Who we are

LiftSets is published by Christopher Newell, 9 Spur Trading Estate, Wymondham, NR18 0NL, United Kingdom. Contact: support@liftsetsapp.com.

The short version

• Your training data is stored on your iPhone.
• There are no accounts. We do not know who you are.
• We do not sell data. We do not show adverts in the app.
• Data leaves your phone for our systems in three cases only: when you ask for a written review, after you have agreed to it; when you enter a personal trainer's code; and when you choose to send us a suggestion or a bug report.

What the app stores on your phone

• Your plan and the workouts you log: exercises, weights, reps, times, notes.
• Runs you log: distance and time.
• Settings such as units and rest times.
• If you use them: body weight entries and injury notes.

This stays on your device. It is included in your iPhone's own backup if you have that switched on.

Apple Health

If you allow it, the app reads your body weight from Apple Health. It never writes to Apple Health. Health readings stay on your phone. They are not sent to us, not stored in iCloud by the app, and not used for advertising.

The written review (Pro)

If you subscribe and ask for a written review, the app sends the facts of that workout to our server: exercises, weights, reps, rest times, your note for the session, your training phase, and any injury pattern the app has spotted. Our server passes them to Anthropic, the company that provides the AI model that writes the review. Nothing that identifies you is sent: no name, no email, no Apple ID.

You are asked to agree before the first review is written. You can withdraw that at any time in Settings. We do not keep the workout facts after the review is returned. Our server keeps a count of how many reviews have been written, and nothing about what was in them. Anthropic's handling of data is described in its own privacy policy.

The review is written by AI. It is training guidance, not medical advice.

Purchases

Subscriptions are sold by Apple. We receive confirmation that a subscription is active. We do not receive your name or payment details.

Trainer codes

If you enter a personal trainer's code, the app sends that code and Apple's confirmation of your subscription to our server, so the trainer can be paid commission. We record the code, a subscription reference number from Apple, the plan, and what was paid and when. We do not record your name or contact details, and the trainer is not told who you are. Your trainer sees each person who used their code as a made-up reference, with the plan, the month it started, whether it is still running, and what was paid. If you are the only person who has used their code, they may be able to work out that the entry is you.

Apple also tells our server when a subscription that used a trainer's code renews, is cancelled or is refunded. We keep the link between a subscription and a trainer for two years from the first purchase, and payment records for seven years because tax law requires it.

If you are a trainer in the scheme, we hold your name, email address, code and bank details to run the scheme and pay you, and keep payment records for as long as tax law requires.

Suggestions, bug reports and emails

Settings has two buttons, Suggest an improvement and Report a bug. When you send one, we receive what you typed, the app version, the iOS version, the model of phone (for example "iPhone18,1") and whether you are on Free or Pro. The screen shows you this before you send. Nothing about your workouts is sent, and nothing that says who you are, unless you choose to add an email address so we can reply.

We use these to fix problems and decide what to build. They are kept for up to 13 months and then deleted. An email address you gave is deleted with the message, or sooner once we have dealt with it. To stop flooding, our server counts messages per internet connection for one day using a scrambled value. It does not store your internet address.

If you email us instead, we receive your email address and whatever you write. We use it to reply and to fix the problem.

Tracking and adverts

The app does not track you across other companies' apps or websites. This website uses no cookies and no trackers.

Children

LiftSets is for adults aged 18 and over.

Your rights

Under UK data protection law you can ask what personal data we hold about you, ask us to correct or delete it, and complain to the Information Commissioner's Office (ico.org.uk). Because the app has no accounts and keeps your data on your phone, in most cases we hold nothing. Deleting the app deletes its data from your phone.

Consumer health data (Washington State, Nevada and similar US laws)

Some of what the app handles counts as consumer health data: training logs, body weight and injury notes.

• What we collect: only the workout facts described under "The written review", and only when you ask for a review.
• Why: to write the review you asked for.
• Who receives it: Anthropic, to generate the review.
• We do not sell consumer health data.
• You can withdraw consent in Settings and ask us to delete anything we hold by emailing support@liftsetsapp.com.

Changes

If this policy changes in a way that matters, the app will tell you before the change takes effect.
