Privacy Policy
Effective date: September 2, 2026
The short version: You can use Maestria without an account, and what you do stays on your device. An account (your email address) saves your study progress and syncs it across your devices, and you need one to subscribe so a purchase can be restored later. We collect only what the app needs to work — your email and your study statistics. We show no ads, use no third-party analytics or tracking, and never sell your data.
1. Who we are
Maestria ("we", "us") is a mobile application for Digital SAT Reading & Writing preparation, for iOS and Android. This policy explains what information the app handles, why, and the choices you have. Questions any time: support@maestriaprep.com.
2. Information we collect
Account information
You can use Maestria as a guest: no account, and nothing sent to us. Creating an account is optional for studying, and required only to subscribe, so your purchase and your progress can be restored on another device. If you do create one, we collect and store, using Supabase as our backend provider:
- Email address and password. Your password is stored only in hashed form; we cannot read it.
- Study statistics: XP, current and best streak, total questions answered, premium status, and last active date.
- Session history: for each completed quiz session, the module, difficulty, score, XP earned, and completion time.
- Diagnostic and score results: your study profile, your target score, your adaptive test results, and your score history.
- AI Tutor usage count: the number of tutor messages used against your daily allowance.
This data is protected by per-user access rules (row-level security): each account can read and write only its own records.
Data that stays on your device
Your detailed question progress, your mistakes notebook, vocabulary flashcard progress, daily goals, and settings are stored locally on your device; only the account records listed above sync to your account. If you use Maestria as a guest, all of it stays on the device and none of it reaches us. Deleting the app deletes this local data.
Purchases
Subscriptions are processed by Apple (App Store) or Google (Google Play). We never see or store your payment card details. We use RevenueCat, a subscription-management service, to validate purchase receipts and manage your premium entitlement. RevenueCat receives an anonymized app user identifier and purchase receipt information (product, price, purchase and renewal dates). See RevenueCat's privacy policy.
AI Tutor conversations (Premium)
When you use the AI Tutor, the messages you type — together with the question, answer choices, and passage you are asking about — are sent through our server to Google's Gemini API in order to generate the tutoring response. We use the paid tier of this service, under whose terms Google does not use these conversations to train or improve its products; content may be retained by Google for a limited period solely to detect abuse. We recommend not including personal information (names, contact details, and so on) in your tutor messages, as the tutor does not need it. See the Gemini API terms and Google's privacy policy.
Notifications
Daily practice reminders are local notifications scheduled on your device. They require your permission, involve no push-notification server, and send no data anywhere. You can disable them at any time in the app or in your device settings.
What we do not collect
- No advertising — the app contains no ads and no advertising SDKs.
- No third-party analytics or tracking SDKs.
- No location data, contacts, photos, or microphone access.
- We never sell your personal information, and we never share it for advertising purposes.
3. How we use information
We use the information described above solely to operate the app: to sync your progress across devices, to unlock premium features you have purchased, to generate AI Tutor responses when you request them, and to respond when you contact support. We do not use your data for profiling or marketing.
4. Service providers
| Provider | Purpose | Data involved |
|---|---|---|
| Supabase | Authentication and database for account sync | Email, hashed password, study statistics, session history |
| RevenueCat | Subscription validation and management | Anonymized user ID, purchase receipt data |
| Google (Gemini API) | Generating AI Tutor responses | Tutor messages and the related question content |
| Apple / Google | Payment processing, app distribution | Handled under their own terms and policies |
These providers process data on our behalf to deliver the features described and are not permitted to use it for their own advertising. Data may be processed on servers located outside your country, including in the United States and the European Union.
5. Data retention and deletion
Local data remains on your device until you delete the app. Account data is retained while your account is active.
You can delete your account yourself, at any time, from Delete Account in the app’s Profile tab. It is immediate: your profile, study statistics, session history and diagnostic and score results are removed from our systems there and then, and the subscription identifier held for you at RevenueCat is released. If you can no longer sign in, email support@maestriaprep.com from the address you registered with and we will delete it within 30 days. Either way, residual copies may persist in encrypted database backups for up to 30 days, after which they are overwritten automatically. Deleting your account does not cancel an active subscription — cancel that in your App Store or Google Play account settings. The full list of what is removed is at maestriaprep.com/delete/.
6. Your rights
Depending on where you live — including under the GDPR (European Union), the UK GDPR, the CCPA/CPRA (California), and the KVKK (Türkiye) — you may have the right to access, correct, delete, or receive a copy of your personal data, to object to or restrict certain processing, and to lodge a complaint with your local supervisory authority. To exercise any of these rights, contact support@maestriaprep.com. We will respond within the timeframe required by applicable law. We do not discriminate against you for exercising your rights.
7. Children's privacy
Maestria is intended for students preparing for the SAT and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has created an account, contact us at support@maestriaprep.com and we will delete it. Students under 18 should review this policy with a parent or guardian.
8. Security
All communication between the app and our servers uses encryption in transit (TLS). Account data is protected by row-level security so that each user can access only their own records. Authentication tokens are stored in your device's secure storage. No method of transmission or storage is 100% secure, but we work to protect your information using industry-standard measures.
9. Changes to this policy
If we make material changes to this policy, we will update the effective date above and, where appropriate, notify you in the app. Continued use of Maestria after changes take effect means you accept the updated policy.
