Privacy Policy

1. Information We Collect

We collect information you provide directly, information generated when you use Rew, and information processed by third-party services used in the app.

Account and profile information

• Name
• Email address
• Password, processed for authentication
• Future work or learning goal
• Avatar or profile image, if you upload one
• Email verification and account security information

Authentication and security information

• Access tokens and refresh tokens
• Session identifiers
• Session activity such as device/session records, last used time, and expiry time
• Basic technical data used to protect accounts and maintain sessions

Study and learning content

• Topics you create or generate
• Questions, answers, explanations, flashcards, and study materials
• Manual cards you create
• Files you choose to upload for study-card suggestions
• Answers you submit during study sessions
• Study progress, confidence ratings, scores, streaks, and usage limits

Companion chat information

• Companion profile choices
• Messages you send to the companion
• Companion responses and related conversation history

Rew uses your name, study and user content (including images you submit for study-card suggestions), study and product interaction data, study history, and companion choices to personalize greetings, study and review experiences, and companion responses.

Purchase information

• Product identifiers
• Google Play purchase tokens, signed StoreKit transaction information, or receipts
• Transaction identifiers, purchase status, and store environment when provided by Google Play or the Apple App Store
• Identifiers used to associate a purchase with the correct Rew account
• Subscription, premium, and credit entitlement status

Payments are processed by Google Play or by Apple through the App Store and StoreKit, depending on your platform. We do not receive your full payment card, bank account, or billing credential details.

Advertising information

Rew may show rewarded ads through Google Mobile Ads on Android and iOS. Google’s User Messaging Platform (UMP) is used to request and manage consent and privacy choices where required. On iOS, Rew may also show Apple’s App Tracking Transparency prompt before an advertising identifier is used for personalized advertising. If you do not allow tracking, you can continue using Rew and Google Mobile Ads can request ads without sending the Identifier for Advertisers (IDFA). Google and its advertising partners may process consent status, advertising identifiers, device information, IP address, ad interactions, diagnostics, and approximate location inferred from network information, depending on your device and platform settings, permissions, consent choices, and Google’s policies.

For server-side verification of rewarded ads, Rew sends Google Mobile Ads an opaque reward-session UUID and a random verification value. Neither value contains your Rew account ID, name, email address, or private study content. Rew links the reward session to your account on Rew’s systems only so it can verify the completed ad and grant the correct credit. This processing supports app functionality, including reward verification, and third-party advertising.

Device and technical information

Rew collects request and security metadata needed to operate and protect the service, including request identifiers, IP address, user agent when supplied, API route, status and latency, error and diagnostic details, and server logs. Rew uses this information for session and account security, rate limiting, fraud and abuse prevention, incident investigation, and service reliability and performance. Rew does not use this IP address to infer your location or for advertising or tracking.

Rew does not operate a first-party mobile crash-reporting SDK. Google Mobile Ads and its partners may process crash and diagnostic information as described in the Advertising information section above.

Rew does not request access to your contacts, precise location, microphone, phone calls, SMS, or government identification documents.

2. How We Use Information

We use information to:

• Create and manage your account
• Log you in and keep your session secure
• Verify your email address
• Generate study topics, cards, quizzes, explanations, and companion responses
• Save your study history and progress
• Check answers and provide feedback
• Provide usage limits, rewarded ad credits, purchases, subscriptions, and premium features
• Process and verify Google Play and Apple App Store purchases and entitlements
• Request and manage advertising consent and privacy choices where required
• Send account, verification, password reset, and security messages
• Prevent fraud, abuse, unauthorized access, and misuse
• Maintain, debug, secure, and improve Rew
• Comply with legal obligations

We do not sell your personal information.

3. AI Processing

Some Rew features use automated or AI-assisted processing to generate study materials, improve questions and answers, check submitted answers, and produce companion responses.

When you use these features, your prompts, study content, uploaded files, answers, and companion messages may be sent to our servers and service providers so the requested feature can work. Do not upload or enter information you do not want processed for these features.

We do not use your private study content for targeted advertising.

4. How We Share Information

We may share information with:

• Hosting, storage, database, and infrastructure providers
• AI and content-processing service providers
• Email delivery providers
• Google Play and the Apple App Store, including StoreKit, for billing, subscriptions, purchases, and entitlement verification
• Google Mobile Ads and Google’s User Messaging Platform for rewarded ads, consent, and privacy choices
• Security, fraud prevention, debugging, and operational service providers
• Legal authorities if required by law or to protect rights, safety, and security
• A successor organization if Rew is involved in a merger, acquisition, financing, or sale of assets

Service providers are only allowed to process data as needed to provide services to us, subject to their own legal and contractual obligations.

5. Data Storage and Security

We use reasonable technical and organizational safeguards to protect your information. Data is transmitted using secure network connections where supported. Authentication sessions stored on your device are protected using platform security features, including Android Keystore-backed encryption on Android and Apple Keychain on iOS.

No system can be guaranteed to be completely secure. You are responsible for keeping your account credentials confidential.

6. Data Retention

We keep personal information for as long as needed to provide Rew, maintain your account, comply with legal obligations, resolve disputes, enforce agreements, prevent abuse, and maintain security.

In general:

• Account and profile data are kept while your account is active.
• Study content, companion messages, and progress data are kept while your account is active unless deleted earlier.
• Purchase and entitlement records may be kept as needed for billing, accounting, fraud prevention, and legal compliance.
• Rew security and account audit logs are kept for no more than 90 days. Account deletion immediately removes request identifiers, IP addresses, user agents, and metadata from account-linked audit rows. Session records, including platform, IP address, and user agent, remain associated with your account until account deletion; expiry or revocation makes a session inactive.
• Backup copies may remain for a limited time before being deleted through normal backup cycles.

7. Account Deletion and Data Deletion

You may permanently delete your Rew account and associated account data in the app by opening Settings and selecting Delete Account.

If you cannot access the app, you may request deletion by visiting:

https://rewstudy.com/account-deletion.html

You may also contact us at support@rewstudy.com.

When we delete your account, we will delete or de-identify personal information associated with your account, except where we need to retain certain information for legal, security, fraud prevention, accounting, dispute resolution, or compliance purposes.

8. Your Choices and Rights

Depending on where you live, you may have rights to:

• Access your personal information
• Correct inaccurate information
• Request deletion of your information
• Object to or restrict certain processing
• Withdraw consent where processing is based on consent
• Request a copy of your information

To make a request, contact support@rewstudy.com.

You can also manage some information directly in the app, such as profile details, sessions, and account security settings.

When required by Google’s User Messaging Platform, Rew displays Privacy Choices in Settings so you can review or change your advertising consent choices. You can also manage applicable permissions and advertising preferences through your Android or Google settings and your iOS or Apple settings.

9. Children’s Privacy

Rew is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information to Rew, contact us and we will take appropriate action.

If you choose to make Rew available to younger users in the future, this Privacy Policy, the app’s Google Play target audience settings, and its App Store age rating must be updated.

10. International Processing

Your information may be processed in countries other than where you live. These countries may have different data protection laws. Where required, we use appropriate safeguards for international data transfers.

11. Third-Party Services

Rew uses third-party services that may process information under their own privacy policies, including:

• Google Play Billing
• Apple App Store and StoreKit
• Google Mobile Ads and Google’s User Messaging Platform
• Google services and Android platform services
• Apple and iOS platform services
• Hosting, infrastructure, email, security, and AI-processing providers
