Cookie policy
Last updated August 17, 2026
Strictly necessary
These cannot be switched off — without them the product does not work. None require your consent under GDPR/ePrivacy, as they are necessary for a service you requested.
| Cookie | Purpose | Duration |
|---|---|---|
authjs.session-token | Keeps you signed in. Set when you sign in with Google. | 30 days, or until sign-out |
dc_viewer | Ties your browser to the one card link you opened, so the open/no counters shown to the sender cannot be inflated by a script. HttpOnly — not readable by page scripts. | 30 days |
NEXT_LOCALE | Remembers which language (Estonian, English or Russian) you last chose. | 1 year |
Functional
| Cookie | Purpose | Duration |
|---|---|---|
dc_consent | Remembers your choice in this cookie banner, so we do not ask again. | 1 year |
Analytics
Only set if you accept them in the cookie banner; you can change your mind at any time. Provided by Google Analytics 4.
| Cookie | Purpose | Duration |
|---|---|---|
_ga | Distinguishes visitors for analytics. | 2 years |
_ga_<container-id> | Persists your analytics session state. | 2 years |
Session storage (not cookies)
To measure how the site is used without setting analytics cookies, we keep two short-lived values in your browser's session storage. They are deleted the moment you close the tab, are never sent to another website, and are never linked to your name or email. Because they do not persist beyond the visit and are not shared with anyone else, they do not require consent — but we list them here so nothing about how we measure the site is hidden.
If you accept analytics cookies, the first of these is not used at all: Google Analytics' own identifier is used instead.
| Cookie | Purpose | Duration |
|---|---|---|
dc_cid | A random number identifying this browser tab, so a visit can be counted as one visit rather than as several unrelated page loads. Not used if you accepted analytics cookies. | Until you close the tab |
dc_attribution | Which link brought you here (for example a campaign tag, or the name of the site you clicked from — never the full address). Tells us which channels are worth continuing. | Until you close the tab |
Controlling cookies
Your browser can block or delete cookies. Blocking the strictly necessary ones will break signing in and card links.
Change your mind
You can withdraw or change your analytics consent at any time. This clears your saved choice and shows the cookie banner again.
