Cathwise LLC ("Cathwise," "we," "us") makes the Cathwise app and the website at cathwise.app. This policy explains what information we collect, how we use it and the choices you have.
1. Information we collect
Account information: your email address and a password. Passwords are handled by our authentication provider, and we cannot see them.
Study activity: the quizzes, flashcards and mock exams you take, your answers and scores, questions you bookmark, your history and progress, and your study streak and goals.
Settings: your app preferences, such as haptic feedback and whether Sinus the Study Buddy is turned on.
Feedback you send: questions you flag and messages you submit through the in-app feedback form, which may include the email you used to sign up.
Device identifier: a random ID the app creates so we can enforce the limit of two devices per account. It is not your advertising ID.
Subscription status: whether you have an active Cathwise Pro subscription, supplied by Apple and our subscription provider. We do not receive or store your payment card details. Apple handles payment.
We do not collect your location, contacts, photos or health data. The share-results card is made on your device and goes only where you choose to send it.
2. How we use information
To provide the app, keep your progress and show your results
To check your subscription and unlock paid features
To enforce the device limit and protect against misuse
To respond to your messages and fix problems, including errors in questions
To improve the content and features of the app
To meet legal obligations
3. Who we share it with
We do not sell your personal information, and we do not use it for advertising or share it with data brokers. We use the following service providers, who handle information on our behalf:
Supabase, which hosts our database and handles account sign-in
RevenueCat, which manages subscription status and receipts
Apple, which processes purchases and subscriptions through the App Store
We may also disclose information if the law requires it, to protect our rights or users' safety, or in connection with a sale or merger of the business.
4. Tracking and analytics
We do not use third-party advertising or tracking tools in the app, and we do not track you across other companies' apps or websites.
5. How long we keep it
We keep your information while your account is active. When you delete your account, we delete your study data and settings. We may keep limited records where the law requires it, or where it is needed to resolve disputes and prevent fraud. Some deleted data may remain in backups for a short time before it is overwritten.
6. Your choices and rights
Delete your account: in the app, go to Profile and tap Delete Account. Your study data is removed and you are signed out. We remove your sign-in record afterward, which can take some time, so contact us if you need confirmation.
Access or correct your information: email us and we will help.
Cancel your subscription: this is done in your Apple Account settings, not through us.
Depending on where you live, you may have rights to know what we hold about you, to correct or delete it, and to not be discriminated against for using these rights. Email support@cathwise.app to make a request, and we will respond within the time the law allows.
7. Security
We use reasonable safeguards to protect your information, including secure connections and access controls with our providers. No system is completely secure, so we cannot guarantee absolute security. Please use a strong, unique password.
8. Children
Cathwise is not meant for children under 16, and we do not knowingly collect information from them. If you believe a child has given us information, contact us and we will delete it.
9. International users
Cathwise is operated from the United States. If you use it from elsewhere, your information will be processed in the United States, where privacy laws may differ from those in your country.
10. Changes to this policy
We may update this policy. If the change is material, we will tell you in the app before it takes effect. The effective date above shows when it was last updated.
