Cookie Policy

Last updated: 20 July 2026 · Effective immediately

This Cookie Policy explains which cookies and similar technologies RegSpecs ("we", "us", "our"), operated by MD Data Source Ltd, uses on regspecs.com, what they do, and how you can control them.

You can review or change your choices at any time: . For how we handle personal data more broadly, see our Privacy Policy.

1. What Are Cookies?

Cookies are small text files that websites store on your device to remember information between visits. We also use similar technologies such as browser local storage, which this policy covers under the same rules.

Cookies are grouped by purpose: some are essential for the website to work, while others measure how the site is used or help us understand which advertising brought you here.

3. Strictly Necessary Cookies

These are required for the website to function — signing in, paying securely, and remembering your region and consent choices. They cannot be switched off.

CookieProviderPurposeDuration
c15tRegSpecsStores your cookie consent choices so we do not ask again on every visitUp to 12 months
REGSPECS_LOCALERegSpecsRemembers your market and language preference (UK or Ireland)Up to 13 months
better-auth.session_token (and related sign-in cookies)RegSpecsKeeps you signed in to your accountUp to 7 days
__stripe_midStripeFraud prevention and payment security during checkoutUp to 1 year
__stripe_sidStripeFraud prevention and payment security during checkout30 minutes

Stripe cookies are set when you visit our checkout pages. Stripe processes payments on our behalf and uses these cookies solely for payment security and fraud prevention.

4. Analytics Cookies

With your consent, we use PostHog (hosted in the EU) to understand how visitors use the site — which pages are visited and which features are used — so we can improve it.

CookieProviderPurposeDuration
ph_phc_* (PostHog)PostHog (EU)Product analytics: pages visited, feature usage, and session continuityUp to 12 months

If you reject analytics cookies, PostHog stores nothing on your device. We then only receive anonymous, aggregated statistics that cannot be linked to you or to your activity across visits.

5. Advertising Cookies

We advertise RegSpecs on search engines. With your consent, these cookies let us measure whether an advert brought you to the site and whether it led to a purchase. They are set only after you accept advertising cookies:

CookieProviderPurposeDuration
rs_attrRegSpecsFirst-party record of which advert click brought you to the site (for example a Google or Microsoft click reference), so a later purchase can be attributed to it90 days
_gcl_au, _gcl_aw and related Google cookiesGoogleLinks Google Ads clicks to purchases so we can measure advertising performanceUp to 90 days
MUID, _uetsid, _uetvidMicrosoftLinks Microsoft Advertising clicks to purchases and supports remarketing (only used if we run Microsoft advertising)1 day to 13 months

If you reject advertising cookies, none of the above are stored. Google may still receive cookieless, non-identifying signals (Google Consent Mode) that let it estimate advertising performance in aggregate without identifying you or your device.

Where we report a purchase to an advertising platform, contact details are protected with one-way hashing and are only shared for purchases made after you accepted advertising cookies.

6. Tools That Do Not Use Cookies

We use Sentry for error monitoring so we can detect and fix faults with the website. Sentry does not store cookies or other data on your device; error reports are sent directly from the page when something goes wrong.

7. Managing Your Cookies

You are in control of all non-essential cookies:

  • Use the consent banner shown on your first visit to accept, reject, or customise
  • Change your mind at any time via the Cookie preferences link in the page footer
  • Delete or block cookies through your browser settings (blocking strictly necessary cookies may stop parts of the site working, such as sign-in and checkout)

Withdrawing consent takes effect immediately: the related cookies stop being used and consent-dependent cookies we set ourselves are deleted.

8. Changes to This Policy

We may update this Cookie Policy from time to time — for example if we add or remove a tool.

Any updates will be posted on this page with a revised "Last Updated" date.
