Privacy Policy

Last updated: September 25, 2026

SmartFinancesHub.com is run by The Bottleneck Lab. This policy explains what information the site handles and why. There are no user accounts, and you can use every calculator without giving us any personal information.

1. Numbers you enter in the calculators

All calculations run in your browser. The figures you type into the calculators are not sent to us or stored by us.

2. Information stored on your device

The site saves your country choice (United States or Canada) in your browser's local storage so it's remembered next time. It stays on your device, and you can remove it by clearing your browser's site data.

3. Analytics

We use Google Analytics to understand how many people visit and which pages they use. Google Analytics uses cookies and collects information such as pages viewed, approximate location, device and browser type. We use this only in aggregate to improve the site. You can read how Google uses information from sites that use its services, and you can opt out with the Google Analytics opt-out browser add-on.

4. Contact form

If you send us a message, we collect your name, email address and message so we can reply. The form is delivered to our inbox through Web3Forms (Web3Forms privacy policy). We don't use your email address for marketing, and we don't sell or share it.

5. Advertising

We plan to show ads through Google AdSense. When ads are shown, third-party vendors, including Google, use cookies to serve ads based on your previous visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the internet. You can opt out of personalized advertising in Google's Ads Settings.

6. Your choices and requests

You can block or delete cookies in your browser settings. To ask what information we hold about you from a contact form message, or to have it deleted, email smartfinanceshub@gmail.com.

7. Changes to this policy

If this policy changes, we'll update it here and change the date at the top.
