Short version: the WBS Invoice Generator runs in your browser. What you type (your details, clients, items, invoices, logo) is stored only in your browser's local storage on your device. Wood Between Studio has no server copy, no account system and never receives it.
What's stored, and where
- Your current draft, saved documents, business details, and (Pro) clients, items and logo: in this browser's localStorage for www.woodbetweenstudio.com. They stay until you delete them in the app or clear this site's data.
- Offline copy of the app: a service worker caches the app's own files (page, scripts, fonts) so it works offline. Your invoices aren't put in that cache.
- PDFs, CSV and backup files are created on your device and saved to your downloads. They aren't uploaded.
Network connections
- Gumroad (api.gumroad.com): only if you enter a Pro license key, the app sends that key and the product ID to Gumroad's license check, and repeats the check about once a week while online. Nothing else is sent. Gumroad handles purchases under its own privacy policy.
- Cloudflare Web Analytics on the website: a cookieless counter of page views (page address, referrer, browser type, load time). It never receives what you type into the invoice generator.
- The page's security policy blocks connections to anywhere else.
Cookies and tracking
No cookies, no advertising, no fingerprinting and no cross-site tracking.
Deleting your data
Delete saved documents in the app, or clear this site's data in your browser settings, which removes everything at once. Download a backup first if you want to keep it.
Third-party code
PDFs are made with pdf-lib and @pdf-lib/fontkit (both MIT licensed) and the DejaVu Sans font (Bitstream Vera license), all served from this site: pdf-lib license, fontkit license, DejaVu license.
