How PDFBildr, on the web, Windows, iPad and iPhone, handles your information. Last updated November 11, 2026.
Who we are
PDFBildr is run by Anker Advisory Group, 252 NW 29th St #9, Miami, FL 33127, United States. Questions: admin@ankeradvisors.com.
Without an account
You can use PDFBildr without signing in. Then your PDFs, markups and signatures stay on your device, or in your own Google Drive or OneDrive if you connect one. We don't receive them. Reading the text on scanned pages happens on your device.
When you sign in
With an account we keep:
- Your name and email address, and your company if you work on a shared project.
- Your settings, your saved signatures and your digital IDs. A digital ID is stored encrypted with a password only you know; we can't open it.
- Whether you have PDFBildr Pro.
- On a shared project: the documents added to it, and the markups, measurements, comments and photos people add. Photos have their location removed on your device before they're uploaded.
We don't use your information for advertising, we don't track you across other apps or websites, and we don't sell it.
Why
Only to run PDFBildr: to sign you in, keep your settings and signatures on all your devices, let the people on a project work on the same documents, and answer you when you write to us.
Who handles it for us
- Supabase keeps the database and stored files, in the United States (US East).
- Vercel hosts this website and the web app.
- Google and Microsoft, if you sign in with them or connect your Drive or OneDrive: they confirm who you are, and the app reads and saves the files you choose there.
- Apple, for the iPad and iPhone app and for Pro bought through the App Store. If you allow it, Apple shares crash reports with us.
- Anthropic, only if you use AnkerAI features (such as building a submittal register from a spec book): the text of the pages you send is processed to produce the answer and isn't used to train their models.
These companies handle the information only to provide their service to us.
On your device
The apps keep the documents you open, your markups and changes waiting to be sent on your device. On the iPad, your sign-in is in the Keychain. Signing out removes the copies of shared projects from the device; PDFs you opened from your own files stay where they are.
How long we keep it
Your account and what you've stored with it stay until you ask us to delete them. Documents on a shared project are kept for as long as that project needs them.
Your choices
To see what we hold about you, correct it, or have your account and its data deleted, email admin@ankeradvisors.com from the address you signed in with. We reply within two business days.
Children
PDFBildr is a work tool and isn't meant for children under 13.
Changes
If we change how we handle your information, we'll update this page and its date, and tell you in the app if the change matters to you.
