1.1 General Terms and Conditions: these conditions.
1.2 HBJJ: the sole proprietorship Haven BJJ, registered in Rotterdam and located at 3013 AL Rotterdam at Weena 1099, registered in the trade register of the Chamber of Commerce under number 70098840.
1.3 Participant: a person who has a subscription with HBJJ or attends classes from HBJJ.

1.6 Written: by letter or by email.
1.7 Parties: HBJJ and Participant together.
2.1 These General Terms and Conditions apply to the formation and execution of the Agreement between HBJJ and Participant, the entry to the training school, and participation in classes from HBJJ.
2.2 By signing the registration form, entering the training school and/or participating in classes of HBJJ, the Participant agrees to the application of these General Terms and Conditions.
2.3 If HBJJ does not always require strict compliance with these General Terms and Conditions, this does not mean that these General Terms and Conditions would not apply to the Agreement, entry into the training school, or participation in classes, nor that HBJJ would lose the right to demand strict compliance with these General Terms and Conditions in future, similar cases.
2.4 Deviations from and/or additions to these General Terms and Conditions are only valid if they have been expressly agreed upon in writing between the Parties.
2.5 Additional and/or differing conditions of the Participant do not bind HBJJ, unless HBJJ has expressly accepted those conditions in writing. Acceptance of the Participant's conditions cannot be inferred from the circumstance that HBJJ does not contest a notification from the Participant that he does not accept these General Terms and Conditions and declares his own conditions applicable. In the event of a contradiction between these General Terms and Conditions and the conditions of the Participant, these General Terms and Conditions prevail unless HBJJ has expressly and in writing agreed otherwise with the Participant.
2.6 When these General Terms and Conditions are amended during the term, the amended version applies one month after the date on which the amendment has been communicated in writing to the Participant, unless the Participant objects to the applicability of the amended General Terms and Conditions within fourteen days of receiving the notification that the General Terms and Conditions are being amended.
2.7 If one or more provisions in these General Terms and Conditions are wholly or partially null and void or are annulled, the remaining provisions in these General Terms and Conditions remain fully applicable. The Parties will then consult to agree on new provisions to replace the null and void or annulled provisions, taking into account the purpose and intent of the original provisions as much as possible.
3.1 The Agreement between the Parties is established by the registration of the Participant via the online system (Grib) with the acceptance of the General Terms and Conditions and the acceptance of the registration by HBJJ.
3.2 The Agreement can be dissolved by the Participant without stating reasons up to a maximum of fourteen days after the day on which the Agreement was concluded. If the Participant participates in classes of HBJJ during this fourteen-day period and subsequently invokes the right of withdrawal, he owes a proportional compensation for the classes he has attended.
4.1 The Participant can enter into an Agreement with HBJJ for four weeks or for one year. The Agreement entitles the Participant to attend an unlimited number of classes per week during the subscription period. The Agreement is personal and non-transferable.
4.2 For children and students, an Agreement can be entered into at a reduced rate. To qualify for this, students must provide proof of enrollment from the educational institution each year. The regular terms and conditions will apply to the Agreement once the age of eighteen is reached or if there is no longer enrollment at an educational institution.
4.3 Before entering into an Agreement for four weeks or a year, the Participant can enter into a trial Agreement at a reduced rate. The same terms and conditions apply to that Agreement as to an Agreement for four weeks or for a year.
4.4 The Agreement takes effect on the date of its establishment. Unless terminated, the Agreement will continue after the specified period for an indefinite period.
4.5 If the Agreement has been extended for an indefinite period after the specified period, the Participant can terminate the Agreement at any time with a notice period of at least four weeks. In that case, the Agreement will end after the current four-week payment period following the expiration of the notice period.
4.6 By entering into the Agreement, the Participant declares to be familiar with the General Terms and the house rules of HBJJ. The Participant accepts the General Terms and the house rules of HBJJ. HBJJ reserves the right to change the house rules.
5.1 The compensation owed by the Participant every four weeks amounts to the amount established by HBJJ at the time of the establishment of the Agreement. The amount of the compensation is displayed on the HBJJ website.
5.2 HBJJ is entitled to increase the compensation a maximum of once per calendar year. An increase in the compensation will be communicated to the Participant in writing as soon as the increase is known, but no later than four weeks before the increase takes effect. In the event of an increase in the compensation, the Participant has the right to terminate the Agreement within four weeks after the announcement of the increase.
5.3 The first payment of the compensation is made by bank transfer via iDeal or credit card. Subsequently, the compensation is deducted every four weeks via credit card or SEPA Direct Debit.
5.4 If the Participant is negligent in fulfilling the due payment, HBJJ will be entitled to charge the statutory collection costs in accordance with the Collection Costs Act and the statutory interest. These costs and interest will be added to the outstanding amount and will be paid by the Participant, in addition to the originally owed fee.
6.1 HBJJ will make an effort to offer sufficient and varied classes in Brazilian jiu jitsu throughout the year from Monday to Friday according to the schedule to be drawn up by HBJJ.
6.2 HBJJ determines the opening hours, its schedule, its lesson location, and lessons.

7.3 Participant must register online in advance via the Haven BJJ App (Grib) for the class they wish to attend. Without registration, the Participant has no right to attend the class. The Participant agrees that registration for a class constitutes an obligation to participate in that class.
7.4 If the Participant refrains from attending the class after registering without notifying by phone or in writing at least two hours before the start of the class, this is considered a "no show." In that case, the Participant forfeits a fine of € 10.00 per no show without further warning or announcement. If the Participant has refrained from attending classes for which they have registered more than three times, HBJJ is also entitled to limit the Participant's classes to a maximum of six classes per week without the Participant having the right to partial reduction or refund of the fee or compensation for damages.
7.5 The Participant declares by entering into the Agreement that they are in good physical and mental health and that there are no medical reasons or other obstacles that make participation in HBJJ classes irresponsible.

The maximum duration of suspension is 12 weeks per calendar year, unless HBJJ agrees otherwise in writing. HBJJ reserves the right to request further information in case of doubt.
8.1 If the Participant fails to comply with any of the obligations related to the Agreement or the General Terms and Conditions, does not follow the instructions of instructors/trainers, and/or does not adhere to the rules of play or house rules of HBJJ, HBJJ is authorized to deny the Participant access to the training school or participation in classes (temporarily) and/or to terminate the Agreement with the Participant immediately without further notice of default being required unless the breach, due to its minor nature, does not justify the relevant measure. In case of suspension or interim termination of the Agreement, the Participant has no right to a refund or compensation for damages.
