1. About This Policy
This Cookie Policy explains how Arch uses cookies and similar browser technologies when you visit our website, use our wedding planning platform, access a wedding website created through Arch, or respond to a wedding invitation.
Arch is operated by Arch Wedding Ltd, a company registered in Scotland under company number SC906671.
Our website is https://archwedding.com.
For questions about cookies or privacy, contact support@archwedding.com.
This policy should be read alongside our Privacy Policy, which explains how we collect, use, share and protect personal information.
3. How Arch Uses Browser Storage
Based on our current technical implementation, Arch uses browser storage for authentication and first-party functions. The identified keys are: the sign-in session key set by our authentication service (sb-…-auth-token); aisle.referral (supplier referral attribution, local storage); aisle.returnTo (where to return after signing in, session storage); aisle.perksSeenAt and aisle.perksHintShownAt (interface state, local storage); aisle.perksHintSession (interface state, session storage); aisle:sev:{type}:{slug} (first-party supplier impression de-duplication, session storage); and stationery-draft:{key} (in-progress stationery designs, session storage). These keys are not sent to third-party advertising or marketing platforms by Arch’s identified application code.
Account authentication
When you sign in to an Arch account, our authentication service uses browser local storage to maintain your authenticated session and support token refresh.
This enables couples and suppliers to remain signed in while using their accounts.
This storage is used for authentication and account security, rather than advertising or behavioural tracking.
Authentication information may remain in browser storage until you sign out, the session expires, or the information is otherwise removed.
Secure RSVP sessions
Arch has technical support for a short-lived, secure RSVP session cookie named __Host-arch_rsvp.
This cookie is designed to maintain an authorised RSVP session and has a maximum lifetime of two hours.
It is configured with security protections including HttpOnly, Secure and SameSite=Strict.
This cookie is not used by Arch’s current direct invitation-link and QR-code RSVP experience. It belongs to a separate verified-session feature that is currently disabled.
Direct invitation links and QR codes
Guests can respond to invitations using the unique link or QR code supplied by the couple.
This direct RSVP process does not require guests to create an account, provide an email address or complete email verification.
The invitation’s access credential is contained in the unique RSVP URL rather than stored in an RSVP session cookie.
Guests should treat their invitation links as private and avoid sharing them with people who should not have access to their household invitation.
6. Analytics and Advertising
At the time of our most recent technical review, Arch’s application code did not contain implementations of:
- Google Analytics or Google Tag Manager.
- Meta Pixel or other social media advertising pixels.
- Third-party product analytics platforms such as Mixpanel, PostHog or Hotjar.
- Advertising or behavioural tracking cookies.
- Application-defined marketing attribution cookies.
Arch does not currently use these technologies in its identified first-party application implementation.
If we introduce non-essential analytics, advertising or similar tracking technologies in the future, we will assess the applicable legal requirements and implement any necessary consent or objection controls before using them.
We will update this policy accordingly.
8. Managing Browser Storage
You can manage or remove cookies and stored website information through your browser settings.
Most browsers allow you to:
- View and delete cookies.
- Remove stored website data.
- Block cookies from particular websites.
- Restrict third-party cookies.
- Clear browsing data.
Please be aware that deleting or blocking essential authentication storage may sign you out of Arch or prevent some account functions from operating correctly.
Cookies used by Google, Apple or Stripe may also be subject to the settings and controls provided by those services.
9. How Long Is Information Stored?
Different technologies have different storage periods.
Arch’s ordinary direct-link RSVP process does not require an RSVP session cookie.
We will review this information when our integrations or technical implementation change.
10. Changes to This Policy
We may update this Cookie Policy when we change our services, introduce new technologies or need to reflect changes in applicable law.
The latest version will be available on our website, with its updated effective date.
Where a change requires consent or another specific user control, we will implement that requirement as appropriate.
