Privacy Policy

Last updated: July 28, 2026

This is a plain-language starting template, not a substitute for legal advice — consider having it reviewed (e.g. via Termly, iubenda, or a lawyer) as the site grows, particularly if you expand into features that collect more personal data.

What this site does

WorldTip is a tip calculator and currency converter, with an optional paid Trip Pass / Lifetime archive feature for logging trip expenses. The free calculator runs entirely in your browser — the amounts you type in are never sent to us or stored on any server we control.

Information we collect

Using the free calculator doesn't require an account, and we don't collect names, emails, or payment information through normal use of it.

If you purchase a Trip Pass or Lifetime plan, we collect the email address associated with your purchase and your subscription status (plan type, active/expired), stored via Supabase, our database provider. Payment itself is handled entirely by Stripe — we never see or store your card details. If you use the trip archive feature, the trips, expense entries, and any receipt photos you choose to save are stored in your account via Supabase, and are only accessible to you.

If you email us via the Contact page, we'll have whatever information you choose to include in that message.

Cookies and advertising

This site uses Google AdSense to display ads. Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to this or other websites. You can learn more about how Google uses this data at policies.google.com/technologies/partner-sites, and manage your ad personalization settings at adssettings.google.com.

If you're visiting from the EEA or UK, you'll be shown a consent message before any ad personalization cookies are set, letting you choose whether to allow personalized ads or opt for non-personalized ads instead. You can change your choice at any time by clearing your cookies for this site and revisiting, which will show the message again.

Currency data

Live exchange rates are requested from the Frankfurter API on page load. This request does not include any personal information — only a generic request for current rates.

Analytics

We use Cloudflare Web Analytics to understand overall traffic (e.g. which pages are popular). It's designed to be privacy-respecting — it doesn't use cookies or any persistent client-side identifiers to track you, and doesn't collect personal information. You can read more about how it works at cloudflare.com/web-analytics.

Children's privacy

This site is not directed at children under 13 and we do not knowingly collect information from them.

Changes to this policy

We may update this policy as the site evolves. Material changes will be reflected by updating the date at the top of this page.
