Privacy Policy

Last Updated: November 3, 2025

Our Commitment to Privacy

PetMed Helper is built with a privacy-first, local-first approach. We believe your pet's health information should stay private and under your control.

What We Collect

Short answer: Nothing that identifies you personally.

Analytics

  • We use Ahrefs Web Analytics to understand how our calculators are being used
  • This helps us improve the tools and ensure they're meeting pet owners' needs
  • Analytics data is anonymized and aggregated

No User Accounts

  • We do NOT require registration or login
  • We do NOT collect names, email addresses, or contact information
  • We do NOT track individual users across sessions

Where Your Data Lives

Local Storage Only

All calculator history and results are stored exclusively in your browser:

  • IndexedDB: Stores your calculation history for quick reference
  • localStorage: May store preferences (like unit selection)

Important: This data NEVER leaves your device. It's not sent to our servers or any third party.

Clearing Your Data

You can delete all stored data at any time by:

  1. Clearing your browser's local storage
  2. Using your browser's "Clear browsing data" feature
  3. The data is tied to your browser on your device only

What We DON'T Do

  • ❌ We don't sell your data to anyone
  • ❌ We don't share your data with third parties (except anonymized analytics)
  • ❌ We don't store your pet's information on our servers
  • ❌ We don't require email addresses or accounts
  • ❌ We don't use cookies for tracking (only essential session cookies)
  • ❌ We don't have access to your calculation results
  • ❌ We don't use advertising trackers

Third-Party Services

Ahrefs Web Analytics

We use Ahrefs Web Analytics for understanding site usage:

  • Privacy-focused analytics
  • No personal data collection
  • Anonymized visitor statistics

Vercel Hosting

Our site is hosted on Vercel:

  • Standard server logs (IP addresses, request times)
  • Used only for security and performance monitoring
  • Not used for tracking individual users

URL Sharing Feature

Our calculators include a "Share" button that encodes your calculation results in the URL:

  • This allows you to share your specific calculation with others (like your vet)
  • The data is encoded in the URL itself - not stored on our servers
  • Only share these URLs if you're comfortable with the recipient seeing your calculation

Example: petmedhelper.com/calculators/chocolate?weight=25&amount=100

Medical Information Disclaimer

PetMed Helper does not store or process medical records.

  • All calculations happen in your browser (client-side)
  • We never see your inputs or results
  • We cannot access your calculation history

Summary (TL;DR)

  • ✅ Your calculations stay in your browser
  • ✅ We use privacy-focused analytics (aggregated only)
  • ✅ No accounts, no tracking, no data sales
  • ✅ Free forever, no hidden costs

Your pet's health information is sensitive. We built PetMed Helper to respect that by keeping your data local and private.
