Anonymize a single IP address — mask octets or hash for analytics. Share logs without exposing users — local processing, free, no signup.
Generate PGP key pairs with OpenPGP.js — public for sharing, private stays local. Encrypt mail like it's 1991 but working — local crypto, unlimited saves.
Scan and clear cookies, localStorage, and sessionStorage for the current site — see what's stored first. Audit privacy trackers before wiping — local inspection, free, no signup.
Parse any URL into its components — protocol, hostname, path, query parameters, hash, and more with copy-to-clipboard. Host, path, query, and fragment split with decoding — debug redirect chains precisely. Runs locally, free, no signup.
Generate random tokens in hex, base64, or alphanumeric formats for secrets and sessions. Hex and base64 draw from Web Crypto (alphanumeric uses Math.random — see format notes). The API-key preset mints 64-char secrets in one click — local generation, free, no signup.
AES encryption happens in your browser with crypto-js; the ciphertext rides in the URL fragment (#note=), which browsers never send to servers. But the key travels in the link query (?key=), which servers and logs can see — and opening a link auto-decrypts, then wipes the fragment from the address bar. Treat the full link as the secret.
Without the password it's unreadable AES ciphertext. Share passwords out-of-band (call, different channel) — link plus password together defeats the purpose.
No server means no remote deletion — anyone with link + password re-reads forever. Rotate exposed secrets after one-time shares.
No plaintext is stored server-side, but the key travels in the link query (?key=) so servers and logs can see it — never use these links for banking or high-stakes secrets. A blank password auto-generates an 8-character key.
