Lastset Terms of Use
Last updated: 5 September 2026
These terms cover your use of Lastset, an iPhone app made by Utileau. By installing or using it, you agree to them.
1. What Lastset is
Lastset is a strength training log. It records the workouts you enter, suggests weights based on what you logged before, and can generate a training programme and calorie estimates from answers you give it.
It is a tool for keeping records and doing arithmetic. It is not a coach, a trainer, or a medical professional.
2. Not medical or professional advice
This is the important one.
Lastset is not a medical device and does not provide medical, dietary or professional fitness advice. Everything it shows you — suggested weights, estimated one-rep maxes, training programmes, calorie and macro targets — is produced by published formulas and simple rules applied to numbers you typed in. None of it is personalised to your health, your injuries, your medication or your circumstances.
- Resistance training carries risk of injury. You are responsible for your own technique, your own loading decisions, and for knowing when to stop.
- Suggested weights are suggestions. The app cannot see your form, your sleep, your stress or how you feel today. Ignore it whenever your judgement says otherwise.
- Calorie and macro targets are estimates. They come from the Mifflin-St Jeor equation and standard activity multipliers, clamped to conservative minimums. They are not a diet plan and they are not suitable for everyone.
Talk to a doctor before starting or significantly changing a training or eating programme, especially if you are pregnant, under 18, recovering from injury or illness, or managing any health condition. If something hurts, stop and seek proper advice.
3. Your data
Lastset has no accounts and no servers. Everything you log stays on your device and, if you use iCloud, in your own iCloud account. See the Privacy Policy.
Keeping your data is your responsibility. We cannot recover anything for you, because we never have it. Use the export function regularly if your history matters to you — it is in Profile → Settings.
We are not liable for data you lose through device failure, deleting the app, turning off iCloud, running out of iCloud storage, or using Delete all data.
4. Lastset Pro
Some features require a paid subscription or a one-off lifetime purchase.
Purchases are made through Apple, not through us. Payment is charged to your Apple Account at confirmation.
- Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours of the end of the period.
- Manage or cancel in iOS Settings → your name → Subscriptions. Deleting the app does not cancel a subscription.
- A free trial, where offered, converts to a paid subscription unless cancelled at least 24 hours before it ends. Any unused portion of a trial is forfeited if you buy a subscription during it.
- Lifetime is a one-off purchase tied to your Apple Account. It does not renew.
- Restore Purchases is in the paywall, top right. Use it on a new device.
We cannot issue refunds. Apple processes every payment and handles every refund. Request one at reportaproblem.apple.com. We say this plainly rather than have you ask us for something we are unable to do.
Prices and what each tier includes may change. Changes never affect a subscription period you have already paid for, and a lifetime purchase stays valid for the features it covered.
5. Acceptable use
Do not:
- reverse engineer, decompile or attempt to extract the app's bundled content
- redistribute the exercise library or the plan library as your own dataset
- use the app in a way that breaks the law
The exercise descriptions, the prebuilt programmes, the app's design and its code belong to Utileau or its licensors. Your own training data belongs entirely to you.
6. Availability
Lastset is provided as-is. We do not promise it will be free of bugs, that it will work on every device or iOS version, or that it will remain available. We may change or discontinue features.
Because the app has no server component, it will keep working on your device whatever happens to us — and your export files will keep opening in anything that reads JSON or CSV.
7. Liability
To the fullest extent permitted by law, Utileau is not liable for injury, loss or damage arising from your use of Lastset, including from following a suggested weight, a generated programme or a calorie estimate, or from lost training data.
Nothing in these terms limits liability that cannot be limited by law, including for death or personal injury caused by negligence, or for fraud. If you are a consumer, you keep all statutory rights available to you.
8. Changes
We may update these terms. The date at the top shows when they last changed. Continuing to use the app after a change means you accept the updated terms.
