This policy explains exactly what the VAT Invoice Generator browser extension does and does not do with your data. It is written to match how the extension actually behaves.
The only data the extension processes is the invoice you create —
seller details, client details, line items, notes, your logo,
templates and preferences. This stays in your browser's local
storage (chrome.storage) on your own device. It is not
transmitted to us or to any server as part of normal use, and we have
no ability to see it.
The extension makes outbound network requests in exactly two cases, and never otherwise:
extensionpay.com (ExtensionPay) to check your
subscription status and to open the checkout / manage pages.
Payment is processed by ExtensionPay and Stripe under their own
terms and privacy policies. The ExtensionPay library stores a small
licence/installation token in your browser's synced
storage (chrome.storage.sync) so your Pro status follows
your Chrome profile across devices; your invoice content is never
synced or transmitted. Your invoice content is never sent —
only subscription/account status is checked. See
ExtensionPay's privacy policy
and Stripe's privacy policy.ec.europa.eu so it can be checked against
the EU register. This is best-effort, may be unavailable, is never
automatic, and never blocks creating an invoice. Only that VAT
number is sent — no other invoice content. Please do not use this
to look up numbers you are not entitled to check.This is a business tool for invoicing and is not directed to children.
Because invoice data lives only in your browser's local storage, you control it entirely. Removing the extension, or clearing the extension's storage from your browser, deletes it. We hold no copy. For subscription data held by ExtensionPay/Stripe, refer to their policies linked above and their account/cancellation controls.
If the extension's data behaviour changes, this page will be updated and the "last updated" date changed. Material changes will be reflected in the extension's listing.
