These Terms constitute a legally binding agreement between you and Blacklog governing your access to and use of the Blacklog application at blacklog.app. By creating an account or using any part of the Service, you confirm you have read, understood, and agree to be bound by these Terms. You must be at least 16 years of age to use the Service.
Blacklog is a personal trading journal and performance analytics application allowing users to log and analyse trading activity, build a strategy playbook, record psychology reviews, generate performance reports, and calculate position sizing.
⚠ Blacklog is a journaling tool only. Nothing in the Service constitutes financial, investment, or trading advice. All trading decisions are made solely by you. Trading involves significant risk of loss.
You must register with a valid email address. You are responsible for maintaining the confidentiality of your password and all activity under your account. Notify us immediately at support@blacklog.app if you suspect unauthorised access. One account per person — creating multiple accounts to circumvent trial limits or subscription restrictions violates these Terms.
New accounts receive a 7-day free Pro trial beginning at account creation. After 7 days your account reverts to the Free tier automatically. Your data is retained. The trial is offered once per person; using multiple accounts to obtain additional trials is a violation of these Terms.
All payments are processed by Gumroad Inc. Blacklog does not store your payment card details. Subscriptions renew automatically on a recurring basis unless cancelled before renewal. We will provide at least 30 days' notice before any price change. Monthly subscriptions: no refunds after billing commences. Annual subscriptions: pro-rated refund at our discretion if requested within 7 days. Submit requests to support@blacklog.app. Initiating a chargeback without contacting us first is a violation of these Terms.
You must not: use the Service for any illegal purpose; attempt unauthorised access to our systems or other accounts; reverse engineer or decompile the Service; upload malware or harmful code; scrape or use automated tools without written permission; impersonate any person or entity; create multiple accounts to circumvent restrictions; resell or sublicense the Service without written consent; or interfere with Service performance.
Blacklog's design, code, branding, logo, and all content we create are owned by or licensed to us. You own all trade data, notes, and content you create in the Service. You grant us a limited, non-exclusive, royalty-free licence to store and process your content solely to provide the Service to you.
The Service is provided "as is" and "as available" without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant the Service will be error-free or uninterrupted.
To the maximum extent permitted by law, Blacklog shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including trading losses or data loss. Our total liability shall not exceed the amount you paid us in the preceding 12 months or $50 USD, whichever is greater.
You agree to indemnify and hold harmless Blacklog and its affiliates from any claims, liabilities, or expenses arising from your use of the Service, breach of these Terms, or violation of any third-party rights.
You may delete your account by contacting support@blacklog.app. We may suspend or terminate accounts that breach these Terms, with no refund issued for termination for cause. Upon termination, your right to access the Service ceases immediately and data is handled per our Privacy Policy.
Disputes will first be attempted through good-faith negotiation. If unresolved within 30 days, they may be submitted to binding arbitration or competent courts of the applicable jurisdiction.
We will provide 14 days' notice of material changes via email or in-app notice. Continued use after changes constitutes acceptance.

Account data: email address, first name (display name), and password stored in hashed form via Firebase Authentication — we never see your plaintext password.
Trading journal data: trade entries (pair, direction, entry/exit prices, lot size, result, date, notes, images), playbook setups, psychology reviews, and monthly statements. All this data is yours.
Payment data: handled entirely by Gumroad. We receive only your email, Firebase UID, subscription tier/status, and purchase timestamp. We never receive or store your card details.
Technical data: browser type and version, device type, approximate geographic region (country/city — not precise), pages and features accessed, session duration, error logs. Collected via Firebase Analytics and Google Analytics; aggregated and not linked to your identity.
Strictly for: providing, maintaining, and improving the Service; authenticating your account; personalising your dashboard; enforcing subscription tiers; sending transactional emails (no marketing without consent); detecting and preventing fraud; and complying with legal obligations. We do not sell your data. We do not use your trade data for advertising.
Contract performance — to deliver the Service; Legitimate interests — fraud prevention and security; Legal obligation — compliance with applicable laws; Consent — for optional analytics or communications.
All data is stored in Google Firebase (Firestore and Firebase Authentication) on Google Cloud infrastructure, which may include data centres in the United States or other regions. All data in transit is encrypted via TLS/HTTPS. Firebase Authentication handles password hashing. Firestore security rules restrict data access so users can only read/write their own records. Rate limiting and brute-force lockout are implemented on login. In the event of a breach affecting your rights, we will notify you and relevant authorities within 72 hours.
Account and journal data retained while your account is active. On account deletion, personal data is removed within 30 days. Analytics data retained in aggregated form for up to 26 months. Subscription records retained 7 years for financial/tax compliance.
We use: Firebase Authentication tokens (IndexedDB/localStorage) to keep you logged in; Firestore offline cache for offline functionality; Service Worker cache for app assets (no personal data); and localStorage for playbook backups on your device. No third-party advertising cookies. You can clear local storage via browser settings, which will log you out.
Firebase / Google — authentication, database, hosting (privacy policy). Gumroad — payment processing (privacy policy). Google Analytics — aggregated usage analytics (opt out via Google's opt-out add-on). We do not integrate with advertising networks, data brokers, or social media tracking pixels.
Depending on your jurisdiction: right to access, rectification, erasure, restrict processing, data portability, object to processing, withdraw consent, and lodge a complaint with your local data protection authority. To exercise any right email support@blacklog.app — we respond within 30 days.
Blacklog is not directed at children under 16. We do not knowingly collect data from minors. Contact support@blacklog.app if you believe a minor has created an account.
California residents have the right to know what personal information is collected, delete it, and opt out of its sale. Note: we do not sell personal information. Submit a CCPA request to support@blacklog.app with subject line "CCPA Request".
Material changes notified via email or in-app banner at least 14 days before taking effect. Continued use constitutes acceptance.
