Cookie policy
This policy for gasolinerasmasbaratas.es covers cookies and similar technologies: localStorage and sessionStorage. Our storage inventory was checked against the code and the audit dated 31 October 2026, and includes the local consent preference added in this revision.
Our storage: complete inventory
The website owner is responsible for these keys. Preferences and locations are written when you use the feature you request; security and recovery markers are written when needed. They serve that technical feature or remember choices, without audience measurement or advertising profiling, and are treated as exempt from consent within that scope. The exemption does not authorise reuse for other purposes.
| Key and storage | Purpose | Retention |
|---|---|---|
combustiblelocalStorage | Your selected fuel type. | No programmed expiry; until you or your browser delete it. |
gmb-litroslocalStorage | Litres you enter for refuelling and trip comparisons. | No programmed expiry; until you or your browser delete it. |
gmb-consumolocalStorage | Manual fuel consumption or consumption applied from My car; local calculations. | No programmed expiry; until you or your browser delete it. |
gmb-favoritaslocalStorage | Up to ten favourite petrol stations: ID, name and page path. | No programmed expiry; until you or your browser delete it. |
gmb-recarga-favoritaslocalStorage | Up to ten favourite charging locations, kept separately from petrol stations. | No programmed expiry; until you or your browser delete it. |
gmb-mi-cochelocalStorage | My car profile: vehicle, consumption, connector, power and energy; no account or synchronisation. | No programmed expiry; until you or your browser delete it. |
gmb-ubicacion-cercasessionStorage | Fuel comparison origin: coordinates, accuracy, timestamp and municipality; may retain the device’s original precision. | Read as valid for 30 minutes. Expiry does not delete the record: it remains during the session or until overwritten. |
gmb-recarga-ubicacionsessionStorage | Equivalent origin for charging comparisons. | Read as valid for 30 minutes. Expiry does not delete the record: it remains during the session or until overwritten. |
gmb-recarga-orden-pendientesessionStorage | Sort order requested when opening the charging comparison: total time, distance or power. | Deleted when read; otherwise lasts for the session. |
gmb-util-sesionsessionStorage | Random ID created when attempting to vote; sent to the usefulness API, which is designed to transform it using HMAC. | Tab session; may be restored if your browser restores the session. |
gmb-util:<ruta>sessionStorage | One key per page after an accepted vote; prevents voting again in that session. | Tab session; may be restored if your browser restores the session. |
gmb-sw-recuperado-v4sessionStorage | Prevents repeated reloads when recovering a page controlled by an old service worker. | Tab session; may be restored if your browser restores the session. |
gmb-consentimiento-v1localStorage | Remembers your consent decision and when you made it; it is not an advertising profile. | Six months from the decision; you are then asked again. A new choice replaces the previous one. |
My car and favourites are not synchronised with a server. Coordinates and searches can leave your device for route calculations: see the location and routing privacy information. Closing a tab does not guarantee deletion if your browser restores sessions.
Google cookies and consent platform
| Name and provider | Purpose and condition | Retention |
|---|---|---|
FCCDCF / FCNEC | Information associated with CMP messages and choices, depending on configuration. FCCDCF was observed on 31 October 2026; FCNEC is conditional and was not observed in that test. Their names alone do not establish advertising personalisation. | Varies with the CMP, region and state. Check the actual expiry in your browser’s site data and CMP details. This is separate from the local choice’s six-month period. |
Google and authorised providers may use advertising cookies or identifiers to serve ads, limit frequency, measure results and, if you agree, personalise ads. Applicable names, providers, purposes and durations are shown in the CMP details; not every session installs the same ones. The review found no Google Analytics integration, so _ga is not listed as an installed cookie. Non-exempt cookies require prior consent.

Accepting, rejecting and withdrawing
You can accept or reject optional uses in the first layer of the notice and review purposes and providers in the consent platform. Rejecting preserves access to prices, text and tools. Silence or continued browsing does not give consent. Our own choice is remembered for six months from the decision, not from each visit.
To change or withdraw your choice, use ‘Cookie settings’ in the footer. Withdrawal stops future uses that require consent, but does not itself delete every item already processed by a provider or invalidate earlier lawful processing. You can clear cookies and site storage in your browser; this removes preferences and you may be asked to choose again.

Maps, fonts and service worker
Geist and Geist Mono are served from this domain. Maps download styles, tiles, icons and Noto Sans glyphs from OpenFreeMap: this connects to a third party even though its service states that it does not use cookies. That connection should not be confused with an advertising cookie. No first-party use of IndexedDB was identified. Service worker v4 does not intercept requests or maintain a browsing cache: it clears CacheStorage on installation and activation to recover from old versions.
