Straight talk about what we collect and why.

You never need to create an account to use any tool here. We don't ask for your name, your email, or any information that identifies you. There's no sign-up form and no paywall — every tool is free to use, every time.

This site is supported by advertising. We use Google AdSense to display ads on this site. AdSense is run by Google and uses cookies — including the DoubleClick cookie — to show ads that are relevant to you based on your previous browsing activity across websites.

We don't control which ads appear, and we don't receive any of the data Google collects for this purpose. Google's use of advertising cookies is governed by Google's Privacy Policy.

You can opt out of personalised advertising at any time. Two ways to do it:

• Google Ad Settings — Manage how Google uses your data for ad personalisation.
• Network Advertising Initiative opt-out — Opt out of interest-based advertising from NAI member companies.

Every calculation — your mortgage repayments, your BMI, your sleep schedule — happens directly in your browser. There's no server receiving or storing your inputs. We don't log what numbers you type, and we have no way of seeing them. This isn't a marketing claim; there genuinely is no backend.

Separately from ad cookies, a few things are saved in your browser's local storage by the app itself. This data stays on your device and is never sent anywhere:

• ⏱️Recently used tools. Powers the "Jump back in" strip on the home screen.
• 📌Pinned tools. Keeps your favourites at the top of the grid.
• 🌙Dark or light mode preference. So you don't have to set it again each visit.

You can clear this at any time through your browser's settings (look for "clear site data"). Once cleared, the app resets to defaults.

We don't set our own cookies. The only cookies on this site come from Google AdSense. If you opt out of personalised ads using the links above, Google will still show ads but they won't be tailored to your browsing history.

If you're in the EU or EEA, you may see a consent prompt when you first visit, as required by European privacy law (GDPR). Declining personalised ads means you'll still see ads — just generic ones rather than interest-based ones.

The "Tip & Split" tool opens Betale.it in a new tab. Betale is a separate app with its own privacy-first approach. Once you navigate there, you're on their site and their privacy policy applies.

The site is served over HTTPS. Modern browsers require this for PWAs to work, and it means the connection between you and this site is encrypted in transit.

If something here isn't clear, or you want to know something specific, get in touch. This page is meant to be honest and readable, not to bury things in legal language. We'll give you a straight answer.
