OrderedStrength Privacy Policy

Last updated: 17 August 2026. This policy covers the OrderedStrength iPhone app. It does not cover any other service.

The short version

Your training lives on your phone. We have no account system, so we do not know who you are. Three things can leave your device, two of them only if you switch them on, and none of them is your training log.

What stays on your device

All of this is stored on your iPhone and is never sent to us:

• Your name, age, bodyweight, height and sex, if you enter them.
• Every set you log: exercise, weight, reps, and the reps you had left in reserve.
• Any injury you record, and how you said it felt.
• Everything the coach learns about you: your strength estimates, fatigue model, calibration and history.

If you delete the app, this goes with it. That is why the app offers a backup file you keep yourself.

Apple Health

Only if you grant permission, the app reads: heart rate variability, resting heart rate, heart rate, sleep analysis, and active energy. It writes completed workouts back to Health so they appear alongside your other activity.

Health data is used on your device to inform recovery and readiness. It is never transmitted to us or to anyone else. You can revoke access at any time in Apple Health, and the app keeps working without it.

The three things that can leave your device

1. Jerry's voice · on when the spoken coaching voice is on

To speak in a natural voice rather than the built-in system voice, the text of the sentence Jerry is about to say is sent to our server, which forwards it to Microsoft Azure to turn into audio. Jerry's lines are a bounded set of templates, and each distinct line is fetched once and then stored on your phone and replayed from there forever.

Be aware: a spoken line can contain numbers from your session, such as a weight or a rep count, because that is what the sentence says. It never contains your name, and no other part of your training log is sent. Turning the voice off stops this entirely.

2. Ask Jerry · OFF unless you turn it on

If you enable Cloud Answers, then when you ask Jerry a question in chat, your typed question and the relevant training context needed to answer it are sent to our server, which forwards them to Anthropic to compose the reply. This is off by default. With it off, Jerry answers from the on-device engine and nothing is sent.

3. A daily usage summary · on by default, and you can turn it off

Once a day the app can send a short summary so we can tell whether the app is actually helping people train. It is tied to a random identifier created on your device, never to your name, and it contains day-level values only:

• which days you opened the app, and which days you trained;
• how far you got in setup, and how long it took to log a first set;
• how many times the app crashed;
• which language you use.

It does not include your sets, your weights, your body data, or anything from Apple Health. You can switch it off in Profile → Data & Privacy, and switching it off stops it completely.

What we never do

• No advertising, and no advertising networks.
• No third-party analytics or tracking SDKs. There are none in the app.
• No tracking you across other apps or websites, and no Advertising Identifier.
• No selling or sharing your information with data brokers.
• No account, so no email list, and no profile of you held on our side.

Your controls

• Back up everything and restore a backup, in Profile → Data & Privacy. The file is yours.
• Delete all training data, in the same place. This is immediate and cannot be undone.
• Turn off usage sharing, in the same place.
• Turn off Cloud Answers, in Settings.
• Revoke Apple Health access, in the Apple Health app.
• Delete the app, which removes everything stored on the device.

Service providers

Where data does leave the device it passes through our own server and then to: Microsoft Azure (speech synthesis) and Anthropic (chat answers, only with Cloud Answers on). They process it to return the result and we do not authorise them to use it for their own purposes.

Children

OrderedStrength is a strength-training tool intended for adults. It is not directed at children under 13, and we do not knowingly collect information from them.

Changes

If what the app does with data changes, this page changes with it and the date above is updated. The page is written from the app's own source code so that it stays true rather than generic.
