1. Exercise carries risk, and you choose to take it
Stretching and physical activity involve inherent risks. These include muscle strains, ligament and tendon injuries, joint irritation, falls, dizziness, aggravation of an existing condition, and other adverse effects.
Lucy suggests movements. You decide whether to perform them. Every routine, every stretch, and every duration in this app is an offer, not an instruction — you choose whether to begin, whether to continue, and when to stop.
We do not claim that we can never bear responsibility in any circumstance. Some responsibilities cannot be excluded by agreement, and nothing in this document attempts to exclude them. What this section states is narrower and true: the decision to perform any given movement is yours.
2. You are responsible for judging whether the content suits you
Only you, and where appropriate a healthcare professional who knows your history, can assess whether a movement is right for you. You are responsible for evaluating the content in this app against your own:
- health and any current symptoms
- physical condition on the day
- experience with stretching and movement
- past and present injuries
- medical history
- immediate surroundings and circumstances
A routine that suits you on one day may not suit you on another. Nothing in the app tracks this, and nothing in the app can know it.
3. If you have a health condition, ask someone qualified first
Speak to a doctor, physiotherapist or other qualified healthcare professional before starting or continuing to use Lucy if you have, or suspect you may have, anything that could affect your ability to move safely — for example a joint or back problem, recent surgery, a cardiovascular or respiratory condition, a neurological or musculoskeletal condition, or if you are pregnant or recently postpartum.
This list is illustrative, not exhaustive. If you are unsure whether something applies to you, that uncertainty is itself a reason to ask.
4. This is not medical advice
Lucy provides general fitness and stretching information. It does not provide medical advice, diagnosis, treatment, or individualised medical supervision.
Lucy is not a medical device and is not a substitute for a doctor, physiotherapist, or any other qualified healthcare professional. Nothing in the app should be read as a clinical opinion about your body, and no routine in it is designed for, or adapted to, a specific injury or diagnosis.
If you are seeking treatment for a condition, seek treatment. Use this app for what it is: a timer and a set of general stretches.
5. Listen to your body, and change what you are doing
Stop if a movement causes pain, dizziness, light-headedness, breathlessness, numbness, or anything that feels wrong. Discomfort and pain are not the same thing, and the difference is one only you can judge from the inside.
You are expected — encouraged — to adapt. Shorten a stretch, ease off the range of motion, skip a movement, or end a routine early. The app supports all of this: every stretch duration can be changed, and any routine can be left at any point without penalty.
Never force a movement to reach a position shown in an illustration. The figures in this app depict a movement, not a target.
6. Your environment and anything you use
You are responsible for where and how you stretch:
- exercising somewhere with enough space and a stable, non-slip surface
- ensuring nothing nearby could cause injury if you lose balance
- using appropriate technique for the movement
- deciding whether you need assistance or supervision
- ensuring that anything you choose to use — a mat, a wall, a chair, a doorway — is suitable, stable and in safe condition
Lucy does not inspect, and cannot inspect, your surroundings or anything you use. Several routines are written to be performed without equipment or a mat; that does not mean every surface or space is a safe place to perform them.
7. Results are not promised
Lucy makes no promise that use of the app will produce any particular outcome — increased flexibility, reduced stiffness, relief of discomfort, improved posture, or anything else. Bodies differ, and so do results.
