Cookie policy
Last updated: 9 November 2026
Noosletter uses a small number of cookies, only to keep you signed in and to make features you ask for work. We don't use advertising cookies. On publishers' profile and email pages we ask before we record which pages you visit; that is the banner you see there, and it is separate from cookies.
The cookies we use
| Cookie | What it's for | How long it lasts |
|---|---|---|
App sign-in (set by our sign-in system, names begin authjs) | Keeps publishers and their teams signed in to app.noosletter.com, and protects sign-in forms | Until you sign out, or it expires |
noos_reader | Keeps readers signed in on noosletter.com. It is also set when you open a "read on the web" link from an email, which unlocks that newsletter's gated pages without a separate sign-in. | Up to 90 days |
noos_ref | Set only when you arrive at sign-up through a referral link or a "Powered by Noosletter" badge, so the account that sent you is credited | 30 days |
sidebar_state | Remembers whether the app sidebar is open or closed | 7 days |
Sign-in cookies for the app and for readers are kept separate: one never works on the other's site.
What we store in your browser
On a publisher's profile and email pages we show a banner with Accept and Reject. Only if you accept do we use your browser's local storage (not cookies) for:
| Item | What it's for | How long it lasts |
|---|---|---|
noos_consent | Your choice, accepted or rejected, so we don't ask every visit | Until you clear it, or change your choice from "Tracking" in the page footer |
noos_sid, noos_seen | A random visit code, so the pages you view in one visit are recorded together (and linked to a subscriber if you arrived from their email or later sign up) | A visit ends after 30 minutes of inactivity; the code is replaced on your next visit |
If you reject, neither the visit code nor any identified recording is used. Your choice on the banner is what counts; browser signals such as Global Privacy Control are not read as a choice either way. Only anonymous, cookie-free totals are counted, made from a one-way code that changes every day and can't be linked to a person. See our privacy policy.
What we don't use
- No advertising cookies.
- No analytics cookies. Recording of visits uses local storage, and only after you accept.
- Opens and clicks in emails are recorded against the subscriber they were sent to. Emails can't ask for consent the way a web page can; the privacy policy explains what is recorded.
Your light or dark theme choice is saved in your browser's local storage, not in a cookie.
Managing cookies
You can clear or block cookies in your browser settings. If you block the sign-in cookies, you won't be able to sign in.
