Cookies

A cookie is a small piece of text a website asks your browser to keep, so the site can recognise you on the next page. Synis sets very few, and none of them follow you around the web. This page lists every one, and the switches at the end let you change what you allow.

Your choices

Essential cookies are always on, because signing in is impossible without them. Everything else is off unless you turn it on here.

The cookies we set

• synis_session (essential): keeps you signed in to your workspace. Set when you sign in, sent only to synis.ai, never readable by scripts, and removed when you sign out or the session expires.
• synis_import (essential): lets only your browser see the website import you start before signing up, and attaches it to the account you create next. Never readable by scripts, cleared once the import is attached, and kept for at most 24 hours.
• synis_consent (essential): remembers the choice you make on this page, so we do not ask again. Kept for one year.

What we keep in local storage

Local storage is like a cookie that never leaves your browser. We use it for small conveniences: your light or dark theme, a copy of your cookie choice, and drafts you have not sent yet. None of it is sent to us.

Analytics and advertising

We run no advertising scripts, no tracking pixels, and no fingerprinting. The only measurement tool on this site is PostHog, a European product-analytics provider, reached through our own analytics.synis.ai domain rather than PostHog's — and it only runs once you turn on Analytics above. It records the pages you view, not what you click; it does not run on this site at all until you opt in, and switching it off removes it immediately. This switch is about your browser only: separately, our servers send PostHog a few product usage events for every account, such as sign-ups and job outcomes, never your content. The Privacy Policy describes them. Turning analytics on sets a cookie and a matching local storage entry named ph_<project-key>_posthog, which PostHog uses to recognise you between page views.

Cookies from other companies

• Polar sets its own cookies on the checkout and billing pages it hosts, to process payments and prevent fraud. Those pages are Polar's, under Polar's privacy policy.
• Social platforms set cookies on their own sites when you connect an account. Synis receives an access token, not their cookies.

Clearing cookies yourself

Every browser lets you see and delete cookies for a site, usually under Settings and then Privacy. Deleting ours signs you out and brings the cookie notice back. Blocking the essential cookie stops sign-in from working, and there is no way around that.
