Yeastimate is a small daily game. We collect as little as possible, and none of it identifies you as a person.
What stays on your device
Your scores, streak, calendar, unlocked breads and settings are saved in your browser’s local storage. They never leave your device unless you use the online features below.
What we store online
- An anonymous player ID. Created automatically so the leaderboard knows which scores are yours. It is not linked to your name, email or phone.
- Your nickname, bread and accessory. Shown publicly on the Hall of Flame.
- Your daily results. Each slice’s points and guesses for your last 14 daily games, plus your all-time total and best score.
- Crumb Clubs. If you start or join a club, its name and the anonymous IDs of its members are stored so the club can show a shared scoreboard. Members see each other’s nickname and daily scores.
- Toast-Off rooms. While you’re in a Toast-Off, your nickname, answers and lives are shared with the other players in that room. This is removed as soon as you leave or close the page.
- If you create an account (optional): your email address and either a securely hashed password or your Google sign-in (we receive your name, email and profile picture link from Google but only use the email), handled by Google Firebase Authentication, plus a private copy of your game progress so you can play on any device. Only you can read it. We use your email only to sign you in and to send password reset emails you ask for.
You can play without an account. We don’t ask for your real name, location or contacts, and nicknames are filtered to keep them friendly.
Where it lives
Online data is stored with Google Firebase in the UK (London) and the EU (Belgium). The website is hosted by Cloudflare. Both act as our service providers.
Cookies and tracking
No advertising, no tracking cookies and no cross-site tracking. We may count visits with Cloudflare Web Analytics, which doesn’t use cookies or identify you.
Delete your data
Open the Bread Bin (your toast in the top corner) and tap Delete at the bottom. That removes your leaderboard entry, your club memberships and everything saved on your device, and if you have an account, your account and its saved progress too. You can also email us and we’ll delete it for you.
Leaderboard entries only keep your last 14 daily games.
Why we use it
Only to run the game: the leaderboard, streaks, clubs, accounts and multiplayer. The legal basis is our legitimate interest in providing the game you chose to play, and for accounts, providing the account you asked for. We never sell your data, share it for marketing or send you marketing emails.
Your rights
Under UK GDPR you can ask to see, correct or delete your data, or object to how we use it. If you’re unhappy with how we handle it, you can complain to the Information Commissioner’s Office (ico.org.uk).
