Privacy Policy

Last updated: February 2, 2026

The Short Version:

Your financial data (credit cards, balances, APRs) never leaves your device. All calculations run 100% in your browser using localStorage. We cannot see, access, or store your financial information.

Data We Don't Collect

Senaro is designed with privacy-first architecture:

  • Credit card information - stored only in your browser's localStorage
  • Account balances - never transmitted to any server
  • APR rates - processed entirely on your device
  • Calculation results - generated locally, not logged
  • Personal identification - no accounts or logins required

Analytics We Do Use

We use Google Analytics to understand how visitors use our site. This helps us improve the calculator and user experience. Google Analytics collects:

  • Pages you visit on senaro.ai
  • How long you spend on pages
  • Your general geographic region (country/city level)
  • Device type and browser information
  • Referral source (how you found us)
  • Calculator usage events (e.g., calculation completed, strategy selected)
  • Aggregated debt ranges (e.g., "under $5K", "$10K-$25K") — NOT your actual balances
  • Number of cards entered and whether cash advances are present

Important: We track aggregated ranges and counts, not your actual financial numbers. Your specific balances, APRs, and payment amounts never leave your browser and are never sent to Google Analytics or our servers.

Pro Waitlist Email Collection

If you choose to join our Pro waitlist, we collect your email address to:

  • Notify you when Pro features become available
  • Send occasional product updates (you can unsubscribe anytime)

Your email is never sold or shared with third parties. It is stored securely and used only for Senaro communications. Joining the waitlist is completely optional—the free calculator works fully without providing any email.

Cookies

We use cookies for:

  • Google Analytics - to distinguish unique visitors and sessions
  • localStorage - to save your credit card data locally on your device (this is not technically a cookie, but browser storage)

You can disable cookies in your browser settings. If you do, Google Analytics won't track your visits, but the calculator will still work (though your saved cards won't persist between sessions).

Data Security

Because your financial data stays on your device:

  • There's no database to breach
  • There's no API transmitting sensitive data
  • Your data is as secure as your own device

Tip: Use the Export feature to back up your card data. If you clear your browser data or switch devices, your saved cards will be lost.

Children's Privacy

Senaro is not intended for use by anyone under 18 years of age. We do not knowingly collect information from children.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
