Using Duoheart
Duoheart is a private, end-to-end encrypted space for two people who have chosen to pair with each other. By creating an account, you agree to use it only with a partner who has consented to share the space with you.
Your account
You’re responsible for keeping access to your device and email secure. Because we can’t decrypt your conversation, we also can’t recover it if you lose access to every device holding your keys - please keep at least one device signed in and trusted.
Founding couples and pricing
The first 50 couples to pair in Duoheart are founding couples. They use Duoheart free of charge for as long as the service exists, with no payment method required. Couples who join after that may be offered a monthly subscription at the price shown in the app store at the time of purchase, with a free period before any charge. You can cancel anytime from your app store subscription management.
Acceptable use
You agree not to use Duoheart to:
- Harass, threaten, or abuse another person.
- Share content that is illegal in your jurisdiction.
- Attempt to access another user’s encrypted data or keys.
- Interfere with or disrupt the service or its infrastructure.
Content ownership
You own what you and your partner create in Duoheart, and we make no claim over it. Your chat, your answers, your photos and your calls are end-to-end encrypted, so we have no access to those at all. The optional AI features are the exception: what you write to them is readable by us and by our model providers, as the Privacy Policy sets out.
Termination
You can delete your account at any time, which permanently deletes your encrypted data. We may suspend accounts that violate these terms.
Disclaimer
Duoheart is provided “as is.” While we design the system so that we cannot read your data, no software is guaranteed to be free of defects - keep independent backups of anything irreplaceable.
