We do not ask for card numbers, account numbers, account names, logins, Social Security numbers, names, or phone numbers. The feedback form has an optional email field if you want a reply.
What Runs In Your Browser
The payoff calculation runs in your browser. You can use the calculator without creating an account.
What May Be Sent
Calculator inputs and results are not collected automatically for analytics or site improvement. The payoff math runs in your browser.
If you submit the feedback form, your message, optional email address, page path, anonymous report ID, and basic browser/device details are sent to Supabase. You can choose whether to attach the current calculator input snapshot and result summary so bugs, comments, and suggestions can be diagnosed. Card nicknames are not included in that diagnostic snapshot.
The app may store a random anonymous report ID in local storage when you submit feedback so related reports from the same browser can be grouped without asking who you are.
Copying a share link is different from feedback. A share link is created only when you click the share button, and it includes the card nicknames, loan names, and calculator inputs currently shown so the plan can be reopened from that link.
What Is Not Sent
- Card numbers or account numbers
- Bank or card login credentials
- Calculator inputs or results as automatic analytics telemetry
- Names, account names, or identifiers typed into card nickname fields as feedback diagnostics
- Your name, phone number, address, or Social Security number
- Your email address, unless you choose to include it in the feedback form
Analytics
The site does not currently load third-party analytics scripts or send calculation analytics events.
Service Providers
Current service providers include Vercel for site hosting and Supabase for feedback report storage. These providers may process technical information needed to deliver those services.
Retention And Changes
Feedback reports and optional diagnostic attachments are used for product improvement and debugging. Because feedback can be submitted without an account or email address, deletion requests may be limited if we cannot identify which anonymous rows belong to a specific visitor.
If this project later adds accounts, saved plans, marketing email signup, affiliate links, ads, or additional personally identifying data collection, this page should be updated before those features go live.
Contact
Questions, comments, or deletion requests can be sent through the feedback form on the calculator page. Public, non-sensitive bugs can also be opened through the project issue tracker. Do not post card numbers, account numbers, or other sensitive details.
