Our Privacy Commitments
1) Information We Collect
Usage data: anonymous or aggregated information such as pages visited, calculator features used, and basic device information.
Optional contact data: if you contact us (e.g., support email), we receive your message and any provided contact details.
2) How We Use Information
To operate the website, improve calculator accuracy and usability, monitor performance, prevent abuse, and respond to your inquiries.
3) Cookies & Similar Technologies
We use essential cookies for site functionality and analytics cookies to understand aggregate usage. In addition, third-party vendors — including Google — use cookies to serve and personalize ads. You can control or block cookies through your browser settings, and manage ad personalization using the opt-out links in section 4.
4) Third-Party Services, Advertising & Analytics
To operate the site, serve ads, and understand how the calculators are used, we rely on the following third-party services, each governed by its own privacy policy:
- Google AdSense — displays advertising on the site.
- Google Analytics (GA4) — measures traffic and usage.
- Vercel Analytics and Vercel Speed Insights — measure aggregate traffic and page-performance metrics.
- Ahrefs Analytics — privacy-friendly, aggregate traffic measurement.
Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and 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 may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of a third-party vendor’s use of cookies for personalized advertising at aboutads.info/choices and optout.networkadvertising.org. Blocking these cookies does not stop ads from showing — it only makes them less relevant.
5) Data Retention
We keep data only as long as needed to provide and improve the service or comply with legal obligations, then delete or anonymize it.
6) Security
No method is 100% secure, but we implement reasonable safeguards to protect information in transit and at rest.
7) Children’s Privacy
Our calculators are intended for general audiences and are not directed to children under 13. We do not knowingly collect data from children.
8) Your Choices & Rights
You can disable non-essential cookies in your browser. If you contact us about your information, we will reasonably assist with access, correction, or deletion requests where applicable.
9) Changes to This Policy
We may update this policy to reflect improvements or legal requirements. Material changes will be noted by updating the date above.
