Privacy Policy
Last updated: 2026-06-10
What this site is
Sutekka Tools is a free collection of trading calculators and converters operated by Sutekka. There are no user accounts on this site; you do not submit any personal data to run the calculators. All math runs client-side in your browser.
What data we collect
Two narrow categories:
- Standard webserver logs. Your IP address, request path, user-agent, and timestamp are recorded for abuse prevention and basic operational metrics. Logs are retained for up to 30 days then deleted.
- Cookies set by Google AdSense only after you click Accept on the cookie banner. If you Decline (or never click), no AdSense scripts load and no advertising cookies are set. AdSense uses cookies to show non-personalized or personalized ads depending on your ad-personalization settings in your Google account.
Third parties
- Google AdSense (advertising, after consent). Google's privacy practices are documented at policies.google.com/privacy.
- Yahoo Finance (delayed market quotes powering the ES/SPY/SPX and NQ/QQQ/NDX converters). Quote requests are proxied through sutekka.io so Yahoo doesn't see your IP directly.
Your rights (GDPR / UK / California)
Because we don't hold any account data on this site, most data-subject requests don't apply here. You can:
- Decline cookies via the banner — that's the GDPR Article 7 opt-out for this domain.
- Manage Google ad personalization at myadcenter.google.com.
- Email us at hello@sutekka.io for any other request.
Main Sutekka app
If you have a Sutekka trading-journal account at sutekka.io, the privacy policy covering that account data is here. The two policies are separate because Sutekka Tools and the main app collect different things.
Changes
Material changes to this policy are noted by updating the "Last updated" date at the top. Continuing to use the site after a change constitutes acceptance.
