Privacy Policy
Basic Policy
toco.tools ("this site") primarily provides tools that run in your browser. Tools that handle sensitive input (passwords, keys, PDFs, images, and similar) do not send or store that input on our servers. Some tools that need external data — DNS / WHOIS / SSL / HTTP header checks, IP info, currency and crypto rates, postal-code lookup, and market indicators — query through our servers. Only the minimal parameters needed for the lookup (hostname, IP, currency pair, postal code, etc.) may be held briefly in server memory for rate limiting and caching; they are not stored permanently. For investment share links and social cards, amounts, returns, and other conditions in the URL are sent to the server to generate the image. Recipients can also see those conditions. If you use optional accounts (email auth and favorites sync), credentials and favorite tool and article identifiers are stored on the server.
Cookies & Local Storage
Your language is saved in a browser cookie (NEXT_LOCALE) only when you switch it. Opening a link in another language does not clear that choice. If you have not switched, “/” follows your browser language. Theme preference and recently used tools are stored in localStorage. Favorites stay on-device when you are signed out. When you sign in and sync, favorite tool and article identifiers are stored on the server (D1).
Advertising
This site may use third-party advertising services (Google AdSense). Advertising vendors may use cookies to serve ads based on your interests. You can opt out of personalized advertising via Ads Settings. For more details, see Google's policies and terms.
