Privacy Policy
Last updated: 19 September 2026
1. Guiding principles
Your privacy is very important to us. This Privacy Policy explains the steps we take to protect your personal data, the information we collect, the purposes for which we use it, the legal bases on which we rely, how long we keep it, and the rights you have under the General Data Protection Regulation (EU) 2016/679 (“GDPR”) and Organic Law 3/2018 on Personal Data Protection and Guarantee of Digital Rights (LOPDGDD).
The website https://www.stemeditor.com (the “Website”) is operated by Alexander Comely, self-employed professional (autónomo), NIF X4942814E, with registered address at Carrer Unic 3, Clua de Meià, Artesa de Segre 25737, Spain (hereinafter “we”, “us” or “STEM Editor”).
Our processing of personal data is governed by the laws of Spain and by the GDPR. This Privacy Policy forms part of our Terms and Conditions and should be read together with them. We never sell personal data about our clients to anyone.
2. Data controller

Name: Alexander Comely
NIF: X4942814E
Address: Carrer Unic 3, Clua de Meià, Artesa de Segre 25737, Spain
Email: info@stemeditor.com
We have not appointed a Data Protection Officer (DPO) because we are not required to do so under Article 37 GDPR or Article 34 LOPDGDD.

Depending on how you interact with us, we may process the following categories of personal data:
3.1 Data you provide when you contact us or place an order

3.3 Payment-related data
When you pay via PayPal (including credit/debit card payments processed through PayPal), we do not receive or store full card numbers, CVV codes or bank-account details. PayPal processes those data as an independent controller under its own privacy policy. We only receive confirmation of payment, the amount, currency, transaction ID and the billing name/email associated with the payment.

5. Recipients and processors
We do not sell or rent personal data. We share data only with the following categories of recipients, and only to the extent necessary.

Contract editors: freelance editors who perform the proofreading/editing work. They receive only the documents necessary to complete the assignment and are bound by written non-disclosure and data-protection obligations. Identifying customer data (name, email, address) is not shared with editors unless strictly required.
Hosting and email providers: the companies that host the Website and provide email services. They act as processors under appropriate contractual safeguards.
Tax and accounting advisers (gestoría): only the data required for invoicing and tax compliance.
Competent authorities: when we are legally required to disclose information (e.g. tax authorities, courts, police).
We do not transfer personal data outside the European Economic Area except where the recipient is covered by an adequacy decision, Standard Contractual Clauses, or another valid transfer mechanism under Chapter V GDPR (for example, Jotform’s EU–US Data Privacy Framework participation or SCCs).

Order, invoicing and tax records: retained for the periods required by Spanish tax and commercial law (generally 4–6 years after the end of the relevant financial year).
Enquiry correspondence: retained for as long as needed to handle the enquiry and for a reasonable period thereafter (normally up to 2 years) unless a longer period is required for legal claims.
Server logs and technical data: normally retained for a short period (typically 30–90 days) for security and diagnostic purposes.

8. Cookies and similar technologies
A cookie is a small file of letters and numbers that we store on your browser or device. We use first-party and third-party cookies, pixels and similar technologies.
8.1 Strictly necessary cookies
These cookies are essential for the Website to function (for example, to maintain a session or to remember cookie-consent choices). They do not require consent under Art. 22(2) LSSI-CE.
8.2 Analytics and other non-essential cookies
We may use analytics tools (for example Google Analytics or equivalent) to understand how the Website is used. These cookies are set only if you give prior consent via the cookie banner. You may refuse or withdraw consent at any time without affecting the basic functionality of the Website.
You can also control cookies through your browser settings. Useful information is available at www.allaboutcookies.org. Disabling certain cookies may affect site performance.
9. Security measures
We implement appropriate technical and organisational measures to protect personal data against unauthorised access, loss, destruction or alteration. Order forms and file uploads are transmitted using SSL/TLS encryption (normally 256-bit or higher). Documents are stored only for the time needed to perform the service and are then securely deleted. Contract editors are bound by confidentiality obligations. No method of transmission or storage is completely secure; you remain responsible for the security of your own devices and for any residual copies you keep.
10. Minors
Our services are directed at adults and businesses. We do not knowingly collect personal data from children under 14. If you believe a child has provided us with personal data, please contact us so that we can delete it.
