If you think you may have a medical emergency, call your doctor, go to the emergency department, or call emergency services immediately.

1. Service Description

BioLogger is a personal health and wellness tracking platform that allows you to:

  • Track body composition, measurements, and other health metrics
  • View trends and correlations in your tracked data
  • Connect with supported health devices and services
  • Export your data for personal use
  • Access insights generated from your data

2. Account Terms

  • Account Creation: You must provide accurate information when creating your account. You are responsible for maintaining the security of your account credentials.
  • Account Requirements: You must be at least 16 years old to use BioLogger. By creating an account, you represent that you meet this requirement.
  • One Account Per Person: Each individual may only maintain one account. Sharing account credentials is not permitted.
  • Account Security: You are responsible for all activity that occurs under your account. Notify us immediately of any unauthorized use.

3. Free Service & Usage

Free Access

BioLogger is currently offered as a free portfolio project. You have full access to all features by signing up with your Google account. No payment or credit card information is required.

AI Token Limits

While most features are unlimited, AI-powered chat features use computational tokens and may have usage limits to prevent abuse. All other features (manual entry, tracking, correlations, exports, etc.) are unlimited and free.

Grandfathered Access

Early users who sign up now will be grandfathered in with free access to all features forever, even if we introduce paid tiers for new users in the future. Your free access will not be revoked, though AI token limits may still apply.

Future Pricing Changes

  • No Charges for Current Users: If we introduce paid plans in the future, current users (those who signed up during the free period) will maintain free access to all existing features.
  • New User Pricing: We reserve the right to introduce paid tiers for new users who sign up after we announce pricing changes. Any such changes will be clearly communicated in advance.
  • No Hidden Fees: We will never charge current users without explicit consent and advance notice of at least 30 days.

Account Termination

You may delete your account at any time through your account settings. We recommend exporting your data before deleting your account, as this action is irreversible and all your data will be permanently deleted.
