What is stored in your browser
Cookies are small pieces of data that the browser sends to a site with requests. Local storage keeps preferences on the device. Both can contain identifiers or relate to personal data; they are not necessarily anonymous.
Dymmer uses the following first-party items:
| Name | Purpose and activation | Duration |
|---|---|---|
_dymmer_key |
Session cookie maintaining navigation state, language and access. Required for session features. | Browser session; browser session restoration may prolong its presence. |
_dymmer_web_user_remember_me |
Authentication cookie used when you request remembered access; allows a session to be restored without signing in again. | Up to 60 days from issue or renewal; deleted when you sign out in that browser. |
dymmer-theme |
Local storage of your selected light or dark theme. | No automatic expiry; until you change the preference or clear site data. |
dymmer-project-view |
Local storage of your selected project view, such as table or grid. | No automatic expiry; until you change the preference or clear site data. |
Staff enabling request diagnostics may also use the technical request_logger cookie associated with that diagnostic session. It is not an advertising tool.
External services
hCaptcha, provided by Intuition Machines, loads on access and registration forms to detect automated use and protect the service. It processes browser and connection signals; accessibility features you enable may use technical storage. Its policy distinguishes the embedded service from its own website and dashboard: dashboard cookies are not part of Dymmer's inventory merely because we integrate hCaptcha.
Paying through PayPal takes you to its platform, where its own privacy information applies. Google Fonts typefaces are requested from external servers; that request communicates connection data even if it does not involve a Dymmer cookie. See also our privacy policy.
Mailgun sends transactional emails with open and click tracking disabled. Sending those messages does not embed a Mailgun tracking tool in the browser.
Choice and control
Session features and preferences you request use functional storage. Technologies that are not necessary and require consent must remain disabled until you give it. Continuing to browse or allowing cookies in general browser settings does not constitute that consent.
You can sign out, change display preferences or clear site data in your browser's privacy settings. To remove theme and view preferences too, select site storage, not just cookies. Blocking the session cookie may prevent access and other features; deleting a cookie does not delete your account or invoices.
Dymmer's current code does not include behavioural advertising or cookie-based audience analytics tools. This policy does not authorise their future introduction without the appropriate information and choice. For your rights and how to exercise them, see the privacy policy.
