This policy explains the cookies and similar technologies, such as local storage and session storage, used by 8 SIGNS LIMITED ("8 Signs", "we", "us") in our web app at app.8signs.io and on our website at www.8signs.io.
Strictly necessary cookies do not require your consent. All other cookies and similar technologies are non-essential and are used only with your consent or, where the law allows, until you opt out.
In the app, we ask once, when you set up your account, with an optional checkbox that is not ticked in advance. Until you consent, no non-essential item is used. You can change your choice at any time in Me > More > Cookies.
On the website, if your device's time zone is in Europe (including the UK) or Canada, or cannot be determined, we ask before setting any non-essential cookie. Elsewhere, non-essential cookies are on until you switch them off. You can change your choice at any time with Cookie settings at the bottom of every page. We treat a Global Privacy Control signal as a refusal. When you withdraw consent, the non-essential cookies are deleted, although this cannot recall information already sent.
You can also block or delete cookies in your browser. Blocking strictly necessary cookies will prevent you from signing in.
Session cookie. Its name begins with sb- and ends with -auth-token, and it may be split into numbered parts. It keeps you signed in. It lasts until you sign out or your session expires.
Sign-in verification cookie. Its name begins with sb- and ends with -auth-token-code-verifier. It completes sign-in and email confirmation securely. It lasts a few minutes.
Returning browser cookie. Its name is 8signs_signed_in_before. It records that this browser has been signed in before, so that the app opens the sign-in page rather than the sign-up page. It lasts 400 days.
Local storage and session storage. The app keeps your journal notes, saved Discover readings, which feature introductions you have seen, your display theme, a record that your account is linked to its purchases and, if you arrived from our free calculator, the details you entered there, so that the features you use work as expected. These stay on your device and are not sent to us. The calculator details are deleted when you finish setting up your account or close the tab. Everything else is kept until you clear your browser's site data, which also permanently deletes your journal notes.
Unsent Seek question. If you type a question on our website and continue to signup, we store it in this tab’s session storage so you can review it in Seek after setup. The draft expires after one hour and is removed when it is loaded into Seek or when you sign out. We also use account identifiers in this tab’s storage to keep the question with the intended account, and a nonpersonal sign-out marker in local storage to clear old drafts across tabs. The question is not sent to Seek until you press Send.
How you first found 8 Signs. This records the campaign tags in the link you followed, the name of the website that referred you, the page on which you arrived and the time of your first visit, so that we can understand how people discover our services. Until you choose, it is kept in session storage for that browser tab and is not sent to us. If you consent, it is saved with your account until you reject non-essential cookies or delete your account. Otherwise, it is deleted when you finish setting up your account.
Stripe may set strictly necessary cookies in its payment fields to prevent fraud, under Stripe's own privacy policy. Vercel Web Analytics counts page visits without cookies or device storage, after the app has removed identifiers from page addresses, and does not link visits to you. The app uses no advertising cookies, pixels or session recorders.
We use the Meta pixel to measure our Facebook and Instagram ads and to show them to people likely to be interested, and the Google Ads tag, with ad personalisation switched off, to count how many people who clicked our Google ads went on to use the free calculator or open the app. They send Meta and Google the page address, the fact that you used the calculator or opened the app (never your birth details or result), any ad click code, your IP address and your browser and device type.
_fbp (Meta). It identifies your browser so that repeat visits can be recognised. It lasts up to 90 days.
_fbc (Meta). It records that you arrived from a link on Facebook or Instagram. It lasts up to 90 days.
_gcl_au (Google). It identifies your browser so that visits can be linked to ad clicks. It lasts up to 90 days.
_gcl_aw (Google). It records that you arrived from one of our Google ads. It lasts up to 90 days.
_gcl_ls (Google, local storage). It holds a copy of that ad click record. It is kept until you clear your browser's site data or withdraw consent.
Google may set other cookies whose names begin with _gcl_ for the same purpose. Meta and Google may also read cookies they have already set on their own domains, under their own policies.
es8-consent (local storage). It remembers your cookie choice. It is kept until you clear your browser's site data. Framer, which hosts the website, counts visits without cookies.
Meta and Google also use this information for their own purposes, as described in Meta's Privacy Policy (https://www.facebook.com/privacy/policy) and Google's Privacy Policy (https://policies.google.com/privacy), and may process it in other countries, including the United States. In the UK and the European Economic Area, 8 Signs and Meta Platforms Ireland Limited are joint controllers for collecting this information and sending it to Meta, and Meta is responsible for its processing after receipt. Where consent is required, it is our legal basis. Under some US state laws, this may be treated as "sharing", "targeted advertising" or a "sale", and you may opt out with Cookie settings or a Global Privacy Control signal.
We will update this policy before we use any new non-essential cookie or similar technology.
