Privacy Policy

The free tools on this site (calculators, converters, steganography, the PDF toolkit, etc.) run entirely in your browser. Files you upload or text you enter are processed client-side with JavaScript/WebAssembly and are never sent to our servers, unless a specific tool’s own page says otherwise (for example, the Site Safety Inspector and My Internet Profile tools make a server-side network request as part of what they do, described on those pages).

Sign-in-gated tools are authenticated via Si-des Auth, a separate identity provider. We never see or store your password — Si-des Auth handles authentication and hands this app a signed identity token (your email, username, and a stable user ID) after you sign in. For what Si-des Auth itself collects during sign-in (security telemetry, audit logs, etc.), see its own Privacy Policy.

This app sets two cookies, both strictly functional:

• A signed session cookie, set once you sign in, that keeps you recognized as you browse gated tools.
• A short-lived PKCE relay cookie used only while a sign-in is in progress, deleted once it completes.

Neither is used for advertising or tracking, and there is no cross-site tracking cookie on this app to opt out of.

We don’t sell or share your data with third parties. Your identity claims come from, and any security-relevant data about your sign-ins is recorded by, Si-des Auth — not this app.
