Tend ("we", "us", "our") operates the Tend mobile application. This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our app.
Information We Collect
We collect the following types of information:
Account Information: Email address, display name, and profile photo when you create an account.
Optional Profile Data: Date of birth and phone number, if you choose to provide them during onboarding.
Connection Data: Information about your connections, including names, relationship types, love languages, important dates, and notes you add.
Usage Data: How you interact with nudges (acted on, dismissed, skipped) to improve nudge quality.
Device Information: FCM token for push notification delivery, device type, and timezone.
How We Use Your Information
To generate personalized nudges using AI (Claude by Anthropic) based on your connections' love languages and your communication style.
To send push notifications for nudges, warmth signals, and connection requests.
To match connection requests between users via email lookup.
To improve nudge effectiveness through anonymized engagement metrics.
AI Processing
We use Anthropic's Claude AI to generate personalized nudge suggestions. The information sent to the AI includes your connection's name, relationship type, love language, and your communication style. This data is processed in real-time and not stored by the AI provider beyond the request.
Data Storage
Your data is stored securely in Google Firebase (Firestore) with the following protections:
Data is encrypted in transit and at rest.
Firestore security rules ensure you can only access your own data.
Profile photos are stored as compressed data within your user document.
Data Sharing
We do not sell your personal data. We share data only in these cases:
With your connections: When you send a connection request, your name and photo are shared with the recipient. Warmth signals are shared with your mutual connections.
Service providers: Google Firebase (hosting, auth, database), Anthropic (AI nudge generation), Apple (push notifications, payments).
Legal requirements: If required by law or to protect our rights.
Your Rights
Access: View your data in the app's Settings.
Correction: Edit your profile, love language, and communication style at any time.
Deletion: Delete your account from Settings > Delete Account. This permanently removes all your data from our servers.
Portability: Contact us at privacy@tend.guru to request a copy of your data.
Data Retention
We retain your data for as long as your account is active. When you delete your account, all associated data (connections, nudges, notifications, effectiveness scores) is permanently deleted within 30 days.
