Question 1

Which languages does LingoKeep support?

Accepted Answer

Spanish and Japanese at launch, with the interface in English. We'd rather do two languages properly — dictionaries, phrase lookup, readings — than twenty badly. More languages will follow based on demand.

Question 2

Is spaced-repetition review really free?

Accepted Answer

Yes, permanently. FSRS review, dual subtitles, the dictionary, and sync are all part of the free plan. Review is the core of the learning loop, so putting it behind a paywall would defeat the point of the product.

Question 3

Why does the free plan cap the deck at 100 cards?

Accepted Answer

Storing and syncing cards costs us money, and 100 cards is enough to build a real review habit and see whether LingoKeep works for you. If you're saving more than that, you're getting real value from it — that's what Pro ($4.99/mo or $39/yr) is for.

Question 4

Does it work with auto-generated subtitles?

Accepted Answer

Yes. LingoKeep works with regular and auto-generated YouTube subtitle tracks. Auto-generated subtitles are less accurate than human-made ones — especially for fast or noisy speech — so dictionary lookups on them can occasionally miss.

Question 5

Does it work on Netflix?

Accepted Answer

Not yet. We're focused on doing YouTube really well first — it's free, has endless content in every language, and lets us link every flashcard back to the exact second of the video. Netflix support is on the radar for later.

Question 6

Can I export my cards to Anki?

Accepted Answer

Yes — Anki export (CSV, with AnkiConnect support planned) is a Pro perk. The export includes the word, sentence, translation, glosses, and a link back to the video moment, so your deck is never locked in.

Question 7

What data does LingoKeep collect?

Accepted Answer

Your account email and the cards you explicitly save — that's it. We don't track your browsing or watch history. The extension's permissions are limited to youtube.com and lingokeep.com, and you can delete your cards or your account anytime.

Question 8

What's your refund policy?

Accepted Answer

If Pro isn't working out, email us within 14 days of a charge and we'll refund it, no questions asked. You can also cancel anytime from your account page and keep Pro until the end of the paid period.
