Cookies & storage

Essential authentication

Esmii uses secure session cookies to keep you signed in and short-lived cookies or continuations to complete sign-in, Google connection, invitations and account confirmation actions. Authentication cookies are protected from ordinary browser scripts where appropriate. Blocking essential cookies can prevent these functions from working.

Preferences

If you choose Agree in Cookie preferences, local browser storage remembers your light, dark or system theme and motion settings between visits. Before you agree, or if you choose Decline, appearance changes work in the current page but are not saved between visits. The consent decision itself is remembered on this device for 180 days. Essential authentication and security storage stays active with either choice. Session storage remembers whiteboard pan and zoom and list preferences for the current browser tab. We do not use these preferences to track you across websites.

Optional visit analytics

After you choose Agree in Cookie preferences, Esmii measures visits to registered public pages and app screens, referring website hostnames, device categories and browsers. We do not collect page query strings, complete URLs, project names, customer content or authentication links for analytics. No analytics cookie or persistent browser identifier is added. A server-calculated identifier changes each Dubai calendar day; raw IP addresses are discarded from analytics after identifier calculation. Visitor figures are daily estimates, not a count of unique people across a month. Decline or withdrawal stops browser analytics. Earlier appearance-only consent does not enable analytics; we ask again.

Aggregate service-use reporting

Separately, Esmii uses successful account verification, project creation, name contributions, Yes/No responses and the days an account opens an authorised project to report aggregate account growth, activation and return rates. These service-use totals cover accounts independently of browser analytics consent. Reports do not show individual browsing histories. Selected staff/test accounts may be excluded from future signed-in analytics. Anonymous visits and historical reports are unaffected by that setting.

Daily analytics reports are retained for 12 months and hourly detail for 30 days. Short-lived visitor and replay-deduplication records expire within 48 hours and are excluded from backups. We retain only the account dates and account/day project-use records needed for these calculations. Account deletion removes the identity link; existing aggregate and unlinked statistical counts remain until their retention period ends. We do not send visitor IP addresses to a geolocation service.

No advertising tracking

We do not use advertising cookies or session-recording technology. Google and your email provider process activity on their own services under their policies when you choose to use them.

Your controls

Use Cookie preferences in the footer or Settings to change your decision at any time. Declining removes saved theme and motion preferences without signing you out. You can also remove cookies or stored data through your browser; clearing authentication storage signs you out. Contact support@polytech.ae for questions.
