Your Account

Optional

Every tool on this site works without an account — your progress saves to the browser you are using. Sign in and it follows you to your phone, your tablet and any other browser, and your alliance space comes with it.

What an account does

What it stores: your email address, and the progress you create in the tools (research nodes ticked, wrench counts, planner layouts, and similar). Nothing else.
What it never stores: passwords (there aren't any — sign-in is a one-time emailed code), payment details, or your in-game account credentials.
It stays optional. Every tool works exactly the same without one; progress simply stays on the one device.
One sign-in covers both. The same account reaches your alliance space, if you belong to one — there is no second login to remember.
You can leave at any time. Export your data as JSON, or delete it outright.

See the Privacy Policy for the full detail, including the lawful basis and how long data is kept.
