Privacy Policy

Effective: April 2026

1. What We Collect

When you create an AquaHarmony account, we collect the following information:

2. How We Use It

We use your data to provide the Service — displaying your tank dashboard, calculating compatibility scores, and storing your water chemistry history. We do not use your data for advertising and we do not sell your personal information to third parties.

3. Payment Processing

Payments are processed by Dodo, our payment provider. AquaHarmony does not store your payment card details. Dodo's privacy policy applies to all payment processing. You can review Dodo's privacy policy at dodo.com/privacy.

4. Data Storage and Security

Your data is stored in a database managed by AquaHarmony. We use reasonable security measures to protect your data, but no system is 100% secure. You use the Service at your own risk.

5. Cookies

We use minimal session cookies to keep you logged in. We do not use advertising cookies or tracking cookies.

6. Your Rights

You can export or delete your account data at any time by contacting us at [email protected]. Deleting your account removes your personal data from our records.

7. Data Sharing

We do not share your personal data with third parties except as necessary to provide the Service (for example, Dodo for payment processing) or as required by applicable law.

8. Children's Service

AquaHarmony is not intended for users under the age of 18. We do not knowingly collect data from minors.

9. Changes to This Policy

If we make material changes to this Privacy Policy, we will update the effective date and, for significant changes that affect your rights, notify you via email.
