Privacy policy

Every tool except the BIN checker, Temporary Email and the Webhook — the JSON formatter, SQL formatter, string & ID formatter, text transform tool, JSON ↔ CSV converter and JSON compare — processes everything locally in your browser. Nothing you paste into those tools is transmitted to or stored on any server.

The BIN checker is a partial exception: the first 6-8 digits you enter are sent directly from your browser to the third-party binlist.net lookup API. The rest of any card number is discarded before that request is made, and nothing is stored on our servers. This tool identifies a card's issuer, network and country — it does not validate whether a card number is real or usable.

The Temporary Email tool stores data on our servers by necessity: it issues a disposable address and stores mail delivered to it — headers, body and attachments — so it can be shown back to you. An address accepts new mail for 7 days or 15 messages, whichever comes first, after which the address and everything it captured are deleted automatically. There is no download step and no recovery window — once an address expires or is deleted, its mail cannot be retrieved. HTML mail is rendered in a sandboxed frame with scripts disabled.

The Webhook is the other tool that stores data on our servers: it issues a temporary URL and stores the requests delivered to it — method, path, query string, headers, body and originating IP address — so they can be shown back to you. Authorization, Cookie, Proxy-Authorization, X-Api-Key and X-Auth-Token headers are redacted before storage; the body itself is stored exactly as received. Sessions accept new requests for 7 days (or up to 100 requests, whichever comes first), and you can clear the history at any time. Undownloaded data is purged automatically 7 days after a session expires.

This site reserves space for ads served by Google AdSense. No ads are being served yet — the ad slots currently render as empty placeholders. Once enabled, AdSense may set cookies and use similar technologies to serve and measure ads, including ads based on your prior visits to this or other websites. You can opt out of personalized advertising via Google's Ads Settings or aboutads.info/choices. Visitors in the EEA, UK and Switzerland will be shown a consent prompt before any personalized ad cookies are set, once ads are enabled. None of this affects tool input, which is never used for ad targeting.

There are no user accounts. Your webhook or temporary-email session identifier is kept in your browser's local storage so the page can reconnect you to the same session; clearing site data removes it.
