Privacy policy

Short version: the calculators run in your browser, and we don't ask for your name, email or other personal details. Like most free websites, we use analytics and show ads from services that may use cookies, explained below.

What the calculators do with your numbers

Everything you type into a calculator is processed in your own browser and is not sent to us.

What's saved on your device

To save you retyping, some things are kept in your browser's local storage, on your device only:

• The numbers you last entered in each calculator. Press Reset on a calculator to clear them.
• If you use the quote builder: your business name, contact details, logo, quote notes and your usual tax and deposit percentages.
• Which boxes you've ticked on a checklist guide.

None of this is sent to us. You can remove all of it at any time by clearing your browser's site data.

Share links

If you press Share link, the link contains the numbers entered in that calculator, so whoever opens it sees the same estimate. It doesn't include your business details or logo. Only share it with people you're happy to show those numbers to.

Advertising

To keep the site free, we show ads, or may show ads, served by Google and other advertising partners. These companies may use cookies, web beacons, IP addresses and similar technologies to show ads, limit how often you see them, measure how they perform and prevent fraud.

• Google, as a third-party vendor, uses cookies to serve ads on this site. Google's use of advertising cookies lets it and its partners serve ads to you based on your visits to this site and other sites on the internet.
• You can opt out of personalized advertising from Google in Google's Ads Settings. You can opt out of many other vendors' personalized ads at aboutads.info.
• To learn how Google uses information from sites that use its services, see How Google uses information from sites or apps that use our services.

Where the law requires it, for example for visitors in the European Economic Area, the UK and Switzerland, we'll ask for your consent before personalized ads or non-essential cookies are used, and you can change your choice at any time.

Analytics

We use analytics tools to count visits and see which pages and calculators are useful. We use Cloudflare Web Analytics, which doesn't use cookies or track you across other websites. We may also use Google Analytics, which uses cookies to collect information such as the pages you visit, how long you stay, your general location (city or country level) and your device and browser type. We use this information in aggregate only, to improve the site. You can opt out of Google Analytics with the Google Analytics opt-out browser add-on.

Managing cookies

Most browsers let you block or delete cookies in their settings. If you block cookies, the calculators still work, though you may see less relevant ads.

Your privacy rights

Depending on where you live, including California and other US states, the EU and the UK, you may have the right to know what personal information is collected about you, to ask for it to be deleted, and to opt out of the "sale" or "sharing" of personal information for targeted advertising. We don't sell personal information for money. To opt out of personalized ads, use the links in the Advertising section above, or contact us and we'll help.

What we don't do

• We don't have user accounts.
• We don't ask for your name, email or phone number to use the calculators.
• We don't sell your personal information.

Our hosting provider

Like any website, our hosting and security providers may keep standard server logs, such as IP address, browser type and pages requested, for security and reliability.

Links to other websites

Some pages link to other websites, such as the sources we cite. If you click through, that website's own privacy policy applies.

Children

This site is intended for adults running or hiring home-service businesses and is not directed at children under 13. We don't knowingly collect information from children.

Changes

We'll update this page when we change how information is handled, and change the "Last updated" date above.
