Privacy Policy

Last Updated: [PUBLICATION DATE, e.g. October 20, 2026]

This policy covers NextGen AI Digital SAT Prep, made by DevApps AI, a trade name of ASEL ENTERPRISES Corp.

1. Information We Collect

You don't need an account to use the app, and it never asks for your name, email address or phone number. The app keeps your practice history, scores, goal score, test date and settings on your device.

Information leaves your device in the cases described in sections 4 to 8: when you use an AI feature, when the app loads practice questions or college logos, for advertising measurement, and when you subscribe through Apple.

2. How We Use Your Information

We use this information to:

• Provide the app's practice, AI and study features
• Track your learning progress and personalize study recommendations
• Protect our server from abuse
• Measure which of our ad campaigns lead to installs and subscriptions (section 6)
• Process subscriptions through Apple

3. Data Storage

Your practice history, scores, streaks, Mistake Notebook, flashcard progress, study plan, goal score, test date and settings are stored in the app's own storage on your device. Deleting the app removes them. Reset All Data in the app's Settings erases your study data and resets some settings. It keeps your other settings, today's use of the daily limits (so a reset does not refill them), a few records about this install, such as whether the app has already shown its tracking explanation and which advertising-measurement events it has already sent (section 6), and the Keychain records below.

Your AI Tutor and AI College Counselor conversations stay on your device while you use the app and are cleared the next time the app starts. The app does not save its other AI chats. College logos and pictures may be kept for a while in the app's cache by iOS, and a progress file you export is created in the app's temporary storage so you can share it; deleting the app removes both.

When you send an AI message, the app sends it, together with the earlier messages of that conversation, through our server to the AI provider (section 4). Our server passes it on without storing its content.

A few small records are kept in your device's Keychain, which iOS keeps even after the app is deleted and which are restored with an encrypted backup: when the app first ran on this device, a random purchase token (section 7), and the IDs of subscription charges already reported to Tenjin, so that reinstalling the app does not count the same purchase twice.

4. AI Services (Google and Anthropic)

The AI Tutor, the AI College Counselor, Scan & Solve and some new practice questions are powered by Google Gemini (Google LLC), with Anthropic Claude (Anthropic PBC) as a backup. When you use these features, the provider receives:

• your message and the earlier messages in that chat
• when you ask about a question you answered: the question and its passage, the answer choices, the answer you chose, the correct answer and whether you got it right
• when you ask about a question you're reviewing, also its explanation and, in the Mistake Notebook, how many times you missed it
• for a flashcard, the card and, in a quiz, its choices and the choice you picked
• in the College Counselor, a short study summary: your estimated SAT score and section ranges, your goal score, your number of practice sessions and how many colleges match
• in the College Counselor, for colleges you name, the app's College Scorecard figures for them
• in Scan & Solve, the photo you take

Before the AI Tutor, the College Counselor or Scan & Solve sends any of this for the first time, the app asks for your permission. Not now sends none of this, and practice questions, flashcards and tests work without it. You can turn this off any time in Settings (section 12).

The providers receive this from our server, not directly from your device, and we do not include your name, email address or a device identifier. Requests for new practice questions contain no personal information: only the subject, difficulty and topic, and short summaries of recently shown questions so they are not repeated.

How each provider may use and keep this data is set by the terms under which we use it: Google's Gemini API Additional Terms (ai.google.dev/gemini-api/terms) and Anthropic's Commercial Terms (anthropic.com/legal/commercial-terms).

5. Our Server and Your IP Address

When the app loads practice questions or uses an AI feature, it connects to our server, which runs on Cloudflare (Cloudflare, Inc.). As with any internet service, Cloudflare receives your device's IP address with each request.

To prevent abuse, our server keeps a request counter keyed by a one-way, keyed hash of your IP address, never the address itself, and deletes each counter after 24 hours without use. We also keep daily totals of AI requests, with no IP information, for 30 days. Our server passes AI requests through without storing their content. Requests for practice questions include the subject, the difficulty and the IDs of questions you have already seen, so they are not repeated.

