About Open Lingo
A free, open-source language learning app built by learners. We fund hosting through optional ads—not by selling your data.
Our mission
Open Lingo helps people learn languages with spaced repetition, structured courses, and letter practice.
The project is open source. You can inspect the code, report issues, and contribute on GitHub.
How we’re funded
We aim to keep core learning free. Revenue may come from optional advertising (with your consent) and, in the future, optional premium subscriptions that remove ads and support development.
We do not sell personal information.
