Last updated: October 2026 — drafted in accordance with EU Regulation 2016/679 (GDPR), Italian Garante Privacy Cookie Guidelines (Provv. 231/2021), and Directive 2002/58/EC (ePrivacy).
Cookies are small text files placed on your device by websites you visit. They are widely used to make websites work, improve efficiency, and provide reporting information. Similar technologies (local storage, pixels, tags) are also covered by this policy.
These cookies are essential to deliver the service you explicitly request (e.g. logging in, navigating). They are set automatically and cannot be disabled via the cookie banner.
| Cookie | Provider | Purpose | Duration |
|---|---|---|---|
omniachart_lang | OmniaChart (1st party) | Remember selected interface language | 1 year (localStorage) |
session / auth tokens | OmniaChart (1st party, on app.omniachart.com) | Authenticated session | Session / up to 30 days |
__cf_bm | Cloudflare | Bot management and DDoS protection | 30 minutes |
_omc_consent | OmniaChart (1st party, shared by omniachart.com, the app and the login pages) | Remembers whether you accepted or rejected the optional cookies, so you are asked once | 180 days |
Set only after you accept in the cookie notice. Until you choose, and if you reject, none of them is set; Google Analytics runs without cookies (Google Consent Mode v2, storage denied). Before you choose, PostHog counts only the page you view, anonymously: no cookie and nothing else is stored on your device, the count uses a hash computed on PostHog’s EU servers, no IP address is stored, and no other event is recorded (legitimate interest in aggregate audience measurement, art. 6(1)(f)). If you reject, PostHog is not loaded at all. We use IP anonymisation.
| Cookie | Provider | Purpose | Duration |
|---|---|---|---|
_ga | Google Analytics 4 | Distinguishes unique users (pseudonymous) | 2 years |
_ga_RBX7M80DZJ | Google Analytics 4 | Persists session state for the GA4 property | 2 years |
ph_<project key>_posthog | PostHog (EU Cloud) | Distinguishes visitors (pseudonymous ID) to count pages viewed and clicks towards the app | 1 year |
_omc_attr | OmniaChart (1st party) | Remembers the first page you arrived on and the link or site you came from; attached to your account if you sign up, so we know where new users come from. Never shared with advertisers | 30 days |
On omniachart.com we do not currently load any advertising or retargeting tag. The app (app.omniachart.com) may load advertising tags (Meta, Reddit, Google Ads) only after you accept; your choice is shared between the site and the app. If this changes, this policy will be updated and you will be asked again.
Some pages embed third-party content (web fonts, asset icons, images). These providers do not set tracking cookies in our integration pattern, but they may log standard HTTP request metadata (your IP and user-agent) when their resources are loaded. We disclose them in full below.

Outbound social links (X / Twitter, Instagram) are plain hyperlinks — no embedded widgets auto-load. If you click them, your browser navigates to the social network and that provider's own policies apply from that point onward.
If you reject, or until you choose, no analytics or advertising cookie is set. If you reject, PostHog is not loaded; until you choose, it only counts page views anonymously, without cookies, as described above.
You can change or withdraw your consent at any time by clicking the link below or the "Preferenze cookie" link in any page footer:
