- What changed
- First full policy, listing every cookie the hosted product sets.
This policy covers nitsor.com and app.nitsor.com, run by [Legal entity name]. Neither site uses analytics or advertising cookies. The website sets no cookies at all, and the hosted product sets only the cookies it needs to sign you in and remember your settings.
nitsor.com
The website sets no cookies and writes nothing to your browser's storage. It loads no analytics, advertising or tag-manager scripts. When you send the contact or walkthrough form, your answers go by email, as the Privacy Policy explains.
app.nitsor.com
The hosted product sets these first-party cookies. Each one either handles signing you in or remembers a choice you made. None is shared with an advertiser or used to follow you to other sites. An asterisk stands for the part of a name that varies, such as your account's name in the web address.
On a narrow screen, scroll the table sideways.

Other browser storage
The hosted product also keeps these settings, navigation details and unsaved work on your device. Nothing here is sent to an advertiser or used to follow you to other sites.
On a narrow screen, scroll the table sideways.

Provider pages
Signing in takes you to a page run by WorkOS, and checkout and the billing portal are pages run by Stripe. Those pages set their own cookies under their own policies, and clearing cookies for nitsor.com or app.nitsor.com does not clear them.
Your choices
Because every item listed here is needed for sign-in or for the product to work as you use it, or keeps a setting you chose or work you have not saved, the sites do not show a consent banner. If Nitsor ever adds an optional cookie, such as for analytics, it will update this policy and ask for your consent before setting it.
You can clear or block cookies and site data in your browser settings. Blocking the session cookie stops you from staying signed in, clearing preference cookies resets those settings, and clearing site data can remove unsaved annotation work. Questions go to [privacy contact email].
