Cookie Policy
The cookies and local storage this website uses, and how to control them.
Last updated: 29 July 2026 · Version 1.0.
Who we are
This policy is published by LinkTrail Ltd, a company registered in England and Wales, company number 17312947, registered office 66 Paul Street, London EC2A 4NA, United Kingdom. We are the controller for the data described here. Questions: privacy@linktrail.io.
This policy covers linktrail.io and developer.linktrail.io only. The data our SDKs and link endpoints collect inside our customers' mobile apps is a different matter entirely, governed by each customer's own privacy notice and described in Section 5 of our Privacy Policy.
How we use cookies
We store one strictly necessary value to remember your consent choice. That value is set regardless of your choice, because it is what records the choice.
Only if you accept do we set:
- Google Analytics for Firebase cookies, to measure how the website is used, and
- a Google Ads cookie, to measure whether an ad click led to a signup.
We use the Google Ads cookie for conversion measurement only. We do not use it for remarketing or personalised advertising, and we run no other advertising cookies.
Managing your choice
Our banner offers Accept and Reject with equal prominence. Rejecting takes one click and is no harder than accepting. Nothing beyond the strictly necessary consent value is set until you accept — analytics and advertising tags are blocked until then, not merely ignored.
You can change your decision at any time using "Cookie settings" in the footer of any page, or by clearing site data in your browser. Withdrawing consent is as easy as giving it.
How long your choice lasts. We will ask you again after 6 months, so that a choice you made once does not bind you indefinitely. We record the version of this policy in force when you chose, so we can tell whether your consent covers our current practices.
Cookies and local storage we use
| Name | Provider | Type | Purpose | Duration |
|---|---|---|---|---|
| lt-consent | LinkTrail | Local storage | Records your consent choice and the policy version it was given under | 6 months, then we ask again (strictly necessary) |
| _ga | Cookie | Distinguishes users | 2 years (set only after consent) | |
| _ga_* | Cookie | Persists session state | 2 years (set only after consent) | |
| _gcl_au | Cookie | Links an ad click to a later conversion — measurement only, no remarketing | 90 days (set only after consent) |
Cookie lifetime is not the same as data retention. The _ga cookies persist on your device for 2 years. How long Google retains the analytics data itself is set on our analytics property; contact privacy@linktrail.io for the current setting.
Where this data goes
Accepting analytics means data is transferred to Google, whose processing for these services takes place in the United States. That transfer relies on the ICO's International Data Transfer Agreement or the EU Standard Contractual Clauses with the UK Addendum, supported by a transfer risk assessment. It happens only if you accept, and you can withdraw at any time.
Further detail on transfers is in Section 8 of our Privacy Policy.
Your rights and complaints
Consent is our lawful basis for the analytics and advertising cookies (PECR regulation 6 and UK GDPR Article 6(1)(a)). You can withdraw it at any time, and you have the rights set out in Section 11 of our Privacy Policy — including access, erasure and objection.
If you are unhappy with how we handle cookies, contact us at privacy@linktrail.io. You can also complain to the Information Commissioner's Office at ico.org.uk or on 0303 123 1113.
Changes
We update this policy when our cookies or the law change. The version number and date above always reflect the current version. Where a change means your existing consent no longer covers what we do, we will ask you again rather than rely on the old choice.
