Privacy Policy

1. What the site does not collect

There is no account system. No registration, no sign-in, and no wallet connection is required.

The site sets no cookies and loads no third-party analytics, advertising or tracking scripts.

The account size, entry price, stop price, target price, leverage and every other parameter you enter — together with every record in the trade journal — are never uploaded to any server, including this site's own. All computation happens in your browser.

2. Data stored on your device

So that you need not re-enter everything on your next visit, the site stores a small amount of data in your browser's localStorage. It stays on your device and the site cannot read it remotely:

· hn_calc_prefs — frequently used calculator inputs (account size, risk rate, leverage, fee rate, margin mode)

· hn_trades — all trade journal records

· hn_jprefs — the symbol and direction last used in the journal form

· hn_hl_meta_v1 — cached Hyperliquid contract parameters, valid for 24 hours

Clearing your browser data removes all of the above. The site also provides a "Clear all" button for the journal and an "Export" function that writes your records to a file you keep yourself.

3. The one outbound request

The site sends a single request to Hyperliquid's public API to retrieve the contract list (maximum leverage and size precision for each contract):

POST https://api.hyperliquid.xyz/info with body {"type":"meta"}

The request contains none of your input; it is a fixed query. The response is cached in your browser for 24 hours. If the request fails, the site falls back silently to manual entry and functionality is unaffected.

As with any network request, Hyperliquid's servers will observe your IP address in the process. That is inherent to network communication and cannot be avoided on your behalf.

4. Hosting logs

The site is hosted on Cloudflare. As with every website, the host's servers record standard access logs, typically including IP address, browser identifier, timestamp and the path requested, for security and troubleshooting purposes.

That data is handled by Cloudflare under its own policies. The site's operator does not actively read, analyse or retain those logs, and builds no user profiles from them.

5. Sharing and cross-border transfer

The site collects no personal data, so there is no sale, sharing or cross-border transfer of personal data to speak of.

No information about you will be provided to third parties for any commercial purpose — because the site does not hold any.

6. Children

The site is not directed at minors and does not knowingly collect information from them.

7. Changes to this policy

This policy may be updated as features change. Should any future feature introduce an outbound request or data collection, this page will be revised and the date at the top updated accordingly.
