Privacy Policy

What data we collect

We collect account information (email, full name), trading data you import (trades, strategies, emotions), and usage data necessary to provide the service (e.g. AI query count, feature usage). We do not sell your personal or trading data.

How we use it

Your data powers the dashboard, AI analysis, and analytics. We use it to generate insights, run performance metrics, and improve the product. Aggregated, anonymized data may be used for product improvement and research.

Data storage

Data is stored using Supabase on secure cloud infrastructure (AWS). We use industry-standard encryption (SSL/TLS) in transit and at rest, and apply access controls and monitoring.

Third parties

We use Stripe for payment processing (subscription and billing). Stripe processes payment data according to their privacy policy. We use Anthropic for AI-powered analysis; trade data sent to the AI is used only to generate your responses and is not used to train models on your personal data. We do not share your data with other third parties for marketing or advertising.

Cookies

We keep cookies minimal and transparent. Below is exactly what we set — no hidden trackers, no ad networks, no surprises.

Cookies we use

1. Authentication cookie (essential)
   • Name: sb-*-auth-token (Supabase session)
   • Purpose: Keeps you logged in securely.
   • Duration: Typically up to 7 days, refreshed when you use the app.
   • Type: Essential — required for login and cannot be disabled without losing access to your account.
2. Preferences (functional)
   • Name: blotter_preferences
   • Purpose: Saves display settings (e.g. reporting currency, theme).
   • Duration: Up to 1 year.
   • Type: Functional — improves your experience without tracking you across the web.
3. Cookie consent (functional)
   • Name: blotter_cookie_consent (stored in localStorage, not a browser cookie)
   • Purpose: Remembers that you've seen our cookie notice.
   • Duration: Until you clear site data.
   • Type: Functional.

Cookies we don't use

• No Google Analytics or similar tracking cookies
• No Facebook Pixel or social media tracking pixels
• No advertising, retargeting, or behavioral marketing cookies
• No third-party cookies for analytics or ads — period

If we ever add optional analytics, we'll only load it after clear opt-in — and we'll update this page. Your trading data stays yours; we have nothing to hide about how Blotter works.

Your rights

You can export your data (trades, settings) from the Settings page. You may request account deletion from Settings or by contacting us. We will delete your account and associated data within a reasonable period, subject to legal retention requirements.

Data retention

We retain your data for as long as your account is active. After account deletion, we remove or anonymize data within 30 days, except where we must retain it for legal or compliance reasons.

Updates to this policy

We may update this policy from time to time. We will post the updated policy on this page and update the "Last updated" date. Continued use of the service after changes constitutes acceptance.
