How we handle your data
Last updated: 11 May 2026
This page is the plain-language version. It complements the privacy policy; if they appear to disagree on a point, this page is the more specific one and should be treated as authoritative.
Where data goes
Tools on Toolhub run in your browser. Anything you paste, type, or upload into a tool stays on your device โ we do not have a server-side tool runner, and there is no upload endpoint behind any of the tools.
There are exactly three named exceptions to "no data leaves your device":
- YouTube Thumbnail tool โ when you submit a YouTube URL, your browser fetches the thumbnail directly from
i.ytimg.com(YouTube's public image CDN). No authentication, no upload, no API key. The video ID in the URL is the only thing YouTube sees, and only because your browser fetched it. - AdSense (only if enabled and consented) โ Google's display-ad system. When you grant ad consent, Google can see your IP address and may set cookies, governed by Google's policy. When you decline (the default), AdSense is not loaded at all.
- Plausible analytics โ counts page visits, referrer, country and device class. No cookies, no fingerprinting, aggregate statistics only. Plausible's servers are EU-hosted.
What we store
Nothing about you. No accounts, no user IDs, no email, no profile. We do not store the content you put into tools.
Your browser stores two small localStorage entries on your device only โ both readable and clearable from your browser's developer tools:
themeโ "light" or "dark", roughly one byte of preference.toolhub:consentโ your ad consent decision (yes/no/unset). Used to avoid asking you again.
GDPR, UK GDPR, CCPA and the Slovak DPA
Toolhub processes minimal data:
- EU / UK (GDPR / UK GDPR): Plausible (EU-hosted) gives a compliant analytics baseline. When AdSense is active, Google operates its own consent layer under TCF v2.
- California (CCPA): we do not sell personal information. We do not have personal information to sell.
- Slovakia (Slovak Data Protection Authority): Toolhub's maintainer is based in Slovakia. The Slovak DPA's rules apply to any processing that does occur โ which is essentially limited to Plausible's aggregate metrics and (when enabled) AdSense's own consent-managed flow.
Rights to access or delete personal data effectively do not apply because no personal data is stored to access or delete. If you have specific questions, contact us via the contact page.
Cookies
- Plausible: no cookies, ever.
- Theme preference: one localStorage entry, not a cookie. Stays on your device. Not transmitted with HTTP requests.
- AdSense (when active): Google sets its own third-party advertising cookies. The consent banner appears before any AdSense script is loaded, and AdSense is not loaded at all if you decline.
Children
Toolhub is school-friendly (see Toolhub for schools). There is no behavioral tracking and no targeted advertising. Under-13 use is acceptable within the existing AdSense terms applied per region โ meaning if you are in a region where AdSense restricts ads to children, those restrictions are honored by Google's own systems.
