Privacy Policy
Last updated: August 3, 2026. This policy describes how CardWhisper handles information when you use cardwhisper.com.
Who we are
The site is operated by CardWhisper. For privacy questions, email support@cardwhisper.com.
Spending inputs (localStorage)
You can enter monthly spending and related preferences to personalize rankings. Those values are stored in your browser's localStorage so they survive reloads. We do not require an account. Spending amounts are not written into analytics events.
Shared ranking links
When you share a rankings link, we may cache the associated spending profile and ranking response on our servers so the recipient sees the same results. Cached share data is retained for up to 30 days, then expires. Anyone with the link can view that snapshot until it expires.
Analytics and session replay
When PostHog is configured, we collect product analytics by default to understand how the site is used. Session replay is also enabled by default, with all inputs and on-screen text masked, and with sensitive UI (such as the spending editor and personalized value displays) blocked from capture. We respect Do Not Track where the analytics library supports it. You can opt out below or from the site footer; opt-out is stored in your browser and stops further capture.
Analytics preference
Product analytics and session replay are on by default when configured. Inputs and on-screen text are masked; sensitive UI is blocked from replay. You can turn capture off at any time.
Current status: capturing (when configured)
Affiliate links
Some “Apply” links are affiliate links. If you apply through them and are approved, we may earn a commission at no extra cost to you. Affiliate relationships do not change how we calculate rankings. See our terms for more detail.
