SATellar is an independent mobile application for practicing the Digital SAT. This Privacy Policy explains how the SATellar iOS application ("App") and our website at https://satellar.app (collectively, the "Service") handle your information.
SAT® is a registered trademark of College Board, which is not affiliated with, and does not endorse, SATellar.
For privacy questions, contact us at: [email protected]
When you first open SATellar, you enter a display name. That's the only thing you provide. We do not ask for, and do not collect, your email address, password, phone number, date of birth, or any other identifying information.
| Data Type | When Collected | Where It Lives |
|---|---|---|
| Display name | When you first open the App | Only on your device (local storage) |
As you practice, the App generates activity data. This data is stored only on your device (using local SQLite storage) and is never transmitted to us.
| Data Type | Description |
|---|---|
| Practice session data | Questions answered, answer selections, scores, time spent, session type |
| Performance data | Accuracy rates, difficulty level, subject-area performance, predicted score |
| Bookmarks | Questions you save for review |
| Badges & achievements | Earned based on your activity |
| Preferences | Theme (light/dark), notification settings, streak data |
If you purchase a subscription or a one-time session pack, the following limited information is processed by Apple and by RevenueCat (our subscription-management provider). See Section 4.2 for detail.
The App does not collect or transmit: email address, password, phone number, date of birth, precise location, approximate location, IP address (the App never contacts our servers), contacts, photos, microphone data, camera data, health data, crash reports with identifying information, or advertising identifiers.
Because practice data never leaves your device, we do not use it for anything — it is processed only by the App on your phone, on your behalf.
Purchase data (processed by Apple and RevenueCat, not us directly) is used only to:
We will never sell your personal information. We do not use your data for third-party advertising. We do not build advertising profiles based on your activity. We do not track you across apps or websites.
SATellar includes a leaderboard feature. Because practice data does not leave your device, no leaderboard data is shared between devices at this time. Your leaderboard standing is computed only from your own local activity. When friend-based leaderboards are introduced in a future version, this policy will be updated before that feature ships and only information you explicitly share (display name and overall score) would be transmitted, with your consent.
| Provider | Purpose | Data Shared |
|---|---|---|
| Apple | App Store payment processing | Apple ID, payment details (processed entirely by Apple; we do not see your payment card details) |
| RevenueCat | Subscription receipt validation, entitlement tracking, restore purchases | Anonymous App-user identifier, Apple purchase receipt, device platform/OS version, subscription status |
These providers process data on our behalf under contractual obligations of confidentiality. They do not receive your name, email, practice data, or any personally identifying information about you. See Apple's Privacy Policy and RevenueCat's Privacy Policy for how each of them handles data.
Because we do not collect or store your personal data on any server, there is typically nothing for us to disclose in response to legal requests. If a legal request is directed at Apple or RevenueCat regarding your purchase, those companies will respond according to their own policies.
If SATellar is involved in a merger, acquisition, or asset sale, information related to purchases (which lives with Apple and RevenueCat, not with us) may be transferred to the acquiring entity. Practice data remains on your device regardless.
We do not operate our own servers and we do not have a database that contains your practice activity or display name.
Purchase-related data handled by RevenueCat is stored on servers in the United States. For users in the EEA or UK, RevenueCat relies on Standard Contractual Clauses (SCCs) as the legal mechanism for such transfers; see RevenueCat's privacy policy for detail.
No method of transmission or storage is 100% secure. We cannot guarantee absolute security of data handled by Apple or RevenueCat on their own systems; please refer to their policies.
| Data Type | Retention Period |
|---|---|
| Practice data, display name, bookmarks, badges (local) | Stored on your device until you delete the App or reset its data |
| Apple purchase records | Retained by Apple per Apple's policies (typically required for tax and receipt-restoration purposes) |
| RevenueCat subscription records | Retained by RevenueCat per their policies (typically for the lifetime of your subscription plus legally required retention) |
Because your practice data never leaves your device, you have complete control over it at all times:
Under the California Consumer Privacy Act, as amended by the California Privacy Rights Act, California residents have the right to:
How to exercise your rights: Email [email protected]. We will respond within 45 days.
CCPA Disclosures (prior 12 months):
| Category | Collected by SATellar | Sold | Shared for Ads |
|---|---|---|---|
| Identifiers (display name you enter) | Yes — stored on device only | No | No |
| Internet/network activity | No | No | No |
| Education information (scores, sessions) | No — stored on device only | No | No |

If you are in the EEA or UK, the limited data processing that occurs (via Apple and RevenueCat during purchase) relies on the following legal bases:
| Legal Basis | Applies To |
|---|---|
| Performance of a contract (Art. 6(1)(b)) | Processing subscription purchases and delivering the paid features you purchased |
| Legitimate interests (Art. 6(1)(f)) | Fraud prevention and receipt validation (by Apple and RevenueCat) |
| Legal obligation (Art. 6(1)(c)) | Tax records (held by Apple per applicable law) |
You have the right to: access, rectification, erasure, restrict processing, data portability, object to processing, withdraw consent, and lodge a complaint with your local supervisory authority.
To exercise these rights, contact [email protected]. We will respond within one month.
In accordance with the California Online Privacy Protection Act: this policy is conspicuously linked from our App and website; we describe all categories of personal information collected and third parties with whom it is shared; and we honor "Do Not Track" browser signals by not engaging in cross-site tracking.
Residents of Virginia, Colorado, Connecticut, Utah, Texas, Oregon, Montana, and other states with privacy laws may have similar rights to those described in Section 7.2. To exercise them, contact [email protected].
SATellar does not require an account, and therefore we cannot enforce an age gate at registration. By using the App, you confirm that you are at least 13 years old. If you are a parent or guardian and believe a child under 13 is using SATellar, uninstall the App from the child's device to remove all local data immediately.
If you are a parent or guardian and you have concerns about your child's use of SATellar, contact us at [email protected]. Because all practice data lives on the device, uninstalling the App removes all data associated with use.
The SATellar mobile app does not use cookies. The App uses local device storage (SQLite and AsyncStorage) for app data and preferences.
Our website at https://satellar.app is a static marketing site. It does not set cookies, does not use advertising cookies, does not use third-party tracking pixels, and does not engage in cross-site tracking. We honor "Do Not Track" browser signals by design, because we do not track.
All payments are processed through the Apple App Store (iOS). We do not directly collect, process, or store your credit card or payment details. We receive only a transaction confirmation, purchase type, and subscription status via RevenueCat.
We use RevenueCat as a service provider to validate your purchase receipts with Apple, track your subscription tier, and support the "Restore Purchases" feature across reinstalls and new devices. RevenueCat receives only an anonymous user identifier, your platform purchase receipts, device platform/OS version, and subscription status. RevenueCat does not receive your name, email, or practice data. See Section 4.2 for details.
You manage and cancel subscriptions through your Apple ID settings (Settings → [your name] → Subscriptions → SATellar), or through the "Manage Subscription" link in the App. See our Terms of Service Section 5 for auto-renewal, cancellation, and refund information.
Because we do not operate servers that store your personal data, a data breach at SATellar affecting your personal information is extremely unlikely. In the event of any incident affecting information handled by RevenueCat or the App itself, we will:
We may update this policy to reflect changes in our practices or legal requirements. When we make changes:
