QuintaCapsa ("the app") is a flashcard app for learning words and phrases using spaced repetition, on the web and as an Android app. This page explains what data the app collects, why, and what your options are
Your cards and review history are stored only on your device - in your browser's local storage, or in the Android app's own storage. Nothing is sent to our servers, and we have no way to see or access this data. If you clear your browser data, uninstall the app or switch devices without signing in, it's gone - that's the tradeoff for not creating an account
We collect:
We use this only to provide the app's own features - syncing your cards, applying plan limits, and responding to feedback. We do not sell your data, and we do not use it for advertising or tracking. The app has no ads and no analytics
When you tap "Generate with AI", the front of that card, a few of your recent card backs (as a sample of your language and style) and your chosen card-back language are sent to Anthropic, which writes the back. Nothing else is sent, and only when you tap the button. Under Anthropic's commercial terms, this data isn't used to train their models
Daily review reminders are scheduled by the Android app on your phone itself - no server is involved, and the reminder only says how many cards are due, never what's on them. Reminder and vibration settings stay on the phone. The app downloads its own updates from Expo, which sees a standard request with the app's version and the type of device, like any download
On the website, Pro and donations are paid through Stripe. In the Android app, Pro and tips are paid through Google Play, and RevenueCat checks those purchases with Google and keeps track of the subscription, linked to an internal account number rather than your email. A tip works without an account and stays anonymous. We never see or store your card or payment details - Stripe and Google handle them directly
A few service providers process data on our behalf, strictly to run the app:
You can delete your account at any time from the Account screen, on the website or in the app. This permanently deletes your cards, review history, and account - on every device, not just the one you're using - and cannot be undone. Deleting the account doesn't cancel a subscription, so cancel it first. Step-by-step instructions are on our account deletion page. To request a copy of your data, or ask us anything else about this policy, contact us at support@quintacapsa.com
QuintaCapsa is not directed at children under 13, and we do not knowingly collect data from them
If this policy changes, we'll update the date at the top of this page
