About LinguaForge

LinguaForge is a private language learning companion that runs entirely on your device. Practice grammar, expand vocabulary, and polish your writing without sending data to the cloud. Your study sessions remain 100% offline, ensuring total privacy for your personal language practice. Use the five distinct refinement modes to correct errors, enhance vocabulary, improve fluency, simplify complex texts, or adjust contextual tone. Save your refined sentences to a local library for future review. Search your saved entries instantly. Choose from multiple themes to suit your environment. Designed for learners who value data sovereignty, LinguaForge keeps your linguistic journey strictly within your control. This app installs at no charge. Its features are unlocked by the in-app purchase: a Pro subscription (EUR 2.99/month, renews automatically until cancelled, cancel anytime in Microsoft Store settings) or a one-time Lifetime purchase. There is no trial period, and nothing is charged automatically.

How the subscription works

free + Pro EUR 2.99/mo

• Auto-renews monthly via Apple's standard subscription system.
• Cancel anytime in Settings → Apple ID → Subscriptions.
• Refunds are handled by the store that took the payment, under its own policy: Apple at reportaproblem.apple.com, Google Play and the Microsoft Store through your account with them.
• No third-party tracking or analytics SDKs inside the app.

What we don't collect

• Your contact list, photos, location, microphone, or camera.
• Any content you enter into the app (notes, logs, data) — it stays on your device unless you explicitly sync.
