary run entirely on-device and are never transmitted. - Text is sent to the cloud only when the user explicitly taps an AI button, and only the selected text. Processing is done by OpenAI via a secure backend proxy (Supabase); request text is not stored by LipiFlow and is not used to train models. - Password/secure fields are always excluded from every feature. - Account deletion is self-service, in-app. ## Platform and pricing - Android (Google Play). iOS is on the roadmap. - Free: full keyboard + a monthly AI allowance. LipiFlow Pro subscription: unlimited AI (priced in-app via Google Play Billing). ## Pages - [Home](https://lipiflow.app/): product overview, features, FAQ - [Privacy Policy](https://lipiflow.app/privacy): full data practices, subprocessors (OpenAI, Supabase, Google, RevenueCat), retention, deletion - [Terms of Service](https://lipiflow.app/terms): license, subscriptions, acceptable use - [Contact](https://lipiflow.app/contact): support@lipiflow.app, +1 (307) 785-6988, Dev Pixels Studio LLC, 312 W 2nd St Unit #A2733, Casper, WY 82601, USA ## Company Dev Pixels Studio LLC — Wyoming, United States.
