This is an English translation provided for convenience. In case of any discrepancy, the Dutch version prevails.
Certly uses as few cookies as possible. We place functional cookies that are needed to log in and keep the website secure. In addition — only with your consent — we place cookies for anonymous statistics, so we can see how the site is used. We use no advertising cookies and sell no data to third parties.
What are cookies?
Cookies are small text files stored on your device when you visit a website. Functional cookies are necessary for a website to work; the law requires no consent for those. Analytical or marketing cookies do require consent — which is why we ask for it first via the cookie notice.
Which cookies does gocertly.com place?
| Name | Purpose | Retention |
|---|---|---|
| next-auth.session-token | Keeps you logged in (session) | 30 days |
| next-auth.csrf-token | Protects forms against abuse (CSRF) | Session |
| next-auth.callback-url | Sends you to the right page after logging in | Session |
| certly-cookie-consent | Remembers your choice in the cookie notice (local storage) | 1 year |
Statistics (only with consent)
If you choose "That's fine" in the cookie notice, we load measurement cookies via Google Tag Manager that let us see anonymously which pages are visited and where the site can improve. If you choose "Essential only", these cookies stay off — Certly works fully either way. We pass your choice on via Google Consent Mode: without consent, all measurement signals are set to "denied". See Google's privacy policy.
Exact cookie names may get a prefix such as "__Secure-" depending on your browser and security level.
Payments via Stripe
When you take out a subscription, you are redirected to Stripe's secure payment environment. Stripe places cookies on its own domain that are needed for payment and fraud prevention. See Stripe's privacy policy.
Chat via tawk.to
The website has a chat button you can use to ask us a question directly. That chat runs on tawk.to. As soon as the page loads, tawk.to places a few functional cookies (such as TawkConnectionTime and twk_idm_key) to keep your conversation together during your visit and to recognise you on a return visit, so you don't have to start over. No advertising or tracking cookies are placed. What you type in the chat is processed by tawk.to and passed on to us. See tawk.to's privacy policy. When you are logged in, we pass your name, email address and organisation name to the chat so we don't have to ask who you are — see the privacy policy.
Deleting cookies
You can always delete or block cookies via your browser settings. Note: without functional cookies you cannot log in to Certly.
Changing your choice
Want to withdraw or give your consent after all? Delete the local storage for gocertly.com via your browser settings (or clear your browsing data for this site); the cookie notice will reappear on your next visit.
