Privacy Policy

Effective November 1, 2026

MB Dose Log ("the app") is a personal logging app published by STOIC AFFILIATE LLC ("we", "us").

Your log entries stay on your device

Entries, notes, check-ins, and safety-check answers are stored locally on your device. The app does not require an account. We do not operate servers that receive your log entries, and we cannot see or recover them.

What is processed off your device

• Purchases (RevenueCat). The app uses RevenueCat, Inc. to manage subscriptions and lifetime purchases. When you open the app or make or restore a purchase, RevenueCat processes your purchase status, a random app user ID (not your name or email), the Apple receipt, and technical details such as device type and OS version. This is used only to unlock and restore premium features. See RevenueCat's privacy policy. Your log entries are not sent to RevenueCat.
• Payments (Apple). Payments are processed by Apple. We never receive your card details. See Apple's privacy policy.

What we do not use

The app does not include third-party analytics or advertising SDKs and does not track you across other companies' apps or websites. We do not sell your data.

What the app does not do

MB Dose Log does not diagnose, treat, cure, or prevent any disease or condition, and it does not recommend any amount. It performs arithmetic on values you enter and stores the log you create.

Deleting your data

Deleting the app deletes your log; there is no cloud backup. For purchase records held by RevenueCat, email support@methylenebluetracker.com (mailbox coming soon). Apple keeps its own purchase history for your Apple Account.

Children

The app is not intended for anyone under 18.

Changes

If this policy changes we will update the effective date above.
