Necessary storage
The HTTP-only authentication session lasts up to 30 days. The versioned privacy preference lasts 6 months. Functional chat and local preferences expire after 30 days of inactivity. The FX cache lasts 6 hours.
External maps
Mapbox is optional. Before active consent we do not load its JavaScript, CSS, imagery or telemetry, and it cannot create browser storage. Text search and RÚIAN verification remain available. Consent can be withdrawn at any time.
Analytics and advertising
Analytics and advertising identifiers are stored only after separate consent. We may record allow-listed UTMs, click IDs, locale, campaign, audience and aggregate outcomes. If you send your contact details after clicking an ad, we share the click ID with Google Ads or Meta and, for Meta, a hashed (SHA-256) email and phone, to measure which ads bring enquiries. The complete Advisor works without consent or advertising identifiers.
