Symcremental is a free idle game. This page explains what data the game keeps and why.
Saves on your device
Your progress and settings are stored in your browser's local storage (or the app's storage on Android). They stay on your device and are not sent anywhere unless you turn on a cloud save.
Cloud saves with Google sign-in (optional)
On the website you can sign in with Google to keep your progress across devices. When you do, we receive the basic profile Google shares with sign-in (your account ID, name and email address). We store only:
- your Google account ID, a number that identifies your account to us;
- your game save; and
- a sign-in session for each device you use.
Your name is shown only on your own device and your email address is never stored. This data is kept on Cloudflare's servers (Cloudflare Pages and D1) and is used only to sync your game. It is not sold, shared or used for advertising.
To remove it, open Settings → Cloud save → Delete cloud save. That deletes your save and signs you out on every device. Signing out alone keeps the cloud save for next time.
Android app: ads and purchases
The Android app can show optional rewarded ads through Google AdMob and sells an optional boost through Google Play. Google may collect device identifiers and usage data for these services under the Google Privacy Policy. The app lets you review ad privacy choices in Settings. Purchases are handled by Google Play; we never see your payment details.
Hosting
The website is hosted by Cloudflare, which may process basic request data (such as IP addresses) to deliver and protect the site. The game itself does not use analytics or tracking cookies.
Children
The game is not directed at children under 13, and cloud saves require a Google account.
