2. What you buy
A digital copy of 50 Years Until the End: the e-book in EPUB and PDF format (6.99 €), the audiobook in M4B and MP3 format (9.99 €), or both together (12.99 €), for your personal, non-commercial use. The price is shown before you pay. You may not share, resell or publish the files. All rights to the text belong to the author. The audiobook is narrated by an AI-generated voice.
3. Payment and delivery
You pay by card on the secure payment page of Revolut. We never see or store your card details. Once Revolut confirms the payment, the download page opens and we email you its link. The link lets you download the files several times. You also receive an invoice.
4. Right of withdrawal
Under EU and Bulgarian consumer law you normally have 14 days to withdraw from an online purchase. For digital content that is delivered immediately, this right ends once delivery begins, if you agreed to that beforehand. When you buy, you ask for immediate delivery and confirm that you lose the right of withdrawal once the download becomes available. If the files are faulty or cannot be downloaded, write to us and we will fix it or refund you.
5. Your data
The controller of your data is Вавилон Бизнес Мениджмънт ООД. For each order we keep your name, email, country, optional company details, the order and payment reference, the time of your consent and the IP address it came from, and a count of downloads. We use them to deliver the e-book, issue the invoice, answer your questions and meet accounting obligations. Accounting records are kept for the period Bulgarian law requires (generally 10 years).
Processors: Revolut (card payment), Cloudflare (website hosting, email delivery and file storage in the EU). We do not sell your data or use it for advertising.
You may ask for access to your data, its correction or deletion (where the law allows), or object to its use, by writing to the contact above. You may also complain to the Bulgarian Commission for Personal Data Protection (cpdp.bg).
6. Contact form
When you write to the author through the contact form, your name, email and message are sent by email to the author's mailbox, so that he can answer you. We keep a one-way code of your IP address for a short time to stop spam. Nothing from the form is published.
7. Complaints and disputes
Write to us first; we answer within 14 days. Bulgarian law applies, without removing the protection your own country's consumer law gives you. You can also use the Bulgarian Commission for Consumer Protection (kzp.bg).
