SIMPLE ON THE OUTSIDE. SERIOUS UNDERNEATH.
Security. Plainly.
Here's what we protect today. And what we're still building.
PRIVATE BETA / SAMPLE ONLY. Do not enter real banking information. PaprChk is not yet approved for negotiable check printing.
In place today.
DEVELOPMENT CONTROLSSign-in required. Protected checkbook pages use Supabase authentication.
Workspace separation. Database row-level security restricts personal records to their creator; direct anonymous table access is denied.
Check number protection. Sample check numbers are assigned in database transactions with a uniqueness constraint.
Audit events. Creating or updating sample check records writes audit entries.
Sample printing only. Printable tests have permanent SAMPLE / VOID markings and contain no bank identifiers or MICR information.
Before real checks.
NOT YET RELEASEDBank-account ownership checks, application-level encryption and key management, MFA for sensitive operations, bank/printer acceptance tests, abuse protections, privileged-function hardening, multi-user isolation testing, and an independent security assessment are still required.
Good to know.
Sent and Cleared are manual checkbook labels. PaprChk does not independently verify bank delivery, deposit, or settlement.
Void in PaprChk does not cancel a check or stop a payment at the bank. Contact your bank for stop-payment requests.
We do not claim that PaprChk is SOC 2 certified, bank-certified, or fraud-proof.
