What we do not collect
- No account, email address or name is required or requested.
- No analytics, advertising or tracking scripts, and no third-party scripts of any kind. Fonts and images are served from this site.
- No cookies are set by this site.
- Passwords and Quantum Safe keys are never sent to a server. A day key is handled in your browser; a recovery kit is handled only in the offline tool and never by this site.
What leaves your browser
- Page requests. The site is hosted on Vercel, which processes your IP address and browser details to deliver pages and keeps operational logs under its own policy.
- Solana reads. When you connect a wallet or use the wallet check, the public address and the request are passed through this site’s server to a Solana RPC provider, which can see the address being queried. Wallet addresses and balances are public on the Solana network.
- Links you follow to GitHub, X or a block explorer are governed by those services.
The Quantum Safe Watch browser extension
Quantum Safe Watch collects nothing and sends nothing to us. It has no account, no analytics and no server of ours behind it.
- What it keeps, in your browser only: the Quantum Safe addresses you choose to watch, the last public state it read for each, a short list of recent alerts, and the RPC address if you set your own. Removing the extension removes all of it.
- What leaves your computer: requests to one Solana RPC endpoint, the public mainnet one or the one you set, asking for the accounts you watch or check. That provider can see those addresses and your network address, as with any use of Solana.
- What it never has: a key, a seed phrase, a recovery kit, a password or a wallet connection. It cannot read or change any web page.
What is stored on your device
When you open a Quantum Safe on this site, the app keeps a record in this browser’s local storage of which one-time keys it has used and of a signed withdrawal that has not been announced yet, so that an interrupted one can be resumed. If you choose passkey unlock, an encrypted copy of your day key is stored there too. Clearing site data removes them. The site’s servers store none of it.
Telegram alerts
Alerts are optional. If you turn them on for a Quantum Safe, the site stores your Telegram chat ID and the address of each Quantum Safe you watch, so it can message you when something happens there. It stores no keys and no wallet address. Telegram, which delivers the messages, knows the same. Send /stop to the bot and the record is deleted. Alerts can be late or missing; silence is not proof that nothing happened.
The wallet check
The address you paste is used for that lookup and is not stored by this site. If you copy a result link, the address is part of the link.
Changes and contact
This page describes the public beta and will be updated when anything it describes changes, including any alert service that needs a contact address. The site’s source is public, so each claim here can be checked against the code. Questions: @QsafeModeIO or a GitHub issue.
