Privacy policy

What we collect

The calculators run entirely in your browser. The numbers you type are not sent to us or stored on our servers. There are no accounts, forms or newsletters on this site.

Local storage

The Pokemon card collection tracker saves your list in your own browser's localStorage so it is there next time. It never leaves your device; you can delete it with the "Clear all" button or by clearing site data.

Hosting logs

The site is hosted on Cloudflare Pages. Like any web host, Cloudflare may process technical data such as IP addresses to deliver and protect the site, under Cloudflare's privacy policy.

Advertising and cookies

The site does not currently use advertising or tracking cookies. If advertising (for example Google AdSense) is added later, third-party vendors including Google may use cookies to serve ads based on your visits to this and other websites. You will be able to opt out of personalised advertising at Google Ads Settings or aboutads.info, and this policy will be updated before any such change.

External links

Links to other websites (government sources, platforms, related services) are governed by those sites' own privacy policies.

Because we do not collect personal data through the calculators, there is nothing to access or correct. Any future feature that collects personal data will ask for your consent first.
