In the unlikely event that Coach Tim needs to cancel a session, you will be notified as early as possible and the session will be fully returned to your package or rescheduled at a time of your choosing — no session is lost.

Under EU consumer law, you have the right to cancel a purchase within 14 days of the date of purchase and receive a full refund, provided no sessions have been used. If you have used one or more sessions within the 14-day period, a partial refund will be issued for unused sessions minus a €35 administration fee.
After the 14-day cooling-off period, no refunds are issued on session packages. In exceptional circumstances (e.g. serious illness or injury), a credit toward future services may be offered at Coach Tim's discretion.
To request a refund within the cooling-off period, contact timothacker@gmail.com stating your name, purchase date, and reason. Refunds are processed within 5–10 business days to the original payment method.
By booking a session with Barracuda BJJ, you confirm that you are medically fit to participate in physical exercise and that you are not aware of any condition that would make exercise inadvisable without medical supervision.
All new clients are required to complete a Physical Activity Readiness Questionnaire (PAR-Q) prior to their first session. This is provided during the intake/introduction session or via the Calendly booking form. Providing accurate and complete health information is your responsibility.
You must inform Coach Tim of any injuries, medical conditions, or physical limitations before commencing training. This includes but is not limited to: cardiovascular conditions, musculoskeletal injuries, recent surgery, chronic pain, or pregnancy. Failure to disclose relevant health information releases Barracuda BJJ from liability for any resulting harm.
Coaching and programming provided by Barracuda BJJ is for fitness and performance purposes only and does not constitute medical advice, diagnosis, or treatment. While Coach Tim holds an MSc in physiotherapy (candidate), the coaching relationship is not a clinical one. If you have a medical concern, consult a qualified healthcare professional.
Participation in personal training involves inherent physical risk. Barracuda BJJ takes all reasonable precautions to ensure your safety, however Barracuda BJJ cannot be held liable for injury, loss, or damage arising from participation in sessions, provided reasonable care has been taken by the coach. You participate at your own risk.
If your health status changes at any point during your coaching programme — including new injuries, illness, or medical diagnoses — please inform Coach Tim before your next session so your programme can be adjusted accordingly.
All coaching relationships are strictly professional. Coach Tim reserves the right to terminate a coaching relationship at any time if a client behaves in a disrespectful, threatening, or inappropriate manner. In such cases, a refund for unused sessions will be issued.
Barracuda BJJ reserves the right to refuse or discontinue service to any client whose behaviour is deemed inappropriate, or whose health status presents a risk that falls outside the scope of personal training coaching.
