Privacy Policy
Last updated: 5 October 2026
Short version
We do not ask for your name, email address or any other personal detail, and there is no account to create.
Your best streak is stored in your own browser and never leaves your device.
What is stored on your device
The game saves your best streak using your browser local storage. This stays on your device, is readable only
by this site, and can be removed at any time by clearing your browser data. It contains a single number.
What we receive
- Standard server logs. Like any website, our server records the IP address, time, requested
page, referring page and browser user-agent string of incoming requests. These are used to operate and
secure the service.
- Anonymous usage events. To understand whether the game works well, the page sends simple
events such as page opened, round started, and how long the page stayed visible. These are not linked to a
name, an email address or any account, because none exists.
- Campaign parameters. If you arrived via an advertisement, the link may contain identifiers
placed by the advertising network. These are recorded with the usage events so we can tell which traffic
source a visit came from.
What we do not do
- We do not sell or rent any data.
- We do not ask for or store payment details, because there are no payments.
- We do not send push notifications and do not ask for permission to.
- We do not use third-party advertising or tracking scripts inside the game.
Third parties
Price data is read from a public market data feed. Your browser does not contact the data provider directly:
the request is made by our own server, so the provider does not receive your IP address.
Retention
Server logs and usage events are kept only as long as needed to operate and improve the service, and are
deleted or aggregated thereafter.
Your choices
Clearing your browser site data removes the stored best streak. You can block the usage events with any
standard content blocker and the game will continue to work.
