Short version: the calculator runs locally, saved plans and a few preferences stay on your device, and the site uses ads and basic traffic analytics.
Last updated: March 28, 2026.
If you choose to save your plan, the calculator stores it locally in your browser so you can return later. We also store a small amount of site preference data locally, such as your selected currency and whether you have already dismissed certain prompts.
This locally stored data stays on your device unless you choose to share it. At this time, we do not use first-party cookies for calculator accounts or logins.

We use Google AdSense to show ads. Depending on your location, settings, and the consent choices presented to you, Google may limit or expand the use of cookies and personal data for ad personalization and measurement.
Even in this setup, Google or its partners may receive technical data needed to deliver ads, such as your IP address, browser information, device information, and basic request data. Google may also use cookies or similar technologies for personalized ads or measurement, subject to your choices and applicable law.
Google acts as a separate provider for its advertising services and may process data under its own terms and policies.
We currently use Cloudflare Web Analytics to understand overall traffic and improve the site. This is intended to provide aggregated usage information rather than detailed profiling of individual visitors.
Where applicable under privacy law, we process data to provide the site, keep it secure, respond to messages you send us, and operate advertising features. Depending on the situation, this may be based on our legitimate interests, your consent, or the need to respond to your request.
Recipients may include hosting, infrastructure, and advertising providers involved in operating the site.
Calculator plans and preferences stored in your browser remain there until you clear them or your browser removes them. If you contact us by email, we keep your message for as long as needed to handle your request and any related follow-up.
Some third-party providers, including Google, may process data outside your country, including in the United States, subject to their own legal safeguards and documentation.
If you are in the EU/EEA/UK, you can request access, correction, deletion, objection, and data portability where applicable.
Contact us to exercise these rights. We will verify your request and respond within legal timeframes.
You may also have the right to withdraw consent at any time where consent is the legal basis for processing, and to lodge a complaint with your local data protection authority.
