Privacy Policy

Last updated: July 23, 2026

1. Data We Collect

We collect the following data when you use Kaylio:

• Account data: Email address, subscription status
• Conversation data: Messages you send and receive from your AI companion
• Memory data: Facts, preferences, and emotional context extracted from conversations, stored as semantic vector embeddings
• Usage data: Message counts, session duration, feature usage
• Payment data: Processed by Stripe — we do not store credit card numbers

2. How Memories Work

Kaylio extracts key information from your conversations to help your companion remember you. Memories are stored as:

• Short text summaries (e.g., "User is allergic to peanuts")
• 768-dimensional vector embeddings used for semantic search
• Importance scores and type classifications

You can view, edit, pin, and delete any memory through the Memory Journal in your companion's chat.

3. Third-Party Services

We use the following third-party services to operate Kaylio:

• Supabase: Database and authentication
• Google Gemini / OpenRouter: AI language model for conversations and memory extraction
• OpenAI: Text-to-speech voice generation (paid tiers)
• Replicate: AI image generation (paid tiers)
• Stripe: Payment processing
• Vercel: Website hosting and infrastructure
• Sentry: Error monitoring — technical error reports and diagnostics; never the content of your conversations
• PostHog: Product analytics — feature usage and signup-funnel events tied to a pseudonymous account identifier; never the content of your conversations
• Microsoft Clarity: Session replay and heatmaps on our public marketing pages only — never inside the logged-in app and never your conversations — to understand how visitors use our site
• Reddit: Advertising conversion pixel on public marketing pages, reporting anonymized signup conversions so we can measure our ads
• Telegram: Operational alerts to the Kaylio team about account activity — signups, onboarding, first messages, subscription changes — and the text of any feedback you submit. Includes a shortened account identifier, your chosen companion type, and the page you were on (e.g. when submitting feedback); never your account email address, and never the content of your conversations.

4. Data Retention

Your data is retained for as long as your account is active. Conversation memories are retained according to your subscription tier (Free: 30 days, Core: 1 year, Deep: unlimited).

5. Your Rights

You have the right to:

• Export your data: Download all your data as JSON from Settings
• Delete your account: Permanently delete all data from Settings — this is irreversible and cascades to all companions, messages, and memories
• Edit or delete memories: Through the Memory Journal

6. Safety Logging

When our crisis detection system identifies potential signs of distress, we log a brief, anonymized record (category and first 200 characters) to monitor system effectiveness. This data is used solely for safety improvements and is not shared with third parties.
