Privacy Policy

Last updated: April 2026

Summary

Anvil Workout does not collect, store, or transmit any personal data to external servers. All your workout data stays on your device and in your iCloud account (via device backup).

Data storage

All data — workout programs, session history, and preferences — is stored locally on your device using Apple's SwiftData framework. Nothing is sent to any server.

Apple Health

If you grant permission, Anvil Workout writes workout sessions to Apple Health and reads calories burned and heart rate data. This data is handled entirely by Apple's HealthKit framework and stays within Apple's Health ecosystem. Anvil Workout does not access, export, or transmit Health data beyond what HealthKit provides.

Crash reporting

Anvil Workout uses Sentry for anonymous crash reporting and performance monitoring. This helps us find and fix bugs. Sentry may collect:

No personal data, workout data, or Health data is included in crash reports.

Analytics

The Anvil Workout iOS app does not use analytics or tracking and contains no ads. Your workout data never leaves your device.

This marketing website (anvilworkout.iamjarl.com) uses Umami, a privacy-respecting, cookieless analytics service, to count anonymous page visits. Umami does not use cookies, does not track visitors across sites, and collects no personal data. The collected data is limited to aggregate page-view counts, referrer, and general device/browser type.

Third-party services

The external services used are Sentry (anonymous crash reporting from the app) and Umami (anonymous visit counts on the marketing website). No data is shared with advertisers, data brokers, or any other third party.

Children's privacy

Anvil Workout does not knowingly collect data from children under 13.
