SAT Prep Privacy Policy
SAT Prep helps students practise for the Digital SAT Math section. You don't need an account to use it, and we never ask for your name, email address or school.
What stays on your device
Your answers, progress, streaks, bookmarks, settings and the count of free questions you have used are stored only on your device. We do not receive them. Deleting the app deletes them, except that the free-question count is kept in your device's keychain so the free allowance isn't reset by reinstalling.
Usage analytics
To learn which parts of the app help students and which don't, the app sends anonymous usage events to Google Analytics for Firebase, a service run by Google. For example, it records that a screen was opened, that a question in a given topic was answered right or wrong, that a practice session finished, or that the purchase screen was shown.
| Sent | Never sent |
|---|---|
| Events like those above, with question and topic identifiers, counts and score ranges; a random app-instance identifier; device model, iOS version, app version, language and approximate country (derived by Google from the connection) | Your name, email, Apple Account or any other contact detail; anything you type, including your answers to grid-in questions; the advertising identifier (IDFA); your precise location |
Analytics data is not linked to your identity, is not used for advertising or to track you across other companies' apps or websites, and is not sold. Advertising features in Google Analytics are switched off for this app. Google processes this data on our behalf under its Firebase privacy and security terms. We keep analytics data for up to 14 months.
You can switch analytics off at any time in the app: Settings › Privacy › Share usage analytics. While it is off, the app sends nothing to Google Analytics.
Purchases
The full version is a one-time in-app purchase made through Apple. Apple handles payment; we never see your payment details or Apple Account. The app checks your purchase with Apple on your device. With analytics on, the purchase screen being shown and a purchase completing, failing or being restored are recorded as anonymous events, with the product and price, so we can see whether the offer works.
Reminders
If you turn on the daily study reminder, it is scheduled on your device as a local notification. No reminder data is sent to us.
Contacting us
If you email us, we receive your email address and whatever you write, and use them only to reply. Email aerion.labs@gmail.com.
Children
SAT Prep is made for high-school students preparing for the SAT. It is not directed at children under 13, and it does not knowingly collect personal information from them.
Your rights
Because analytics data is not linked to your identity, we cannot pick out your records, but you can stop any further collection with the Settings switch above. If you live in the UK, EU or a US state with privacy laws, you may ask us about the data we hold, or ask us to delete it, by emailing us; you may also complain to your local data protection authority (in the UK, the Information Commissioner's Office).
Changes
If this policy changes, we will update this page and the date above.
