Privacy Policy

1. Introduction

Tandem ("we", "our", or "us") is a coparenting coordination app that helps separated and divorced parents share custody calendars, notes, messages, and requests. This Privacy Policy explains how we collect, use, and protect your information when you use our app. By using Tandem, you agree to the practices described here.

2. Information We Collect

Account Information

When you register, we collect your email address and a display name. We use this to identify you and link you to your coparent via a shared family code.

Family & Child Information

You may provide your child's name, your coparent's name, custody schedule details, calendar events, notes, messages, expense requests, and schedule change requests. This data is shared with your linked coparent.

Payment Information

If you upgrade to Premium, payment processing is handled by Stripe. We do not store your full card number or banking details on our servers — Stripe securely processes all transactions.

3. How We Use Your Information

• To create and manage your coparenting profile and shared family data.
• To display custody schedules, events, notes, and messages to you and your linked coparent.
• To process premium subscriptions and manage billing.
• To provide AI-powered tone filtering on messages (Premium only).
• To send service-related notifications and account updates.
• To improve, maintain, and secure the app.

4. Data Sharing

Your family data (calendar events, notes, messages, requests) is shared with your linked coparent through your shared family code. We do not sell your personal information. We share data only with trusted service providers who help us operate the app (such as Stripe for payments and AI providers for tone filtering), and only to the extent necessary to provide those services.

5. Data Security

We take reasonable measures to protect your data using industry-standard security practices, including encrypted data transmission and access controls. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

6. Your Rights

You have the right to:

• Access the personal data we hold about you.
• Request correction of inaccurate information.
• Request deletion of your account and associated data.
• Cancel your premium subscription at any time.

To exercise these rights, use the Delete Account option in the app's Settings or contact us.

7. Children's Privacy

Tandem is designed for adult coparents. While the app stores information about your child (such as their name and schedule), the app is not directed at children under 13 and we do not knowingly collect personal information directly from children.

8. AI & Message Processing

For Premium users, messages may be analyzed by an AI model to detect hostile or unconstructive tone and suggest gentler rewrites. This processing is done to encourage respectful communication. You always have the option to send your original message or cancel.

9. Data Retention

We retain your data for as long as your account is active or as needed to provide the service. When you delete your account via Settings, your profile, custody events, and shared notes are permanently removed.

10. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected within the app with an updated revision date. Continued use of the app after changes constitutes acceptance of the updated policy.
