What cookies are#
A cookie is a small text file that a website stores on your device and that is sent back with your next request. Cookies are used, among other things, to keep you signed in and to remember a choice you have made.
First-party cookies are set by invoia.io and can only be read by invoia.io. Third-party cookies are set by a domain other than the one you are visiting.
Session cookies are deleted when you close your browser. Persistent cookies stay until they expire or until you delete them. Our sign-in cookie is persistent, with a lifetime of 400 days. It is not a session cookie.
Similar technologies#
In addition to cookies we use browser storage (localStorage) in exactly one place: to remember your cookie preference. Entries in localStorage have no expiry, and none is set. They stay until you change your choice or clear your browser data.
We do not write to sessionStorage or indexedDB, and we use no service worker.
On /sign-in and /register a device check also runs. It reads technical characteristics of your browser — screen resolution, fonts and canvas rendering among others — and computes a device identifier from them. The computation itself happens in your browser, and neither the characteristics nor the device identifier is sent to a third party. The library we use for the computation occasionally sends an anonymous usage request to the vendor's own domain (m1.openfpcdn.io); that request contains no information about you beyond your IP address and browser identification. The identifier is sent to our own server together with the sign-in and registration request. As part of the check, a cookie named cookietest is written and immediately expired again, to test whether cookies are enabled at all.
No cookie banner is shown on /sign-in or /register.
What we do not use#
- No Google Analytics. There is no Google Analytics, no Google Tag Manager and no analytics service other than the one listed in the inventory below.
- No marketing, advertising or retargeting cookies and no advertising pixels. We share no information with advertising networks.
- No cross-site tracking and no profiling for marketing purposes.
- No fonts fetched from Google. Fonts are bundled when the site is built and served from our own domain, so your browser sends no request to Google to fetch them.
