Version 2 · Last updated September 23, 2026
Effective date: September 23, 2026
Change on September 23, 2026: the automated safety screen described in the previous version (sections 2 and 8) has been removed. Messages are no longer screened. Nothing else changed.
This Privacy Policy describes how Mechanical Trader LLC ("Mechanical Trader," "we," "us") collects, uses, and protects information in connection with mechanicaltrader.ai and the Mechanical Trader application (the "Service"), including the waitlist and the marketing site.
a. Account information. Your name, email address, password (stored in hashed form by our authentication provider), and the profile and settings you choose. If you join the waitlist, your email address.
b. Content you provide. The Service is built on information you enter: trade records (symbols, direction, executions, stop and target levels and changes to them, setup tags, on-plan designations), notes, journal entries, chart images you attach to trades, your trading rules and setups, and your conversations with the Service's AI coaching features. Coaching conversations may include descriptions of your emotional state as it relates to trading; by using those features you choose to provide that information. Chart images are stored in private storage under your account, location and device metadata is removed from them, and they are never sent to the AI provider. Do not upload or paste content that contains other people's personal information; remove it first.
Journal entries and coaching conversations may contain first-person descriptions of emotion around trading. We collect that content only because you enter it. We use it only to generate coaching and the safety response described in Section 2, we do not use it to infer any diagnosis, we do not sell it or use it for advertising or to train general-purpose AI models, we review it in identifiable form only under the exceptions in Section 2, and we delete it on the same schedule as your conversations.
c. Usage and technical data. Log data such as IP address, browser type, device information, pages viewed, and timestamps, collected to operate and secure the Service; approximate location derived from your IP address (country level, not precise geolocation), used to apply regional availability; and your usage of AI features (message counts and processing cost), used to apply usage limits.
d. Payment information. When paid subscriptions launch, payments will be processed by a payment processor (Stripe). We do not receive or store your full card number. We will receive from Stripe your customer identifier, card brand and last four digits, billing email, invoices, subscription status, and any dispute records.
e. What we do not collect. The Service does not connect to your brokerage account. We never ask for and cannot access your brokerage credentials, positions, or funds. We do not collect data about you from data brokers.
f. Derived records. From the information you provide, the Service computes statistics, records of recurring trading behaviors, and facts extracted from your conversations that the coach uses in later conversations. These are stored with your account, used to provide coaching and for the purposes in Section 2, and deleted as described in Section 5.
We do not sell your personal information. We do not share it for cross-context behavioral advertising. We do not use your data to advertise to you.
Coaching features are powered by a third-party AI provider (Anthropic). To generate a response we send the provider your conversation, your rules and setups, your recent trades and related records, and the derived records described in Section 1(f). We never send chart images, your password, or payment details. The provider processes that data under its standard commercial terms, which prohibit it from using the data to train its models. Under its data retention policy it deletes inputs and outputs within 30 days of receipt, and keeps them longer only where its usage policy or the law requires. We cannot delete data from the provider's systems earlier than that. AI outputs are generated automatically and are stored in your account as Service data.
We share information only with processors needed to run the Service, under agreements limiting their use of it:
Each provider processes your information under its data processing terms. We will update this list when it changes and notify you of a material change.
We may also disclose information if required by law, to protect rights and safety, or in connection with a merger, acquisition, or sale of assets (with notice to you in that event).
We retain your information while your account is active. When you delete your account, your records, conversations, derived records, safety-screen results, and profile are deleted from our production database immediately. Our database provider keeps up to seven days of backups that we cannot edit; deleted data leaves those backups on that schedule. Copies already sent to the AI provider are deleted by the provider within 30 days under its policy, as described in Section 3. Server and security logs are kept for a short period. Billing event records are kept with your account identifier removed; Stripe keeps its own records under its policy and as tax law requires. Waitlist email addresses are kept until launch or until you ask us to remove them.
Depending on your region (for example, the EEA, United Kingdom, or California), you may have additional legal rights, including rights to access, correct, delete, or port your personal information, to object to or restrict certain processing, and to non-discrimination for exercising your rights. To exercise any right, use the in-product controls above or contact us at the address below; we verify requests through your signed-in account or the email address on your account. The Service makes automated assessments (behavior readings and usage limits) that do not produce legal or similarly significant effects; you can ask us to review any of them. If you are in the EEA or UK, our legal bases for processing are performance of our contract with you (providing the Service), our legitimate interests (securing and improving the Service), and your consent where required. You may lodge a complaint with your local supervisory authority.
We use industry-standard measures to protect your information, including encryption in transit, access controls that restrict each account's data to that account, and least-privilege access to production systems. No system is perfectly secure; please use a strong, unique password. Administrative actions on accounts are logged, and administrators can read identifiable conversation content only under the exceptions in Section 2. If a security breach affects your information, we will notify you as required by law.
The Service uses cookies only to keep you signed in. Your display preference (light or dark) is kept in your browser's local storage. We do not use advertising or tracking cookies. Our analytics provider counts page views in aggregate without cookies.
The Service is not directed to anyone under 18, and we do not knowingly collect information from anyone under 18. If we learn that we have, we will delete it and close the account.
The Service is operated from the United States, and your information is processed in the United States and in the regions used by our service providers. By using the Service, you understand your information will be processed in jurisdictions that may have different data protection laws than your own.
We may update this Policy from time to time. Material changes will be communicated through the Service or by email, with the updated effective date shown above. A change that expands how we use your content, adds a provider that receives your conversations, or introduces advertising takes effect for you only after you accept it.
