Mondly: cost, fit and limits
Mondly is an online language learning app made by ATI Studios A.P.P.S. S.R.L., part of the Pearson group, that offers a free version and a Premium tier for self-study learners, with machine learning systems named in its terms.
What to know first
Mondly describes itself as an online language learning platform developed by ATI Studios SRL and owned within the Pearson group. The vendor FAQ names a free version and Premium. The pricing page could not be opened during our check, so plan prices are not stated here. The terms say the service may use machine learning and large language model systems, and a separate technologies page is referenced.

Who Mondly is best for
Beginners starting a new language
The free version lets a newcomer sample the lessons first, and the vendor positions the app as a self-study start rather than a course with a teacher or a deadline.
Learners comparing several apps
Because a free version is named on the vendor FAQ, Mondly can be tried alongside a paid app without a commitment, which helps when you cannot yet tell which lesson style suits you.
Buyers in the EU
The privacy policy names ATI Studios SRL as controller and Pearson Deutschland GmbH in Frankfurt as EU representative, so there is a named contact for data requests.

What Mondly does
- Self-study app
- The vendor calls Mondly an online language learning platform. The pages we opened describe it in general terms and do not list a lesson catalog, so the course structure is unverified.
- Machine learning in the service
- The terms say Mondly may use machine learning and large language model systems in its Services. The FAQ points to a separate page on technologies used, which we did not capture.
- Pearson group ownership
- The about page places Mondly inside the Pearson group, which matters for who sees account data, since the privacy policy lists several Pearson companies as recipients.
- Account and profile data
- The privacy policy covers registration, profile and transaction data, so a paid account carries a transaction record that stays with the vendor for legal and tax reasons.
How Mondly handles your data
The privacy policy says registration, profile and transaction data are kept while the account is active. After deletion, data not needed for legal, tax, accounting or regulatory purposes is removed, and the rest is kept for 6 years from collection. The vendor states it does not sell personal data. ATI Studios SRL is the controller, with Pearson Deutschland GmbH in Frankfurt as EU representative. Data is shared with Pearson group companies. The policy contains no statement on training AI models with user content.
Where Mondly falls short in practice
- Prices could not be checked. Pricing returned HTTP 403 and 404 during our check, so we cannot say what Premium costs or how it bills. Check the live pricing page before you plan a budget.
- AI features are vague. The only AI wording we found sits in the terms. Nothing we read describes a speaking partner, feedback model or lesson generator, so do not assume conversation practice from the terms alone.
- Six-year retention after deletion. Data kept for legal and tax reasons is held for 6 years from collection, which is long for a casual learner who expects deletion to remove everything.

Mondly: common questions
Does Mondly have a free version?
Yes. The vendor FAQ names a free version alongside Premium. We could not open the pricing page, so the exact limits of the free version and the Premium price are not confirmed here. Check the live site for the current split.
Who owns Mondly?
The vendor about page says Mondly is developed by ATI Studios SRL and is part of the Pearson group. The legal name in the terms is ATI Studios A.P.P.S. S.R.L., which is also the maker named in our listing. Its legal entity sits outside the Pearson brand name, so data requests go to the controller named in the privacy policy.
Does Mondly use AI?
The terms say Mondly may use machine learning and large language model systems in its Services, and the FAQ points to a page on technologies used. We did not capture that page, so we cannot name specific AI features such as a conversation partner.
Does Mondly train AI models on my lessons?
The privacy policy we read contains no statement about training AI models on user content. That is an absence of wording, not a promise, so ask the vendor directly if this matters for your use. The same policy says the vendor does not sell personal data, but that line is separate from any training question.
How long does Mondly keep my data after I delete my account?
Data not required for legal, tax, accounting or regulatory purposes is deleted. The remaining data is kept for 6 years from collection, according to the vendor privacy policy, and may be shared with Pearson group companies. The policy lists Pearson Education Limited among the recipients of shared data.
