The short version
Kvant does not collect your files, keys, or wallet addresses. Files and keys are never sent to us or to anyone else, and we keep nothing about you on a server. Encryption happens entirely in your browser. We take privacy seriously, it is the entire point of the product.
What we do not collect
- File contents, filenames, or file metadata
- Encryption keys or key material of any kind
- Wallet addresses or on-chain identity
- Decrypted data
- IP addresses linked to any of the above
Stored in your browser
A few small records live in your browser's local storage and never leave your device: today's count of file encryptions, used for the tier limit; for each wallet address that passed the first-use signing check on this device, a flag saying so; and the wallet connection the wallet library keeps so it can reconnect. No signature and no key is ever stored. Clearing this site's data removes them all.
Analytics
We may use privacy-first analytics (such as Plausible) to understand aggregate page traffic: number of visitors, popular pages, referral sources. These tools collect no personally identifiable information and use no cookies. Wallet addresses are never included in any analytics event.
Blockchain reads
Once the $KVANT token is live, connecting a wallet makes the app read your token balance via a Robinhood Chain RPC endpoint to determine your tier. This read is unauthenticated and is identical to querying any block explorer: the RPC endpoint sees the address it is asked about. No wallet address is stored by us. Pages you visit without connecting a wallet send nothing to the chain.
Third-party services
The application is served by a web hosting provider. Your browser may transmit standard HTTP headers (including IP address) to the provider's infrastructure as part of normal web traffic. Refer to the provider's privacy policy for details.
Changes
We may update this policy. Continued use of the Service after changes constitutes acceptance of the updated policy.
