Privacy Policy

Last updated: May 2026

1. Overview

Recursio is a language-learning app that helps users save vocabulary, review words, practice grammar, and use AI-assisted learning features. This Privacy Policy explains what information Recursio may collect, how it is used, and how users can request deletion of their account and learning data.

2. Information We Collect

Account information: sign-in provider, account identifier, and email address if provided by Apple or Google.
Learning data: saved words, vocabulary spaces, word states, grammar progress, practice history, recall progress, Coach sessions, AI Writing attempts, and related learning activity.
AI practice content: text the user submits to Coach, AI Writing, AI Grammar, and similar learning features.
Subscription status: plan level such as PRACTICE, SMART, or PRO, entitlement status, and store-related subscription identifiers required to unlock paid features.
Technical data: app version, device/platform type, crash or diagnostic information if enabled later.

Recursio does not directly collect payment card details. Payments are processed by the App Store or Google Play.

3. How We Use Information

To provide saved vocabulary and learning progress.
To personalize recall, grammar, and Coach practice.
To generate AI feedback, explanations, and practice tasks.
To manage subscription access.
To improve reliability and fix technical issues.
To respond to support requests.

4. AI Processing

Some user-submitted text may be processed by AI service providers to generate feedback, corrections, explanations, practice prompts, or conversation responses.

Users should not submit sensitive personal information in practice answers.

AI feedback may be imperfect and should be treated as learning assistance, not as a guaranteed authoritative correction.

5. Purchases and Subscriptions

Subscription purchases are handled by Apple App Store or Google Play. Recursio receives subscription entitlement information needed to unlock paid features, but does not receive full payment card details.

6. Data Sharing

Recursio does not sell user personal data.

Data may be shared only with service providers needed to operate the app, such as authentication providers, hosting providers, AI processing providers, app store payment systems, or support tools.

7. Data Retention

Account-linked learning data is retained while the user account remains active, unless the user requests deletion or unless retention is required for legal, security, or operational reasons.

8. Account and Data Deletion

Users can request deletion of their account and account-linked learning data through the Delete Account page or by contacting support@recursio.app.

Deletion requests are processed within a reasonable period, typically within 30 days.

9. Children

Recursio is not intended for children under 13. If a parent or guardian believes a child has provided personal information, they should contact support.

10. International Users

Data may be processed in countries other than the user’s country of residence, depending on service providers.

11. Changes to This Policy

Recursio may update this Privacy Policy. The “Last updated” date will be changed when the policy is updated.
