How can
we help?

Sage Ape shows you English vocabulary inside real sentences. Each card hides one word — you read the sentence, recall the word, then swipe to reveal it. Swipe one way if you got it (CAUGHT!), the other way if you missed it (MISSED!). Cards you miss come back sooner.

All B1–B2 (intermediate) decks are free, no account needed. The premium subscription unlocks the C1–C2 decks — the higher-level vocabulary you need for fluent professional speech, exam prep, and nuanced reading.

Premium unlocks every C1–C2 deck and any future advanced content. It renews monthly until cancelled. Pricing is shown in the App Store or Google Play before you confirm — taxes vary by country.

Cancellation is handled by the store you subscribed through, not by Sage Ape. On iPhone: open the Settings app → tap your name at the top → Subscriptions → Sage Ape → Cancel Subscription. On Android: open Google Play → tap your profile picture → Payments & subscriptions → Subscriptions → Sage Ape. You keep premium access until the current billing period ends.

Sign in with the same Apple ID (or Google account, on Android) you used to subscribe, open Sage Ape, and tap Restore Purchases in the app. The store re-verifies your subscription and unlocks premium decks again.

Yes. Decks, cards, and your progress live entirely on your device. There is no account, no cloud sync, no analytics. You can use Sage Ape on a plane or in airplane mode without losing anything.

Because everything is stored locally, progress does not automatically sync across devices. If you switch phones, restoring your purchases will give you premium content on the new device, but card-level progress starts fresh.
