Privacy Policy
Effective Date: May 29, 2026
Provided by Moonslide Inc.
Scope of This Policy
This Privacy Policy applies to the consumer version of WordFlow — the version individuals use to learn vocabulary on their own, with billing handled through the App Store, Google Play Store, or Stripe.
If you are a school, district, teacher, or student using WordFlow through an agreement with your school or district, this policy does not apply to you. Your use of WordFlow is governed by our separate school privacy policy, which is designed to comply with FERPA, COPPA, and applicable state student-privacy laws. Please visit the WordFlow School Privacy Policy instead.
1. Introduction
Thank you for choosing WordFlow. Your trust matters to us. This Privacy Policy explains how Moonslide Inc. collects, uses, discloses, and safeguards your personal information when you use the consumer version of WordFlow (the "Service"). By using the Service, you agree to the collection, use, and sharing of your personal information as described here.
2. Information We Collect
  • Personal Data: We collect your name, general location, and email address for customer support, billing, and service delivery.
  • Email Communications: When you register and agree to our Terms of Service and this Privacy Policy, you are subscribed to our newsletter and promotional emails. You can opt out at any time using the unsubscribe link in any email or by contacting us directly.
  • App Usage: We track which books you read, the words you study, how often you log in, and similar usage information so we can deliver a personalized learning experience.
  • IP Address: We collect your IP address for security and to infer your general location for analytics.
3. How We Use Your Information
  • Service Delivery and Improvement: To run WordFlow, personalize your learning, conduct research, perform analytics, and inform our marketing.
  • Billing and Payments: To manage your payments through Stripe or through Apple/Google when you subscribe via their stores.
4. Third-Party Access
  • Stripe: WordFlow uses Stripe for payments made outside the App Store or Google Play Store. Moonslide Inc. does not store or access credit card information. We link the Stripe customer account to your user ID for billing purposes only.
  • Apple App Store and Google Play Store: When you subscribe through one of these stores, your payment is handled entirely by Apple or Google under their own privacy policies.
  • Analytics Platforms: We share basic, mostly aggregated usage data with analytics providers to understand how the Service is used and how to improve it.
5. Cookies and Tracking
We use cookies for login and session management. We may also use cookies to measure the effectiveness of our marketing.
6. Data Storage and Security
Moonslide Inc. does not store credit card or payment data. User data is hosted by cloud providers including Amazon Web Services and DigitalOcean. We follow NIST standards to secure our data.
7. Your Rights
To access, correct, export, or delete your personal data, email us at [email protected]. Depending on where you live, you may have additional rights under laws such as the GDPR or CCPA, including the right to object to or restrict certain processing.
8. Children's Privacy
The consumer version of WordFlow is not directed to children under 13 and is not intended for their use. We do not knowingly collect personal information from children under 13 through the consumer Service. If we learn that we have collected such information, we will delete it promptly.
Children under 13 should only use WordFlow through a school or district that has entered into a school agreement with Moonslide Inc., which provides the parental-consent and FERPA/COPPA protections required for educational use. See the School Privacy Policy.
9. International Users
The Service is available to users inside and outside the United States. Your information may be transferred to and processed in the United States. We work to comply with applicable laws including the GDPR and CCPA.
10. Data Breach Protocols
In the event of a data breach affecting your personal information, Moonslide Inc. will notify affected users within the timeframe required by applicable law and will describe what was affected and what we are doing in response. We limit the personal data we collect to reduce exposure.
11. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. If we make material changes, we will notify users through WordFlow or by email and update the "Last Revised" date above.
