Terms

This installation of Kodukeel is provided by Upthink Solutions OÜ, registry code 16683946, at Aiandi tn 8/2-28, Mustamäe linnaosa, 12915 Tallinn, Harju maakond, Estonia. Reach them directly at privacy@upthink.ee. Estonian law asks a provider of an online service for exactly that: a name, a place, and a way to get hold of them quickly without going through a form.

It’s free and there’s nothing to buy, so the usual consumer purchase rules don’t apply: there’s no right of withdrawal and no payment terms. If an installation ever starts charging, that’s a different arrangement, and these terms don’t cover it. What it costs somebody to run, and who that is, is set out on the funding page.

Every Estonian word form here comes from Ekilex, the dictionary database run by the Institute of the Estonian Language. None of it is made up by AI. Where a form has been worked out by a fixed rule from one the dictionary stores, the screen says so.

Anu is a machine, and says so on every screen she speaks from. You are talking to a language model, not a teacher. Which model answered is printed under each reply.

She isn’t the final word on anything. She can explain grammar and suggest an English translation, but she can still get things wrong. Don’t rely on her for an exam answer without checking it yourself.

The app comes as it is, with no warranty. It’s a learning aid, not a certified language qualification.

Use one account, and use it yourself. Please don’t use the tutor for things that have nothing to do with learning Estonian. It runs on a key that costs money every time it’s used, so each account has a daily limit, to stop one person using it all up for everyone else.

Please don’t write scripts that hammer the dictionary, the speech service or the tutor with requests. Ekilex and TartuNLP are free academic services, and this whole project depends on nobody abusing them.

Be 13 or older, or have a parent agree first. Estonia sets the age at which somebody can agree to a service like this for themselves at 13, which is the youngest any country in the Union sets it. Nothing here checks. If you’re a teacher signing up a class, get that agreement before you send the link.

Your deck, your review history, your tasks and your notes are yours. Export them whenever you like from Settings, in a format that restores into any installation. The dictionary joins two sources with different licenses. Every Estonian form and every example sentence comes from Ekilex and is licensed CC BY 4.0 by the Institute of the Estonian Language. Every English gloss that was not written for this project comes from English Wiktionary and is licensed CC BY-SA 4.0 by its contributors, which is the stricter of the two: a work built on it has to be shared on the same terms. Both are credited on the sign-in page and in the footer.

The order the commonest words are listed in comes from FrequencyWords, a published count over the OpenSubtitles corpus, also licensed CC BY-SA 4.0. It decides nothing but an order: every word shown is the dictionary’s own.

Whether a spelling is an Estonian word at all, and which word it is a form of, is answered by a forms list built from Ekilex’s own inflection tables, as published in Estonian-Wordlist-Enriched-Ekilex (CC BY-SA 4.0), and from Vabamorf, Filosoft’s open-source morphological tools for Estonian (LGPL). That list decides whether a word is accepted and never what a card teaches: no form from it is ever drilled or marked against.

Hearing Estonian is done on your own device by TalTech’s streaming model, the Estonian speech model from Tallinn University of Technology (MIT), running in sherpa-onnx (Apache 2.0). The sound is never sent anywhere to be recognized. TalTech’s second model, which tells close sounds apart, is licensed CC BY-SA 4.0 and is not used yet.

You can stop and delete your data whenever you like. An installation may cut off an account that’s abusing the shared services described above.

Estonian law governs these terms and anything arising from them, and the Estonian courts are where a dispute ends up. Nothing here takes away a right you have as a consumer where you live: if the law of your own country gives you something these terms do not, that law wins.

If these terms change in a way that affects what happens to your data, the privacy page changes with them and both carry the date of the change.
