Privacy Policy

Effective November 13, 2026

This policy covers the Retainify app and retainifyapp.com, operated by Victor Espinoza. Retainify helps readers review books through recaps, quizzes, quotes, and vocabulary practice.

Information we collect

• Account and profile. When you sign in, we receive an account identifier, email address where provided, and profile details you choose to share, such as your name or photo. If you use Apple or Google sign-in, the provider controls which details you share.
• Reading and learning activity. We store the books you save or request, your saved quotes and vocabulary, quiz progress and results, completed activities, and reading streaks. Book search queries are sent to our search provider to return results.
• Purchases. We receive subscription and transaction information, such as your entitlement and whether a subscription is active, to provide paid features and restore purchases. Apple handles payment details for App Store purchases.
• Diagnostics and messages. The app sends crash reports and may associate them with your account identifier to help diagnose issues. If you contact us, we receive the information you include in your message.
• Website requests. When you visit the site, Cloudflare processes technical request information such as your IP address and browser details to deliver and protect the site. The current landing page has no sign-up form or advertising scripts.

How we use and share information

We use information to operate accounts, sync reading progress, deliver search results, manage subscriptions, troubleshoot errors, respond to requests, and protect the service. Providers supporting these functions include Google Firebase for authentication, storage and crash reporting, Algolia for book search, RevenueCat for subscription management, Apple for App Store purchases and Apple sign-in, and Cloudflare for website hosting. We may disclose information where the law requires it or to protect users or the service.

Retention and account deletion

We keep account and reading information while your account is active and as needed to provide the service. We may retain limited records as necessary to meet legal obligations, resolve disputes, or protect the service. To start deleting an account, use Delete Account in the app’s settings. For help with an account or data that remains after deletion, contact us. If you have an App Store subscription, manage or cancel it separately in your Apple account settings.

Your choices and rights

You can contact us to request access, correction, or deletion of your personal information, or to withdraw consent where processing relies on it. Available rights depend on where you live. We may verify your identity before acting on a request.

Children and changes to this policy

Retainify is intended for a general audience. If you believe a child has provided personal information in circumstances that require parental consent, contact us so we can review it. We will post revisions here with an updated effective date and provide additional notice where required.
