last updated: may 22, 2026

introduction

This Cookie Notice explains how well.software ("well," "we," "us," or "our") uses cookies and similar technologies in the well.software platform and any related applications (the "Service"). It describes what cookies are, what cookies we use, why we use them, and how you can control them.

This Notice supplements our privacy policy, which describes our broader information practices.

1. what cookies are

A cookie is a small text file placed on your device by a website. Cookies allow websites to recognize your device, remember information about your preferences or activity, and provide certain functionality.

Similar technologies, including web beacons, pixels, session storage, and local storage, perform comparable functions and are treated the same way in this Notice.

Cookies may be set by the website you are visiting (first-party cookies) or by third parties whose services we use (third-party cookies). Cookies may be temporary, expiring at the end of your browser session (session cookies), or persistent, remaining on your device for a longer period (persistent cookies).

2. why we use cookies

We use cookies for the following purposes:

  • to authenticate users and secure your session
  • to remember your preferences and settings
  • to operate features of the Service
  • to understand how the Service is used and improve its performance
  • to detect and prevent fraud and abuse

We do not use cookies for advertising. We do not use cookies to track you across other websites or applications.

3. types of cookies

strictly necessary

These cookies are essential to the operation of the Service. Without them, the Service cannot function properly. They include cookies that authenticate your session, prevent cross-site request forgery, and provide the features you have requested. You cannot disable these cookies within the Service, but you can block or delete them through your browser settings, which may prevent you from using parts of the Service.

functional

These cookies allow the Service to remember information about your previous activity, such as your preferred view, default project, or recently visited pages. They make the Service easier to use, but the Service can operate without them.

analytics

These cookies help us understand how users interact with the Service so that we can improve performance and the user experience. They collect information about usage patterns in aggregate. We do not use analytics cookies to identify individual users outside the Service.

4. cookies we use

The table below describes the specific cookies in use on the Service. We may update this list from time to time as we add or remove features. The most current list will always appear on this page.

5. third-party cookies

We use a limited number of third-party services to operate and improve the Service. These may set their own cookies subject to their own privacy practices. As of the date of this Notice, third-party cookies on the Service may be set by our cloud infrastructure provider for load balancing and routing, our analytics provider for aggregate usage measurement, and our error monitoring provider for diagnostic purposes.

We do not allow third parties to use cookies on the Service for advertising or for their independent marketing purposes.

6. how to control cookies

You can control cookies through your browser settings. Most browsers allow you to:

  • view the cookies stored on your device
  • delete cookies individually or in bulk
  • block cookies from specific websites or block all cookies
  • receive a prompt before a cookie is set

Instructions vary by browser. You can typically find guidance under "preferences," "settings," or "privacy" within your browser, or in the browser's help documentation. Common browsers include:

  • Chrome: chrome://settings/cookies
  • Firefox: about:preferences#privacy
  • Safari: Preferences > Privacy
  • Edge: edge://settings/content/cookies

Please note that blocking or deleting strictly necessary cookies may prevent parts of the Service from working correctly, including login.

Where required by law, we will obtain your consent before placing non-essential cookies. You may withdraw your consent at any time by clearing cookies through your browser or by contacting privacy@well.software.

7. do not track

Some browsers offer a "Do Not Track" or "Global Privacy Control" signal that can be sent to websites. Where required by law, we treat such signals as a valid opt-out request for the sale or sharing of personal information and for targeted advertising. As described in this Notice, we do not sell personal information, share it for cross-context behavioral advertising, or use cookies for targeted advertising.

8. changes to this notice

We may update this Notice from time to time to reflect changes in our practices or in applicable law. When we do, we will revise the "last updated" date at the top of the Notice. We encourage you to review this Notice periodically.
