LudeInvoice is a free, no-account web tool for generating invoice and offer PDFs. This page explains what happens to your data when you use it.
The short version
We do not collect, store, transmit, or process any of your data on our servers. LudeInvoice has no backend. Everything you type — invoice details, client info, line items, logos — stays entirely inside your web browser on your device.
What is stored locally
To make the app useful, we save your current draft to your browser's localStorage. This includes:
- The invoice/offer content you typed (seller details, buyer details, line items, notes).
- Any logo image you uploaded (as a base64 data URL).
- Your theme and document-format preferences.
This data never leaves your device. It is not transmitted to LudeHQ or any third party. It persists only in your browser, and you can clear it at any time by clicking Reset in the toolbar, by clearing your browser's site data for this domain, or by using your browser's incognito/private mode.
What we do not collect
- No account creation, no email, no password.
- No analytics, tracking pixels, or third-party trackers.
- No advertising cookies or marketing identifiers.
- No server logs of your invoice content (we have no server).
Cookies
LudeInvoice does not set any cookies. The browser localStorage we use is a separate web-storage mechanism that is local to your device and is not transmitted with HTTP requests.
Third-party resources
The app loads a small number of static resources from third-party CDNs:
- Google Fonts (
fonts.googleapis.com,fonts.gstatic.com) — for the editorial typefaces. - jsDelivr (
cdn.jsdelivr.net) — for the fonts embedded in generated PDFs.
These providers may log your IP address as part of normal HTTP requests, governed by their own privacy policies. We have no influence over and receive no data from these requests.
PDF downloads
When you click Download PDF, the PDF is generated entirely inside your browser and saved directly to your device. The file is not uploaded to or processed by any server.
Children
LudeInvoice is not directed at children under 13. We do not knowingly collect any data from anyone, including children.
Changes to this policy
If this policy changes, we will update the "Last updated" date at the top of this page. Material changes will be highlighted in the app interface.
