Privacy Policy
Last updated: July 30, 2026
SizerTrade ("we", "us", or "the Service") is an individually-operated educational calculator and content site for crypto futures trading. This page explains what information is collected when you use the Service and how it is used.
1. Information We Collect
The Service does not require an account, so we do not collect names, passwords, or similar account credentials. The following information may be collected automatically or provided voluntarily to help us operate and improve the Service.
- Usage data: pages visited, device/browser type, approximate location, and time on site (collected via Google Analytics and Microsoft Clarity)
- Price alert subscriptions: if you opt in to browser push notifications, a per-browser subscription token is stored to deliver alerts (this is not personally identifying)
- Contact form submissions: any message you send through the contact form, and any contact information you voluntarily provide if you want a reply
2. Cookies and Similar Technologies
The Service uses cookies and similar technologies (such as local storage) for usage analytics and advertising. You can block or delete cookies in your browser settings; doing so may limit some features.
3. Third-Party Services
We rely on the following third-party services to operate the Service. Each processes data under its own privacy policy.
- Google Analytics — visitor analytics
- Google AdSense — advertising (once approved and enabled)
- Microsoft Clarity — session recording and heatmap-based UX analysis
- Vercel — website hosting
- Upstash (Redis) — storage for news and blog content

4. Google AdSense and Advertising Cookies
If Google AdSense is enabled on the Service, Google and its advertising partners may use cookies to serve ads based on your interests. You can learn more about how Google uses cookies for advertising on Google's advertising policy pages, and you can opt out of personalized advertising through Google Ads Settings.
5. How We Use and Retain Information
Collected information is used only to improve service quality, diagnose issues, and respond to inquiries. We do not sell information to third parties. Messages submitted through the contact form may be deleted within a reasonable period after they are handled.
6. Your Choices
You can decline or delete cookies at any time via your browser settings, and unsubscribe from push notifications at any time. If you would like information you submitted via the contact form deleted, you can request this through the Contact page.
7. Children's Privacy
The Service is not directed at children under 14, and we do not knowingly collect personal information from them.
