yoyosup tools run in your browser. ScamCheck, LinkCheck, and PassCheck process your input locally or via our API only to return a result — we do not sell personal data. Scam text you paste is scored in your browser and is not stored as message content on our servers.
We log anonymous visit counts (page views, tool usage totals, optional campaign tags like ?ref=) to understand which tools help people.
For rough geography we count visits by country and sometimes state/region, using headers from our CDN (Cloudflare). We do not use this to identify you, and we do not store city-level location or GPS. We may also count the referring website host name (for example google.com) without storing the full URL.
If you use the Feedback button, we store the message you send, the page you were on, and the same rough country/region. If you choose to leave an email, we keep it only so we can reply — we do not sell it or add you to a marketing list. You can always leave feedback without an email.
We do not sell personal data. Aggregate stats are for operating and improving free tools.
We use Google AdSense to show ads on some pages. Google and its partners may use cookies to serve ads based on your visits to this and other sites. You can opt out of personalized advertising at google.com/settings/ads.
yoyosup is not directed at children under 13. We do not knowingly collect data from children.
Questions about this policy or the tools: use the Feedback button on any tools page (optional email if you want a reply), or reach the site owner at yoyosup.com.
