Privacy Policy

Last updated: 13 September 2026

Short version: there is almost nothing to collect. StackTools has no accounts, no sign-up, no tracking or advertising cookies, and we sell or share data with no one.

Most tools run entirely in your browser — what you paste never leaves your device. A few tools (webhook tester, subdomain finder) send your input to our server to perform the request, then return it; that input is not stored. Our hosting provider processes standard request data (IP address, timestamp, user agent) to serve and secure the Site, and server-backed tools enforce per-IP rate limits held briefly in memory to stop abuse. None of this is used to profile you.

Server-backed tools contact external services on your behalf (certificate transparency logs, or a URL you supply); those services have their own privacy practices. Donations go directly over the Solana blockchain, which is public by nature; we collect no payment details.

We may update this policy; the date above shows the latest revision.
