Cookie Policy
Last updated: September 30, 2026
1. What are cookies?
Cookies are small text files that a website stores in your browser. Similar technologies, such as the browser's local storage, work in a similar way; this policy covers both.
2. How we use them
2.1 Essential cookies
These are needed for the site to work: they remember your language, keep you signed in to the dashboard and protect the sign-in against forged requests. They do not require consent.
2.2 Analytics cookies
Google Analytics cookies help us understand how the site is used. They are set only after you click "Accept" in the cookie banner, and never on the dashboard, on shared message links (/m/…) or on test reports (/test/…). Advertising features and Google signals are disabled.
3. Cookies and storage we use
Essential items need no consent; analytics cookies are set only with your consent.
| Name | Type | Purpose | Duration |
|---|---|---|---|
| NEXT_LOCALE | Essential | Remembers the language you chose. Set only if it differs from your browser's language. | Session |
| __Secure-authjs.session-token | Essential | Keeps you signed in to the dashboard (encrypted, not readable by scripts). Only when you are signed in; a large session may be split into .0, .1 parts. | 8 hours (renewed while you use the site) |
| __Secure-authjs.callback-url | Essential | The page to return to after signing in. Set by the sign-in system when a page checks whether you are signed in. | Session |
| __Host-authjs.csrf-token | Essential | Protects signing in and out against cross-site request forgery. Set by the sign-in system when a page checks whether you are signed in. | Session |
| __Secure-authjs.state, __Secure-authjs.pkce.code_verifier | Essential | Secure the sign-in with auth.gobird.io. Set only while you are signing in. | 15 minutes |
| mailaudit-consent | Essential (local storage) | Stores your cookie choice. Kept in your browser's local storage, not as a cookie; we ask again after 12 months. | 12 months |
| _ga | Analytics | Google Analytics: distinguishes visitors. Only after you accept. | 2 years |
| _ga_VHBCYWYD1Z | Analytics | Google Analytics: keeps the session state. Only after you accept. | 2 years |
4. Google Analytics
Google Analytics is provided by Google Ireland Limited (Ireland) and Google LLC (USA). Its data may be transferred to the United States; Google LLC has certified its adherence to the EU-U.S. Data Privacy Framework. More information: policies.google.com/privacy.
5. Managing your choice
You can change or withdraw your choice at any time with the "Cookie settings" link in the footer or the button below. Once you withdraw consent, Google Analytics stops sending data and we delete its _ga cookies from your browser.
Your browser also lets you:
- View the cookies stored on your device and delete them individually
- Block third-party cookies
- Block all cookies from specific sites
- Block all cookies from being set
- Delete all cookies when you close your browser
If you block essential cookies, signing in to the dashboard will not work.

We may update this Cookie Policy from time to time. The date at the top shows the latest version.
