Terms of Service
Last updated: 3 July 2026 · getoptical.app
These Terms govern your use of the Shopify apps and services provided by Carlos Enrique Herrera Betancourt, a sole trader (autónomo) with Spanish tax ID (NIF) 54263611X, trading as "Optical" ("Optical", "we"), with address at Calle Arroyo 27, 41003 Seville, Spain. By installing or using an app, you agree to these Terms.
1. The service
Optical provides Shopify apps — including Optical Form — that let merchants offer prescription-eyewear and lens configuration on their store. We may update, improve or change features over time.
2. Plans, billing & free trial
Paid plans are billed through Shopify's Billing API and appear on your Shopify invoice. Plans include a 14-day free trial; you can cancel before it ends to avoid charges. We charge a flat plan price and take no commission on your sales. You can upgrade, downgrade or cancel from within Shopify at any time.
3. Acceptable use
You agree to use the apps lawfully, not to misuse or attempt to disrupt the service, and to be responsible for the accuracy of prescription data collected through your store and for any regulatory obligations that apply to selling optical products in your market.
4. Intellectual property
Optical retains all rights to the apps and their code. You retain all rights to your store, content and customer data.
5. Disclaimers
The service is provided "as is". Optical is a software tool and does not provide medical or optometric advice; merchants are responsible for the validity of prescriptions and for fulfillment.
6. Limitation of liability
To the extent permitted by law, Optical is not liable for indirect or consequential damages. Total liability is limited to the fees paid in the 12 months before the claim.
7. Termination
You may uninstall at any time. We may suspend access for breach of these Terms.
8. Data protection (data processor)
Where the app processes personal data of a merchant's customers (including prescription data, which may be special-category data), the merchant is the data controller and Optical acts as processor, processing such data only to provide the service and on your documented instructions. As processor (Art. 28 GDPR) we: (a) process data only under these Terms and your instructions; (b) ensure confidentiality; (c) apply appropriate security measures (TLS encryption, restricted access); (d) use the sub-processors listed in the Privacy Policy (Shopify, Gadget); (e) assist you with data-subject requests and breaches; and (f) delete or anonymize the data when the service ends, honoring Shopify's mandatory redaction requests. This clause constitutes the data-processing agreement between the parties; if you need a separately signed DPA, contact us.
9. Changes & governing law
We may update these Terms; continued use means acceptance. These Terms are governed by Spanish law, and the GDPR (EU) 2016/679, the LOPDGDD (Organic Law 3/2018) and the LSSI-CE (Law 34/2002) apply. Any dispute shall be submitted to the courts of the provider's domicile, unless a mandatory rule provides otherwise.
