Privacy Policy
Effective date: June 25, 2026
1. Introduction
Claak is a self-custodial cryptocurrency wallet that runs as a browser extension. This policy describes what data the wallet handles and where it goes. In short, your keys and funds stay on your device, and we (the publisher) receive nothing about your use of the wallet.
2. What We Collect
Nothing.
The Claak wallet has no server of its own, no analytics, no telemetry, and no user accounts. We do not collect, store, or transmit any personal data from your use of the wallet.
3. What Stays on Your Device
- Your recovery phrase and keys are generated locally and stored only on your device, encrypted with your password (in the browser's extension storage). They are never transmitted anywhere.
- Settings, account list, nicknames, connection records, and your transaction cache live in local extension storage.
- The unlocked session key lives in session storage and is erased when the browser closes.
- Optional biometric unlock uses your operating system's WebAuthn (Touch ID or Windows Hello). Biometric data never leaves your OS and is not accessible to the wallet.
4. What Third Parties Necessarily See
Like every wallet, Claak talks to public blockchain infrastructure to show your balances and broadcast the transactions you choose to send:
- RPC providers for each chain (Alchemy as primary; publicnode, the Solana Foundation, and Bitcoin Esplora endpoints such as mutinynet and mempool.space as fallbacks) receive your IP address and the blockchain addresses or transactions you query or broadcast, governed by their own privacy policies. This includes Alchemy's token and NFT balance APIs, used to detect assets when migrating an older account. Blockchain transactions themselves are public by design.
- Name resolvers (eth.llamarpc.com for ENS, the Bonfida proxy for SNS) see the name you ask to resolve and your IP address, only when you enter one.
- TrustWallet assets CDN serves token logo images and sees your IP address (standard for any image CDN). If it is unavailable, built-in icons are used instead.
No other parties receive anything.
5. Data Sales and Sharing
We do not sell, share, or monetize any user data. There is none to sell.
6. Changes
We may update this policy from time to time. Changes will be published at this URL with an updated effective date.
