Your training stays yours.

Guppy is local-first by default. This explains what stays on your device and what leaves only when you use optional services.

Updated: May 28, 2026

Short version

Local-first training

Workout history, progression, routines, programs, timers, and workout media stay on your iPhone by default.

In-app analytics is opt-in

The direct PostHog SDK only starts after you enable the Analytics toggle in Settings, though RevenueCat may still send subscription lifecycle events server-side.

Attribution is permission-based

If you allow Apple's App Tracking Transparency prompt, AppsFlyer may use device identifiers and a signed-in app user ID, when available, for install attribution and campaign measurement across apps and websites.

Community is optional

Convex stores community data only if you browse, import, or publish programs; it also proxies in-app feedback requests.

Feedback is optional

AppFeedbackKit is used only when you submit in-app feedback or answer a feedback prompt.

Accounts stay scoped

An account is required to use Guppy. Clerk is used for sign-in and profile management, while RevenueCat receives an account-linked app user ID plus email or display name when purchases are tied to that account.

What stays on your device

  • Workout history, set logs, timers, progression levels, and workout media are stored locally on your device.
  • Custom routines, local programs, and assessment-driven training preferences are kept in local storage unless you choose to share a program.
  • Daily motivation reminders, analytics consent, and other app preferences are managed locally on your iPhone.

What can leave your device when you use optional services

  • Clerk receives account identifiers plus profile details such as your name, avatar, and verified email address when you sign in or manage your account.
  • RevenueCat receives product identifiers, receipts, entitlement state, an app user ID, and linked subscriber attributes such as email or display name when purchases are tied to an account.
  • If you opt into Analytics, PostHog receives device identifiers, product interaction data, performance data, and a first-party app user identifier directly from the app. RevenueCat may also send subscription lifecycle events and attached subscriber attributes to PostHog through its server-side integration. Session replay is disabled.
  • AppsFlyer receives install, session, and campaign attribution data. If you allow Apple's App Tracking Transparency prompt, AppsFlyer may also use device identifiers and a signed-in app user ID, when available, for attribution across apps and websites.
  • If you use community programs, Convex stores your claimed username and any programs you choose to publish, including titles, descriptions, schedules, routine names, exercise templates, and save counts.
  • If you send in-app feedback, AppFeedbackKit receives your answers, skipped questions, free-text responses you choose to send, app version, device model, OS version, locale, foreground time, launch/session counts, active App Store subscription identifiers when available, and a random app-specific device identifier used to deduplicate responses.
  • If you email support, we receive the message and any attachments you send.

How we use your information

Guppy uses local data to generate workouts, preserve your progression path, and restore unfinished sessions. Clerk is used for account sign-in and profile management, RevenueCat is used for entitlements and referrals, PostHog is used for opt-in product analytics from the app plus subscription lifecycle analytics sent by RevenueCat, AppsFlyer is used for install attribution and campaign measurement, Convex is used for community program features you choose to use and for proxying in-app feedback requests, and AppFeedbackKit is used to collect optional feedback so we can improve the product.

Your choices

  • Use the app with an account, active trial or subscription access, or limited free access after a trial or paid subscription ends.
  • Turn Analytics on or off anytime in Settings.
  • Allow or deny Apple's tracking permission for attribution in iOS Settings.
  • Enable or disable daily motivation reminders from Settings.
  • Dismiss feedback prompts or choose not to submit feedback.
  • Reset local history and progression from Settings, or delete the app to remove local data.
  • Unshare community programs from the app. If you need help with a claimed username or shared content, email support.

Data retention and security

Local data is protected by your device security features. Account, purchase, analytics, attribution, community, and support data is sent over secure connections and retained only as long as needed to operate the service, resolve support issues, or meet legal obligations. Guppy does not show third-party ads in the app. If you allow Apple's App Tracking Transparency prompt, AppsFlyer may use device identifiers and a signed-in app user ID, when available, for attribution across apps and websites.

Kids and eligibility

Guppy is built for people physically capable of performing bodyweight exercise. We do not knowingly collect personal information from children under 13. Parents should supervise any child using a fitness app.
