Cookie Policy
Last updated September 2026
Cookies are small text files that a website stores on your device when you visit. This policy explains which cookies TaxFly uses, who sets them, why, how long they last and how you can control them. TaxFly is operated by Radiant Vibes Ltd (company number 17082185). This policy should be read alongside our privacy policy.
Your choice
If you are in the UK, the EEA or Switzerland, we ask before setting any cookie that is not strictly necessary. The consent message is provided by Google and is certified under the IAB Europe Transparency & Consent Framework, so you can accept, refuse, or choose purpose by purpose and vendor by vendor. Nothing in the analytics or advertising rows below is set until you have made that choice.
You can change your mind at any time with the Cookie settings link at the foot of every page.
Strictly necessary cookies
These make the site work and cannot be switched off. They do not track you.
| Cookie | Set by | Purpose | Lasts |
|---|---|---|---|
taxfly_session | TaxFly | Keeps you signed in, if you have an account. | 30 days |
tf_oauth_state, tf_oauth_verifier, tf_oauth_next | TaxFly | Protect the "Sign in with Google" step against forgery. | Minutes, until sign-in finishes |
portal_sidebar | TaxFly | Remembers whether you collapsed the dashboard menu. | 1 year |
FCCDCF, FCNEC | Store the consent choice you made, so you are not asked on every page. | Up to 13 months |
The answers you give in our checks are kept in your browser's local storage rather than in a cookie. They stay on your device and are never sent to us unless you create an account.
Analytics cookies
Only with your consent. They tell us which calculators and guides people use, and where pages are confusing or broken, so we can improve them. Microsoft Clarity and Yandex Metrica record how the page is used — clicks, scrolling and mouse movement — as a session replay.
| Cookie | Set by | Purpose | Lasts |
|---|---|---|---|
_ga, _ga_* | Google Analytics | Distinguish visitors and sessions so visits can be counted. | Up to 2 years |
_clck, _clsk, CLID, MUID | Microsoft Clarity | Link the pages of one visit into a single session replay and heatmap. | Up to 1 year |
_ym_uid, _ym_d, _ym_isad, _ym_visorc | Yandex Metrica | Count visits and link the pages of one visit into a session replay. | Up to 1 year |
Advertising cookies
TaxFly is free because it carries ads, served by Google AdSense and Google Ad Manager.
| Cookie | Set by | Purpose | Lasts |
|---|---|---|---|
__gads, __gpi, __eoi | Limit how often you see the same ad, measure ads and prevent fraud. | Up to 13 months | |
IDE, DSID, test_cookie | Google (doubleclick.net) | Show ads based on your interests and measure how they perform. | Up to 13 months |
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to TaxFly and/or other sites on the Internet.
- You may opt out of personalised advertising by visiting Google's Ads Settings, or opt out of some third-party vendors' cookies at www.aboutads.info or www.youronlinechoices.com.
If you refuse advertising cookies you still see ads, but they are not personalised. Google's list of cookies and what each does is in How Google uses cookies.
Managing cookies in your browser
As well as the consent message, every major browser lets you block all cookies, block third-party cookies, or clear cookies already stored. Blocking the strictly necessary cookies will stop sign-in from working.
Changes to this policy
If the cookies we use change, we will update this page and the "last updated" date at the top.
