You retain ownership of all data and content you upload to the Service. By uploading content, you grant us a license to use, store, and process that content solely for the purpose of providing the Service to you.

5.2 Data Accuracy

You are solely responsible for the accuracy, quality, and legality of the data you provide. We are not responsible for any errors in scoring or reporting that result from inaccurate data input.

• You have permission to share that email address with the Service
• The judge has consented to participate in the fair

7. Registration Fees, Cancellations, and Refunds

7.1 How Event Fees Are Determined

Each science fair organizer decides whether its event charges a registration fee, the currency and amount, whether the fee applies per project or per registered student, accepted payment methods, and whether waivers are available. Fair Grading displays the event-owned fee terms during registration. A per-student obligation is calculated from the students on the submitted project roster; a per-project obligation applies once to the project. An authorized correction may update an unpaid obligation when the roster changes.

7.2 Payment

For events that offer online payment through Fair Grading, Ars Practica, LLC is the merchant of record and Stripe processes the payment. The event organizer determines the registration fee and handles event-specific eligibility and refund questions. When online collection is unavailable, applicants must follow the organizer’s displayed instructions. Fair Grading does not collect card or bank account details in its registration forms; payment credentials are entered only on Stripe’s hosted Checkout page. Never enter payment credentials into a free-text registration field.

7.3 Cancellation and Refunds

Canceling or withdrawing a registration does not automatically issue a refund. Refund eligibility, deadlines, and any nonrefundable amounts are determined by the applicable event organizer and its displayed instructions. Contact the fair organizer before canceling or requesting a refund. Any approved refund is returned through an appropriate method and cannot exceed funds previously collected for that registration.

For questions about an event-specific charge or refund, contact the fair organizer identified in the registration materials. For Fair Grading service support, contact Ars Practica, LLC at legal@arspractica.io.
