PRIVACY POLICY

Last updated May 18, 2026

This Privacy Notice for Langspool ("we," "us," or "our") describes how and why we might access, collect, store, use, and/or share ("process") your personal information when you use our services ("Services"), including when you visit our website at langspool.app, download and use Langspool, or engage with us in other related ways.

Langspool is a desktop software application for macOS that teaches vocabulary using spaced repetition. Users download the app and study language vocabulary locally on their device. The app uses an algorithm to schedule word reviews based on the user's performance. User study progress, mastery scores, and settings are stored exclusively on the user's local device and are never transmitted to our servers. The app offers a free tier of 100 vocabulary words and a one-time paid license (€19) that unlocks the full vocabulary set. Payments are processed by Lemon Squeezy, which acts as the Merchant of Record. We collect the user's email address if they voluntarily provide it for purchase confirmation or product updates. With explicit opt-in consent, we collect anonymous, aggregate usage analytics including session length, study frequency, and word rating patterns. No personally identifiable information is included in analytics data.

Questions or concerns? Reading this Privacy Notice will help you understand your privacy rights and choices. If you do not agree with our policies and practices, please do not use our Services. If you have questions or concerns, contact us at [email protected].
