This Privacy Policy describes how Helium Edu ("Helium," "we," "us," or "our") collects, uses, and shares information when you use our website, mobile applications, and related services (collectively, the "Services").

Your use of the Services is also governed by our Terms of Service.

1. Information We Collect

Information You Provide: Account information (such as username, email, and password), optional phone number (for SMS reminders), time zone, planner content (such as classes, assignments, grades, events, notes, reminders, and attachments), and external calendar URLs you choose to import.

Information Collected Automatically: Device and app information, push-notification device tokens/identifiers, usage analytics, and crash/error reports used to troubleshoot and improve the Services.

Third-Party Login: If you sign in with Google or Apple, we receive your verified email address and a provider identifier needed to authenticate your account. We do not receive your third-party password.

2. How We Use Your Information

We use your information to provide and maintain the Services, authenticate users, sync and display planner/calendar data, send reminders (push, email, or SMS when enabled), support import/export and private feed features, improve performance and reliability, and comply with legal obligations.

3. Information Sharing

We do not sell your personal information. We share information only with:

• Service providers who help us operate the Services (for example, cloud hosting, authentication, analytics, messaging, and error monitoring)
• Legal authorities when required by law or to protect rights, safety, and security
• Business transfers if we are involved in a merger, acquisition, financing, or sale of assets
• Authorized personnel who may access account data on a need-to-know basis for purposes of operating and maintaining the Services, providing customer support, or as required by law

When you enable private calendar feeds, your calendar data becomes accessible to anyone with the unique feed URL. Treat these URLs as confidential.

4. Data Storage and Security

Your data is stored and processed on servers in the United States. We use reasonable technical and organizational safeguards to protect personal information, but no method of transmission or storage is completely secure.

5. Data Retention

We retain account data while your account is active. Accounts that are not verified are automatically deleted after a limited period (currently 7 days). If you delete your account, associated account data is removed within 30 days. Accounts that have been inactive for two (2) years may be deleted after advance notice by email. We will attempt to notify you at the email address on file before any such deletion.

6. Your Rights and Choices

You may access, export, or delete your data through the Services. You can disable push notifications in your device settings and manage optional communications using available in-product settings or unsubscribe links.

7. Cookies and Local Storage

We use cookies and similar local storage technologies for security, authentication, preferences, and analytics. Some are required for core functionality.

8. Children's Privacy

Helium is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe we have collected such information, contact us and we will investigate and take appropriate action.

9. International Users

If you access Helium from outside the United States, your information will be transferred to and processed in the United States.

10. Changes to This Policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last Updated" date on this page. Continued use of the Services after changes are posted constitutes acceptance of the updated policy.
