Cookie and Browser Storage Policy
Effective October 8, 2026
cookies-2026-10-08-v1
KeepCarrier uses necessary browser storage for requested service and a separate choice for optional website attribution. Accepting Terms or opting into product emails does not accept optional cookies. You can choose necessary-only and still use the website, signup and purchased service.
Necessary storage
Session and short-lived verification cookies support sign-in, secure signup and recovery. Preferences support theme, timezone and roster presentation. A protected trial-device hint can last up to 180 days and supports repeat-trial abuse protection. Browser storage may also preserve user-entered form preferences. These do not authorize unrelated advertising tracking.
The signed kc_cookie_choice cookie retains the current optional-attribution choice for up to 180 days, and a minimal server record retains its opaque event ID, policy version, choice and time. It is not a working-account credential and does not grant trial or paid access.
Optional attribution
Only after an affirmative current choice, kc_ft records the first marketing source for up to 90 days, kc_lt the latest source for up to 30 days, and kc_seo_landing an organic landing for up to 30 days. They can contain sanitized campaign tokens, referring host, landing path and time. Although they omit raw passwords and full query strings, they may be linked to signup attribution and should not be described as always anonymous.
Optional attribution is off until accepted, and refusal or a Global Privacy Control signal prevents it. Withdrawing the choice removes those browser cookies and stops their further use. Historical lawful aggregate records are subject to the Privacy Policy, not silently rewritten. We do not use third-party advertising cookies or sell this information to an advertising network.
Your controls
Use Cookie settings on the public website to accept optional attribution or choose necessary-only. You can change the choice later; a materially changed purpose or expired choice requires a new choice. Browser blocking or deletion is also available, but blocking necessary session cookies prevents sign-in. Changing cookies does not renew an expired trial or remove retained commercial evidence.
