# Memorea — Privacy Policy > Privacy policy for the Memorea English vocabulary app: learning data, optional account, analytics and notifications. - Página canónica: https://www.stellarflavor.com/memorea-privacy-policy - Sitio: Stellar Flavor (https://www.stellarflavor.com/) - Contacto: sun@stellarflavor.com --- **Last updated:** November 6, 2026 This Privacy Policy describes how Memorea ("the App", "we", "us", or "our"), developed by Stellar Flavor, collects, uses, and protects information when you use the App on iOS and Android. #### The short version Memorea works without an account. Your learning progress is stored on your device. An account is optional and only needed to back up your progress and use it on several devices. The App uses analytics to understand how it is used and to improve it, and it has no ads. #### Information We Collect - **Learning data stored on your device**: your progress with each word, your daily goal, level, streak, activity calendar and settings. This stays on your device unless you create an account, in which case it is backed up to your account (see below). - **Account information (optional)**: if you create an account, we receive your email address, your name if the service you use provides it, and the sign-in method you use. If you sign in with Google or Apple, we receive the name and email address that service shares with us (Apple may give you the option to hide your email). If you sign up with email and password, your password is handled by our authentication provider and is never visible to us. - **Progress backup (optional)**: when you are signed in, your progress, streak, activity and purchase status are saved in your account so you can restore them on another device. - **Usage and diagnostics data**: we use Firebase Analytics and PostHog to collect events about how the App is used (for example, which screens you open, when you start or finish a study session, and whether you view or complete the purchase), together with basic device and app information such as device model, operating system version, app version, language and approximate location derived from your IP address. If you are signed in, this data is linked to your account identifier. We also use PostHog session replay, which records how the App is used on screen to help us fix problems and improve the experience; text fields are masked and not recorded. - **Push notifications**: if you allow notifications, we use OneSignal to deliver them and to send occasional messages about your studying (for example, a streak reminder). OneSignal receives a device identifier and, if you are signed in, your account identifier, along with tags about your use of the App such as your daily goal. Daily reminders you set up in the App are scheduled locally on your device. You can turn notifications off at any time in your device settings. - **Purchase information**: the full-access unlock is a one-time purchase processed by Apple or Google. We never receive your payment details. The App checks your purchase status with the store. - **Support communications**: your email address and the content of any message you send us. We do not collect your precise location, contacts, photos or microphone audio. #### How We Use Your Information - Provide and maintain the App, including your study schedule and progress - Create and manage your account and your progress backup, if you use them - Unlock the full version and restore your purchase - Send reminders and notifications you have allowed - Understand how the App is used, fix errors and improve it - Respond to support requests - Comply with legal obligations We do not sell your personal information, and we do not use it for advertising. #### Sharing of Information Information may be shared with the following service providers, who process it on our behalf: - **Google Firebase** (Authentication, Cloud Firestore and Analytics), which hosts accounts and progress backups and provides analytics. - **PostHog** (servers in the European Union), which provides product analytics and session replay. - **OneSignal**, which delivers push notifications. - **Apple and Google**, to process purchases and, if you use it, sign-in with their services, under their own privacy policies. - **Legal authorities**, when required by law. - **Successors**, in connection with a merger, acquisition, or sale of assets. #### Data Retention and Deletion We keep your account and progress backup for as long as your account is active. You can delete your account at any time from the App: open the **Profile** tab, tap **Borrar mi cuenta** ("Delete my account") and confirm. This deletes your progress backup and your account, and clears your progress from the device. See our [account deletion instructions](/memorea-delete-account), which also explain how to ask us by email. Analytics and notification records are kept by the providers listed above under their own retention policies. To ask us to delete them as well, contact us using the details below. Data stored on your device is removed when you uninstall the App. #### Security We apply reasonable technical and organizational measures to protect your information, but no method of transmission or storage is completely secure. #### Your Rights Depending on your location, you may have the right to access, correct, delete, or export your personal information, to object to or restrict certain processing, and to withdraw consent. To exercise these rights, contact us using the details below. #### Children's Privacy The App is not directed to children under 13 (or the applicable age of digital consent in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us and we will delete it. #### Third-Party Services The App relies on third-party services, including Google Firebase, PostHog, OneSignal, Apple and Google, which have their own privacy policies. We are not responsible for their privacy practices. #### Changes to This Privacy Policy We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. #### Contact Us If you have any questions about this Privacy Policy, contact us at: **Email:** [sun@stellarflavor.com](mailto:sun@stellarflavor.com)
