Bio Log Privacy Policy

Last updated June 17, 2026

Bio Log Peptide Journal is designed for personal tracking, organization, and education. The app does not prescribe, diagnose, recommend dose changes, or advise what peptide to use.

Data Stored On Device

Your peptide profiles, vial details, logs, labs, side effects, notes, photos, reminders, and settings are stored locally on your device using Apple platform storage. Bio Log does not require an account.

Data Sent To Services

Bio Log does not send your journal data to an AI service unless you open Bio Log AI, enter or choose a question, and grant permission in the app.

If you allow Bio Log AI data sharing, the app sends your question and a relevant journal summary to the Bio Log backend and OpenAI to generate a response. This may include peptide names, categories, status, vial values, diluent volume, concentration or label notes entered by the user, dose defaults, user-entered draw values, remaining amount, recent dose logs, logged times, sites, side-effect text, notes, recent lab names, values, reference ranges, and side-effect entries.

Bio Log AI does not automatically attach photos, PDFs, exported files, Face ID data, full device data, contacts, location, or advertising identifiers. You can revoke AI data-sharing permission in the app settings.

The Bio Log backend uses the submitted AI request only to call OpenAI and return an answer to the app. Bio Log does not sell your data or use it for advertising.

Purchases

Bio Log AI Monthly subscriptions are processed by Apple using StoreKit. Payment details are handled by Apple. Bio Log checks subscription status on device to unlock optional AI features.

Notifications

Local reminders are scheduled on device. Notification content can be kept discreet inside the app settings.

No Tracking Or Advertising

Bio Log does not use third-party advertising and does not track you across apps or websites.
