Haymaker privacy policy

Last updated: 11 November 2026

Haymaker is a strength training app for iPhone. This policy says what it does with your information. It is short because the app does very little with it.

The short version

Your training stays on your phone. Haymaker has no accounts, no analytics and no tracking. Nothing leaves your phone unless you choose to share a program, connect WHOOP or Withings, or share your training with your own AI.

What stays on your phone

Everything you record lives in a database on your phone and nowhere else:

• Your programs, workouts, sets, weights and notes
• Your exercises, including any you make yourself
• Your body stats: bodyweight, body fat and measurements
• Your settings: units, bars, plates, bands and chains

Haymaker also writes a backup file alongside that database. If you have iCloud Backup turned on, your phone includes that file in its own backup to your iCloud, in the same way it backs up your other apps. That copy is yours, inside your Apple account. Haymaker cannot read it, and neither can we.

You can export everything to a single file at any time, from Settings, and do what you like with it.

What leaves your phone, and only when you ask

**Sharing a program.** If you publish a program, that program is sent to Haymaker's server so other people can open its link. What is sent is the program itself: its name, description, tags, weeks, days, exercises, sets and rest times, along with any custom exercises it uses. Your workouts, your weights, your body stats and your history are never part of it.

Alongside it, the server receives a random identifier that your phone makes up for itself, and the network address your request comes from. These are used to stop one device or one network flooding the service, and for nothing else. The identifier is not tied to you, your Apple account, or anything else about you, and we cannot use it to work out who you are.

You can take a published program down at any time, from the program's own Share screen. Taking it down removes it from the server. Copies other people have already added are theirs and stay with them.

**Reporting a program.** If you report a published program, the server records which program you reported, the reason you gave, and your phone's random identifier, so that the same person reporting twice counts once.

**WHOOP and Withings.** If you connect either service, Haymaker's server holds the access token that service gives it, encrypted. Your health data from those services passes through the server to your phone and is not kept there. Disconnecting deletes the token from the server. Haymaker never has your WHOOP or Withings password: you sign in on their own pages.

**Sharing with your AI.** If you connect Claude, or another AI, on the AI tab, your phone sends Haymaker's server a summary of your training, so an AI you connect, such as Claude, can read it while you chat. The summary holds a year of finished workouts (each day's name, exercise, set and rep counts, volume, time and records), each exercise's best weights and estimated maxes, your bodyweight, body fat, injuries your saved programs with their sets, and the names of the exercises in your list. It never holds your notes, RPEs, measurements or anything else about you. It is sent each time you connect or open Claude from the AI tab, kept for a day, and deleted when that runs out or when you tap Disconnect from Claude. It is served only to whoever has your connector address, which is a long random secret made for your phone. Disconnecting deletes it, and nothing can be read through that address until you reconnect. A program your AI writes for you through the connector waits on the server until you keep or discard it in the app, a week at most. What your AI does with what it reads is covered by that AI's own policy.

What Haymaker does not do

- No accounts. There is nothing to sign up for and no password. - No analytics. Haymaker does not record what you tap, how long you use it, or anything else about how you use it. - No tracking. Nothing about you is shared with advertisers or data brokers, and nothing follows you between apps or websites. - No crash reporting service. If Haymaker fails to start it shows you the problem on your own screen and offers to export your data. Nothing is sent anywhere. - No selling. Your information is not sold, rented or given away.

Children

Haymaker is not aimed at children and asks for no information about age.

Keeping things

Programs you publish stay on the server until you take them down. Tokens for WHOOP or Withings stay until you disconnect. Training you share with your AI stays until it expires or you stop sharing, a week at most. Nothing else of yours is on the server at all.

Your choices

- Export everything: Settings, then Export my data. - Delete a published program: its Share screen, then Take it down. - Disconnect WHOOP or Withings: the Connections screen. - Stop sharing with your AI: the AI tab, then Disconnect from Claude. - Delete everything: remove the app from your phone. That removes the database and the backup file with it. A copy inside your own iCloud backup is removed by Apple when you delete that backup.

Changes

If this policy changes, the date at the top changes with it, and the new version appears here.
