1) No accounts, in-browser math

We don’t require accounts or logins. Calculator inputs run locally in your browser; we don’t receive or store them on our servers.

Market prices come from public APIs (e.g., CoinGecko) and may be delayed or temporarily unavailable.

2) Ads & affiliates

We may show standard ads and clearly labeled affiliate links. If you click and sign up or buy, we may earn a small commission at no extra cost to you. These help keep our tools free.

• Affiliate links use rel="sponsored nofollow".
• Partners don’t influence calculator outputs or our content.

3) Cookies & tracking

Some third-party vendors (e.g., ad networks) may use cookies to deliver or measure ads. You can usually opt out of personalized ads in vendor settings.

Your browser also lets you block third-party cookies or use stricter privacy settings if you prefer.

4) Analytics (optional)

If enabled, we use privacy-friendly analytics (no fingerprinting, no cross-site tracking) to understand usage at an aggregate level — e.g., which pages are popular — so we can improve the product.

5) Data retention

We avoid collecting personal data. Any logs we keep are minimal, short-lived, and used only to keep the site secure and reliable.

6) Contact & changes

Questions or requests? Email mailswept.contact@gmail.com.

We may update this policy from time to time. Continued use of the site means you accept the latest version.
