Privacy policy

Last updated November 10, 2026.

Stillfield Works, a trade name of BMF Consulting Group LLC, Texas, USA, runs Facturpdf and is the controller for account data and the processor for your invoice data.

What we keep

• Early access and purchases: Polar, our merchant of record, collects your email, and for paid plans your name, billing country and payment details. We receive the email, name, country and order record. We never see your full card number.
• Invoice data (paid service): the invoices, customers and credit notes we read from your Stripe account with the restricted key you give us, the e-invoices we build, and their validation reports. Stored in EU storage.
• This website: Cloudflare, our host, keeps standard server logs (IP address, pages requested) for security. No ad trackers, no tracking cookies.

How we use it

Only to build, validate, deliver and archive your e-invoices and to run your account. We do not sell or rent any data. A data processing agreement (DPA) is available on request.

Who processes it

Polar (payments), Cloudflare (hosting, storage in the EU jurisdiction), Amazon SES (sending e-invoices to your buyers, once you turn delivery on), OpenRouter, USA (once the record-fix step is on: a language model suggests fixes for broken customer records). Only the fields being fixed are sent. OpenRouter passes them to the model DeepSeek V4.1 Flash, run by an inference host that OpenRouter lists under Zero Data Retention, meaning prompts and responses are not stored after processing. We turn on OpenRouter's zero-retention setting for every request, so a host that keeps data is never used. OpenRouter does not use inputs or outputs for model training. If we change the model or provider, this page changes first.

How long

E-invoices stay in the archive as long as you are a customer, then 12 months read-only for export, then they are deleted. Order records are kept as long as tax law requires.

Your rights

You can see, correct, export or delete your data. Use the customer portal at https://polar.sh/facturpdf/portal, or email support@facturpdf.com. We answer within 30 days.
