Please read these Terms and Conditions, along with our Website Terms and Conditions carefully before participating in a Competition. These Terms and Conditions should also be read in conjunction with our Cookies Declaration and Privacy Policy.

2.1. Entry to Competitions is open to entrants aged 18 years and over resident worldwide (unless you are a resident of a country subject to a UN, US or EU sanction regime, or you are personally subject to any such sanction) ("Eligible Entrants"). Oblivious' directors, management and employees (and their immediate families), its suppliers and service providers that are directly associated with the conduct of the Competitions are ineligible to enter the Competitions.

2.2. To enter a Competition, Eligible Entrants may post, upload, share, store or otherwise provide their code as a submission through the submission form set out on the Website ("User Submission") to a Competition accessible at the following link: https://www.antigranular.com/competitions ("Entry Mechanism"). Your User Submission may be viewed or downloaded by other users. All code submitted in a User Submission is executed on our servers and must use the differential privacy frameworks specified for that Competition.

Eligible Entrants are permitted to collaborate and enter as a team, provided that each Eligible Entrant participating in the team confirms team membership when entering the competition via the Entry Mechanism and does not participate on more than one team for a particular Competition. Teams may also merge with each other, in which case the merged team will take on responsibility for all past entries of each constituent team.

2.5. Competitions will be hosted by Oblivious, and Oblivious is responsible for establishing the Competition rules applicable to each Competition. The Competition rules will set out guidelines in relation to participation in the Competition, the data set(s) to be used by Eligible Entrants, the selection criteria which Oblivious will use to select a winner of the Competition (the "Criteria"), the prize awarded to the winner, and when the prize will be awarded (the "Competition Rules").

If the documentation required by Oblivious is not received by Oblivious (or its nominated agent) or the entrant has not been verified or validated to Oblivious' satisfaction within the time requested, that entrant’s entry will be invalid. Proof of identification, residency and entry considered suitable for verification is at the sole discretion of Oblivious. The prize(s) will only be awarded following any validation and verification of the entrant that Oblivious requires in its sole discretion. In the event that an entrant cannot provide suitable proof, the relevant prize will be forfeited and no substitute will be offered as the entrant will be disqualified.

2.9. Eligible Entrants may not use any automated means to enter a Competition, or enter into any Competition using bulk entries (unless expressly provided for in the Competition Rules).

3.1. Oblivious will provide you with information about the prizes via the Website.

3.3. The winner(s) will be notified via email.

3.4. The prize must be taken as offered and cannot be varied by the winner(s). Prizes are not transferable or exchangeable and cannot be taken as cash.

As a condition of accepting the prize, the winner (and his/her team member(s), if applicable) may be required to sign any legal documentation as and in the form required by Oblivious and/or prize suppliers in their absolute discretion, including but not limited to a legal release and indemnity form, indemnifying Oblivious from any legal claims related to the receipt or use of the prize.

3.7. Oblivious encourages the responsible use of prize(s), in accordance with applicable legislation.

3.8. If for any reason a prize, or any part of a prize becomes unavailable for any reason beyond Oblivious' reasonable control, Oblivious reserves the right to substitute the prize (or part thereof) for an alternative prize to the same or greater value of the original prize value, subject to applicable law.

3.9. Where applicable, Oblivious reserves the right to refuse to allow the prize winner (or any of their team members, if applicable) to take part in any or all aspects of the prize if Oblivious determines, in its absolute discretion, that the prize winner (or any of their team members, if applicable) are not in the mental or physical condition necessary to be able to safely participate in or use the prize.
