Refund Policy

Effective Date: March 18, 2026 · Last Updated: July 27, 2026

This Refund Policy applies to all purchases made through lumitone.io, operated by Deruvish Labs LLC ("Lumitone").

1. Digital Goods: Instant Consumption

All Lumitone products are digital goods: AI-generated recommendation packages that are computed in real-time and delivered instantly (in-app, by email, or via a gift link). Because the product is fully consumed at the moment of delivery, and because the recommendation list itself is not stored on our servers once it has been generated and sent (gift packages excepted, as they must be retained to deliver them; and for a purchase made from an uploaded Letterboxd export we keep the derived input so the order can be delivered and shown again), a purchase cannot be "returned." What we do keep with a purchase, and for how long, is listed in section 6 of the Privacy Policy.

2. No Refund Policy

All sales are final. Except as described in Section 4, purchases are not eligible for a refund once the recommendation package has been generated and delivered.

3. EU/UK Right of Withdrawal

If you are a consumer in the EU, EEA, or UK: by completing a purchase you expressly request immediate performance of the service and acknowledge that, once the digital content has been fully delivered, you lose your 14-day right of withdrawal in accordance with applicable consumer protection law.

4. Exception: Service Interruption

Refund requests are considered only in cases of service interruption: a technical failure on our side that prevented your purchased recommendation package from being generated or delivered (for example, you were charged but received no results due to an outage).

If this happens, contact hello@lumitone.io within 14 days of the purchase, including your purchase email and the approximate time of the transaction. Verified cases receive either a re-delivery of the product or a full refund to the original payment method, at your choice. Approved refunds are processed through our payment provider and typically appear within 5-10 business days.

5. Chargebacks

Please contact us before initiating a chargeback, because verified service-interruption cases are refunded without dispute. Chargebacks filed for successfully delivered products may result in suspension of access to the Service.
