Privacy Policy

Introduction

Calen is an AI companion service for adults, available through Telegram, WhatsApp, and phone calls. This Privacy Policy explains how we collect, use, store, and protect your personal information when you use our service.

By using Calen, you consent to the data practices described in this policy. If you do not agree with our practices, please do not use our service.

What We Collect

Account Information

When you start using Calen, we collect:

• Your name (as provided by you or your messaging platform)
• Your phone number or messaging platform user ID
• Your preferred communication channel (Telegram, WhatsApp, or phone)
• Account creation date

Persistent Memory Data

Cognitive Pattern Observations

As part of the memory feature, Calen may note conversational patterns such as repeated questions or changes in communication habits. These observations are stored in your personal memory file and are used solely to provide better, more attentive companionship. These observations are:

• Never shared with anyone - not family, not gift-buyers, not third parties
• Not a medical assessment - Calen is not a healthcare provider
• Deletable - you can request removal at any time

Conversation Data

Calen maintains conversation context to provide meaningful responses. This includes:

• Text messages sent to and from Calen via Telegram and WhatsApp
• Transcriptions of voice messages (see Voice Processing below)
• Transcriptions of phone call conversations (see Voice Processing below)
• Documents and images you forward to Calen for explanation

Voice Processing

Payment Information

Gift purchases are processed through PayPal. We do not store your payment card details - PayPal handles all payment processing securely. We only store:

• PayPal transaction IDs
• Gift status (active/expired/refunded)
• Gift activation and expiry dates
• Payment amounts

How We Use It

Core Service Functionality

We use your data to:

• Provide AI companion conversations through Telegram, WhatsApp, and phone calls
• Maintain persistent memory so Calen remembers you between sessions
• Process voice messages and phone calls into text
• Send medication reminders based on information you provide
• Analyze documents, bills, and letters you forward for explanation
• Analyze suspicious messages you forward for scam detection

Account Management

• Identify your account across messaging channels
• Process gift payments via PayPal
• Provide customer support when requested

Service Improvement

• Monitor system performance and identify technical issues
• Detect and prevent abuse or fraudulent activity

Gift-Buyer Model

Calen is purchased as a gift - for example, by adult children for their parents. The person who bought the gift does not have access to your conversations or personal data.

Where It's Stored

Primary Storage

• Application server: Hetzner VPS (located in Finland)
• Memory files: Per-user Markdown files stored on the server
• Each user's data is completely isolated - there is no cross-user access

Data Protection Measures

• All data is encrypted in transit using TLS 1.3
• Server access protected by SSH keys and firewall rules
• Per-user data isolation - each user has a separate memory file
• Regular automated backups with encryption
• Access controls limit data access to essential operations only

Data Retention

• Active user data is retained while your account is active
• Memory files persist between conversations (that's the point)
• Voice recordings are NOT stored - only transcriptions are retained
• Phone call audio is NOT recorded - only real-time transcription occurs
• After your plan expires, data is retained for 90 days. If not renewed within that window, all personal data is permanently deleted
• After account deletion, all data is permanently removed within 7 days, backups within 90 days

We work with the following third-party services to operate Calen Life:

Data Sharing Limitations

Service Improvement Use

We may use anonymized, de-identified conversation themes to improve our service and messaging. This means we may observe general patterns across conversations (for example, that many users ask about weather or medications) to make Calen more helpful. No personal details, names, or identifiable information are ever used in this process. Your individual conversations remain private.

Selective Deletion

You can ask Calen to forget specific information at any time. Simply say "forget [information]" in conversation, and Calen will remove that item from your memory file.

You can request complete deletion of your account and all associated data by:
