Effective date: November 11, 2026 · Publisher: FOP Oleksandr Seleznov (ФОП Селезньов Олександр Андрійович) · Contact: healthledger.support@gmail.com
These Terms of Use (“Terms”) govern your access to and use of the Health Ledger Android application and web application (https://app.health-ledger.app). By signing in to or using Health Ledger, you agree to these Terms and acknowledge our Privacy Policy.
1. Service Provider & Scope
Health Ledger is provided by:
- Legal Entity / Publisher: Individual Entrepreneur FOP Oleksandr Seleznov / ФОП Селезньов Олександр Андрійович (OLEKSANDR SELEZNOV)
- Registered Business Address: Ukraine, 08301, m. Boryspil, vul. Bankivska, bud. 32, kv. 47 (Україна, 08301, м. Бориспіль, вул. Банківська, буд. 32, кв. 47)
- Support & Legal Contact: healthledger.support@gmail.com
You must be at least 18 years old (or the age of legal majority in your jurisdiction) to use Health Ledger.
2. No Medical Advice, Diagnosis, or Emergency Care
Health Ledger is a personal health record-keeping and wellness journaling tool. It is not a healthcare provider, clinical decision support system, or regulated medical device.
- Informational purposes only: All content, charts, nutrition estimates, medication reminders, document summaries, and AI responses in Health Ledger are provided strictly for personal tracking and general educational purposes. Nothing in Health Ledger constitutes medical advice, clinical diagnosis, prognosis, or treatment recommendations.
- Consult a qualified professional: Always seek the advice of a physician or other qualified healthcare provider with any questions regarding a medical condition, lab result, diet, or before starting, changing, or stopping any medication or treatment plan. Never disregard professional medical advice or delay seeking it because of information displayed in Health Ledger.
- Not for emergencies: Do not use Health Ledger or its AI assistant for medical emergencies. If you believe you or someone else may be experiencing a medical emergency, call your local emergency number or a physician immediately.
3. Artificial Intelligence (Gemini) Features
Health Ledger integrates Google Gemini artificial intelligence models to assist with conversational questions, food journal logging, voice transcription, and summarizing user-provided documents:
- Potential for errors: AI-generated outputs are produced probabilistically and may be incomplete, inaccurate, miscalculated, or outdated. You are solely responsible for verifying any AI-generated summary, nutrition estimate, or response against your original medical records and with a qualified healthcare professional.
- In-app disclaimer agreement: Use of Gemini chat requires reviewing and accepting the in-app AI & medical disclaimer. When the disclaimer is updated, you may be prompted to review and accept the updated notice before continuing to use AI chat features.
4. Google Sign-In, Google Drive Storage & Health Connect
- Your Google account: Health Ledger uses Google Sign-In for authentication and stores your food journal, medical records, medication courses, and AI chat history in your personal Google Drive hidden application data folder (
appDataFolder). - Data availability & backups: Because your health ledger files reside in your own Google Drive and local device caches, availability depends on your Google account status, Google Drive storage quota, and device storage. You are responsible for maintaining access to your Google account and keeping copies of original medical documents.
- Health Connect & Google Health: Connecting Android Health Connect or Google Health is optional and governed by the permissions you grant on your device or Google account, as described in our Privacy Policy.
5. Subscriptions, AI Quotas & Billing
- Service tiers & AI allowances: Health Ledger is free to install, sign in to, and use for managing your data. Gemini AI access may include a one-time Starter allowance and optional paid subscriptions (
Basic,PlusandExtra) with recurring AI allowances. The Starter allowance does not renew; any expiry is shown in the app. AI usage, including pending requests, counts against the applicable allowance. Account deletion or signing in again does not reset an allowance. - Google Play billing: Paid subscriptions on Android are billed and processed through Google Play. Subscriptions automatically renew at the end of each billing period unless canceled before the renewal date in Google Play (Google Play Store → Payments & subscriptions → Subscriptions).
- Cancellations & refunds: You may cancel a subscription at any time in Google Play; after cancellation, your paid tier remains active until the end of the current paid period. Refunds are handled in accordance with Google Play refund policies and applicable mandatory consumer laws.
- Deleting account data vs. active subscriptions: Deleting your Health Ledger account data inside the app removes your application data but does not automatically cancel an active recurring Google Play subscription. You must cancel active subscriptions in Google Play.
6. Acceptable Use & Service Integrity
You agree not to misuse Health Ledger or its backend services. Specifically, you must not:
- Attempt to bypass, spoof, or interfere with authentication, Google Play Integrity checks, subscription verification, or AI quota and rate-limit controls;
- Use automated scripts, scrapers, or unauthorized clients to access the Health Ledger API or consume AI allowances;
- Upload malware or content that infringes third-party rights or violates applicable law.
We reserve the right to restrict, rate-limit, or suspend access to backend API and AI features if we detect abuse, security threats, or violations of these Terms.
7. Account Deletion & Termination
You may stop using Health Ledger and delete your account and associated data at any time through Settings → Privacy & your data → Delete account & data in the app or by following the instructions at https://health-ledger.app/delete-account.
8. Disclaimer of Warranties & Limitation of Liability
- Provided “AS IS”: To the maximum extent permitted by applicable law, Health Ledger is provided on an “AS IS” and “AS AVAILABLE” basis without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, accuracy, or uninterrupted availability.
- Limitation of liability: To the maximum extent permitted by applicable law, FOP Oleksandr Seleznov shall not be liable for any indirect, incidental, consequential, special, or exemplary damages, or for any loss of data, health outcomes, or reliance on AI-generated outputs or reminder notifications. Where liability cannot be excluded by law, total aggregate liability for any claim arising out of or relating to Health Ledger shall not exceed the amount you paid for Health Ledger subscriptions in the twelve (12) months preceding the claim.
9. Governing Law, Consumer Rights & Updates
- Governing law: These Terms are governed by the laws of Ukraine, without regard to conflict-of-law principles. If you are a consumer residing in the European Economic Area, the United Kingdom, or the United States, nothing in these Terms deprives you of mandatory consumer protection rights granted by the laws of your country or state of residence.
- Updates to these Terms: We may update these Terms as Health Ledger evolves. When we make material changes, we will update the effective date at the top of this page. Continued use of Health Ledger after updated Terms take effect constitutes acceptance of the revised Terms.
