™Questions about this policy? privacy@mymarketbook.com
Information you provide
We receive information you choose to submit, including your name, email address, messages, subscription preferences and purchase-support details. Use general forms for ordinary support, not confidential financial advice. Do not send Social Security numbers, full payment-card details, brokerage credentials, account passwords or sensitive account statements.
Purchases and payment processing
Stripe processes payment under its own terms and privacy policy. We may receive order details such as purchaser name, email, product, amount, payment status, transaction date and receipt identifiers for delivery, accounting and support. Our website does not collect payment-card numbers through its contact forms. Review the payment provider’s policy before entering payment information.
Technical information and security
Hosting and security providers may process IP address, browser and device information, timestamps, requested pages and diagnostic or abuse-prevention records. Such information helps operate, secure and troubleshoot the service. Essential processing is separate from optional website analytics.
Calculators, practice and browser storage
Educational calculations and saved learning features use information entered in your browser. Where a feature saves progress, answers, notes or a shopping bag locally, those records remain in that browser unless you choose an export, sharing or submission feature. Browser records are not a secure financial vault, a cloud backup or an account that synchronizes across devices. Some previously saved learning records may remain after a feature is retired. You can clear site data in your browser; this may also remove your bag, progress and privacy preference. Shared-device users should consider who can access their browser. Tool interaction analytics, when allowed, use limited event categories rather than private notes, credentials or free-text financial details.
Privacy choices, cookies and optional analytics
Local storage remembers privacy preferences and supports requested features. Optional Google Analytics 4 is enabled only after you choose "Allow analytics." "Essential only" leaves optional analytics off. Supported Global Privacy Control and Do Not Track signals keep optional analytics disabled. Change your selection through "Privacy choices" in the footer. With consent, analytics may measure pages, general traffic sources, downloads, tool interactions and checkout starts. We do not enable analytics for personalized advertising. Blocking or clearing browser storage can affect saved preferences and features; you can continue reading without optional analytics.
How information is used
We use information to operate and secure the site, deliver requested communications and purchases, respond to support and correction requests, keep business records, investigate billing or abuse, improve the service and comply with legal obligations. Where required by applicable law, we use an appropriate legal basis, such as performing a purchase contract, consent for optional processing, legal obligations or legitimate operational and security interests.
Email communications
Requested service messages may include confirmations, access help and billing or correction responses. Marketing and newsletter messages require a separate subscription where applicable; buying a book or sending a support request is not blanket permission for unrelated marketing. Use the unsubscribe link in marketing email or contact privacy@mymarketbook.com. Necessary transaction or security messages may continue after marketing is stopped.
Providers and disclosures
Providers supporting hosting and security, email delivery, analytics, payment processing and storage may receive information needed to perform those services. Our service stack includes Cloudflare for hosting/security, Resend for website email delivery, Google Analytics for consent-based measurement and Stripe for payment processing. We may also disclose information to professional advisers, where legally required, to address fraud or protect rights, or in a lawful business transfer with appropriate safeguards. We do not sell personal information for money or use website analytics for targeted advertising. If our practices change, we will provide required notices and choices before applying a materially different use.
Retention
We keep information only as reasonably needed for its purpose, support, accounting, security and legal obligations. Website email delivery-queue records are removed after seven days when processing runs; daily request-limit records expire after two days. Delivered inbox messages, transaction records and email-provider records have separate operational or legal retention requirements. Browser-local records remain until removed by the feature, browser or user. Deletion requests can be subject to lawful retention exceptions.
Safeguards and incidents
We use reasonable safeguards appropriate to the information and service. No transmission or storage system is completely secure. If a security incident triggers legal notification or other obligations, we will address those obligations under applicable law. A security limitation does not waive our duties to safeguard personal information.
Requests and applicable privacy rights
Depending on your location and which laws apply, you may have rights to access, correct, delete or receive personal information, restrict or object to processing, withdraw consent, opt out of particular disclosures, or appeal a denied request. Send requests to privacy@mymarketbook.com or use Contact → Privacy request. We may verify identity using proportionate information and may retain records needed to comply with law. Do not send identity documents unless we arrange a suitable method. You may also contact the relevant privacy regulator. We do not penalize the exercise of rights protected by applicable law.
Children and international visitors
The site is general-audience education and is not directed to children under 13. We do not knowingly collect their personal information; contact privacy@mymarketbook.com if you believe this has occurred so we can investigate and take appropriate action. Our business operates in the United States. Providers may process information in the United States or other jurisdictions, subject to applicable data-protection requirements. Visiting the site is not by itself a waiver of privacy rights.
External services and policy updates
Linked websites and external checkout have separate privacy practices; review their policies. We post material changes here with a revised effective date and provide additional notice or obtain consent when required. Updating this text alone does not authorize a new use that requires consent.
