Privacy Policy & Support — Heft

Effective date: 7 September 2026

Heft is a workout tracker built by Luke Kavenagh. This page covers both privacy and support.

The short version

Heft does not collect your data. There are no accounts, no ads, no analytics and no tracking. Your workouts are stored on your phone and are never sent to me or to anyone else.

What Heft stores, and where

What	Where it lives	Leaves your device?
Workouts, exercises, sets, weights, reps, personal records	A database file on your phone	No
Preferences (units, rest-timer settings, last backup date)	Your device's secure storage — iOS Keychain, Android Keystore	No
Backup files you export yourself	Wherever you choose to save them	Only if you send them somewhere

That is the complete list. There is no server behind Heft, and no account for you to create, so there is nowhere for your data to be sent.

What Heft does not do

No user accounts, sign-in, or email collection
No advertising, ad networks, or advertising identifiers (no IDFA)
No analytics, telemetry, crash reporting, or usage tracking
No third-party tracking SDKs of any kind
No access to your location, camera, microphone, contacts, photos, or health data
No selling, renting, or sharing of personal information — there is none to sell

Heft makes no network requests in normal use. The only exception is Apple's or Google's own purchase system if you choose to leave a tip.
