The short version
Holo has no accounts and doesn't ask for your name or email. Your card collection is stored only in your own browser. The site is paid for by ads from Google, which use cookies, and in the EU and UK they only do that after you agree.
Who runs Holo
Holo is run by Valer Roman. Questions about this page: pullaholo@gmail.com or @pullaholo on Instagram.
What's stored on your device
- Your binder (the cards you've pulled) is saved in your browser's local storage so it's there tomorrow. It never leaves your device, and clearing your browser data deletes it.
- A random player ID (a string of letters and numbers, not linked to you) and your sound and how-to-play settings.
Answer statistics
To show how rare each card is ("pulled by 3% of players"), Holo sends the answers you pull to our server together with that random ID, so each player is counted once per answer. Answers the game doesn't recognise are also collected, so we can add missing ones. We don't store your name, email or IP address with these, and they're only used to run the game.
Advertising
Holo shows ads from Google AdSense. Google and its partners may use cookies and similar technologies to show ads and measure them, including ads based on your interests if you agree. You can read how Google uses information from sites that use its services and adjust personalised ads in Google Ad Settings.
If you're in the European Economic Area, the UK or Switzerland, you'll be asked for consent before any non-essential cookies are used. Change your consent choices.
Our hosting provider
Holo is hosted by Vercel, and its answer statistics are stored with Upstash. Like any website, the host receives standard technical information when you load a page, such as your IP address and browser type, to deliver the site and keep it secure. The statistics database only receives the answers described above and the random player ID.
Visitor counts
We use Vercel Web Analytics to see how many people visit and which sites or posts they came from. It uses no cookies and stores nothing on your device; visitors are counted with a short-lived anonymous value that is discarded after 24 hours, and no data identifies you personally.
Children
Holo is not directed at children under 13 and we don't knowingly collect information from them.
Your rights
Depending on where you live, you may have the right to access, correct or delete personal data and to object to its use. Since Holo itself holds no personal data about you, most requests concern Google's advertising. Use the consent link above or Google's settings, or contact us at the address above.
