Privacy Policy
Last updated: September 6, 2026
This Privacy Policy describes how Serenport Information Technology Inc. ("we," "us," or "our") collects, uses, and protects information when you use the WelcomeGuest platform, including our website at welcomeguest.info, our web dashboard, and our Android TV application (collectively, the "Service").
By using WelcomeGuest, you agree to the collection and use of information in accordance with this policy.
1. Information We Collect
Host account information: When you register as a host, we collect your name, email address, and password (stored as a secure hash). If you register using Google OAuth, we receive your name and email address from Google.
Property information: Hosts provide property details including property name, address, WiFi credentials, welcome messages, house rules, and local recommendations. This information is stored to power the TV display experience.
Booking information: Hosts enter guest names and stay dates to personalize the TV welcome screen. This is referred to as "guest session data."
Device information: When a Google TV Streamer is registered to a property, we collect the device identifier and Firebase Cloud Messaging token to enable remote content updates.
Payment information: Subscription payments are processed by Stripe. We do not store credit card numbers or payment details on our servers. Stripe's privacy policy applies to payment data.
Usage data: We collect basic usage information including device online/offline status, last seen timestamps, and API request logs for operational purposes.
2. How We Use Your Information
- To provide and operate the WelcomeGuest platform
- To display personalized welcome screens on registered TV devices
- To send real-time content updates to TV devices via Firebase Cloud Messaging
- To process subscription payments via Stripe
- To send transactional emails such as password reset links
- To monitor device connectivity and platform health
- To respond to support requests and inquiries
3. Guest Data & Automatic Wipe
Guest session data (guest name and stay dates entered by the host) is displayed on registered TV devices during an active booking. At checkout time, this data is automatically cleared from all TV devices associated with the property.
Guest names and booking records are retained in our database for host record-keeping purposes. Hosts may delete individual bookings from their dashboard at any time.
We do not collect any personal data directly from guests. Guests interact only with the TV display, which is controlled by the host.
4. Data Sharing & Third Parties
We do not sell, rent, or trade your personal information to third parties. We share data only with the following service providers who help us operate the platform:
- Amazon Web Services (AWS) — cloud hosting, database, and caching infrastructure
- Stripe — payment processing and subscription management
- Google Firebase — push notifications to TV devices (Firebase Cloud Messaging)
- Google Play — Android TV app distribution
Each of these providers has their own privacy policy governing how they handle data.
5. Data Security
We implement industry-standard security measures to protect your information:
- All data is transmitted over HTTPS/TLS encryption
- Passwords are hashed using bcrypt with a cost factor of 12
- Authentication uses signed JSON Web Tokens (JWT)
- Our database is hosted on AWS RDS in a private subnet with no public internet access
- API access is rate-limited to prevent abuse
While we take reasonable measures to protect your data, no method of transmission over the internet is 100% secure.
6. Data Retention
We retain your account and property data for as long as your account is active. If you cancel your subscription and request account deletion, we will delete your account data within 30 days.
Booking records are retained indefinitely unless deleted by the host. Guest session data is automatically cleared from TV devices at checkout.
7. Your Rights
As a host using WelcomeGuest, you have the right to:
- Access the personal data we hold about you
- Correct inaccurate information in your account
- Delete your account and associated data
- Export your property and booking data
- Opt out of non-transactional communications
To exercise any of these rights, contact us at privacy@welcomeguest.info.
8. Cookies
Our website uses minimal cookies for authentication (storing your JWT session token in browser local storage). We do not use advertising cookies or third-party tracking cookies.
9. Children's Privacy
WelcomeGuest is intended for use by property managers and hosts who are 18 years of age or older. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected information from a child, please contact us immediately.
10. International Data Transfers
WelcomeGuest is operated from the United States. Our servers are located in AWS us-east-1 (Northern Virginia). If you access our service from outside the United States, your data will be transferred to and processed in the United States.
11. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify registered hosts of material changes by email. The "Last updated" date at the top of this page reflects the most recent revision. Continued use of the Service after changes constitutes acceptance of the updated policy.
