hs-cookie-choice | remembers your answer to the cookie card | until you clear it |
cm-rig | a random id for your rig on the map | until you clear it |
cm-account, cm-burner-key | your payout address, and the key of the address generated in your browser | until you clear it |
cm-d-*, cm-ctr-* | today's share difficulty and how far the miner searched, so it never repeats work | until you clear it |
Your wallet extension may store its own data; that is governed by its own policy.
