Privacy Policy

Arch Guide, operated by Arch Guide LLC ("we," "us," or "our"), respects your privacy. This Privacy Policy explains how we collect, use, share, and protect your personal information.

1. Information We Collect

Information You Provide:

Account information (name, email, password)
Profile information (profile photo, bio, preferences)
Photos you upload
Photo library access (Backtrack feature only): if you use Backtrack to identify buildings in your existing photos, the App accesses photos in your device photo library and their embedded metadata (including GPS location and timestamp) and transmits them to our servers to match against our building database using GPS and visual similarity. Photos processed this way are handled the same as other data described in this Policy, including the retention and security practices in Sections 5 and 7
Communications with customer support

Information Automatically Collected:

Location data (GPS coordinates during active tours only)
Tour history (tours taken, completion status, timestamps)
Device information (device type, OS, unique device identifiers)
Usage data (features used, time spent, navigation patterns)
Photo metadata (EXIF data, timestamps, location)
App performance and crash data
IP address

Payment Information: Apple processes all payments. We receive transaction confirmation only — we never see or store your payment card details.

Information From Third Parties:

Authentication data if you sign in with Apple
Aggregated analytics data from service providers

2. How We Use Your Information

We use your information to:

Provide tour navigation and audio guidance
Personalize your experience and recommendations
Display your photos on your profile and the Discover page (if you opt in)
Process subscriptions and manage your account
Send service updates, tour recommendations, and promotional content (with your consent)

3. How We Share Your Information

Your public profile (name, bio, photos)

Service Providers: We share information with the following categories of providers, who are contractually obligated to protect your data and use it only for specified purposes:

Supabase — Backend hosting, database, authentication, file storage
Apple — Payment processing, push notifications, Sign in with Apple, and MapKit navigation and mapping services
ElevenLabs — AI text-to-speech for tour narration
Anthropic / OpenAI (via our Q&A and recommendation services) — AI-powered tour Q&A and content generation. Our "Ask Ellie" feature is scoped to answer questions about the building or architecture currently in view during a tour. It is not designed or intended to provide personal, medical, legal, financial, or other individualized advice, and we discourage sharing personal information in your questions. Questions submitted to Ask Ellie are sent to our AI providers solely to generate a response and are not used by us to build a profile of you.
Spotify / Apple Music — Optional music playback during tours (only if you connect an account)
Crash and analytics providers — App stability and usage analytics

Legal Requirements: We may disclose information if required by law, subpoena, court order, or to protect our rights, property, or safety.

Business Transfers: If Arch Guide is acquired or merged, your information may be transferred to the new entity, subject to this Privacy Policy.

We Do Not Sell or Share Your Data for Cross-Context Behavioral Advertising. Under the California Consumer Privacy Act (CCPA), we do not "sell" or "share" your personal information as those terms are defined. We honor Global Privacy Control (GPC) signals.
