Privacy notice

Version beta-2026-08-18 · Effective 18 August 2026

This notice describes how Jerno handles personal information during the private beta. It applies to the public website, cloud workspace and supported broker-integration pilots.

1. Who is responsible

The current product operator is Jerno private beta. Registered business address: Business details will be confirmed before public launch. Privacy enquiries can be sent to the privacy contact.

2. Information we collect

Depending on the features you use, we may process account details, profile preferences, original audio, transcripts, confirmed trade details, chart snapshots, playbook reviews, notification subscriptions, support conversations, broker account labels and broker-confirmed executions. If you deliberately attach safe technical details to an in-app support conversation, the snapshot is limited to the Jerno release, general page, browser and operating-system family, device class, workspace mode, broker provider and connection health, and capture time. It excludes raw browser strings, IP addresses, broker logins, account identifiers, trade identifiers, journal content and credentials. Demo workspace information remains in that browser unless you deliberately export it.

3. Why we use it

We use this information to authenticate accounts, operate the journal, process recordings you submit, link broker evidence, deliver requested notifications, calculate analytics, protect the service and respond to support enquiries. Before public launch, the final notice will identify the applicable lawful bases for each purpose.

4. Audio and AI processing

When production AI is configured and you choose to process a recording, audio is sent server-side to OpenAI for transcription. The transcript may then be processed to suggest structured trade fields. Suggestions remain editable and the original recording is preserved separately where available. Secret API keys are never sent to the browser.

5. Broker connections and notifications

Supported read-only connections may provide account labels and confirmed execution details needed to prepare journal prompts and reconcile outcomes. Jerno does not use these connections to place, modify or cancel orders. Enabling notifications stores an encrypted device push subscription, which you can remove in Settings.

6. Service providers

The beta may use Supabase for authentication, database and protected media storage; OpenAI for selected transcription and extraction; configured market-data providers for chart context; and web-push infrastructure for notifications. The final notice will list confirmed processors, locations and contractual safeguards.

7. Retention

Journal records and authenticated in-app support conversations are retained while your account remains active. In-app support messages and their optional diagnostic snapshots are included in your account export and deleted when you delete the account. Guest enquiries are retained only while needed to answer, manage and evidence the support request, then reviewed for deletion. Operational security records and infrastructure backups may follow separate limited retention periods that will be confirmed before public launch.

8. Support diagnostics and optional repairs

Your journal reasoning remains private by default. You may explicitly allow authorised Jerno owners or administrators to find relevant entries and open one entry's written reasoning with its instrument, note type and recorded time while diagnosing your account. Each request requires a recorded support reason and is written to a protected access log. You may separately permit limited corrections to written reasoning or the Live, Paper or Practice classification. Every such repair is audited, retains its previous value and can be restored. Neither permission includes recordings, raw transcripts, charts, broker credentials, notification endpoints, execution prices or broker-confirmed P&L.

9. Your choices and rights

You can correct extracted fields, delete recordings separately, export journal information and authenticated support conversations, delete entries, disable notifications, choose whether a support conversation includes safe technical details, independently enable or revoke journal diagnostic and repair permissions, or request account deletion from Settings. Starting a support conversation never enables journal diagnostic or repair access. Depending on where you live, you may also have rights to access, correct, erase, restrict or object to processing and to receive a portable copy of certain information.

10. Security and international processing

Production media buckets are private and accessed using short-lived signed links. Sensitive credentials remain server-side. Some providers may process information outside the United Kingdom; the final notice will document relevant transfer safeguards before public launch.

11. Children

Jerno is not designed for children. A final minimum age and eligibility policy will be confirmed before public launch.

12. Changes and complaints

Material changes will be dated on this page. Privacy questions or complaints should first be sent to the Jerno privacy contact; the final notice will also identify the appropriate supervisory authority.

13. Financial disclaimer

Jerno is a journaling and performance-review tool. It does not provide financial advice, predictions or trade recommendations.
