Information We Collect
Paratissimus keeps most of what it knows about you on your device, and you can use the whole app without an account.
If you create an account, our server stores your username and either a password (kept only as a one-way hash) or, with Sign in with Apple, the private identifier Apple assigns to you for this app and a token that lets us ask Apple to revoke that sign-in when you delete your account. If Apple shares your name, we keep it as your username.
While you are signed in, our server also stores your answer history — which question you answered, what you chose, whether it was correct, when, how long it took, and whether it was in a lesson, the practice exam, the mock exam or review — and your progress record (lessons completed with their scores and dates, points earned, streak, badges, your daily goal, the display name you set on Profile, and the app's own bookkeeping fields), so a new phone or a reinstall can pick up where you left off. As a guest, your answers and progress stay on your device until you sign in.
If you report a problem with a question, we store the report, the screen it came from and your username, or "anonymous" if you are a guest.
How We Use Your Data
To sign you in and restore your history and progress on your devices; to show you your own readiness and the questions you missed; and, combined across all users and never per person, to find questions that are unclear or wrong. Nothing about you is shown to other users. We do not sell personal data, and we do not use it for advertising.
Data Storage
On your device, progress and answers are kept in the app's storage, which is not encrypted; your session token is kept in the device keychain. On our server, account, answer and progress data are kept in a PostgreSQL database hosted by Railway in the United States. Account data, including answer history and progress, is kept until you delete the account. Our server and its host, Railway, see your device's network address when the app connects.
Third-Party Services
Apple processes subscription payments. RevenueCat manages subscription status and receives an account identifier (a random id, never your name or email) and purchase receipts; we never receive your card details. Sign in with Apple gives us a private identifier and, only if you allow it, your name. Expo delivers app updates: when the app checks for one, Expo receives a random installation identifier, your device's network address, which version of the app and its content you have, and, if the app failed to start on its previous launch, the error message. Reminders are notifications scheduled on your device; nothing is sent to us for them. We use no advertising or analytics networks.
Your Rights
You can see your own answer counts in the app (Profile). Start Over, in Settings, erases your progress and answers on the device and, if you are signed in, on our server. Delete Account (Settings → Account) removes your account and everything stored under it on our server, and asks Apple to revoke the Sign in with Apple grant if you used one. Purchase records stay with Apple and RevenueCat, and an Apple subscription is managed in your Apple ID settings; deleting the account does not cancel it. To ask about your data, write to support@hondosystems.com.
Children's Privacy

Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be reflected within the app and on paratissimus.com/privacy. Continued use of the app after changes constitutes acceptance of the updated policy.