6. Advertising Measurement (Tenjin)

We use Tenjin, a mobile measurement service, to learn which of our ad campaigns lead to app installs and subscriptions. Each time you open the app, the Tenjin software in the app connects to Tenjin. On a new install, the app shows a short explanation and then Apple's tracking question later in onboarding, after the diagnostic; if you allow tracking, the app connects to Tenjin again. Tenjin receives:

• an app-specific device identifier (IDFV)
• the advertising identifier (IDFA), only if you allow tracking when iOS asks
• an Apple Ads attribution token, so Tenjin can ask Apple whether an Apple Ads campaign led to the install
• device and app information such as device model, iOS version, app version, language and IP address; Tenjin works out your country from the IP address
• a few in-app events, when they happen: finishing onboarding, finishing your first practice session, viewing the subscription screen, and starting a free trial
• your subscription transactions: the start of a free trial, paid charges and renewals (plan, price, currency and Apple's transaction details)

Tenjin may also receive subscription status directly from Apple. Tenjin may tell the ad network that showed you our ad that the ad led to an install or a subscription, so the network can measure and improve our campaigns. The app also uses Apple's own ad attribution (SKAdNetwork), through which Apple can tell an ad network that an install or a subscription followed its ad without identifying you.

We do not show ads in the app. You can change your tracking choice at any time in Settings › Privacy & Security › Tracking. If you do not allow tracking, Tenjin does not receive the IDFA, but it still receives the other information above. Tenjin's privacy policy: tenjin.com/privacy.

7. Purchases Through Apple

Subscriptions are sold and billed by Apple through In-App Purchase. We never receive your payment details or your Apple Account details. Apple tells the app which subscription is active. The app attaches a random purchase token, created on your device, to each purchase, so that purchase records from Apple can be matched to this install. See apple.com/legal/privacy.

8. College Logos

College Match loads college logos and pictures directly from Wikipedia, DuckDuckGo, Google and the colleges' own websites. Like any website you visit, these sites receive your IP address, along with the name or web address of the college being shown.

9. Sharing

Apart from the advertising measurement described in section 6, we do not share your information with third parties for marketing or advertising purposes.

Google, Anthropic, Cloudflare and Tenjin receive information from the app only to provide their services to us, and they are bound by their terms with us to protect it at least as well as this policy describes. How long each of them keeps it is set by those terms: Google's Gemini API Additional Terms (ai.google.dev/gemini-api/terms), Anthropic's Commercial Terms (anthropic.com/legal/commercial-terms), Cloudflare's Data Processing Addendum (cloudflare.com/cloudflare-customer-dpa), and Tenjin's terms and privacy policy for its services (tenjin.com/terms and tenjin.com/privacy). Apple handles purchases under its own privacy policy (section 7). What our own server keeps, and for how long, is in section 5.

10. Age Requirement and Children's Privacy

The app is intended for students preparing for the SAT, typically 14 years of age and older. You must be at least 13 years old to use it, and if you are under 18, your parent or legal guardian must review and agree to our Terms of Use on your behalf. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe a child under 13 has used the app's AI features, please contact us at support@devappsai.com.

11. Data Security

Connections between the app and our server are encrypted (HTTPS). The app contains no AI service keys; our server adds them to each request. Data on your device is covered by your device's own security, such as its passcode. No method of sending or storing data is 100% secure.

12. Your Choices

• Tracking: change your choice at any time in Settings › Privacy & Security › Tracking.
• Camera and photos: allow or block access in Settings › Privacy & Security.
• Notifications: Settings › Notifications.
• Sharing with AI providers: the app's Settings › Progress & Data › Share questions with AI providers. Turned off, the AI Tutor, the College Counselor and Scan & Solve ask you again before they send your messages, answers or photos, and send nothing if you choose Not now. New practice questions are still requested; those requests contain no personal information (section 4).
• Your study data: Reset All Data in the app's Settings erases it, and deleting the app removes it; section 3 lists what each of them keeps. The Keychain records described in section 3 stay on the device.
• Subscriptions: cancel in Settings › your name › Subscriptions.
• Questions or requests about your data, including data that Tenjin holds for this app: contact support@devappsai.com.

13. Changes to This Policy

We may update this privacy policy from time to time. The date at the top shows the current version, and we will post any changes in the app and at devappsai.com/privacy.html.
