Offertje is made by Agensea in the Netherlands. Jorik Schut is your contact for purchases, questions and corrections at jorik@agensea.nl. The editorial team uses AI assistance for some content; examples are checked arithmetic, not claims of local market research or personal tax advice.
Calculator values stay in your browser. A quote draft may be saved in browser storage. If you share a computer, clear the saved draft when finished. When you buy a PDF, the quote is processed by our Vercel-hosted server to bind the purchase to that version and generate the file. There is no central quote archive. Download and save your purchased file.
Stripe processes payment details. We do not receive your full card number. The download price is charged in EUR; your bank may apply currency-conversion costs. Payment and administration records may be retained to fulfil purchases and legal record-keeping obligations. Quote contents are not included in payment metadata.
Vercel Web Analytics and our Radar collect page paths, referring sites, device type, broad region and fixed actions such as using a calculator or starting checkout. We do not send entered amounts, quote text, customer names or URL query parameters. We do not use a persistent visitor identifier. IP information is used to count visits per day and is not stored as a readable IP address. Statistics are retained for at most 13 months. Do Not Track and Global Privacy Control disable our tracking.
International pages do not load advertising scripts. Where a partner link is used, the page identifies it. Following a link transfers you to the provider or its affiliate network, whose own privacy policy applies. A commission does not make that provider the best choice for you.
For data access, correction, deletion or other applicable privacy rights, contact jorik@agensea.nl. You can delete browser-only data in your browser settings. You can lodge a complaint with the Dutch data protection authority. Our download support uses email; do not send full card details or confidential client documents.
Usage statistics for paid downloads
To improve the editor, our weekly totals count paid downloads with 1–3, 4–9 or 10 or more line items, and how often a discount or a recurring item is used. These counts contain no prices, text, customer details or payment references. Downloading again can add to the counts.
