Privacy Policy (GDPR): Who we are: MathGraphicaArt ("we", "us", "our") sells digital art downloads on Etsy. For EU/UK data protection law, we are the data controller for personal data we receive via Etsy Messages, orders, and email. What data we collect: identity and contact (name, Etsy username, email address, and, if provided, billing/region info); order details (items purchased, timestamps, transaction IDs, VAT/tax information where applicable); communications (messages you send us on Etsy or by email). We do not receive your payment card data; payments are processed by Etsy and its processors. Why we use your data (legal bases): contract (to fulfill your order, provide downloads, and customer support); legal obligation (to meet tax/accounting and consumer-law requirements); legitimate interests (to run and protect our shop, for example fraud prevention and record-keeping, and to improve our offerings); consent (only if you ask us to send off-Etsy marketing; you can withdraw consent at any time). Sharing your data: we share data only as needed to run the shop - Etsy (independent controller) provides the platform and delivers your files; email and cloud providers (processors) handle customer support and secure storage. We do not sell your personal data. International transfers: we are based in the USA, and our service providers may process data in other countries; where required, we use appropriate safeguards (for example, standard contractual clauses) and limit access to what is necessary. Retention: order and transaction records are kept for 7 years (tax/accounting); messages and support records are kept for up to 2 years or as needed to resolve issues; we will delete or anonymize data sooner if the law allows and we no longer need it. Your rights (EU/UK): you may request access, correction, erasure, restriction, portability, or object to processing based on our legitimate interests; you also have the right to lodge a complaint with your local data protection authority; we respond to rights requests within one month. Children: our products are not directed to children, and we do not knowingly collect personal data from anyone under 16. How to contact us: for privacy questions or requests, contact us via Etsy Messages. Data Controller: MathGraphicaArt, USA. Changes: we may update this policy to reflect operational or legal changes; the latest version will always appear here. Effective date: 2025-09-06.
