Privacy Policy

Play without signing up

There’s no account to create before you play. You don’t need to give us an email address or password.

The games currently have no advertising, analytics or tools that track how you play.

Your game progress stays on your device

Nicknames, daily play counts, collections, and your sound and language settings are saved in your browser. The game doesn’t send these records to us.

We also keep a previous save on your device in case your progress becomes unreadable. If you use the recovery feature, a copy of the unreadable data stays on that device too.

When you want to remove your records

You can remove a player through the PARENTS settings.

To remove all records for this site, including backup and recovery copies, clear this site’s stored data in your browser settings.

Clearing that data, switching browsers or opening the games at a different website address may mean your earlier progress is no longer available. Progress doesn’t automatically carry over to another device.

If you download a recovery file, please keep it private. It may contain player nicknames.

When you get in touch

The name you choose to provide, your reply email address and your message are delivered to our support inbox. We use this information to help with your inquiry.

Cloudflare hosts the website. To help prevent spam and misuse of the contact form, Cloudflare Turnstile and Cloudflare Worker process technical information such as your IP address and browser details. Google Apps Script delivers the message to our inbox.

We keep correspondence only for as long as needed to provide support and meet applicable obligations. If you’d like us to delete your correspondence, please ask through the contact form. Your messages aren’t saved in your browser as part of your game records.

If you choose to support the games

Support payments are optional and for adults only. When you choose an amount, you’ll go to a Stripe-hosted checkout page.

This website doesn’t collect your card number or security code. Stripe handles payment details, contact information and technical information under its Privacy Policy.

We receive the transaction records, contact details and payment-status information that Stripe makes available to us. We use these to manage payments, help with payment questions and meet accounting and legal obligations. We keep them for as long as needed for those purposes.

We don’t link your payment to a player’s nickname or collection.

You’re welcome to contact us with privacy requests. Some transaction records may need to be kept to meet legal obligations.
