Privacy Policy

1. Overview

Sentel ("we", "our", or "us") operates a non-custodial on-chain application on the Solana blockchain. This Privacy Policy explains what information we collect when you use the Sentel interface at sentel.xyz (the "Interface"), how we use it, and your rights.

Because Sentel is a non-custodial protocol, we do not hold your private keys, control your assets, or have the ability to reverse transactions. All on-chain activity is public and permanent by design.

2. Information we collect

Sentel has no backend, no database, and no user accounts. There is no sign-up, no login, and no form that asks for your name, email address, phone number, or any personal identifier. We cannot collect what we never ask for.

The only data that flows through your use of the Interface is:

• Wallet public keys. When you connect a wallet, your public key is read client-side to display your vaults and balances. It is never sent to or stored on a Sentel server — because no such server exists.
• Hosting logs. Standard access logs (IP address, browser type, pages visited, timestamps) may be retained by our hosting provider (Vercel) for uptime monitoring and abuse prevention. This data is governed by Vercel's privacy policy and is not sold or shared by us.
• RPC requests. Transactions and balance queries are sent directly from your browser to Solana RPC providers. These providers may log request metadata in accordance with their own privacy policies.
• Price queries. Token price requests are sent to third-party price APIs and contain only token mint addresses — no personal information of any kind.

3. On-chain data

All transactions you sign and submit through the Interface are recorded on the Solana blockchain. Blockchain data is public, immutable, and outside the control of Sentel. We cannot delete or modify on-chain records.

4. Cookies and local storage

The Interface may use browser local storage to remember UI preferences (such as theme or recently viewed vaults). No tracking cookies or advertising pixels are used.

5. Third-party services

The Interface integrates with the following third-party services:

• Jupiter Aggregator for swap routing. Swap requests include token mints and amounts.
• Solana RPC providers for blockchain data. Requests include public keys and transaction data.
• Vercel for hosting. Standard access logs are retained per Vercel's privacy policy.
• Vercel Speed Insights for performance monitoring. This tool collects anonymised, aggregated page-performance metrics (e.g. Core Web Vitals such as LCP, FID, and CLS) directly in your browser. No personal identifiers are collected. Data is processed by Vercel in accordance with their privacy policy at vercel.com/legal/privacy-policy.

We do not control how these third parties handle data. We encourage you to review their privacy policies.

6. Performance analytics

We use Vercel Speed Insights, a browser-based performance monitoring tool, to measure how fast pages load for real users. The tool captures Core Web Vitals (Largest Contentful Paint, First Input Delay, Cumulative Layout Shift, and related metrics) and reports them to Vercel.

Speed Insights does not use cookies, does not fingerprint your device, and does not collect personally identifiable information. The data collected is anonymous and aggregated; it is used solely to improve the performance of the Interface.

If you prefer not to have performance data collected, you may disable JavaScript or use a content blocker — this will prevent Speed Insights from running.

7. Data retention

We do not operate a database of user data. Server access logs retained by our hosting provider are governed by that provider's retention policy. On-chain data is retained indefinitely on the Solana blockchain.

8. Your rights

Depending on your jurisdiction you may have rights regarding your personal data, including the right to access, correct, or request deletion of any data we hold about you. Because we hold no personal data beyond standard server logs, most requests can be addressed by simply not using the Interface.

If you have a specific data request, please contact us using the details below.

9. Changes to this policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page will reflect any changes. Continued use of the Interface after changes constitutes acceptance.
