Privacy and website data

Website delivery

Cloudflare hosts and helps secure this website. Requests may include network and browser information needed to deliver content and protect the service. See Cloudflare’s privacy policy.

Calculators and downloads

Calculator inputs are processed in your browser and are not submitted to Dollar Feeder. Downloaded worksheets are saved on your device; completing them does not send their contents to this website.

Free accounts and sign-in emails

When account access is enabled, we collect your email address and verification status to deliver free downloads and CSV exports. Supabase manages email verification and stores account records and private resources. Resend delivers sign-in codes through Supabase. Cloudflare runs the account endpoints and provides Turnstile abuse protection. We do not collect passwords, calculator values, worksheet contents, or saved financial profiles.

Essential cookies and retention

Secure, HttpOnly cookies maintain your account session for up to 30 days, protect requests against forgery, and bind a sign-in attempt to your browser for 10 minutes. Signing out revokes the current session; deleting your account revokes every session. Local browser storage remembers a dismissed account invitation for 30 days and limits invitations to one per session. Verification challenges expire after 10 minutes; hashed abuse-limit identifiers expire within 24 hours and are cleared on subsequent authentication activity. Expired sessions are cleared during authentication activity. Anonymous daily operational totals are retained for up to 90 days. Your email and verification record remain until you delete your account; provider security logs and backups follow their retention schedules.

Account deletion and optional newsletter

Choose My account, then Delete my account. A recent email verification is required. Deletion removes your active account record and revokes access on all devices. Account creation never enrolls you in a newsletter. If enabled, the separate Zoho Campaigns hosted signup requires an email confirmation. Use its unsubscribe link to leave the newsletter; unsubscribing does not remove your free account, and deleting your account does not automatically unsubscribe you.

Provider privacy information: Supabase, Resend, and Zoho.
