Private by design

Track without connecting a wallet.

Manual tracker data stays in this browser's local storage. There is no account, seed phrase, private key, or exchange login. Optional public-address lookups are clearly labeled and sent to mempool.space only when you use them.

Common questions

Frequently asked questions

Does Stack2One connect to my Bitcoin wallet?

No. Manual tracking needs no wallet data. An optional watch-only tool can look up a public Bitcoin address through mempool.space, but Stack2One never asks for a seed phrase, private key, exchange login, or account.

Where is my tracker information stored?

Tracker information is stored in localStorage in your current browser. It is not synced to a Stack2One account or sent to a Stack2One database.

Does Stack2One buy or hold Bitcoin?

No. Stack2One is an educational planning and tracking tool. It does not execute transactions, hold funds, or provide investment advice.

Can I track a goal smaller than one Bitcoin?

Yes. Choose any positive BTC target, including common milestones such as 0.01, 0.1, 0.21, or 0.5 BTC.
