Privacy Policy

1. Overview

GramLingo is an English grammar and vocabulary learning app. We are committed to protecting your privacy and handling your data transparently. This policy explains what we collect, why, and how you can control it.

2. What We Collect

GramLingo collects only the minimum information needed to run the service:

• Account information — if you create an account, your email address and a password (stored as a secure hash).
• Learning progress — your completed lessons, scores, and the questions you answered incorrectly, so the app can save your place and personalize practice.
• App preferences — your selected display language and interface settings.

We do not collect your name, location, contacts, device identifiers, or browsing history, and we do not show third-party advertising.

3. How We Use Your Data

• To create and authenticate your account.
• To save and sync your learning progress across sessions and devices.
• To personalize your learning experience.
• To respond to support requests.

4. Data Storage & Security

Account credentials and cloud-synced progress are stored with Supabase, an industry-standard hosted database service, which uses encryption in transit and at rest. If you use the app without creating an account, your progress is stored only on your device.

We apply reasonable technical safeguards to protect your data. No method of transmission or storage is 100% secure, but we work to keep your information safe.

5. Data Sharing

We do not sell, rent, or share your personal data with third parties for marketing. We may share limited data with service providers strictly as needed to operate the app (for example, our database host), and only under confidentiality obligations.

6. Children’s Privacy

GramLingo is intended for general audiences. We do not knowingly collect personal information from children under 13. If you believe a child has provided us personal information, contact us and we will delete it.

7. Your Rights

You may request access to, correction of, or deletion of your personal data at any time by contacting us. You may also delete your account, which removes your cloud-stored data.

8. Changes to This Policy

We may update this policy from time to time. Material changes will be reflected by updating the “Last updated” date above and, where appropriate, notified within the app.
