Privacy Policy

Last updated: May 31, 2026

1. Data We Collect

• Account data: Email address, display name, professional role
• Subscription data: Subscription tier, billing status (managed by Stripe)
• Saved patient records (Pro): If you use the patient manager, the animal names, species, weights, and free-text notes you enter are stored to your account so you can reuse and reprint them. These are user-entered animal records, not human health information, and are not treated as HIPAA-covered data.
• Calculation history: Your recent dose calculations are stored to your account so you can revisit them.
• Usage data: Calculation counts and product-usage analytics events (see §3)

Email use. We use your email address to send account, security, and billing messages, and — only if you opt in — a newsletter and occasional formulary updates. You can unsubscribe from marketing email at any time via the link in every such email or at /unsubscribe; transactional account and billing emails are sent regardless.

2. Data We Do Not Collect

• Payment card details (handled entirely by Stripe)
• We do not sell your personal information or use it for cross-context behavioral advertising
• We do not collect human patient/health data, and the Service is not intended for human medical use

3. Service Providers & Third Parties

We share the minimum data necessary with the following providers so the Service can function. We do not sell your data.

• Keycloak: Authentication, self-hosted on our own infrastructure
• Stripe: Payment processing (Stripe Privacy Policy)
• PostHog (PostHog, Inc., United States): Product-usage analytics. Loaded only with your consent and routed through a same-origin proxy; when you are signed in, analytics events are associated with your account identifier (PostHog Privacy Policy)
• Cloudflare: Bot protection (Turnstile) on our sign-up and contact forms, optional privacy-first Web Analytics, and CDN/security (Cloudflare Privacy Policy)
• Email delivery: A third-party email provider delivers our account, billing, and (opt-in) newsletter messages
