Cookies and browser storage

Version of 20 October 2026.

1. In short

Before consent, the Google tag sends only cookieless measurement pings without browser identifiers and sets no Analytics cookies. After you answer the consent request, layers.md sets one cookie with your answer (layers_consent) so that app.layers.md respects it too. If you allow “Analytics”, Google Analytics 4 (Google Ireland Ltd.) uses the cookies listed below to count visits and conversion steps. Personalised advertising is off. Separately, pages with calculators and documents send anonymous step events to our own server app.layers.md — the type of step, the page and the source label. These events contain no name, email or anything you type.

On your first visit the site shows a bar with a choice: “Accept all”, “Reject” or “Customize”. Before you allow Analytics, Google receives cookieless measurement pings with consent state and event type, without browser identifiers; accepting enables full measurement and its cookies. The “Third-party media” category is used for demo videos hosted on YouTube. Until you start playback and agree, no YouTube request is made. After you agree, the video loads from youtube-nocookie.com and Google receives your IP address. You can withdraw consent at any time via “Cookie settings” in the footer.

2. What is stored in your browser

Your browser keeps only your own choices in local storage (localStorage):

layers-theme — colour theme: light or dark. Saved when you switch the theme.

layers-lang — code of the chosen site language: en, ru, es or another from the site’s language list. Saved when you switch the language.

layers-consent — your answer to the consent request: allowed categories, rules version and date. This is the record of consent (Art. 7(1) GDPR). Saved when you press a button in the bar or in cookie settings.

layers_consent — copy of your answer to the consent request for the app at app.layers.md: whether analytics is allowed and the rules version. Set only after you press a button; expires after 1 year.

_ga — Google Analytics, only with consent to “Analytics”: distinguishes visits; expires after 2 years.

_ga_HS2CM8JWRM — Google Analytics, only with consent to “Analytics”: keeps the state of the current visit; expires after 2 years.

These values are never sent to our server or anyone else, contain no identifiers and cannot be used to identify you. They have no expiry: they stay in your browser until you delete them. We ask for consent again only if the rules change.

Until you make a choice, nothing is stored: the site follows your system theme and opens in the language of the address (/, /ru/, /es/); the default language is English.

3. How to change your choice

Open cookie settings — the link is also in the footer of every page. Withdrawing consent is as easy as giving it.

4. Why this needs no consent

Remembering a setting you explicitly chose, and your answer to the consent request, is needed to carry out your own request. Such storage does not require consent: Art. 5(3) of Directive 2002/58/EC, Art. 22.2 of the Spanish LSSI-CE, and the AEPD cookie guide (user-chosen interface settings).

5. How to delete it

Clear the site data for layers.md in your browser settings, usually under Privacy → Cookies and site data. The site will then follow your system settings again.

6. The app and other sites

The “Sign in” and “Start free” buttons lead to the app at app.layers.md. The app has its own rules, described in the Privacy Policy.

Links to the App Store, Google Play, Docker Hub and sumoffice.com lead to other companies’ sites. Nothing is sent to them until you follow a link.

7. Changes

If we add other services that require consent, we will update this page and ask for consent before turning them on. Questions: contacts@layers.md.
