Privacy Policy

Last updated: February 2026

Birch is a messaging-based service that helps parents support their children's learning at home. This Privacy Policy explains how we collect, use, and protect your information when you use Birch via WhatsApp, Telegram, or other messaging platforms.

1. Information We Collect

When you use Birch, we collect:

• Information you provide: Your child's age, school year, language setup, and any learning context you share with us (e.g. what they're currently working on at school).
• Conversation content: Messages you send to the Birch bot and responses we provide. We use this to personalise your experience and improve our service.
• Contact information: Your phone number (via WhatsApp or Telegram), which we use to send your daily messages and respond to your questions.

2. How We Use Your Information

• To deliver your personalised daily activity messages
• To respond to questions you ask about your child's learning and development
• To improve the quality and relevance of our suggestions over time
• To maintain records of what activities have been suggested (so we don't repeat them)

3. Children's Privacy

Birch is a service for parents and caregivers, not children. We do not knowingly collect personal information directly from children. You may share information about your child (such as age and school year) to enable personalised suggestions, but this information is treated as part of your account and is not associated with your child's identity.

We recommend against sharing your child's full name, photograph, or other identifying details beyond what is necessary to personalise your experience.

4. Data Sharing

We do not sell your personal information. We may share data with:

• AI providers: Conversation content is processed by third-party AI APIs (such as Anthropic Claude) to generate personalised responses. These providers process data under their own privacy policies and do not use your data to train their models.
• Infrastructure providers: We use cloud hosting services (AWS) to store your data securely.

5. Data Retention

We retain your conversation history and profile information for as long as you are an active Birch user. You can request deletion of your data at any time by contacting us at hello@withbirch.com. We will delete your data within 30 days of your request.

6. Security

We take reasonable steps to protect your information from unauthorised access, including encrypted storage and secure API communications. No method of transmission over the internet is 100% secure, but we work to protect your data using industry-standard practices.

7. Your Rights

You have the right to:

• Access the information we hold about you
• Correct inaccurate information
• Request deletion of your data
• Opt out of the service at any time by stopping your use and contacting us

8. How We Use WhatsApp

Birch uses the WhatsApp Business API to send you daily educational activity messages and to respond to your questions. We only send messages to users who have explicitly opted in by starting a conversation with the Birch bot. We do not send unsolicited messages or share your WhatsApp contact information with third parties.
