Cookie policy
Last updated 7 September 2026
Introduction
This Cookie Policy explains how DaySync ("we," "our," or "us"), operated by DaySync LLC, a Wyoming limited liability company (Filing ID 2026-001938982), located at 30 N Gould St, STE R, Sheridan, WY 82801, USA, uses cookies and similar technologies.
It applies to our websites and web application, including:
- Our marketing website at daysync.io
- Our web application at web.daysync.io
- Published business booking pages at your-business.daysync.pro
This Cookie Policy should be read together with our Privacy Policy, which explains how we handle personal data more broadly.
What Are Cookies
Cookies are small text files placed on your device when you visit a website. They are widely used to make websites work, to remember your preferences, and to provide information to site operators. We also use similar technologies such as local storage and pixels; in this policy we refer to all of these as "cookies."
Cookies may be session cookies, which are deleted when you close your browser, or persistent cookies, which remain until they expire or you delete them. They may be set by us ("first-party") or by our service providers ("third-party").
How We Use Cookies
We use the following categories of cookies:
| Category | Purpose | Can you turn them off? |
|---|---|---|
| Strictly necessary | Run the Services, keep you signed in, and maintain security. | No — the Services cannot function without them. |
| Preferences | Remember your language choice on the web application. | No dedicated toggle in the panel below — clear them through your browser settings. |
| Analytics | Help us understand how the Services are used so we can improve them. | Yes — on by default; opt out anytime below. |
Strictly Necessary Cookies
These cookies are essential to operate the Services. They include authentication and security cookies that let you sign in and keep your session active. Because they are required, they are not subject to consent and cannot be switched off through our cookie settings.
Preference Cookies
These cookies remember your language choice on the web application, set automatically when you choose a language. They aren't covered by the Cookie settings panel below; you can clear them at any time through your browser settings.
Analytics Cookies
We use PostHog for product and usage analytics. These cookies and similar identifiers help us measure feature usage, activation, and performance so we can improve the Services. Wherever possible, analytics data is used in aggregated or pseudonymized form.
Staying Signed In Across DaySync
To make signing in seamless, we use a session cookie scoped to the daysync.io domain. This keeps you signed in across our marketing website (daysync.io) and our web application (web.daysync.io), so that if you log in on one, your logged-in status is recognized on the other (single sign-on). This is a strictly necessary cookie.
Published Booking Pages (daysync.pro)
Published booking pages at your-business.daysync.pro are public-facing and run on a separate registrable domain (daysync.pro). They do not share the single sign-on session described above. These pages may set their own strictly necessary cookies and analytics cookies.
Third-Party Cookies
Some cookies are set by our service providers:
- PostHog — product analytics, as described above.
- Paddle — when you subscribe through the web application, Paddle may set cookies during checkout for fraud prevention, security, and payment processing. See Paddle’s Privacy Notice for its data practices.
We do not use cookies to sell your personal information or to serve third-party advertising.
Your Choices and Managing Cookies
Analytics cookies are on by default. You can opt out at any time, and change your choices whenever you like, through the Cookie settings link in our website footer.
You can also control cookies through your browser settings, including blocking or deleting cookies. Most browsers let you do this in their settings or preferences menu. Please note that if you block strictly necessary cookies, parts of the Services may not work properly.
Changes to This Cookie Policy
We may update this Cookie Policy from time to time to reflect changes in our practices or applicable laws. We will post the updated policy with a new effective date.
