Privacy Policy

Effective date: April 18, 2026

SweatLog (“we,” “us,” or “our”) values your privacy. This Privacy Policy explains how the SweatLog app and this website handle information.

1. Information We Collect

SweatLog is designed to work without creating an account. We do not collect your name, email address, or other contact information for a SweatLog account.

The app may allow you to enter or save information such as sweat logs, body areas, triggers, treatment notes, outfit logs, photos, and other health-related observations. Unless you use a feature that explicitly sends data elsewhere (for example, sharing or exporting a file you choose), this information is stored on your device and is not uploaded to our servers for storage or backup.

We do not use advertising SDKs, third-party analytics, or social tracking tools in the app for the purpose of profiling you across apps or websites.

If you purchase a subscription or other in-app product, payment is handled by Apple. We do not receive your full payment card information. Subscription entitlements may be processed through RevenueCat so the app can verify your purchase; RevenueCat receives only what is needed to manage subscriptions according to its own privacy policy.

2. How We Use Information

Any information you enter in SweatLog is used only to provide app functionality, such as saving logs, displaying trends and insights, and helping you track symptoms and treatments. We do not sell your personal data to third parties.

3. Data Storage

Your health and symptom data stays on your device. SweatLog does not use iCloud or CloudKit sync for your logs and does not create an online SweatLog account for you. Data remains in local storage on the device unless you export it or share it yourself.

4. Third-Party Services

We rely on the following categories of third parties where applicable:

• Apple App Store — in-app purchases and subscription billing.
• RevenueCat — subscription status and purchase validation.

Each provider has its own privacy policy governing how it handles data related to those services.

5. Your Choices

You can delete your app data by deleting the app from your device (and removing any local backups you control). To remove or manage a subscription, use your Apple ID subscription settings. Export options, if available in the app, let you save a copy of your data where you choose.

6. Children's Privacy

SweatLog is not intended for children under 13. We do not knowingly collect personal information from children under 13.

7. Changes to This Policy

We may update this Privacy Policy from time to time. The updated version will be posted on this page with a revised effective date. For significant changes, we may also provide notice through the app where appropriate.
