Cookies and similar technologies
Last updated: 18 May 2026
This document describes how billo.ge uses browser cookies, local storage and similar technologies. For a full description of personal data processing, see the privacy policy.
1. What an HTTP cookie is
A cookie is a small text record that a website (or a subdomain of it) stores in your browser and that the browser automatically sends back to the server with the relevant requests. A cookie can be session (deleted when the browser is closed or after a short time) or persistent (until a certain date or until you delete it yourself).
2. Why we need cookies
The platform is built on a standard web architecture (Django). Most features (signing in, saving invoices, the API) require a secure session and CSRF protection – both traditionally rely on cookies.
3. Cookies used by the platform (first party)
The names below are typical for Django; the exact names may differ depending on the configuration.
| Name (typical) | Type | Purpose | Duration |
|---|---|---|---|
sessionid |
Strictly necessary | Authenticated session – who you are and which account is active. | Session / set by configuration |
csrftoken |
Strictly necessary | Protection against Cross-Site Request Forgery – security of forms and JSON POST requests. | Session or several months (depending on settings) |
billo_language |
Functional | Remembers the interface language you selected. | 1 year |
Disabling or deleting these cookies may make it impossible to sign in, cause “403/CSRF” errors or prevent invoices from being saved.
4. Similar technologies: localStorage and sessionStorage
The platform may use the browser's localStorage or sessionStorage – these are not HTTP cookies, but they are similar in that data is stored on your device. They are typically used for:
- temporarily saving an invoice draft – so that you don't lose entered text when the page reloads;
- interface settings (e.g. the last selected company or the theme) – where implemented.
This data is not sent to the server automatically until you save an invoice or perform another action.
5. Third-party resources and cookies
5.1. Google Fonts (fonts from an external CDN)
If a page loads fonts from Google Fonts, your browser contacts Google's servers – your IP may be transmitted and cookies may be set in accordance with Google's policy. Details: Google Privacy, Google Cookies.
5.2. Sign in with Google (OAuth)
If you use “Continue with Google”, the authentication process opens on Google's domain, where Google's cookies and terms apply. billo.ge receives only the information you agree to share via the OAuth protocol.
6. Analytics
billo.ge uses Google Analytics 4 (GA4) to collect statistics on visits and platform usage. GA4 may set cookies (e.g. _ga, _ga_*) and obtain your IP address, browser/device information, pages viewed and actions (e.g. PDF downloads). IP anonymisation is enabled.
Data is processed in accordance with the policies of Google Ireland Limited / Google LLC: Google Privacy, Google Cookies. You can disable analytics cookies in your browser settings or with the Google Analytics Opt-out add-on.
We do not use advertising retargeting networks' own tracking cookies. If other analytics or marketing cookies are added in the future, this page will be updated.
7. How to manage cookies on your side
All modern browsers let you view, delete and block cookies. Instructions: Chrome, Firefox, Safari, Edge – the “Privacy” / “Cookies” section of the settings. Note: blocking all third-party cookies may break Google OAuth or font loading.
8. Do Not Track (DNT)
A DNT signal from the browser does not change our strictly necessary technical cookies by default, as they are essential for the service. If optional tracking is added in the future, we will consider supporting DNT in line with industry practice.
9. Changes
When the policy is updated, the date at the top will change. For significant changes there may be an additional notice on the platform or by email.
For questions, see the privacy policy and the terms of use. This is a translation; in case of discrepancies, the Georgian version prevails.
