Cookie Categories
- Necessary : Required for the site to function (e.g., session management, storing your cookie preferences). Cannot be disabled.
- Analytics : Used with your consent to understand how visitors use the site. We use Google Analytics 4 for this purpose; that data is aggregated and anonymous. With your consent we also store on your device, for up to 30 days, the marketing channel that brought you to the site (for example linkedin), read from tracking parameters in the link you followed. If you create an account, that channel is saved with your account so we can see which channels lead to sign-ups, and it is removed from your device. Withdrawing analytics consent deletes it from your device immediately. See Google's Privacy Policy.
- Marketing : Used with your consent for two purposes: (1) identifying registered users to send product updates and email communications (eDM), and (2) measuring the performance of our advertising through Google Ads conversion tracking. Data used for eDM communications is stored internally. Data used for conversion tracking is shared with Google. See Google's Privacy Policy.
What We Store on Your Device
The tables below list what we store on your device and why. Some entries are not cookies but browser storage (local storage or session storage); we list them here because the same rules apply. Retention is the value our code sets, or the provider's documented default for third-party cookies.
Necessary
| Name | Purpose | Retention | Provider |
|---|---|---|---|
| synap_cookie_consent | Stores your cookie choices so we do not ask again | 180 days | Synapsoft |
| locale | Remembers the display language you chose | 1 year | Synapsoft |
| authjs.session-token | Keeps you signed in | 14 days without activity; 30 days at most from sign-in | Synapsoft |
| authjs.csrf-token, authjs.callback-url, authjs.pkce.code_verifier, authjs.state | Carry the sign-in itself: block cross-site request forgery, remember where to return afterwards, and secure the Google sign-in exchange | Until the browser closes; the two Google sign-in values for 15 minutes | Synapsoft |
| synap-site-theme (local storage) | Remembers the theme you selected | Until you clear it | Synapsoft |
| synap-login-email (local storage) | Remembers your email address on the sign-in form, if you asked us to | Until you clear it | Synapsoft |
| synap_internal_traffic | Marks a browser signed in with a Synapsoft account, or an account we have designated as internal (such as a partner's), so that those visits are excluded from our analytics. The value is the single character 1 and holds no identifier | 30 days | Synapsoft |
Over HTTPS the authjs. cookies carry a __Secure- prefix, and the CSRF cookie a stricter __Host- prefix.
Analytics
| Name | Purpose | Retention | Provider |
|---|---|---|---|
| _ga | Distinguishes visitors | 2 years | |
| _ga_<stream id> | Holds Google Analytics 4 session state | 2 years | |
| se_attribution (local storage) | The marketing channel you arrived from, until you create an account | 30 days | Synapsoft |
| se_visitor (local storage) | A random value used only to avoid counting the same browser twice in our daily visitor total. It is not linked to your name, email address or IP address. | Until you clear site data | Synapsoft |
| se_oauth_intent (local storage) | Marks that a Google sign-in started, so it is counted once | Deleted as soon as it is read; if it is never read, 5 minutes later on your next visit | Synapsoft |
| se_email_signup (session storage) | Marks that an email sign-up completed, so it is counted once | Deleted as soon as it is read | Synapsoft |
| se_signup_tracked (local storage) | Your account identifier, so one sign-up is not counted twice | Until you clear it | Synapsoft |
The three se_ sign-in entries are written while you sign in or sign up, whether or not you accepted analytics, and withdrawing analytics consent does not remove them. They hold only a timestamp or your account identifier. Of the entries above, se_attribution is the one we delete the moment you withdraw analytics consent.
Marketing
| Name | Purpose | Retention | Provider |
|---|---|---|---|
| _gcl_au | Links an ad click to a conversion (Google Ads conversion linker) | 90 days | |
| _gac_<property id> | Google Ads campaign and click information | 90 days |
