Dappy integrates with the following third-party services. Each has its own privacy policy which we encourage you to review:

We use the Binance public market data API in read-only mode for price feeds. We do not share any user data with Binance, and we do not facilitate any trading activity. Dappy is not affiliated with or endorsed by Binance.

Dappy is not directed at children under the age of 13 years (or 16 years in the European Economic Area). We do not knowingly collect personal information from children.

If you are a parent or guardian and believe your child has provided us with personal data, please contact us immediately at privacy@dappy.app. If we become aware that we have collected data from a child without verifiable parental consent, we will take steps to delete that information promptly.

Depending on your jurisdiction, you may have the following rights regarding your personal data:

• Access: Request a copy of the personal data we hold about you
• Correction: Request that we correct inaccurate or incomplete data
• Deletion: Request that we delete your personal data ("right to be forgotten")
• Portability: Request your data in a structured, machine-readable format
• Restriction: Request that we restrict processing in certain circumstances
• Objection: Object to processing based on legitimate interests
• Withdraw Consent: Where processing is based on consent, withdraw it at any time

If you are located in the EEA or UK, you also have the right to lodge a complaint with your local data protection supervisory authority.

Push notifications are the core feature of Dappy. Here is exactly how they work with respect to your data:

• On install, you will be asked to grant push notification permission. You can deny or revoke this permission at any time in your device Settings.
• If permission is granted, your device generates a unique device token provided by Apple APNs or Google FCM. This token is stored on our servers associated with your account.
• When a price alert triggers, our server sends a notification payload containing only the pair name and price to the notification service for delivery to your device.
• The device token does not personally identify you and changes periodically. It is used solely for notification delivery.
• You can disable push notifications at any time in your device Settings or within the app via Settings → Notifications. This will not affect your active alert configurations.

Dappy may process and store data on servers located outside your country of residence, including in the United States (Firebase/Google infrastructure).

When we transfer data outside the EEA, we ensure appropriate safeguards are in place including:

• Standard Contractual Clauses (SCCs) approved by the European Commission
• Transfers to countries with an adequacy decision from the European Commission
• Google's data processing terms, which include appropriate international transfer mechanisms

We may update this Privacy Policy from time to time. We will notify you of any material changes by:

• Posting the new policy on this page with an updated "Last Updated" date
• Sending an in-app notification or email if the changes are significant

We will give you at least 14 days' notice before material changes take effect. Your continued use of Dappy after changes are posted constitutes acceptance of the updated policy.

If you have any questions, concerns, or requests regarding this Privacy Policy or our data practices, please contact us:
