01The short version

Lensym only uses cookies that are strictly necessary for the Service to work: signing you in, keeping your session secure, and protecting against attacks.

What you won’t find here

  • No advertising or marketing cookies
  • No third-party tracking or analytics cookies
  • No cross-site tracking of any kind
  • No cookie consent banner — because there is nothing to consent to

Because we only use strictly necessary cookies, EU law (the ePrivacy Directive) does not require us to ask for consent before setting them.

02Cookies we set

All cookies below are first-party, set by Lensym itself. They are marked HttpOnly and Secure where applicable, so they cannot be read by scripts or sent over insecure connections.

Session token

7 days, refreshed while you use the Service

Keeps you signed in to your account securely

Session cache

Up to 7 days

Avoids re-checking your session on every request, keeping the app fast

Two-factor challenge

Minutes — removed once sign-in completes

Remembers that you are mid-way through two-factor sign-in

Security (CSRF) protection

Session

Protects forms and requests against cross-site request forgery

03Cookies and survey respondents

People answering a survey do not need an account and are not signed in, so respondents do not receive authentication cookies. We do not track respondents across sites or build profiles of them.

04Managing cookies

You can delete or block cookies through your browser settings at any time. Because our cookies are strictly necessary, blocking them will prevent you from staying signed in to your account — but public pages and surveys will keep working.
