Privacy Policy

Privacy Policy Overview

This policy describes the privacy practices of Forbole Technology Limited (“Forbole”, “we” or “us”) with respect to (a) the Forbole website located at forbole.com (the “Platform”) and (b) applications and interfaces offered by Forbole, including the Kastle wallet (“Kastle” or the “Service”) (collectively, the “Products”).

1. About Us

Forbole Technology Limited is incorporated in Hong Kong (Company No. 3282304). We provide non-custodial tools, meaning we never have access to your private keys or the ability to move your funds.

2. Personal Information We Collect

2.1 Public On-Chain Data. By design, blockchain transactions are public. We collect and display public data (wallet addresses, transaction hashes, and balances) to provide the Service.

Note: Once broadcast to a blockchain, this data is immutable and cannot be deleted or altered by Forbole.

2.2 Automatically Collected Data (RPC & Nodes). When your Wallet interacts with the blockchain, it connects to an Remote Procedure Call (RPC) node. This node inherently receives your IP Address and your Wallet Address to broadcast transactions or fetch balances. While Forbole does not use this data to identify you personally, it is technically processed during your session.

2.3 Swap & Bridge Interaction Data. If you use the Swap or Bridge features:

  • Transmitted Data: We transmit your wallet address, token types, and amounts to third-party DEX aggregators (e.g., 1inch, Jupiter) or bridge protocols.
  • Third-Party Processing: These providers process your IP address and transaction data according to their own policies. Forbole does not control these third parties.

2.4 Product Analytics (PostHog). We use PostHog, a product analytics service operated by PostHog Inc., to understand how the Service is used and to improve it. Our PostHog instance is hosted on PostHog's EU Cloud infrastructure.

  • What we collect: anonymous event data describing in-app actions (for example: wallet creation, send, bridge, and swap completions, including outcome and the token type, chain ID, and contract addresses involved); an anonymous device-level identifier randomly generated by the PostHog SDK on first launch; the application version and operating system; and approximate (country-level) location derived from your IP address at the time of ingestion.
  • What we do not collect via analytics: your IP address is masked at the SDK level and is not stored; we do not transmit your wallet addresses, private keys, seed phrases, transaction amounts, balances, or transaction hashes through our analytics pipeline. (As noted in section 2.1, on-chain transaction data remains public on the blockchain itself, independent of our analytics.)
  • Purpose: product analytics only. We do not use this data for advertising, for tracking you across other apps or websites, or for sharing with third parties beyond PostHog acting as our data processor.
  • Your control: you can opt out of analytics collection at any time in Settings → Data & Privacy → Share Anonymous Analytics. When opted out, the PostHog SDK stops sending events immediately, and your choice is remembered on your device.
  • A full list of analytics events collected by Kastle is available on request via privacy@forbole.com.

3. How We Use Information

We use your data to:

  • Operate and maintain the Kastle Wallet and RPC infrastructure.
  • Provide customer support and respond to technical inquiries.
  • Prevent fraud and investigate security breaches or malicious "dusting" attacks.
  • Comply with legal obligations under the laws of the Hong Kong SAR.

4. How We Share Information

4.1 No Sale of Data. We do not sell your personal information.

4.2 Third-Party Providers. We share necessary data with:

  • DEX Aggregators & Liquidity Providers: To fetch quotes and execute swaps.
  • Bridge Operators: To facilitate L1/L2 asset transfers.
  • Cloud Infrastructure: For hosting our website and RPC nodes.
  • Product Analytics: PostHog Inc., as a data processor, hosting our analytics on PostHog EU Cloud.

5. Your Choices and Rights

5.1 Access and Rectification. You may request access to or correction of any off-chain personal data we hold (e.g., support emails) by contacting privacy@forbole.com.

5.2 The Right to Erasure (Important). You may request that we delete your off-chain data. However, we cannot delete, "un-publish," or mask any data stored on a blockchain (such as the Kaspa ledger). Your transaction history is permanent.

5.3 Opt-Out. You can opt out of product analytics at any time in Settings → Data & Privacy → Share Anonymous Analytics. To stop all other data processing associated with the Service (including connections to RPC nodes and third-party DEX/bridge providers when transacting), discontinue use of the Wallet and delete the application from your device. Note that on-chain data already broadcast to a blockchain remains public and cannot be removed by Forbole (see section 5.2).

5.4 Analytics Data Deletion. You may request deletion of historical analytics data associated with your device by contacting support@kastle.cc. Because the analytics data is keyed to an anonymous device identifier rather than to your identity, we may ask you to provide additional information to help us locate the relevant records. Requests are processed within 30 days. To prevent any future analytics collection, use the in-app opt-out described in section 5.3.

6. Data Security and Retention

We employ industry-standard encryption and TLS protocols for RPC traffic. We retain off-chain personal data only for as long as necessary to fulfill support or legal requirements.

7. Global Transfers

As a Hong Kong-based company, we process data globally. By using the Services, you acknowledge that your information may be transferred to and processed in jurisdictions that may have different data protection laws than your own.

Specifically, our product analytics data (see section 2.4) is processed by PostHog Inc. on infrastructure located in the European Union.
